Judging lighting I had the honour of being a judge at the 2010 Eskom Energy Efficient Lighting Awards recently and was blown away by some of the designs and ingenuity of the entries presented there. Some entrants interpreted the brief so creatively and had obviously spent much time and effort on the concept, design and execution of the competition instructions and guidelines. The originality and ingenuity of the entries really encouraged me: this is the next layer of designers and creators that we will see in the interior architecture and design arena and they promise to have a bright future! Some gave real thought to the marketability of the product and budget, mass production, labour intensive manufacture and precision went into the product design documents. The student entries are a testament to the lecturers who have embraced this competition and pushed, encouraged and motivated their students to deliver world class designs. I salute you all for your tremendous hard work and the difference you make to the future of our design and architecture industry! You will see one of the designs, Lanterna by Sanet Stegman on page 14. Other designs entered are featured on page 4. We will bring you the final winners and other entries in our Jan/Feb issue after the awards evening has taken place in November.

Eskom Energy Efficient Lighting
Awards entries Almost two hundred entries were received for the Pretoria chapter of this year’s Eskom Energy Efficient Lighting Awards. The goal of the energy efficient lighting design competition is to demonstrate that efficient lighting technologies, such as discharge, fluorescent and LED technologies, can be used in very contemporary and attractive luminaires and lighting design systems intended for residential lighting. The quality and standard of entries were very high and had the judges chattering with excitement. “The creativity and execution of the brief was fantastic. This was the
first year I had the honour of judging the awards and I was astounded by some of the entries. Some lamps literally gave me goose bumps!” commented WALLS&ROOFS editor, Marlene van Rooyen. “The originality and ingenuity of the entries really encouraged me: this is the next layer of designers and creators that we will see in the interior architecture and design arena and they promise to have a bright future! Some gave real thought to the marketability of the product and budget, mass production, labour intensive manufacture and precision went into the product design documents.” The final award winners will be announced on 4 November in Johannesburg.

products
from an old favourite
Saint-Gobain Weber recently introduced its new packaging to the market, along with several new products that expand the company’s offering to its customers. “We have updated our packaging to consolidate our branding across our various product categories,” says Aldrin October, Weber’s divisional commercial manager. “Tylon, known to South Africans as the leading tile adhesive brand which was bought by Weber a few years ago, has now been fully incorporated into Weber’s branding and packaging guidelines. This makes it easy for our customers to identify our full range of adhesive and finishing solutions.” Aldrin explains that Weber’s packaging has changed to make it more convenient for clients. “For example, our new grout packaging is a new plastic waterproof pack, and has a transparent window through which customers can see the colour of the grout. It also has finger holes along the top, which makes it much easier to handle. Changing our packaging is also part of the process of complying with the anticipated Consumer Protection Act,” says Aldrin. Several new products In keeping with the fresh new look at Weber, the company has also officially launched several new products. Weber Brush Coat is targeted at the affordable housing market, and is an all-in-one solution that offers a waterproof aesthetically pleasing finish when applied directly to bricks and plastered surfaces. Weber Colour Silk is a cement-based, Left: The new grout packaging is waterproof and also has finger holes along the top, making it easy to carry.

pigmented wall covering that offers a unique textured appeal in a range of colours, eliminating the need for painting. This product can also be applied onto drywalling. “We have also launched Weber Grano Colour, a floated, cementbased, pigmented flooring product that is applied into wet screeds or cement. It is available in a range of colours and offers a natural appeal that eliminates the need for other floor finishing,” explains Aldrin. Weber Pool Paint is a do-it-yourself swimming pool renovation product, perfect for giving gunite or plastered residential pools a facelift ahead of the summer season. Weber Waterproof is a DIY kit suitable for shower cubicles. However, the kit may also be used on a commercial level for walkways, balconies and staircases.

St Cyprian’s in Cape Town comprises a set of classical buildings with predominantly high-pitch roofs. In order to ensure 100% insulation coverage, a flame-retardant, loose-fill cellulose was used.
Turnkey insulation solutions at upmarket Cape Town school
Quantity surveyors Riverside Consulting recently specified Eco-Insulation for the refurbishment of an upmarket school in Cape Town. The school, St Cyprian’s, is one of the leading South African girls’private schools and has a bold aim to create future leaders. Local firm Noero Wolff are lead architects on the project.
The school comprises a set of classical buildings with predominantly high-pitch roofs, not easily accessible from inside. Professional installer Richard Ellis needed to remove roof tiles in order to gain access from above. “Eco-Insulation has once again demonstrated its versatility,” said Ellis. Due to the specialised delivery system of Eco-Insulation, the product may be pumped several storeys into the most inaccessible of attic spaces. The science and language buildings of St Cyprian’s were being insulated and the Eco-Insulation pump was set up on a lower level. Once the product hits the top of the ceiling inside the attic, it automatically spreads out, filling all available recesses to ensure 100% coverage. “This is highly important since uninsulated areas of ceiling cause hot spots that can reduce the efficiency of the thermal envelope by dramatically more than their relative proportion,” explains Ellis. Although not a unique product from the international perspective,
it was adapted to local conditions. The pump used to deliver product above the ceiling area at St Cyprian’s, for example, was specially developed by founder Cecil Homan at the company's factory in Cape Town. Eco-Insulation is favoured by many specifying professionals because the turnkey service reduces the additional worry of relying on general building contractors to interpret the insulation's technical requirements and undertake the installation. Eco-Insulation is a flame-retardant, loose-fill cellulose product manufactured locally from recycled newsprint. Eco-Insulation is approved under SABS 1381-6 and therefore displays the SABS mark.

New roof insulator launched
Recently installed Eco Shield under-tile insulation material shown on one of the houses at a new cluster development in Midrand.
WiththelaunchofEcoShield,theroofinsulatorbrandfrom INFRASETBuildingProductsforresidential,commercialand industrialbuildings,thisproductwillcontributetomaking any habitable structure SANS 204-compliant.
Agrément-approved and conforming to the local standards, Eco Shield works by providing a radiant barrier under the roof covering, thereby saving energy and creating comfortable living and working environments. Available in four grades, namely domestic, commercial/light industrial, heavy industrial and under-tile membrane, Eco Shield is manufactured by laminating a reflective aluminium foil to a polypropylene spunbond membrane. All grades are designed for pitched roofs apart from the heavy industrial model which is meant for open steel-framed structures such as factories and warehouses.

comments that against a backdrop of ever-increasing electricity rates and carbon footprint concerns, energy-saving measures have become imperative. “Installing a radiant barrier such as Eco Shield makes perfect environmental, not to mention economic, sense,” he says. “Roofs absorb solar energy which is radiated downward. Eco Shield’s reflective insulation system offers a permanent method of blocking this downward transfer into buildings. Radiant barrier systems such as Eco Shield have high reflectivity and low emissivity rates, which reduce heat transfer by ‘bouncing’ up to 97% of all radiant energy back through the roof tiles in summer. In winter months internal warmth is reflected back into houses and other structures. “Properly installed, Eco Shield will provide many decades of maintenance-free service. Moreover, due to its energy-saving properties, it offers a quick return on investment,” advises Uys. Eco Shield is installed like any under-tile membrane – over the rafters and stapled into place. The membrane must protrude beyond the walls or feed into the gutter to allow for run-off. Special care must be taken not to damage the membrane during installation as this will reduce its emissivity properties and efficiency. Should any damage occur it should be repaired by the contractor to the recommendations of the manufacturer. INFRASET Building Products has published a brochure on Eco Shield which, besides describing the benefits of the product, provides information and diagrammatic illustrations of the various installations.

Designer tin tables show
true South African culture Vitreous enamelled steel product leader Vitrex recently partnered with Architect Paul Whitehead of Osmond Lange Architects to create the TinTable. Looking to design precedents and historic enamelware, the
ubiquitous enamelled kitchen table of 70 years ago was the inspiration for this product that was launched at Decorex 2010. The TinTable range of designs is utilitarian, clean-cut and acknowledges the unique South African use of tin plates, tin mugs and other enamel tableware. The products offered are intended as designer items made in limited production runs or custom art pieces and once-offs, although they are ideally suited for domestic and commercial applications due to their durability. For more information, visit www.tintable.co.za, to which full thanks and acknowledgement are given.
Fashionable window coverings Over the years Hunter Douglas has brought an incomparable element of fashion and design to South African homes through its extensive, high-quality sales programme of window coverings. Incorporated into this extraordinary variety of options to meet the most exacting requirements of architects, interior designers and discerning homeowners is the Luxaflex Shutters range which has proved to be a popular product for today’s homes. These shutters offer versatility to enhance every décor with a custom look that provides exceptional light control and complete privacy, with the ability of closing tightly in both directions. From traditional to contemporary, Luxaflex Shutters enable the provision of designs for every type of window, from formal living rooms to children’s playrooms – even in busy kitchens and steamy bathrooms – and once the design is decided upon, delivery takes place within days. Luxaflex Shutters are energy-efficient, with a hollow design that provides an excellent insulation barrier. They are fire-retardant, selfextinguishing and, as they have no cords, they present no child hazard. Their non-porous, non-absorbent and permanent finish is resistant to dents and scratches, mould and mildew, and its lightweight design is virtually indestructible and will not warp, shrink, chip, crack, peel or fade – and never needs painting. Maintenance is also simple, because Luxaflex Shutters are easily cleaned with soap and water. The elliptical-shaped louvres are available in three sizes – 63mm; 89mm; and 114mm widths – and they rotate fully in both directions when activated, as well as being evenly andac-
curately spaced to create a uniform look from shutter to shutter. The rotation system is of traditional tilt-bar design to provide an immediate, tight and uniform closure of all louvres. Available in five different frame options, these shutters can also be provided with a standard hinge system, a bi-fold or bypass tracking system, or in a French door configuration. Luxaflex Shutters provide a fashionable, clean look with superior durability. They are designed for quick installation and will add a relaxed sense of luxury to virtually any room – with the assurance of years of great performance.

Lanterna interprets lanterns as an historic lighting source into a modern context using modern materials and replacing the light source with LEDs.
Modern lantern design from SA design student Lanterna, a simple, lightweight and practical LED lighting productintheshapeofakerosenelantern,recentlyreceived a special Award at the 2010 Eskom Energy Efficient Lighting Design competition. Designed and constructed by Sanet Stegmann in her final year of her first degree in Interior Architecture at the University of Pretoria, the product got judges and colleagues to take note of what local design students are producing. “My goal was to create a compact and portable, modern lamp,” explains Stegmann. “I took a look at what the common problems are associated with the traditional lantern, and what could be done to solve them, whilst contributing to the energy-efficiency drive.” Acknowledging the history and practicality of this light source, Lanterna interprets this historic lighting source into a modern context using modern materials and replacing the light source with LEDs. The product

has a minimalistic, clean-cut look, consisting of 2 steel frames that are fastened at the top and bottom to form a flush joint. The connection point is specifically off-centre, a deliberate design decision adding to the aesthetic and practical quality of the lamp, as it creates a gap where one’s fingers can be inserted, enabling easy transportability. Mobility is further achieved through the use of a rechargeable battery as energy source to the LED strips used within the structure. When fully charged, Lanterna can illuminate for over 24 hours. Lanterna provides directional lighting and a soft hue. It can be used in other contexts as it is not restricted by the use of cabling. “I experimented with a variety of materials to see what types of lighting could be created. There are also outdoor possibilities when the lamp is made of polyethylene.” The product’s name, Lanterna, is derived from the Italian translation of the word “Lantern”. “It was inspired by the hurricane lamp as practical lighting solution dating back to the 18th cen. The hurricane lamp was used for hundreds of years as a source of light before gas and electric lighting were developed,” says Stegmann. “Today we need to turn to more energy-efficient lighting solutions that are not only practical but promote sustainability,” concludes Stegmann. Technical datasheet of Lanterna Mounting: Table Dimensions: 90 x 163 x 280mm Finish: Powder-coated mild steel, shade available in wood veneer, ceramic, mild steel Description: Mobile luminaire providing directional lighting Electrical: Supply: Rechargeable lithium-ion battery (will illuminate for over 24 hours when charged) Lamp: 12 – 15 LED strips Voltage: 12 Volt

A creatively themed shopping centre:
Loop
in Weiterstadt
Loop 5, one of the first themed shopping centres in Germany, was designed by HPP Architects who decided to design the building according to the captivating idea of“Air Travel”. Every aspect, from the industrial location that has no urban relationship, to the façade that recreates a jewellery box, is creative and different to other shopping centre designs.
in Darmstadt. The architecture and creativity carries the message of aviation and the centre’s content sets the scene for a unique emotional shopping experience. Recognisability The shopping centre is 320m x 150m tall and consists of two full storeys, one underground level and a roof storey as well as a nine-storey car park. The two buildings are connected by bridges and by a supply road at the underground level. The two structures are also architecturally united by rounded corners and vertically textured running façades. According to HPP, the exterior image of the shopping centre grew out of the concepts of “speed” and “jewellery box”, with sand-coloured façade panels that allow a view of the permanently changing colour of the building shell. “The façade is made up of panels of differing widths which suggest speed and the brightly coloured joints suggest the precious stones in
Photo © de.wikipedia.org
Accessibility, uniqueness and recognisability The centre covers over 100 000m2 of ground floor area and it is situated between Frankfurt and Darmstadt. According to HPP Architects, accessibility, uniqueness and recognisability were the key themes of the brief with which Portuguese specialist shopping centre developer Sonae Sierra approached HPP in the middle of 2006. Besides accessibility, uniqueness and recognisability, the architects were also tasked with designing a centre that would attract visitors from beyond the anonymous industrial location where Loop 5 was to be built. Themed shopping centres are still in their infancy in many parts of the world and, in Germany, functionalistic shopping centre layouts still prevail. The architects hope that the design of Loop 5 will serve as a catalyst for this genre and also that it will function as a unique landmark for the region. The theme of “Air Travel” arose out of the shopping centre’s proximity to Frankfurt Airport and the ESOC (European Space Operations Centre)

These design elements reach their beautiful conclusion in the perforated metal of the crown that sits atop the building and provides the stage, both day and night, for a sparkling show of light and shadow,” say HPP Architects. Accessing the shopping centre Loop 5 was constructed in the form of a ring mall and three sets of escalators connect the lower ground floor with the other floors that connect the shopper to the rest of the centre. Three of the nine levels have a direct link to the shopping centre, either via bridges or the supply road. On the remaining six levels visitors enter the centre via the six groups of lifts that bring them out directly at the shopping level they require.

by the idea of aviation. Propellers, wings, rudders and rotors along with the graphics in the wall coverings and the flooring represent different stages of aviation, from the golden age of flying and to the jet age. “Jet Set”, “Contemporary Aviation”, “Pioneering Flight” and “Golden Era” are the sub-themes that are communicated through the four different adventure areas. The different areas are themed by means of colour, materials and various interior finishes. Each detail of Loop 5 evokes emotions that draw visitors to the ideal of flying. “Loop 5 follows the trend of turning shopping into an emotional experience and, as one of Germany’s first to be themed, belongs to the next generation of shopping centres. Since it opened at the beginning of October 2009, Loop 5 has already become one of the biggest attractions in the Rhine-Main Region,” conclude HPP Architects.

Green,futuristicspaceportinNewMexico TheNewMexicoSpaceportAuthorityBuildingisthe first private spaceport in the world that will send people into space for seven minutes at US$200 000 per trip. Foster + Partners and URS Corporation won an international competition to build the project, which seeks to capture the drama and mystery of space flight and the thrill of space travel.
A comfortable thermal mass of the building, which buffers the building from temperature extremes, is achieved through the low-lying form which is dug into the landscape.
Virgin Galactic invested over US$300-million in developing Spaceport America. Sir Richard Branson’s Virgin Group launched Virgin Galactic in 2004 with the objective of developing commercial space vehicles that would transform the safety, cost and environmental impact associated with manned space travel (www.spaceportamerica.com). The facility is over 110 000m2 and, according to www.spaceportamerica.com, extensive use of sustainable and clean energy technology throughout the design ensures that the spaceport will set the standard for environmentally sound design for similar structures in the future. The project sets out to make a minimal impact on the environment, using local materials and regional construction techniques that are both sustainable and sensitive to its surroundings. The scheme was also
designed to achieve the prestigious U.S. Green Building Council’s LEED Platinum accreditation due to its low energy requirements and minimal embodied carbon during construction. The comfortable thermal mass of the building, which buffers the building from temperature extremes, is achieved through its low-lying form which is dug into the landscape. The building was angled so that westerly winds are caught to increase ventilation and natural light enters the building via skylights. A glazed façade was reserved for the terminal building, establishing a platform for the coveted views onto the runway. The facility also houses earth-tubes that pre-condition the air to reduce HVAC costs by 50 – 70% and solar thermal panels on the roof for hot water to the embedded in-floor loop system. The building is set low within the desert-like landscape of New Mexico and it can be seen from the historic El Camino Real trail. On arrival, the visitors, space tourists and astronauts are met with a building that has been designed to relate to the dimensions of the spacecraft. The designing team went to extreme measures to ensure a highly efficient and rational balance as well as to create a careful balance between accessibility and privacy. Visitor spaces are integrated with the astronauts’ areas to convey the excitement of space travel while more sensitive zones (such as the control room) are visible without providing too much access. An exhibition space that documents the history of the region as well as a history of space exploration is formed with retaining walls. Visitors can travel through a strong linear route to the ‘superhanger’ that houses a simulation room and spacecraft.

Interior space solutions for commercial projects Interior designers and architectural firms often have to meet clients halfway when it comes to the overhaul of corporateofficesandcommercialprojects.Re-evaluatingworkplacestrategies,incorporatingnewtechnologies, reducing costs and planning an efficient as well as creative workplace are not without their challenges.
Trends in the workplace Nicole Maguire, a Managing Member of Nimrod Design in Johannesburg, says that one of the trends in interior design for corporate clients is the way in which companies are focusing on their staff. According to a survey done by architecture firm Gensler, half of all employees said they would work an extra hour per day if they had a better workplace. “In the past, corporate clients were more concerned with their outward appearance and how visitors perceive their premises. Today, they are focusing on creating awesome working environments for their staff,” says Maguire before explaining how companies are incorporating leisure and lifestyle into their corporate offices. “We recently installed pool tables and foosball tables in a company’s call centre, for example. Companies know that people often have to travel far to work and spend a lot of hours in their work environment, so they are trying to make it as comfortable and homely as possible,” says Maguire. Celia Marussi, Designer at Nimrod Design, says that new research has also shown how different space usage increases productivity

amongst staff. “We recently saw a presentation from a well-known office furniture sales representative that explains why larger boardrooms aren’t the ideal way to conduct meetings,” says Marussi. “The study shows that the most effective and successful meetings are conducted between a maximum of 6 people. A lot of huge boardrooms are unused these days and smaller boardrooms are becoming more popular. Another trend amongst corporate clients is having more informal breakaway areas where people can have meetings, instead of a larger, dedicated space.” According to ORGATEC, an important characteristic of the facility furniture of the future is its ability to change. “It must be able to adjust itself to its surroundings. This is why many products are not made specifically for either the private home or for the office and other public spaces,” says ORGATEC. Office furniture is becoming cosier and household furniture is increasingly following the lead of office furniture in terms of quality and the requirements it must fulfill (www.orgatec.com). An example of this is individual seating elements that can be combined as desired so that seating requirements can be changed depending on the function. “This allows open areas of communication to be created and structured. And it’s just as easy to transform reception areas into dynamically

defined and relaxed waiting areas. In addition, the simple and mobile arrangement of the seating elements allows for many new combinations, can be adapted to different requirements and can change the overall effect of a room,” said ORGATEC. Flexible space designs Craig Krull, Director of .able walling solutions, says that quality of workmanship and extended time lines are major challenges for interior designers working with drywalling. “Interior designers still using the throw away drywalling systems are not offering their clients the best solution possible. Besides the slight cost difference, demountable panels can just about do anything drywalling can. “.able’s new systems offer a truly competitive product to drywalling. These products can of course be changed year after year, and are expected to last over 10 years. Even after that it still has value when we scrap it.
.able’s renowned demountable walling and screening system, system 5zero, caters specifically for high churn installations in the workplace. “Many environments need to churn, especially in large corporate companies where different departments are predicted to grow within a certain amount of time. Interior designers need to provide for these changing spaces and it has been proved that demountable walling is the solution. It is designed to capture the mood of the environment and installed easily into necessary spaces. Clever reductions of certain elements have led us to be able to reduce critical component costs by more than 25% on our new LITE version,” says Krull. Flexible walling solutions, such as demountable partitions and translucent panels that can be transformed into walls, dividers and doors, are also offered by Ergosystem. The systems range from functional visual and acoustic barriers to purely decorative backdrops that can open and close spaces within corporate and retail environments. “Functional elements such as whiteboards, pinboards, accessory rails which can accommodate storage units for files and papers can be added to these walling systems and many of them are fully stackable,” says Dean Armstrong, Managing Director at Ergosystem.

Planning and moving areas with demountable walling makes the process much more efficient, as there are no repairs required to the ceiling, or the flooring, and of course there’s little to no dust or noise.”
Continued from page 21 Time constraints Krull explains that completion deadlines also create a variety of problems for interior professionals. “When corporate offices relocate, they usually need everything done immediately. Problems may arise if all the factors of breaking, moving and building new offices and spaces are not fully taken into consideration. Planning and moving area’s with demountable walling makes the process much more efficient, as there are no repairs required to the ceiling, or the flooring, and of course there’s little to no dust or noise.” Marussi comments that lead times when ordering products from overseas can also add to the stresses. “It takes about 12 weeks to order furniture and design products from overseas and very few clients want to wait that long.”

Stretch ceilings One of the products that Nimrod Design has recently started using is the Barrisol Ceiling. This high-performance flexible panel has been called the “liquid ceiling” and it is the ideal product for designers to really unleash their imaginations. “The product was launched about 35 years ago by the owner of Barrisol and an architect,” says Roger Bax de Keating, Director of LEBAXPIN Pty Ltd in South Africa. “The goal was to be able to give interior designers and architects a way to add feeling through a variety of colours and shapes to ceilings, which was difficult at the time. It took over 10 years to develop the product and today it is available in a wide range of colours.” The product is lightweight, recyclable, lead-free, durable and weighs 20 times less per project than a standard ceiling construction. These stretch ceilings have been successfully used in Europe for over 30 years and they have reaped in an array of awards that elevated them as the most award-winning ceiling in the world. Some of them being the 1998 Construction Excellence Award – CISCA USA, the Gold Medal at the Construction Expo in Romania in 2001, the Avant-Garde Product at Arch 2001 in the Czech Republic, and many more. It comes with a 10-year guarantee. Barrisol Ceiling Systems can be used both for creative lighting, and for functional lighting. Spotlights can also be mounted into the ceiling systems and LED systems, as well as backlighting and strip lights, can also be incorporated (www.barrisolgrg.co.uk). Some have acoustic properties. According to Bax de Keating, another reason for the creation of the Barrisol ceiling was to provide a ceiling material that is environmentally friendly. “The ceiling is completely recyclable and does not need water in its construction. It is easy to install in spaces without disrupting people in the area. It does not require maintenance, does not need painting, is dustless and clean to install. Is waterproof, can easily be removed and replaced as many times. It has also been installed in operating theatres, hospitals, gyms, kitchens and bathrooms because it is hygienic and easy to clean,” he adds. Technological advances Richard Shaw, Associate at Head Interiors, says that the development of CAD technology over recent years as a design tool has made it possible for interior designers and architects to sell and present their ideas and designs to their clients in a very realistic three dimensional format. It allows the client to be more interactive from the outset of the design phase to adapt and change as the project develops” says Shaw before listing advances in wallpaper, tile designs and LED lighting technologies as some of the most interesting changes in the industry. Walls & Roofs would like to give thanks and acknowledgement to Nimrod Design, Ergosystem, .able and Barrisol for the information they contributed for this article.

installation also offers additional benefits. “Using the quick installation method of gypsum board is the best solution considering its versatility, durability, economy and unique fire-retardant properties. Plus, boards can be easily installed by gypsum specialist contractors, reducing the number of contractors and building specialists necessary on site,” says Van der Nest. Insulation considerations Van der Nest explains that the quality of insulation is also an important consideration for residential development projects. Similar to other earthen material like facebrick and concrete, gypsum as a stand-alone thermal insulation material can be further enhanced using insulation to achieve a desired result. “The problem is that most insulation materials are highly flammable. Unlike traditional materials, gypsum is an excellent fire barrier protecting the insulation material. In order to prevent fire from reaching the combustible housing material and engulfing the entire home in flames, the board sacrifices itself, fighting the flames with its non-combustible core construction,” comments Van der Nest.
“A normal partition board may perform long enough, but having that extra bit of safety knowing that, if a fire does occur in one’s building, the occupants may be protected for an additional two hours with a Lafarge firecheck board is priceless.” Effective fire resistance has long been an important consideration in the construction of townhouses, flats and condominiums. Considering Lafarge Firecheck board’s fire rating of 60-120 minutes, it is an ideal solution for contractors and residential developers when planning or building homes. Gypsum board’s core, which contains fibre and exfoliated vermiculite that has high resistance to combustion, is what allows the product to achieve this fire rating. Gypsum board’s ease of installation, efficiency and cost-effectiveness has made it the ideal choice for builders and developers. Weighing less than traditional building materials, gypsum boards also eliminate the need for costly foundations. Van der Nest explains that, for contractors and developers on tight deadlines, the product’s quick

Preventing and containing fire In multi-unit developments, the threat of fire spreading from one unit to the next is a major consideration in preserving property and lives.

No sealer coat or bonding coat is required on plasterboard before plastering, giving contractorsaquickandeasywaytocompleteconstructions.
Suggestions to contractors: 1. Apply a softer mix of Lafarge Jumbo Multi-Purpose Compound 2. Work in smaller areas 3. Wet the surface to be plastered 4. Polish and smooth as required 5. Refer to instructions on packaging Steps for applying the compound to brick surfaces • Ensure surface is clean and free from dust • Apply Lafarge Jumbo Multi-Purpose Compound • Polish and smooth as required • Refer to instructions on packaging Lafarge gives these tips when applying the multi-purpose compound to plasterboard ceilings and walls: • No sealer coat or bonding coat required on plasterboard before plastering • Tape all plasterboard joints with “Fiba Tape” • Apply Lafarge Jumbo Multi-Purpose Compound to joints • Apply Lafarge Jumbo Multi-Purpose Compound to plasterboard surface • Recommended plaster thickness 3mm • Do not mix more than can be used in 90 minutes • Polish and smooth as required • Refer to instructions on packaging Quicker drying solutions Lafarge recommends a maximum of 3mm application when applying the Jumbo Multi-Purpose Compound to cement-rendered surfaces. If, however, the cement-rendered walls are new (and not fully cured) the mix should be softer and contractors are advised to work in areas of maximum 15m². When applying the Jumbo Multi-Purpose Compound to brick surfaces, a maximum of 13mm application is recommended. Due to the newly applied cement render water absorption properties, water is absorbed from the compound which results in quicker drying.

Steps for applying the compound to painted surfaces • Recommended maximum 3 mm application • If water-based paints were used, apply “Plaster Key” to painted surface, allow to dry and then apply Lafarge Jumbo Multi-Purpose Compound • If oil-based paints were used, apply bonding liquid to painted surface, allow to dry and apply the compound. Lafarge Jumbo Multi-Purpose Compound should not be mixed with any other plaster or compound and contractors must ensure that it does not come into contact with water that has been in contact with any other plaster or compound. If the compound is plastered over any other applied plaster, contractors must ensure that the surface has been: - Sealed with a suitable sealer - If unpainted, seal surface with “Plaster Key” - If painted with water-based paint, seal with “Plaster Key” - If painted with oil-based paint, seal with “Bonding Liquid” Precautions when applying to painted surfaces When applying the Lafarge Jumbo Multi-Purpose Compound to newly plastered ceilings or walls that are painted, contractors should wait a minimum of 24 hours to ensure the surfaces are completely dry. If the walls or ceilings were painted with water-based (PVA) paints, a sealer coat is not necessary (Lafarge recommends that the first coat be watered down 10% before the final coat is applied). A sealer coat is required when oil-based (solvent-borne) paints are used.

makes a charitable contribution LeadingpaintsupplierVersusPaintrecentlydonatedpaint for a daycare centre and two foster housing facilities in Mmakuanyane. The charity, called SA Cares for Life, is an NGOwithgreatpassiontochangethedestinyofchildren’s lives in South Africa. “We were in need of paint for two of our projects in Mmakuanyane – the Early Learning Centre as well as the foster homes. Our Early Learning Centre needed paint in order to maintain an uplifting and colourful environment for the toddlers,” says Elmien Claassens, Chief Executive Officer of SA Cares for Life. “Upon hearing about our charity and needed services, Walls & Roofs magazine contacted Versus Paints to find out if they would be willing supply paint for these projects. Versus Paints donated enough paint for two of our projects,” said Claassens. The Early Learning Centre provides educational stimulation and preparation for formal schooling. Children attending the centre also receive two nutritious meals per day. Most of the children attending are AIDS orphans or from very poor households, unable to pay for the day care. Claassens explains that the NGO and the paint suppliers also engaged with the community and received input from the parents when repainting the foster homes. “Versus Paint helped us to repaint the exterior of the foster homes, but we are giving the foster parents an opportunity to finish off the interior painting jobs themselves. Painting is a wonderful way for our foster mothers to make the house more homely,” explains Claassens. The foster care project at SA Cares for Life entails finding alternative living solutions for children who are orphaned. “Foster homes are a great family-based care solution to parentless children. Our vision is to
continue building homes over the next few years in this area and even more across the country,” says Claassens. “We would like to thank Versus Paint for their contribution towards our projects. There is so much that can be done and many lives can be improved from donations such as this,” adds Claassens. Marlene van Rooyen, editor of Walls & Roofs, which is part of the Media in Africa bouquet of niche magazines, says that the company was glad to be a part of the project. “We are familiar with Versus Paints and we are grateful that their team offered to help this charity,” comments van Rooyen. Versus Paint was established in 2000 and they are renowned for their high- quality products that are easy to apply. Although the products originated in Europe, they are now manufactured locally. Versus Paint has formulated materials that are environmentally friendly and beautifully textured. Versus are also one of the first companies in South Africa to sell paint online, keeping them innovative and on the forefront of providing a convenient service for their clients.

Why use gypsum
in refurbishment projects? Atsometimeoranother,homeownerswillbeconfrontedwiththedecisiontoeitherpurchaseanewhouseorimplementhome improvementstotheexistinghome.Althoughresidentialhousingstructuresarebuilttolastalifetime,thisisnotalwaysthecase with the families that occupy these buildings.
Though relatively new to the South African market, gypsum boards have been widely used for years in the UK and USA. Van der Nest comments that although the local building market’s knowledge of gypsum has been relatively limited to the commercial building sector, its usage is growing and many people are now embracing this revolutionary technique in their home. Concerned about lightweight products? Another reason for its popularity is its weight in comparison to other materials. Many homeowners, while considering its sturdiness and insulation qualities, may be concerned with using a lightweight product like gypsum in place of traditional methods. However, gypsum boards are rigid with the ability to withstand intense impact and puncture or any other damage. Many household bathrooms reveal tiled walls and mould on the ceilings. Fitting these areas with gypsum moisture-resistant boards avoids stains and sagging.
“Families grow and with them the need to expand or reconfigure a home is necessary,” says Shane van der Nest, Marketing and Export Manager of Lafarge Gypsum. “A room today might need to be a study tomorrow, and a lounge the next day. So, by using a gypsum product, you are not restricted by the current layout you are living in today. As families grow or shrink through time, homeowners have added flexibility when designing their interiors using gypsum.” According to Van der Nest, reconfiguring a home’s layout with gypsum boards is the ideal solution considering the material’s properties, cost and ease of installation. Gypsum is a well-known product in the building industry due to its versatile application, moisture resistance and fireretardant features (the boards are non-combustible, having a fire-rating of 60 to 120 minutes). Internal remodelling Gypsum boards can be used to expand a room to start a home business, build a baby’s room or achieve that one-of-a-kind entertainment centre. This material can also be used throughout a home’s internal layout in kitchens or as walls and ceilings, for example when the need to remodel arises. “Internal remodelling can be a daunting task, but use of premier gypsum-based boards eases the process and takes the difficulty out – bringing in fun and creativity. With its quick installation and malleability, gypsum boards can be customised to conform to almost any purpose, satisfying many styles for the truly creative homeowner,” explains Van der Nest.

with additives for increased fire and moisture resistance are ideal. Ceramic tiles can also be fitted onto moisture resistant gypsum boards adding that personal touch to your home,” says Van der Nest. Gypsum walled and insulated rooms allow for excellent temperature control during the winter or summer months. The boards’ thermal insulating properties prevent undesired heat gain or loss, maintaining a comfortable environment and reducing the owner’s energy demand. “Homeowners experience cost savings on electricity, through the substantial drop in consumption via the air-conditioning and heaters when using gypsum products. Now, more than ever, is a good time for homeowners to embrace innovative building techniques through gypsum products,” concludes Van der Nest.

According to non-profit independent trust FinMark Trust, which is primarily funded by the UK’s Department for International Development, South Africa’s affordable housing backlog is approximately the same size backlog it estimated as having had in 1994 (www.finmark.org.za). FinMark Trust says that although the housing budget for the 2008/09 financial year had been used and even exceeded, the delivery rate of 250 000 units was not reached and it will not be possible to address the backlog by 2014. “While the backlog may be addressed by 2020, as per our Millennium Development Goals commitment, this does not take into account population growth, which suggests that informal settlements will persist for much longer,” reads the report. “The problem is that each year there are more 18-year-olds that

qualify for affordable housing and if you fall behind, a snowball effect is created,” says Adele de Lange, human settlements specialist at the Cement and Concrete Institute. “Building affordable, quality housing at a high speed is of utmost importance.” Luthando Vutula, Managing Executive for Absa Home Loans, says the industry needs to construct at least 200 000 units per annum to reduce the backlog by 60% and that certain areas have been prioritised by government to reach this goal. “The four areas are intended to meet our country’s housing objective: accelerated delivery of housing opportunities; access to basic services; more efficient land utilisation and an improved property market,” adds Vutula. Challenges for new developments According to Vutula, some of the challenges facing developers in the low-cost housing market include issues such as: • The cost and availability of well-located and suitable land. • The protracted nature of local government processes for releasing and preparing land for housing development. • Access to adequate bulk infrastructure and other related services in

Carollize Laing, head of Residential and Affordable Housing at First National Bank(FNB) Commercial Banking, agrees that the cost of developable land (which starts with the price paid for raw land and then escalates with the cost of obtaining the required planning approval) is indeed one of the biggest challenges for developers. “The cost of land is a critical success factor – if the land cost is inflated, the project will not be feasible since building costs are fairly fixed and very little room exists to manoeuvre selling prices in this market segment,” says Laing. “In addition, the availability of bulk infrastructure (especially electricity) remains a concern and increases the cost of development dramatically as developers often have to come up with the required funds to install bulk infrastructure which ideally should be supplied by the relevant local authority.” Getting access to funding for affordable housing developments has also been highlighted as one of the key challenges in the industry. “Many developers have complete plans in place; they are just waiting for the go-ahead from Government to start building. Unlocking the funds for affordable housing projects seems to be a prevailing problem,” says De Lange. Jeremy Gibberd, who does research for the Built Environment unit at the Council for Scientific and Industrial Research (CSIR), says that there are different funding streams available for developers interested in affordable housing projects. “Funding is available from commercial banks, but lower rates may be possible if developers can work with Municipalities to access finance from Development Finance Institutions (DFIs). There is also increasing finance available for energy efficient and renewable technologies particularly, if this is being implemented at a large-scale,” says Gibberd before explaining how access to land also presents difficulties for developers. Laing comments that when banks make project finance available to developers, they accept the associated risks but also take comfort in the demand for the proposed product and thus expect this demand to mature into confirmed sales with bond approvals. “Since most consumers experienced a certain level of financial distress over the past 24-30 months, which resulted in adverse credit records, obtaining bond approvals from financial institutions remains challenging. This does, however, open another opportunity for residential property – rental stock, which offers many consumers an alternative to home ownership. Many developers are capitalising on this opportunity, although it may require an increased level of equity from the developer,” says Laing. Gibberd explains that the distance that residents in these areas have to travel for work also creates significant problems. “Affordable housing can be located far from services, work and public transport, where land is more readily available and cheaper’. says Gibberd. “This results in transport costs being a significant proportion of household income for many families. This money would be better spent on education, health and other needs”. Llewellyn van Wyk, CSIR Built Environment principal researcher, says there are also capacity constraints within the Government itself. “Sometimes there just aren’t enough hands on deck and municipalities often lack the expertise to evaluate tenders,” says Van Wyk. “There are lots of opportunities in this market, but there are also a lot of challenges that developers need to overcome,” says Van Wyk before listing delivery from tenders, the evaluation process and getting the bulk services to site as possible problems. “Each of these challenges presents an opportunity to lose money,” adds Van Wyk.

The current backlog in the affordable housing sector is approximately 2,1-million units. A staggering R44-billion has been set aside for housing projects over the next four years.
Alternative financial models According to FinMark Trust, it is neither sustainable nor desirable for Government to finance the housing needs of South Africans on its own. “Policy must provide for participation by both the private sector and individual households in the financing of their housing,” says the Trust. In 2010, R16-billion was allocated to building new houses for the poor. In his budget speech, Sexwale explained that this money would go to the “poorest of the poor” who earn less than R3 500 a month. “The prerequisites in order to qualify for a low-cost home left a huge gap in the residential market consisting of individuals that earn an income that is too low to qualify for a normal mortgage from the bank and too high to qualify for Government housing,” says De Lange. “Alternative financial models have now been developed to ensure affordability for all role players,” says De Lange before explaining that the market has been expanded from earlier government-only subsidised housing to include credit-linked houses and open-market bonded houses through the creation of a government-funded guarantee fund. Laing, says that the backlog for this gap market is estimated at 630 000 bonded units. “Besides the backlog of 2 million fully subsidised homes, there is still a significant gap for the income group that earn between R3 500 and R15 000, which is where FNB can participate meaningfully through the provision of bridging finance,” says Laing. “Our commitment stretches across the entire value chain which Vol 11.6 | September 2010

ultimately results in FNB making a difference in targeted communities through the provision of housing.” In his budget speech, Sexwale said that this fund currently has a dedicated R1-billion for the so-called “gap market”. He explained that nurses, teachers, police, Government officials and blue-collar workers would be the ones that benefited from this fund. De Lange believes that innovative public and private sector partnership is one of the key drivers to making the low-cost housing market an affordable initiative. “Once the private sector is involved, the financial model starts to work because there is money to be made and the endeavour is mutually beneficial,” says De Lange.
“Developers get approximately R40 000 per house. With the small amount of money available per unit, companies need to get a large contract so that economies of scale make the project financially viable,” says De Lange.
means that we assist developers with project finance via FNB Commercial Property Finance and furthermore extend our involvement over the longer term by financing the end-users via FNB Housing finance,” says Laing. “The close alignment between the two business units makes it possible for FNB to provide an end-to-end service to an affordable housing developer, thereby enabling the developer to obtain development finance and at the same time secure a take-out for his stock. This
How financially viable is this sector? De Lange says the housing backlog and required infrastructure for these developments have created an ideal opportunity for the construction sector. “Developers get approximately R40 000 per house. With the small amount of money available per unit, companies need to get a large contract so that economies of scale make the project financially viable,” says De Lange. Carollize Laing says that the economic slowdown of the past two years, however, has influenced the level of involvement from developers in this market. “Developers are cash-strapped as profits are caught up in vacant land holdings – which were more often than not acquired at inflated prices – and remaining stock. Developers therefore find it extremely difficult to come up with the required equity contribution to secure project finance from banks,” says Laing. A report by FinMark Trust, entitled “Framing a Finance Strategy for the Human Settlements Department”, in November 2009 said that the Department’s financing framework, in terms of subsidies, credit, Development Finance Institutions, etc., needs to be revised in order to address the challenge of scale, affordability and sustainability (www.finmark.org.za).

Modern concepts of social housing at Cersaie Social housing has a long history in Italy and two meetings on this theme will be organised at the international ceramic tile exhibition, Cersaie. Internationally acclaimed sociologists and housing professionals will be speaking at conferences entitled “Building, dwelling, thinking”. According to the organising committee, the key aspect today is not just to provide housing to people from economically underprivileged segments of the population but to offer a diversified response to demand from all strata of society, a trend that is inextricably linked to broader transformations involving lifestyles and, by analogy, urban areas. “Whole neighbourhoods are changing, new citizens – whether we like it or not – are becoming part of the urban fabric and bringing their own new and indelible mark. New buildings and neighbourhoods are springing up, while old houses and often even whole city centres are being transformed to keep pace with the lifestyles of the inhabitants. Changeable by definition, the city is not just a collection of houses but also the place where there are common spaces, the spaces of sociability, another mainstay of the modern concept of social housing,” says Andrea Serri from the Cersaie Press Office. The conferences will take place on 29 September and the meeting will feature a debate between the high density approach of the Dutch firm Mvrdv – represented by architect Natalie De Vries – and the Italian architect Cino Zucchi, who prefers a medium-low density housing concept. Professor Fulvio Irace, architect and professor at Polidesign, the Milan Polytechnic Consortium set up for the purpose of providing innovative solutions in terms of projects and proposals in a constantly evolving technological, productive and professional context, will act as moderator and provide a further contribution to the debate.
In May, black-empowered and JSE-listed housing developer Calgro M3 reported an almost sevenfold increase in headline earnings, with group revenue for the year increasing by 155% to R317-million compared with R124-million the previous year. The company said that prospects for the company were “extremely exciting” given the shortage of housing in the country. Gibberd says that more and more developers are realising the opportunities in this sector. “In the past, large developers that are renowned for upmarket commercial developments didn’t want to get involved in the low-cost housing sector due to perceptions about risks and profit margins. However a number of these have now done projects and been pleased with the results,” says Gibberd. Absa has held two successful International Innovative Housing and Sustainable Energy Efficiency Competitions; initially at the Eric Molobi Innovation Hub in 2006 and then in Mbekweni area outside the City of Paarl in the Western Cape in 2009. Various innovative and alternative materials were showcased targeting the BNG subsidy, low cost and affordable housing markets. Conventional construction systems and materials were excluded from the Western Cape competition. Despite these exclusions, seventeen different technologies were successfully erected as part of the innovation competition. Absa continues to consider the financing of various alternative building methods and products in terms of its alternative building technology policy. The policy provides guidelines and criteria for the evaluation of new building systems and associated materials. The policy also focuses on quality assurance, product certification (as a confirmation of the building system’s suitability for local climatic conditions), its cost effectiveness and its ability to be implemented faster and efficiently. Absa further assesses the social and end-user acceptance of such housing technologies, as well as its compliance to Sans 204 and other energy efficiency requirements Although some of these systems are being used in the affordable housing market, Gibberd warns that some of these technologies may not be appropriate for South Africa. “A few companies have proposed imported systems that need to be evaluated carefully before being implemented, in particular consideration should be given to local content, affordability, maintenance and thermal performance both in terms of thermal mass and insulation,” says Gibberd. “The thermal mass properties inherent to concrete block and mortar construction is ideally suited for the South African climate”, De Lange remarked. “Further to that, basic cement and concrete construction techniques are historically familiar technologies even in the remotest rural parts of our country. Coupled with stringent quality control, it remains a sustainable cost-effective and fast track solution with a proven track record of social acceptance and bondability.” Van Wyk warns that complete projects need to be taken into conContinues on page 46

Continued from page 44 On 16 August, Director General Chabane Zulu said that the Department of Human Settlements were continuing to investigate the 10 246 housing projects and that a shortlist of 20 projects are “problematic”. These projects are worth R2-billion and the average contract is approximately R100-million per contract. Investigations of corruption in the affordable housing market started in 2007 and since then, R44-million has been recovered and R11-million has been paid back to the state. sideration when tendering for Government contracts in the affordable housing market. “The technical documentation for these houses is weak and it doesn’t include a bill of quantities. People think that they are designing a 40m2 house, but this isn’t really the case – you need to work out the varying foundation requirements for houses on different levels to determine if a step or stairs will be needed, for example, and you need to bill for these requirements. You also have to design for the total package to provide for the sewerage system and infrastructure,” says Van Wyk. Green and affordable: material savings A pilot project following research by the CSIR is seeing the first 60 of 411 greener, affordable homes being constructed at Kleinmond in the Western Cape. The project is being funded by the Department of Science and Technology (DST) and the Overstrand municipality has come on board to implement the innovative technologies of the CSIR. Each house is approximately 40m2 and has two bedrooms, a combined kitchen, dining and living area, a shower and a toilet. “We focused our research on using standard building materials for standard houses that are being rolled out by the Department of Human Settlements and
identified where there are opportunities to improve performance with the least cost increase,” says Van Wyk. “We analysed the subsctructure, superstructure, roof assembly, finishes and services. During our research we pulled each section apart to see where less material could be used and what could be added to improve the comfort levels within these homes,” says Van Wyk. A new floor slab technology, which was developed by the CSIR, was used for the house. “This floor technology is only 50mm thick and removed excavation from our building process, which saved us a lump of money that could be used for other things in the house. Using modular masonry construction also saved us a lot of time and the team, which would normally take 2 days to build the wall of a house, now only needed one day per house,” says Van Wyk. Van Wyk’s team was also able to save approximately a ton of concrete on each house, which led to a reduction of 700 kg of CO2 emissions. The roofs of these houses are also tilted so that the water spills over the ridges into a rainwater tank. Lambdaboard, a flexible-faced Polyisocyanurate insulation board, was used as a ceiling board due to its low coefficient of thermal conductivity, and the walls were plastered Continues on page 48

Over 100 houses have been built with aesthetic clay bricks at an affordable housing development in Khayelitsha.
There are many self-build projects in the affordable housing sector, which encourage community participation from local residents.

According to Van Wyk, affordable housing needs to focus on correct designs that will use the least amount of energy to heat or cool the space and require the least amount of artificial lighting. “Orientation, for example, is a huge contributor to the comfort levels within living environments,” says Van Wyk. Corruption in low-cost housing The booming affordable housing market is not without its corruption cases. Five lawyers have been struck off the roll, 1 570 officials have been arrested (1 189 of whom were convicted) and R38-million has been recovered. The Department of Human Settlements is concluding its investigation into abuse of the Low Income Housing Subsidy scheme. At the 2010 South African Property Owners Association (SAPOA) Awards ceremony, Dr Mamphela Ramphele, chairperson for the Masakh’ iSizwe Centre of Excellence at the Department of Transport and Public Works in the Western Cape, said the RDP model for housing conflicts with African culture. “The RDP housing delivery is not an appropriate model. In African culture, a boy is defined as a man when he builds his own house. We cannot treat people like children when it is in their culture to be a part of the building process,” Ramphele told the audience. Gibberd agrees that there are problems with supplying millions of people with the same 40m2 house. “There are opportunities to diversify the type of housing built and the way this is delivered. In particular, there are opportunities for self-build projects which can result in good quality, affordable housing and help build local pride and social cohesion” says Gibberd ”I have even seen this in places like London, where we did 4 to 36 unit developments at low cost with totally unskilled owners. I think the need is being recognized by the Department of Human Settlements who have increased the range of ways housing is being delivered”. De Lange says that Cosmo City, a mixed development that includes low-cost housing, affordable housing and upmarket homes, is one of

the country’s success stories in terms of new developments. “There were many community initiatives where people were trained and input from residents was received. The area has parks, a nursery, public play areas, and more,” says De Lange. “In South Africa’s affordable housing sector there are success stories and horror stories. We’ve seen RDP houses that are falling apart due to bad building practices and this type of accommodation could also be leading to residents not realizing the true value of their new homes,” says De Lange before adding that there have also been cases of fraudulent behavior by homeowners. “A person will get a subsidised home, which cost more than R40 000, and sell it for less than R10 000, for example, and then try to get back on the municipal waiting list for another home. Some homeowners are also sub-letting their homes for a profit. Laws have now been put into place to prevent this type of behaviour,” says De Lange. Planning for the future Gibberd concludes that in order to address the backlog in a sustainable way, one mustn’t only focus on the number of houses that need to be built but also on ensuring that housing is sustainable and will be appropriate, including being in the right place, for at least the next 50 years. “One cannot solely focus on numbers of houses” says Gibberd ”If one broadens the approach to include where, and how, employment and small businesses is being created, or can be created, and ensuring that there are is local access to services, one can build more sustainable and integrated developments. If people have local work and access to services such as education, recreation, health facilities, less time and money is spent on transport. This makes more money available for local housing and helps to reduce the reliance on government for this. This integrated development concept is included in the Sustainable Development Criteria for Built Environment project we have undertaken”.

How flexible is SANS 204? Withnew building regulations and SANS10-400XA, that areset to change theway buildingsare designedand constructed, professionals need to be aware of the options available. Conrad Smith, general manager of Isofoam, manufacturers and distributors of IsoBoard, tellsWalls & Roofs that professionals aren’t only tied down to the more prescriptive requirements of SANS 204 in order to successfully adhere to the regulations, but that one should understand the flexibility and scope for innovation, in order to meet energy efficiency requirements in the most cost effective way. “SANS 204 has simple prescriptive requirements, but the prescriptive option is not the only way that one can comply with,” says Smith. “In some building designs, the prescriptive requirements could lead to a higher specification of a product than needed. This could be true of insulation requirements in different climatic zones. The result of this would lead to a less than cost effective solution and professionals need to know what alternative routes to compliance allow them to legally meet the new requirements in the industry.” Background As most design professionals are aware, National Building Regulation X is intended to build sustainability into South African building construction. Part XA is the corresponding part of the Building code that deals with energy efficiency. The first edition of this part is due to be published before the end of the year. The new National Building Regulations will be met by complying with SANS 10-400XA. SANS 10-400 XA contains the energy efficiency performance requirements for many building types and refers to SANS 204: Energy Efficiency in buildings for the prescriptive provisions. Furthermore SANS 10-400 XA also allows for the Competent Person to design and build according to a rational design. “Building professionals should not just look at a single element of prescriptions in the regulatory requirements, but rather look at the building in total,” says Smith before explaining that professionals will be faced with three options once the standard is passed: “You will either need a suitably qualified and experienced professional to perform calculations or a computer modelling of the theoretical electrical energy usage and demand for the proposed building to ensure that you adhere to the requirements outlined in the tables in the standard, or alternatively the architect, engineering professionals and contractors will need to ensure that the prescriptive requirements of SANS 204 are met. The third compliance route is to make use of the reference building method, which also uses computer modelling by a qualified person, to show equal energy performance of that same building as if the prescriptive requirements had been applied ,” says Smith. Avoid unnecessary expenses Some potential for flexibility and innovation is built into the SANS 204 standard by the introduction of the reference building concept and method. “Many people have realised that the roof and or ceiling

This section allows for the professional to avoid the prescriptive levels and rather use other cost effective, innovative building solutions and designs that will give the same comfort levels and require the same amount of energy,” explains Smith. The reference building method is where a competent person computer models the energy usage and demand of the proposed designed building and the energy usage and demand of the building as if it were built using the SANS 10400-XA prescriptive interventions. The energy usage and demand of the new design should be equal or better than the reference building (SANS 10400-XA prescribes). Premium thermal insulation IsoBoard, an extruded polystyrene rigid foam thermal insulation, will help architects and building owners achieve compliance with the regulations and the required results in terms of comfort and energy efficiency, with the right amount of insulation.

effective building solutions under the reference building method of SANS 204, than would be the case if the prescriptive R-value or thermal resistance tables were applied. The versatile thermal insulation works by providing a barrier to heat transfer from one side to the other. “Insulation does not, by itself, provide heating or cooling, but rather regulates where comfort should be - inside of buildings,” says Smith. “One of the best ways to conserve energy and improve comfort is to provide high class insulation for buildings. IsoBoard Insulation has Agrément Board certification for four applications and this certifies that the product is fit for use in the applications we recommend,” says Smith. IsoBoard can be used in ceilings, in cavity walls, inverted roofs, over purlin insulation as well as either below the screed above the floor slab, or below the floor slab in surface bed insulation applications. The board is also extremely durable and comes with a 10 year guarantee. “The product can last the life of the building if installed as per company specifications, isn’t exposed to the sun and be painted with water based paints when used in exposed applications.

Energy efficient technologies for affordablehomes The Saint-Gobain Construction Products’ HumaneHome collaborationoffersanenergyefficient,affordablesolutionfor a segment of the market that has yet to become aware of the implicationsofimpendingchangestothebuildingcodethat affect the energy efficiency of built structures.
Lightweight products and insulation help to create affordable homes that are energy efficient and quick to build.
into a beautifully finished home, the likes of which they would not have been able to afford otherwise.” Apart from finishes such as tiling and ceilings, to which this segment of the market is not accustomed, the homes include a number of interventions that will reduce the home owners’ energy costs. “The homes are fully insulated, and do not need heating in winter or cooling in summer,” says Senamile. “They are fitted with a solar water heater, and are also equipped with a rainwater harvesting system, to be used for irrigation for a home vegetable garden.”
Something else to consider is that the labour and material costs associated with traditional methods of construction have a significant impact on the affordability of new home construction. Typical homes are seldom properly insulated, adding a further cost burden to the home owner once the home is complete.
Finance is within reach Saint-Gobain, HumaneHomes and retail champion Cashbuild are working with local financial institutions to create special mortgage products for potential home owners. “We are adopting a holistic approach, so that we can offer a full housing solution – from the creation of a personalised home environment to its construction, with a prepared introduction to mortgaging institutions,” she concludes. For more information about HumaneHomes, contact John Fleming on +27 (0)11 786 0296 or +27 (0)82 880 1610.
Record energy efficiency in record time However, the team at Saint-Gobain Construction Products has partnered with a local architect to create a green home built from the company’s lightweight building materials. Known as the ‘HumaneHome’, it offers the combined benefits of energy efficiency and short construction times. It can cost as little as R185 000 (excluding the cost of land) to build an energy efficient two bedroom house with a living area, tiled kitchen and bathroom. This includes all electrical and plumbing fittings and top-end finishes from ‘E-range’ glazed aluminium windows to a 2500lt rainwater harvesting system. “Potential home buyers can choose their design and finishes. The home is then manufactured off site and supplied in flat-pack format, in as few as 28 panels,” says Senamile Mazibuko, manager of social housing at Saint-Gobain. “The concrete slab is thrown on the home owner’s land, and we start erecting within days.

1000 houses in Rustenburg get lightweight roofs
VelaSteelBuildingSystems(Vela),atrustedlightweightsteelsupplierinSouthAfrica,recentlysuppliedover1000affordable houses in Rustenburg with roof trusses.The format in which the trusses were supplied, along with the speed of erection and new design features, contributed to the success of this project. Vela started supplying the lightweight UTRUSS roof trusses to Foxway, the contractor, in May 2009 and the project was completed in April 2010. “The roof trusses were supplied in a flat-pack format and assembled on site, which saved a significant amount of time and cost,” says Brent Harris, the Managing Director of Vela. The company trained up local labour and contactors to assemble and erect the trusses which attributed to skills development on site. Vela provided continual support and assistance so that the project could be completed within a short amount of time. Aesthetic solutions The lightweight steel roof trusses which Vela supplied to the affordable housing development in Rustenburg are easier to handle and quicker to erect than conventional timber trusses. “The houses varied in size from – 50m2 to 60m2. What makes our lightweight galvanized steel roofing solution unique is that the trusses have timber sprockets fitted into them to comply with local aesthetic requirements ,” says Harris. Harris explains that a number of factors such as cost, speed of delivery and construction were taken into account by the client in choosing Vela’s roofing solution. “Vela’s design and manufacturing process allow us to create a custom solution for each project we are involved in. The weight reduction and ease of installation have led us to become a preferred supplier for projects in the low cost and affordable housing sectors,” concludes Harris.
The roof truss supplier trained local labourers to assemble the trusses on site to fast-track the project.

housing solutions Ama BrickBrick, major manufacturers of cement stock bricks and maxi stock bricks, have been in business for the last five years. The company recently supplied over 400 000 bricks for RDP developments in Tembisa and Soshanguve in Gauteng. “We supplied 250 000 maxi stock bricks for affordable housing in Tembisa and 150 000 for a similar project in Soshanguve. We also provided 20 000 of these bricks for a primary school in Diepsloot, free of charge, as part of the company’s social responsibility initiative,” said Derik van der Watt, director of Ama BrickBrick. “Our maxi stock bricks are two-and-a-half times larger than normal bricks, making them the ideal solution for affordable housing developments that have to build within a short amount of time.”
Ama BrickBrick’s team consists of 45 people at the Diepsloot manufacturing facility and 3 delivery trucks.
Ama BrickBrick’s manufacturing facility is based near Diepsloot on the N14 in Gauteng and they deliver bricks within a radius of 100 km. “We manufacture up to 2,5-million bricks per month and we deliver everywhere in Gauteng as well as large parts of the Limpopo area,” comments Van der Watt. Van der Watt explains that Ama BrickBrick’s products offer high-quality, durable building solutions and are available at competitive prices. “Our cement bricks do not contain ash, but their prices are competitive with a variety of other materials used in the market place, like clay bricks and ash bricks. Although our bricks are mainly used in plastered buildings, they can also be used as face bricks,” says Van der Watt. Ama BrickBrick’s team consists of 45 people at the Diepsloot manufacturing facility and 3 delivery trucks. One of the advantages of partnering with Ama BrickBrick is the fact that no labour is involved on the client’s site. “We have the necessary labour force and equipment to deliver the materials and offload on site. Customer service and good quality products are what have helped Ama BrickBrick thrive and continue to grow throughout the recent economic recession,” concludes Van der Watt.

Below: Corobrik’s economic face bricks were used to build Khayelitsha’s first double storey unit currently being used for a crèche, after investigations by the South African Homeless People’s Federation found Corobrik to be the most sustainable, durable and economical product for affordable homes.
Clay bricks for 110 Khayelitshahomes HavinglivedinKhayelitshatheirwholelives,withinformalhousingbeingtheironlyoption–localresidentswereecstaticwhen plans for formal housing came to pass. Clay face bricks from Corobrik – reputed for superior quality bricks – were among the building materials used in this project. “This was a rewarding experience for us having dealt directly with most residents. Many, though in their fifties, have never lived in a formal house before,” said Christie van Niekerk, Manager Corobrik Western Cape. Corobrik gave local government a competitive proposal for their economic face bricks, which was immediately accepted for subsidising. To date one hundred and ten 40 m² and 72 m² houses have been built and the aesthetic appeal of the face bricks is obvious. Finding alternate building solutions According to Van Niekerk, the Homeless People’s Federation of South Africa became aware of the poor quality of the new houses, which prompted them to start investigating alternate building solutions in this area. Although budget was a key factor, the Federation was looking for a strong, sturdy, maintenance-free product.

“Fire disasters in such rural areas are common; therefore the fire-resistant nature of Corobrik’s clay face bricks was an impressive quality for the Federation. Thermal efficiency was yet another significant necessity. Keeping warm during the cold winter months with no electricity is a reality for most residents and brick walls made a positive improvement in this area,” said Van Niekerk, before adding that the high thermal mass of Corobrik’s clay bricks works particularly well in winter to moderate internal temperatures. “Houses built using double-skin clay brick construction, incorporating ceilings with insulation and adequate roof overhangs present the most cost-effective, durable and sustainable solution for the development of low-cost housing on a national scale,” said Van Niekerk. Footing the bill Patricia Matolengwe, Director of the Homeless People’s Federation, explained how financing of the project works when specifying such large projects. “Representing people from poor backgrounds, our main concern was the cost. While the municipality subsidised part of the cost, it is up to residents to settle the remaining expenses. We know Corobrik’s reputation as market leaders and were afraid that affordability would be a problem. After just one meeting with Corobrik we realised that our fears were unfounded,” said Matolengwe. “These bricks will never need maintenance so the people won’t have to worry about expenses relating to painting/ plastering in future. Also, the bricks are strong,so residents can sleep at night knowing that rain will not seep into or damage their new homes in any manner. Corobrik’s quality and service is outstanding but most impressive has been their contribution to the lives of the poor,” concluded Matolengwe.

Glass & Pe r for m a nce G l a z i n g
Glass strength, regulations and technological advances Architects, developers and designers have been using glass as a building construction solution material for many years. Technological advances have made it possible to create high-performance glass façade systems that offer different qualities and features to curtain walls of 100 years ago. From fire resistance to vertical glazing, strength considerations and complex architectural designs, Walls & Roofs finds out what challenges and innovations are available in the glass and performance glazing industry.
Glass and sustainability Nick Wright, President of the South African Glass Institute, gave a presentation on the trends and regulations for glass installation at the Façade Design & Engineering conference which was held in Johannesburg in August. “One of the biggest problems that professional designers have relates to new building codes and the issue of sustainability. We are not building sustainable buildings – we are building office blocks that create poor working conditions not suitable for office productivity and we need to start focusing on building comfortable environments suitable for all of the office’s workers,” says Wright. Wright explains that the cost of making a building more sustainable isn’t necessarily a great expense, but the impact it has on the bottom line is causing design professionals to continue with bad building practices. “It costs approximately 6% of the price of a R100-million building to make it more sustainable, but incorporating this added cost into the price of the project would almost certainly mean that developers

would not get the return on investment that they anticipated,” says Wright. “Another problem is that the person who owns an office park, for example, isn’t necessarily paying for the electricity. The owner would be spending more on energy efficient building practices without actually feeling the financial benefits of these practices, there is no benefit only cost.” says Wright. Transparent Strength When choosing the glass used for a project, SANS 10400 the application of the National Building Regulations Part N – Glazing applies. According to this standard: The thickness of panes of glass and flat solid polycarbonate sheeting, other than in lifts, shall be no less than given in tables 1 – 6, or it needs to be determined by a competent person (glazing) in accordance with the requirements of SANS 10137. “There are 7 key considerations when designing the glass for a project,” says Wright before explaining each point:
Glass & Per fo r m ance G lazing
“The amount of strength of toughened glass can vary. At the Murray & Roberts head office, a pane of glass broke and I analysed the glass to see why this happened. From the picture you can see the small particles of glass, indicating a good surface compression and a predictable design stress and load resistance of the glass. When determining the cause of failure , you can zoom in and see a crack pattern that looks like butterfly wings and that the irregularity, which caused the glass to break, is a tiny black particle in the centre of the wings where the butterfly’s body would be,” says Wright. “In the EU, there is a test for this type of architectural application. Every piece of glass is “Heat Soaked” - put into a furnace for controlled time aat set temperature to see if it will break, which will let the professionals know if it is safe to use on site. Should glass break,somebody could get hurt and people could be held liable,” says Wright.
Glass blocks at Maison Hermès in Tokyo, Japan, has lead the building to be called a “magic lantern.

Tempered or annealed Tempered glass is up to five times stronger than annealed glass and when this toughened glass is broken, it shatters into many small fragments which reduce major injuries (www.glassonweb. com). Tempered glass is more expensive than annealed glass due to the production process and annealed glass is still widely used because of its low cost.
Toughened glass can be ‘spider-fitted’ to safety glass on facades.
Left: Toughened glass with a special interlayer was used at Soccer City the venue of the FIFA World Cup Final. The glass was tested to ensure that the level of post-failure breakage was acceptable for the application.
Glass thickness “Thicker glass is stronger. To make it look thinner reduce the colour,using low iron glass” says Wright. “The sand needed to make this type of glass is not available locally so the glass is imported.”
Right: The large pieces of glass used at a house in the Southern Cape will cost approximately R10 000 per square metre.

Glass size Wright explains that smaller pieces of glass are generally stronger for the same thickness and if you want to build with bigger pieces of glass, you can expect a higher price tag.
Large glass sheets create a dramatic effect.

Usingphotovoltaics on a glass façade: Kollektivhuset One of PV-NORD’s demonstration projects shows the double function of incorporating solar cells into a building. At Kollektivhuset in Denmark, surplus heat from photovoltaics was used to create both a dynamic façade as well as provide greater comfort for the occupants of the building. The house is a concrete, 11-storey highrise that was constructed in the 1950s. A west-facing façade used to consist of open balconies until DOMUS Arkitekter A/S had been tasked with renovating the balconies and the development of design concerning the balconies which, by enlargement and glass covering, have been made more comfortable and approachable, allowing access to the wheel-chairs which many of the occupants use. Solar cells were placed in the new façade of glass and these cells can produce both heat and electricity. According to PV-NORD, the solar cells were designed in light of different parameters, for instance, the density, the visual expression from both in- and outside, and the light passing through. The coloured glass behind the solar panels provides an image of daily use of the balconies. PV Nord also explains that, passing the building often, one experiences how the vertical or horizontal elements of the façade become noticeable depending on the changing seasons of the light.

Above: The glass panes at a residential building in Hartbeespoort Dam will cost much less, but a different type of look is created due to smaller panes and the fixings that are required.
Glass loads The new building loads were recently published in SANS 10160 for cladding (windows), floors, roofs, walls, partitions and balustrades in May 2010. “Glass load calculations are very important for rational design of glass and everyone must design according to this, ,” says Wright. “The glass characteristics dictate that the longer the load the weaker glass. Floors and pool glazing are therefore very thick. The SANS 10400 Part N demed to satisfy only gives designs for vertical glazing and therefore every single roof-light needs to be signed off by a competent person. Sub-contractors aren’t doing this because they find the fees cannot be incorporated into the job because not all are towing the line.” says Wright. Glass support “Holes in glass may lead to added stress on the material. One should also ensure that there isn’t any glass-to-metal contact because this normally leads to breakage. The fewer supports, the thicker the glass should be, which also means that the price will go up,” says Wright. Left: Thicker glass is needed for frames with less supports, which leads to an increase in the price. The less holes in the glass, the stronger the glass will be.
Glass edge and surface condition According to Wright, poor edges reduce the strength of the glass and surface damage allows stress concentration on loading. “If the glass is scratched, the material is weakened. Sandblasting also weakens glass and one needs to prepare the edges of the glass to guarantee their strength,” adds Wright. Correct cleaning is therefore vital. Risks of Failure “One needs to take the likely behaviour of people into consideration when determining the post failure strength of the glass required for various applications,” says Wright. “Children behave differently to adults and the number of people and their activities in a certain area will also influence their actions.. Glass balustrades at airports need to be strong, high and in the correct places to ensure people’s safety. Glass failures could have deadly consequences and design professionals need to adhere to the regulations and do all the necessary tests to ensure the safety of the building occupants,” concludes Wright.

The colours, structural qualities and technological advances of glass blocks give design professionals more flexibility to create innovative constructions.
High resistance, fire retardant and bullet proof glass bricks have been used in many constructions around the world.
GlassblocksatMaisonHermèscreatesamagiclantern Seves glassblock, a business unit of the Seves Group, is a leading manufacturer of glass blocks for architectural and interior design applications. Owning 36% of the world’s glass block production and distribution market, the company is able to provide a variety of performance and aesthetic glass block solutions to the industry. “Magnificent projects have been created with glass blocks,” says Nicola Gaspari, Seves export manager for Africa, North America, the Middle East and selected Eastern European countries. Gaspari, who works at the company’s production facility in Italy, recently gave a presentation at Aluglass Bautech in Johannesburg to showcase some of the astounding projects that have been completed with glass blocks. Martin Jedynak, Seves technical manager from Germany, joined Gaspari and gave a practical workshop on installation techniques and methods for glass block installations. According to Gaspari, the building industry’s interest in glass construction has continued to grow over the past few decades. “The annual world consumption of glass blocks is 150-million pieces. The technological advances, structural qualities and colour variety keep improving, giving design professionals more options and flexibility to create world-class constructions,” says Gaspari. Maison Hermès: the magic lantern in Tokyo The Maison Hermès, a 15-storey building in Tokyo, Japan, is an example of one of the high-profile projects that were completed with glass blocks. The building was designed by Renzo Piano and the façade was constructed with specially designed glass bricks by Seves. The Maison Hermès has been called a “magic lantern” of glass blocks thanks to the 13 000 self-supporting glass blocks that reflect the sun during the day and illuminate the internal light at night. “The standard size of glass blocks is 19cm x 19cm x 8cm,” explains Gaspari. The architect and client, however, wanted larger glass blocks that would create a full, uninterrupted glass façade. “Renzo Piano wanted a glass dimension of 90cm x 90 cm, but the technology to make this was not available at the time. Seves decided to innovate and create
068
Vol 11.6 | September 2010
a glass block that was 42,8 cm x 42,8 cm x 12 cm and we developed a rubber system that would fix four of these blocks together with steel rods. The four glass blocks per panel, plus the size of the fixings, made up the 90 cm x 90 cm dimension that the architect required,” says Gaspari. The glass blocks were manufactured in Italy and the panels were fixed into the rubber system in Switzerland. The final panels were then exported to Tokyo where they were fixed on the façade. “This was a €300-million project and it was the first time Seves created something that had never been done before. When you are a painter, it takes creativity and ideas to design a building, but the industrial side that actually has to produce the products often requires technological advances and innovation,” says Gaspari. The glass blocks that were used continue to develop their aesthetic and technological function as they interplay with the building’s interior and exterior walls, transmitting all the lightness, transparency and brightness required. In 2006, the south wing of Maison Hermès was widened by 36 m2 with more glass blocks that seamlessly blend together the old and new to maintain the symmetry that was created when the building was first opened in 2002. Apart from the large dimensions, two additional solutions were used for the Maison Hermès glass blocks: More prominent edging, making it possible to improve the positioning of adjacent blocks. The visual effect obtained means that the metallic supporting structures are hidden, thus reducing the “gap” between the blocks Painted metallic sections marking the edges of the block; an elegant and sophisticated detail which accentuates the luminous reflection of the building “The challenge of the Hermès project meant many years of experimentation for us to develop the production skills necessary to meet this project’s goals. Since then, many prominent architects have used these glass solutions to create great projects all over the world,” concludes Gaspari.

Bespoke glass and aluminium installations at FNB
Centurion Glass & Aluminium (CGA), leading bespoke glass and aluminium constructors, recently installed a variety of glass solutions at the new FNB (Block G Parkade and Office Refurbishment) Development in the city centre of Johannesburg. CGA joined forces with ICM Architectural Studio, SIP Project Managers and BWR Quantity Surveyors to supply and install the latest products at the bank’s refurbishment project.
The 3521M2 Technal MX curtain wall was installed, providing superior load distribution and less deflection. One of the reasons the system was chosen was its strength as it is able to hold large, heavy glazing units. The 294M2 glass façade screen, which was assembled on site, were also specified for the project. .The refurbishment of the FNB offices in Johannesburg began in May 2009 and CGA’s involvement, which also included side-hung windows
as well as single and double doors, lasted 16 months to completion. Martin Volker, Group Marketing Manager of AG Industries, says that double-glazed units were also chosen in order to optimise the comfort of the employees. “AGI supplied Insul-Therm® Eclipse Advantage Grey double-glazed units to achieve maximum thermal efficiency and achieve energy savings,” said Volker before adding that GlassKote was also used as external cladding and that 12mm Cool-Lite toughened safety glass was ‘spider-fitted’ to the glass curtain wall on the East façade. Streamlining operations Only a few years ago, CGA was acquired by Accentuate, which led to CGA’s becoming part of the infrastructure division of the Accentuate group along with FloorworX. This acquisition has enabled Accentuate to provide more niche products to their customers and proves that CGA is one of the leading manufacturers and installers for the commercial retail and top-end residential markets. The company has developed a strong local presence and in the past completed various projects in neighbouring countries such as Mozambique, Botswana, Swaziland and Angola. Fred Platt, CEO of Accentuate, comments: “Accentuate is a group of world-class companies serving the construction and infrastructural development markets, with a strong presence in South Africa and a focus on the construction economies of the developing African market. Strategically, Accentuate has invested in CGA with the aim of leveraging off existing relationships with professionals and contractors, while at the same time transforming the product and service offerings within the glass and aluminium industry. This segment of the market provides opportunity to combine function and styling while at the same time addressing many of the concerns around energy efficiency and green design. As a group we are excited as to the prospects that this division holds,” concludes Platt. CGA Tel: 012 666 8000 Fax: 012 666 8007 E-mail: info@cgaindustries.co.za Website: www.cgaindustries.co.za

15 Alice LaneTowersin Sandtonis anewand iconicbuildingthatfeaturesaverticallycurvedcurtainwallthatprotrudes past the outside of the structure and an extension of the curtain wall above roof level, with the main glass façade consisting of a variety of patterned glass elements. Dow Corning structural glazing sealant, supplied by a.b.e. Construction Chemicals, has been specified for this project and Doug Richards, technical sales consultant for a.b.e., says Dow Corning 993 structural silicone and Dow Corning 813C silicone sealant are being applied to about 13 000m² of the façades of the high-rise building by sub-contractors Grinaker-LTA Façades, the glass and aluminium curtain walling division of the main contractors for this project, Grinaker-LTA Building. Richards says Dow Corning 993 is a two-component neutral-curing silicone sealant which can resist exceptionally high stress levels caused by wind, thermal dilatation and the constant weight of the glass units. “The sealant features superb structural capabilities together with enhanced adhesion to substrates such as approved coated, enamelled and reflective glass; anodised and polyester-coated aluminium; and stainless steel,” he states. “Dow Corning 813C is a one-part, neutral-curing and low-modulus silicone sealant particularly suitable for weather seals, expansion joints and perimeter building joints. It offers durable adhesion to porous and non-porous surfaces such as concrete, masonry, brick, PVC-U, wood, and glazed surfaces. It resists ozone and UV radiation as well as extreme temperatures, and can cope with joint movement of up to 50% of neutral joint width,” Richards adds.

Looking towards the future There is a wide range of technologies and materials that design professionals can use to regulate lighting, temperature and indoorcomfort.Stuffingalloftheseentitiesintoonebuilding,however,doesn’tnecessarilymakeabuilding“intelligent”.From automationsystemsthatmakebuildingsmoreenergy-efficient,tonewstandardsthatdemandintelligentdesignprinciples, Walls & Roofs asks industry leaders for their opinions of what a truly intelligent building is. The concept of an intelligent building dates back to the early 1980s and the definition has evolved with different emphasis, mainly driven by new technologies and changing needs in the built environment. In the early 1980s, an intelligent building was defined as “a building automatically controlled to function”. Between 1986 and 1991, an intelligent building was one that was “capable of responding to changing needs” and from 1992 to present an intelligent building is one that has “features effectively satisfying the changing needs” (www.ibuilding.gr). According to SMART – ACCELERATE project, the requirements for an intelligent building are: • The built environment should be productive, safe, healthy, thermally, aurally and visually comfortable. • The building has potential to serve future generations: sustainability or adaptability over the life cycle of the building and safeguarding the earth and environment resources. • Financial aspect: the building can be built within some cost con straints whilst retaining market value. Source: www.ibuilding.gr Building automation systems Various access control, energy, communications, HVAC systems and lighting are now automated. Worldwide, Building Automation Systems (BAS), which include software and services, continue to grow every year and one of the key drivers for this market is energy management.

According to ABI Research, the market for BAS is set to grow 3% globally between now until 2015, when the total market will reach a value of more than US$36-billion (www.abiresearch.com). “Government financial incentives and regulations as well as organisations’ own financial and environmental goals are coinciding with a drive to open up building automation systems to wider network management and integration, drawing companies such as IBM and Cisco into a market traditionally dominated by more specialist global companies such as Johnson Controls, Honeywell and others,” comments ABI principal analyst Jonathan Collins. The potential and pitfalls of lighting control According to the Lighting Research Center, the potential for substantial energy savings has made the use of automated lighting controls such as occupancy sensors, timers and photosensors commonplace in modern buildings (www.lrc.com). Over half of the large commercial buildings (averaging 200 000 m2) surveyed by the Wisconsin Center for Demand-Side Research included a building automation system. The National Lighting Product Information Program in the US prepared a document entitled Lighting Answers to explain the potential pitfalls, opportunities and benefits and to direct lighting specifiers to resources for further information. In addition to energy savings, building automation lighting systems offer the following benefits:

“An intelligent building is one that provides aproductiveandcost-effectiveenvironment through optimization of its four basic components – structure, systems, services and management – and the interrelationships between them.” The Intelligent Buildings Institute, US
According to Ron Milburn, Technical Support Advisor from Legrand, automatic lighting systems have become extremely technologically advanced over the past few years. “The industry has made huge strides in perfecting this area of building automation systems. The solutions available are changing every day,” says Milburn. Milburn also explains that in South Africa there is a difference between the products bought for new and existing projects. “We are seeing an increasing number of clients looking for energy-saving solutions. In new builds, however, clients are opting for smart installations that manage a variety of electrical applications but refurbishment projects are generally only buying specific solutions, such as sensors that turn the lights on, and so forth,” says Milburn.
Enhanced operation scheduling Detailed occupancy reports Ability to share occupancy information with other building systems Ability to minimise peak demand and reduce energy costs Ability to control and monitor lighting throughout a building and multi-building facilities
Although some of the systems available may simply schedule equipment, more sophisticated systems (which run on customised software) are able to develop a type of logic that has the ability to learn occupancy patterns and anticipate when to turn on artificial lighting and warm up a building.

How automatic lighting systems became ‘intelligent’
Originally, lighting control systems used to control equipment in a single room, because they were “centralised control systems”, meaning that all the controlled circuits were wired to a single panel that performed a lighting control function only. Modern building automation systems, known as “distributed control systems”, have computing hardware and software that are distributed as a network that consist of microprocessor-based control modules and normal computers. The control modules in these systems are able to communicate with each other and act together as an “intelligent” whole. Another advantage of direct digital control technologies is that they have the ability to be extendible virtually without limit, so that all the lighting in a building can be controlled by a single system that also monitors other automated systems such as the building’s HVAC, security, elevators and more.

Combining different aspects of an intelligent building The BAS market comprises a computerised, intelligent network of electronic devices, designed to monitor and control the mechanical and lighting systems of a building. Although experts say that automation systems are a key aspect of design and construction, they don’t necessarily make a building intelligent. ABB, a global leader in power and automation technologies, installed various intelligent building management solutions at the Circa on Jellicoe, a new multimedia art gallery designed by South African practice studioMAS. Circa, which comprises three levels with the public ground floor consisting of 106 m2 of craft exhibition space, is a 177 m2 doublevolume, multi-purpose building. The main structure is cast in situ concrete and the façade cladding consists of anodized aluminium fins which are attached to the concrete by steel angles and bracing. Electrical company Willchrist Projects were tasked with the design and installation of the ABB KNX Building Automation system, which needed to incorporate the architect’s need of specialised lighting that

Zinc cladding and roofing

According to Stephen Wilkinson, the durability of RHEINZINK as a roofing and cladding material is inherent in the zinc itself and is attributed to the ability of zinc to form a protective patina (film) preventing the zinc from oxidising (rusting). “The formation of the patina may occur within 3 months to 3 years depending on the aggressiveness of the environment. The composition of the patina formed depends on the project’s location. RHEINZINK is highly corrosion-resistant
inland as well as in marine environments. However, regardless of location, patina removal rates are relatively similar,” says Wilkinson. Inland, the RHEINZINK patina forms normally whereby the zinc undergoes a two-step chemical reaction. Firstly, it is combined with water and oxygen which forms zinc hydroxide and, secondly, with carbon dioxide in free-flowing air. This reaction forms a dense outer contact layer insoluble to water and a packed inner layer of alkaline zinc carbonate. Zinc in maritime atmosphere A\long coastlines in maritime atmosphere, zinc combines with salt in the air to form zinc chloride (ZnCl2) or zinc oxychloride (Zn2OCl2). Like the zinc carbonate, the zinc chloride encapsulates the zinc inhibiting oxidisation. Direct salt water or sea spray contact reduces the longevity of the material. While evaporated salts leave a whitish residue on the zinc, when washed off, the zinc patina evolves blue-grey-green in colour. The removal of the patina layer by scouring is defined as corrosion. The most aggressive corrosion rates are in polluted industrial areas with high sulphur dioxide content. “In these areas the removal rate by scouring of the patina is in the range of 1,0 to 1,2 μm per year establishing the lower half-life limit of durability between 80 and 100 years. Otherwise the service life of RHEINZINK as a roofing material ranges between 80 and 150 years,” concludes Wilkinson.

Continued from page 75 would add to the ambience and aid with the showcasing of artworks. The system controls the lighting of the three specially designed floors for the display of various works of art. The installation consists of 4 of the 6325 Triton switches with LED displays to enable switching on and off of up to 10 groups of lights at a time. These switches have been installed on various levels to control multiple groups of different types of lights. Over and above the multiple switches, 12-fold and 8-fold actuators as well as a number of dual dimming modules have been installed in the distribution board to enable the Triton switches to switch the multiple groups of lights on and off from various locations. A number of occupancy sensors were installed to contribute to the group’s energy efficiency drive. The ABB infrared Busch-Watchdogs, that have infrared technology which reacts as soon as it detects body heat, were installed. This product includes Lux features that also automatically detect the natural light in the room and then dim accordingly. Halogen lights and LED colour-changing lights were also installed and these lights are controlled by the ABB Dali lighting controller that intelligently gives feedback from all lights installed to advise on replacements. From smart to wiser homes Global specialists in energy management, Schneider Electric South Africa, recently launched Wiser Home Control – a system that interlinks the electrical, multimedia and telecommunications systems of a household. A unique feature of Wiser Home Control is that it enables the end-user to control equipment from preset shortcuts and via 3G mobile phones or web-enabled devices. Turning on a multi-room audio system from outside, setting bed lamps and music that comes on gradually (followed by curtains opening) as an alarm, and an alarm system that deactivates night mode have all become possible with this new automated electrical management system. Users can use phones or computers to monitor if all is well at home while they are away and reset security systems if there are false alarms. Changes or adjustments can be easily made to the program via the Internet, thereby reducing the need and cost for technician intervention, and time spent waiting for a technician to arrive on site. Manage electrical, multimedia and telecommunications from 3G mobile phones.

“An intelligent building is one that maximizes the efficiency of its occupants and allows effective management of resources with minimum life costs.” European Intelligent Design Building Group
Schneider Electric South Africa’s Buildings Product Manager, Nico van der Merwe, says that an increasing number of industry professionals have become aware of the different products available and are looking for intelligent, automated systems. “We have seen tremendous interest from real estate developers, decorators and installers for a home control solution that can adapt to lifestyles and work practices and, at the same time, improve and reduce energy use,” says Van der Merwe. “We offer solutions that enable 30% energy savings without compromising on comfort, performance and reliability. We are committed to helping individuals and organisations make the most of their energy, and hence excited to bring Wiser Home Control to the market,” says Van der Merwe. In an interview with Ron Zimmer, the President of the Continental Automated Buildings Association (CABA), he said that intelligent technologies in both new and existing buildings can enhance energy efficiency, reduce operating costs and reduce the burden of environmental dependency of buildings, thereby making them greener (www.automatedbuildings.com). “The deployment and success of intelligent and green solutions will ultimately rest on the capability and experience of the project team. Most importantly, the justification for deploying intelligent technologies in a project will rest entirely on the return on investment the project promises since this is the most tangible measure most property owners recognise. Building owners and managers realise multifold financial benefits from utilising intelligence and green technologies, including: lower energy costs, lower maintenance costs, lower repair and replacement costs, and increased occupant comfort and satisfaction and the resulting productivity benefits. One of the value-added outcomes is increased employee productivity,” said Zimmer (www.automatedbuildings.com). “All of these factors are providing the cost justifications that have long been needed to warrant end-users making significant investments in the installation of integrated building automation systems. Whether from a green building or energy management perspective, intelligent buildings provide owners with the means to increase efficiency and meet their business objectives by controlling costs and potentially extending the life of a building.

In2005,RobertsonVentilationIndustries(Pty)Ltd(RVI)signedamanufacturinganddistributionlicensingagreementwithColt International.ThesigningofthisagreementhasenabledRVItocombineColt’sextensiveSmokeandFireVentilationproductand systemtechnologywithRVI’sindustrialventilationproductandsystemknow-how;therebyenablingRVItooffercomprehensive ventilation solutions for both commercial and industrial projects and their end-users. In conjunction with Colt International’s extensive smoke and fire ventilation range of products and systems, RVI, through its solar shading division, was able to re-introduce Colt’s sun shading products to the South African market. “Together with Colt we (RVI) recognised that the sun shading market segment offered good long-term potential. We also identified that there were a number of existing Colt sun tracking solar shading system installations that were not functioning as designed and that these systems would have to be revisited and refurbished where necessary,” said Chris Edwards of RVI. One of these systems was installed at the Head Office for the Department of Science and Technology at the CSIR Campus. “When Bild Architects (in association with Terra Ether Architects) were commissioned to design the new Head Office we were requested to include sound design and building principles particularly as it would apply to Sustainable Green Building. The shading system was to be installed on the West façade of the quadruple level ‘Corporate Street’ atrium. This circulation spine accommodated the vertical transportation, pause

areas, formal meeting rooms and access to the media centre and main auditorium. The shading system was required in order to protect the building from the fierce western sun. After some investigations, the Colt International Solarfin Shading system was chosen on its performance criteria and visually pleasing aesthetics,” said Eddie Pretorius from Bild Architects Shortly after commissioning and handover the shading system regrettably became non-functional and some blades dislodged. “Fortunately, a chance meeting with the supplier resulted in Colt International and RVI completely stripping, overhauling and re-commissioning the existing installation after a thorough investigation revealed that the previous license holder had not installed the system in accordance with the manufacturer’s guidelines and specifications,” said Eddie Pretorius from Bild Architects. “We are delighted to note that the system has been re-commissioned and is in perfect working order thanks to the sterling effort by both Colt International and the new license holder, Messrs Robertson Ventilation Industries (Pty) Ltd,” said Eddie Pretorius from Bild Architects.

After:
The louvre blades remain open in the morning to let light into the building. During the course of the afternoon the aerofoil louvre blades close incrementally, protecting the Western façade against the fierce Western sun.
The louvre blades of the automated sun shading system are perpendicular to the sun at all times in order to optimise shading while still maximising daylight into the building.
The CSIR – Department of Science & Technology Building sun shading system comprises the following: • • • • •
A system of Colt Solarfin CEL300/50 one-piece extrusions and ML150 vertical mullions together with Colt International’s fixed and floating end technology. 1 x Colt Soltronic Control Module 2 x Colt Mak 8 Relay Boxes 1 x Colt Light Sensor 1 x Colt Wind sensor
About the system Colts fully automated sun tracking/shading system, Solarfin, was specified and installed on the Western façade of the building. Horizontal aerofoil extrusions are mounted between vertical aluminium mullions; in order to cater for thermal expansion and contraction each aerofoil incorporates both fixed and floating end technology. The primary prerequisite of the system was for the aerofoil blades to remain open in the morning; thereby letting light into the building and allowing people to feel connected to the outside environment. During the course of the afternoon the aerofoil louvre blades automatically and incrementally rotate and close protecting the building from the afternoon suns heat and glare. At the end of each day, the aerofoil louvre blades end up in the fully closed position and at night they rest in a 45° position. The objective with automated sun shading is for the louvre blades to be perpendicular to the sun at all times in order to optimise shading while still maximising daylight into the building. “The challenges that faced RVI in this project were significant,” said Edwards before he listed the following project-specific challenges:
• • • •
Limited and difficult access to the workface as a result of the water feature at the bottom of the shading system Machinery constraints due to indigenous garden all around the building Working on and within a building that is fully occupied and functioning Overcoming the unknown elements associated with working on another company’s installation
“We are however pleased to report that the system was re-commissioned during the course of May 2010 and is now functioning as designed. We are keeping an eye on the system to make sure it remains fully operational and are currently finalising a maintenance agreement for the shading system with the CSIR – DST,” added Edwards. RVI Would like to thank Bennie Hlongwane from the CSIR - Department of Science & Technology for his assistance during this process.

Everybody gave their ‘thumbs up’ to the project,” said LLumar representative Jane Kannikar. “This was a winning solution for everyone.” Product Information LLumar Energy Saving Window Film can enhance the performance of glazing systems and significantly reduce energy consumption due to the heat rejection qualities of the film. According to LLumar, the estimated annual energy savings can be as high as 15% with improved HVAC efficiency in buildings that are retrofitted with CPFilms, according to professional energy audits. The LLumar Energy Saving Window Films are made from polyester laminates and bonded coatings. LLumar film products are able to reduce solar energy heat gain by up to 80% and block 99% of damaging UV rays. They improve the comfort of occupants by reducing the heat and glare in the building. The Low-E (low-emissivity) films improve insulting properties for all-year-round savings.
Thailand’s leading entertainment company’s building refitted with the LLumar Energy Saving Window Film.
According to WPE, not only did employees complain about the glare from sunlight and heat within the offices, but the glass exterior also contributed to high energy bills as the airconditioning units were over-utilised in the building. Energy-efficient solutions LLumar, which offer a complete line of architectural window tint, installed R-20 SR CDF, their highest heat-rejection film, to the external façade of the building. After thorough analysis, LLumar also recommended that another type of film, N-1035B SR CDF, be installed in the front lobby and the atrium of the building to alleviate the heat and glare of the sun. After the window films were installed, WPE’s building management team reported that the project was conducted safely and professionally with minor interruption to the employees, who were able to continue their day-to-day operations during the installation.

Verifying energy savings from window film solutions Industry-leadingglassfilmsupplierLLumarrecentlycommissionedanindependentmeasurementandverificationstudyto clearly demonstrate the energy-saving properties of their energy-control window films. Johnson Controls, a leading global Energy Service Company (ESCO) joined forces with CPFilms Energy Solutions Division to launch a controlled and well-defined study, which included a computer-driven model which simulated energy savings, using the US Department of Energy analysis method to serve as a benchmark. The study lasted twelve months and the time frame, coupled with the location, was deliberately chosen to demonstrate energy savings over both the summer and winter seasons. The study also clearly shows that energy-control window films are a product that not only needs to be used in warm climates. LLumar E-1220 Low-E solar control and insulating film was installed on an eight-storey commercial office building near Chicago in Illinois. The building has a conditioned space of 59,000 m2 and its windows are single-pane bronze-tinted glass. Heating and cooling of the building is provided through all-electric unit ventilators. Less than 3-year payback Over the twelve-month period in which the study took place, Johnson Controls measured energy savings using IPMVP Option C, a methodology fashioned by IPMVP Inc. (International Performance Measurement and Verification Protocol), a worldwide non-profit organisation which develops products and services to aid in the measurement and verification of energy savings from energy efficiency projects. IPMVP Option C-measured energy savings of 8,8% were noted, yielding a payback in less than three years.

Sophisticated security/access control and fire prevention installations and ongoing maintenance for the University of Cape Town’s 3 (upper, middle and lower) Rondebosch campuses are provided by FIRESPEC.
Fire and security safety at UCT Specialised maintenance is a core service offering of FIRESPEC, a protective systems company that services South Africa nationally from its head office in Cape Town. The company specialises in both active and passive fire protection and security services, ranging from the installing of new state-of-the-art hardware, to extensive servicing and maintenance contracts of existing systems. Sophisticated security systems at UCT campuses One of FIRESPEC’S high-profile, ongoing maintenance contracts is the company’s partnership with the University of Cape Town at all 3 (upper, middle and lower) Rondebosch campuses. UCT’s campuses have evolved over many decades and their security systems are consequently a cross mix of differing generation technologies and vintages. Over recent years, the need for more sophisticated security systems arose and the servicing of this diverse array is in the hands of the dedicated FIRESPEC team with technicians located on all 3 campuses. The company’s experience spans more than 3 decades of systems and the combined knowledge of FIRESPEC personnel is available to the client.
Access at the library on the main campus is controlled by a set of turnstiles and electronically facilitated by card-readers.
Critical fire protection and control Fire protection and control is also an area of critical importance, parallel to security, and an impressive mix of different systems was installed by
the university and upgraded as needed to meet the increasing safety requirements of the new South African building codes. An outstanding example is the main computer centre located on the upper campus. Entry to the centre is electronically controlled, fire alarm and evacuation systems are in place, and the nerve centre is monitored by a sophisticated fire and smoke detector service that automatically triggers FM200 fire suppression system. This service should seamlessly work in the unfortunate event of fire and ensure that the university’s valuable IT assets are protected in the most efficient way possible. Access control Elsewhere on the campus at the main library, access is controlled by a set of turnstiles and electronically facilitated by card-readers. Passive fire control features at certain libraries include emergency fire rollerdoors that are automatically activated. All over each campus, CCTVs monitor sensitive access points and information is streamed into control centres, along with fire control data that is monitored and coordinated by the Maestro system. The Maintenance Unit is headed by Cecil Meyer, who overseas a team of 15 technicians. FIRESPEC is also able to conduct Fire Regulations Compliance Surveys, which are carried out by certified, highly qualified technicians. Leo Slootmans, CEO of FIRESPEC, comments, “UCT is an example of the comprehensive one-stop service available from FIRESPEC.” “The presence of dedicated and highly qualified technicians – available on call 24/7 – is a great reassurance to our clients,” he concludes.

ThermocousTex’s ease of handling, installation and long term maintenance are also some of the reasons that professionals specify this product for high profile projects. The product has been tried and tested and its application and quality has proven the long term benefits of using this product to the construction industry. “Besides Gautrain, we have been involved in a number of recent high profile projects,” says Thomas Datel from Frame Industrial. “ThermocousTex is very proud to have contributed to a number of projects that have been important to the success of the World Cup, such as Soccer City, King Shaka Airport, Cape Town International Airport and Holiday Inn hotels.” Over the past few years, the insulation industry has been referring to SANS 204, the new energy legislation. On 11th June 2010 the legislation was gazetted and is now part of the National Building Regulations. Within the next few months, SANS 10400 XA will also be mandatory in all buildings after public comment on this energy efficiency legislation. The cost implications of complying with the new regulations vary from R12 500 to R27 500 extra on a house of a 150m², which equates to between R210 and R450 per month over five years. These costs, along with the predicted electricity price increases, make it financially viable to insulate even without legislation.

Beware of cheap
imitation
roof tiles! MarleyRoofing’sM22isawell-known,premiercoatedconcreterooftile.Thehigh-qualityindustrialcoatingis basedonapureacrylicemulsionpolymerspecificallyformulatedforconcreterooftilesineveryenvironment.
The company warns that contractors and specifiers should beware of cheaper, imitation painted tiles. “The M22 coating is applied to standard throughcolour tiles during manufacture under precisely controlled conditions. After curing it becomes as much an integral part of the tile as the body colour it seals in,” comments Paul Reed, marketing manager at Marley Roofing, when explaining how imitation tiles cannot compare with Marley’s M22. Marley M22-coated tiles have over 25 years of proven performance, enabling architects, developers and homeowners to specify beautiful roofs with impressive benefits: rich colour, guaranteed colour uniformity and virtually no maintenance requirement. Roofing innovations since 1981 In 1981, Marley Roofing achieved a major breakthrough in the concrete roof tile industry in South Africa with the successful development of its unique maintenance-free M22 coating system. The tile finish is capable of withstanding the extremes of South African conditions and the
Marley’s M22 coating enhances the beauty of the tiles with its silk-textured finish and rich natural colours.
Maintaining vibrant colours Marley’s M22 coating enhances the beauty of the tiles with its silktextured finish and rich natural colours. The consistency of the colours is also guaranteed from batch to batch, a benefit best appreciated on large developments extending over a long period of time. Function and protection The M22 coating is formulated to inhibit the growth of algae and fungi, thus eliminating the periodic pressure-cleaning of the roof in hot and high humidity areas. Weathering is also greatly improved as the coating provides long-lasting protection against surface erosion.
product’s rich colour as well as durability has proved itself as the safest route to long-lasting colour uniformity on the roof. Reed explains that M22 has passed the most stringent laboratory and outdoor tests. “This tile coating is totally unaffected by heat, cold, humidity, UV radiation, heavy rains, hail, salt-laden breezes and industrial pollution,” says Reed. In a simulated ‘acid-rain’ test carried out by the National Building Research Institute in Pretoria in 1985, M22-coated tiles were compared to other concrete roof tile finishes and proved far superior, showing no surface deterioration (test results are available from Marley Roofing on request).

Eliminating efflorescence Efflorescence on unprotected concrete roof tiles – often referred to as ‘lime bloom’ – is a natural, unpredictable phenomenon which can disturb the appearance of the roof temporarily. M22-coated tiles eliminate the efflorescence problem and ensure that the roofing tiles look their best from the start, and better throughout their long life. “Due to their exceptional performance and aesthetic qualities, Marley M22-coated tiles are a winning choice for all pitched roof applications in every environment. M22 is the long-term solution for lasting colour uniformity,” concludes Reed. Marley Roofing Products Tel: 011 316 2121 E-mail: olifants@marley.co.za Website: www.marleyroofing.co.za

The restoration of Hostel 33 was a milestone for the Lwandle Migrant Labour Museum in which Corobrik played a significant part.
Corobrik helps restore historical museum After visiting the dilapidated site of Hostel 33 which forms part of the Lwandle Migrant Labour Museum in the Western Cape, Corobrik’s architectural representative in Cape Town, Allistair Cloete, was instrumental in helping to restore the structure to highlight its rich history. “This project was especially significant to us because one of the forty hostels in this area was originally owned by Corobrik over fifty years ago,” says Cloete. “The hostel was in dire need of repairs to restore its original condition, and after speaking to the architects it became apparent that the budget for restoration was too small.” As a result, Corobrik decided to donate the 500 Clay NFX (Non Face Extra) bricks needed for the renovation. “We would gladly have sponsored more bricks had they required it but, as the hostel needed preservation not enhancement, only a small amount of bricks were needed,” says Cloete. Noëleen Murray, architect and board member of the Lwandle Migrant Labour Museum says: “With the dawn of democracy in South Africa the government turned the hostels of Lwandle into family-type accommodation. Residents however felt that at least one hostel should be preserved to show the world the injustice that migrant workers faced.” “On Workers Day, 1 May 2000, the Lwandle Migrant Labour Museum was officially opened by poet and former resident, Sandile Dikeni. The museum’s exhibits commemorate the trials, tribulations and triumphs of migrant workers and hostel life in Southern Africa.” “Corobrik’s spontaneous and generous donation of bricks for this restoration process is gratefully acknowledged. Their assistance and continued support is tremendously appreciated,” says Murray. According to Murray, Hostel 33 is an integral part of Lwandle Museum and the idea to preserve the building as a heritage site occasioned the formation of the Museum and permits the Museum to recount the circumstances migrant workers were forced to endure. As the only remaining hostel which was not converted in the Hostels-to-Homes project of the 1990s, it is a site of considerable significance.

Waterproofing:
Prevention is always better than cure Water seeping into parapet walls and balcony floors which aren’t properly waterproofed can lead to unsightly stains and problems, such as streaking, peeling paint or nasty fungal growth.
“The correct topcoat must be used to prevent cracking; a quality top coat with a seven-year lifespan is recommended. Dawid du Plessis, technical services manager at Prominent Paints, says, “Unsealed parapets should be treated with a fibre-reinforced, water-based product like Fibre Seal. As with any coating, the finish is only as good as the undercoat, so be sure to first remove loose paint, fungal growth or dust. Priming should then be done with an appropriate primer, such as Damp Cure, which is moisture-tolerant.” The spreading rate for Fibre Seal is 1m2/L; two coats should be applied, with 24 hours allowed between coats for curing. The second coat should be applied perpendicularly to the first. “This enables the fibres to create a lattice and improves the waterproofing capability.” When coating the vertical surface of a parapet it is important to overlap the coating by approximately 10cm onto the horizontal areas. “This ensures complete protection and prevents later problems with bubbling and cracking on these surfaces.” When choosing a topcoat, Du Plessis says it is important to remember that a fibre-reinforced system is more flexible than raw plaster. “The correct topcoat must be used to prevent cracking; a quality top coat with a seven-year lifespan is recommended. In addition, sheen or textured coatings tend to be more compatible than a matt finish.” Homeowners with face brick parapets that require waterproofing are unlikely to paint over the natural finish. Du Plessis says Surface Sealer is an appropriate choice here. A silicon-based water repellent, it will permanently waterproof stone or face brick without any colour enhancement.
He suggests a liberal application of Progold Fungal Wash before sealing the bricks to eliminate fungal growth. Du Plessis says the task is more complicated when waterproofing balconies. “The biggest problems here are related to slope, lack of drainage, or drainage holes being incorrectly placed. Many balconies are tiled; applying Damp Cure and Fibre Seal before laying the tiles can certainly help, though you should ensure that the adhesive and grout used are also water-resistant.” Because there are so many factors that can impact a balcony, he says the best option is to contact the Prominent Paints customer care line. “You will receive a site visit and professional advice, essential to waterproofing a balcony successfully.” Du Plessis also stresses that when building or painting, never neglect waterproofing. “Remember that prevention is far better than cure. Going for the cheap option at the start will end up costing far more in the long run,” he concludes.

According to Pepe Espinosa, GM’s global specialist in building standards and warehousing, it was imperative to produce this new 38 000m2 warehouse in accordance with GM’s global best practice. “This warehouse looks and will operate exactly as other GM warehouses around the world,” said Espinosa. To meet the strenuous quality demands of the project, the professional team of architects, quantity surveyors and structural engineers called on Global Roofing Solutions (GRS) to provide the roof cover and cladding for the R250-million project which started in August 2009. The GRS “Klip-Lok 406” pre-painted aluminium sheeting was selected for its durability, wind resistance and water resistance qualities. The Klip-Lok for this entire project was roll-formed on site as the majority of the roof sheets were in excess of 60 metres. GRS further supplied 6 500m2 of side cladding in Supa-Clad pre-painted aluminium. “The experienced design and architectural assistance of the GRS team provided a platform for a confident product choice and their technical advice assisted us in completing this significant project in the Eastern Cape,” said Wessel Lategan from Cladall Roofing, the GRSapproved contractor. “We’re delighted to have been part of GM’s Pan-African expansion and appreciate the trust that the designers and specifiers of major

Covering the Cape Another large project that GRS was involved in is the Integrated Terminal and multi-storey parkade at Cape Town International Airport. GRS supplied 29 000 square metres of Klip-Lok 406 concealed roofing sheets for the main terminal and another 20 000m2 roof sheet for the parkade. GRS products were furthermore used at the Broadway Boulevard Mall in Somerset West, the Cape Gate Medi Clinic, the Integrated Waste Management Facility in Kraaifontein, 15 On Orange Hotel, and Dreamworld Studios in Stellenbosch. “The vision of GRS is to be the supplier of choice to the roofing market in Africa,” concludes Jacobsen.

Umhlanga Ridge
New Ridgeside ‘green’ office developmenttakingshape A new office development in Umhlanga Ridge is well underway, reports contractor Grinaker-LTA, which is undertaking the R107-million building contract. “The total construction area of 30 183 m2 consists of a four-storey office block and a three-level parkade,” explains Rankin Burger, contracts director at Grinaker-LTA Building East, “and the project is scheduled for completion by 5 November 2010.” This upmarket office complex will boast high-quality finishes, and Burger says that the design of the building incorporates various features that form part of the client’s goal to develop a 4-Star Green Building, meeting the specifications set out by the Green Building Council of South Africa, of which Grinaker-LTA is a member. These include the Environmental Management Plan; recycling or re-use of construction waste generated on site – including rubble and scrap timber, where possible; and all paints and adhesives conform to the required Volatile Organic Compound levels. He says a further initiative that could contribute to achieving the 4-Star grading is to replace the precast concrete façade panels originally specified in the development’s design with resocrete panels, which are made of a resin composite that is sourced locally. “These panels are far lighter than precast concrete, thereby reducing haulage and lifting costs, and they are much easier and quicker to install,” he explains. A total of 13 601 m3 of concrete will be used in this construction project, along with 1 261 tonnes of reinforcing steel, 700 000 bricks and 58 798 m2 of formwork. A total of 550 piles will be sunk. Burger says the team on site is working to an extremely tight contract duration. “It’s a testing project, but Grinaker-LTA is on track, with the bulk earthworks and piling completed and the concrete structure nearing halfway. Approximately 6 500 m3 of concrete has been poured to date.” Grinaker-LTA Building Tel: 011 578 6200 Fax: 011 578 6384 Email: npotgieter@grinaker-lta.co.za Website: www.grinaker-lta.com

CMA Awards for Excellence entries CMA members have been and continue to be involved in some of the country’s most prestigious projects, including the stadiums for this year’s World Cup soccer tournament and products for the Gautrain rapid rail link. These and other noteworthy projects are being featured in this year’s CMA Awards for Excellence competition. Although the 2010 competition has not attracted a record number of entries, the standard of the submissions remains exceptionally high, both in the quality of the actual projects and in the photography. This is especially so in the Paving, Concrete Retaining Block (CRB) Walls, Roof Tiles and Innovative categories and the judges were hard-pressed in their decision making. The judging took place on July 21st and 22nd and the results, based on three tiers of regional, national and trophy awards, will be announced at an awards banquet in Gauteng on 6th November, after the two coastal awards ceremonies have taken place in Cape Town and Durban during October. Five as opposed to four trophy awards will be made this year. The ultimate winning entry in the Concrete Retaining Block (CRB) category, which in the past shared a trophy with Suspended Concrete Floor Slabs and the Infrastructural and Innovative Concrete Products categories, gets a trophy of its own this year. This is due to the fact that over the past 10 years the number of CRB entrants has increased substantially, reflecting the success and growth of CRB walls as an embankment retaining system. The winners of each category in this year’s awards will be featured by WALLS & ROOFS in Journal 01/11. Watch this space!

BBEE property fund to focus on sustainable
wealthcreation The recently formed BBBEE property fund, Supreme Commercial Property Fund, promoted by Hermans & Roman Property Solutions and launched in May, is currently earmarking sustainable community and entrepreneurial initiatives as priority areas for the management of the fund. One of the goals of the fund, which will be operable in November 2010, is the transformation of property ownership, to allow BBBEE consortia to participate at a significant equity level in Supreme. To date, Supreme has acquired commercial properties to the value of R3,8 billion which accounts for 51 buildings with a gross lettable area of 436 500m², primarily government-occupied and leased, with a further R2 billion under negotiation. “Supreme’s primary objective is to create true wealth for disadvantaged communities and individuals and create opportunities that still elude the previously disadvantaged within the commercial property arena. The divide between rich and poor, the haves and the have-nots, is increasing. However, with the establishment of Supreme and the initiatives that are planned, broad-based empowerment and equal opportunity for the less fortunate will be achieved,” says Leslie Hermans, Group Chief Operating Officer of Hermans & Roman Property Solutions, the promoters of the fund. The fund will be structured as a property loan stock entity which will initially be unlisted with a view to listing within the next 3 years. “The initiatives prioritised by Supreme will benefit a large number of South Africans, at an individual, SMME and community level, who wish to operate in the South African commercial property arena,” says Hermans. A new type of business model The industry is largely dominated by listed sector companies and institutional investors. “One of the key reasons for the lack of black participation at an equity level within the property industry has been the lack of access to capital for black individuals and BBBEE consortia. We have created a business model within Supreme that deals with corporate social investments and enterprise development at an equity level. This model allows Supreme to differentiate from strategies that
most South African companies adopt in dealing with corporate social investment and enterprise development,” says Hermans. These goals will be achieved through the Supreme Commercial Property Trust, which is being established for the benefit of previously disadvantaged communities and charitable organisations. Priority groups identified are women, youth and the disabled. Developing property entrepreneurs Consultancy and partnerships with organisations and businesses that promote initiatives with similar objectives (through entrepreneurial training and facilitating access to finance) will facilitate enterprise development at an equity level, with the primary objective of developing property entrepreneurs. This model allows for direct and indirect job creation. “It is envisaged that Supreme will dispose of non-core building assets to entrepreneurs who wish to become Landlords and to facilitate the financing process with various financial institutions. We have identified that supporting entrepreneurs is paramount to job creation. Supreme can facilitate the exponential growth of SMMEs and thereby create increased capacity and opportunity for employment at operational levels,” says Hermans. Academy of Learning The Hermans & Roman Academy of Learning is an existing establishment that will continue to facilitate the academic development and training of black property practitioners through accredited, custom and specialist training programmes focusing on property management, asset management, property financial management, public sector and property project management. Training initiatives will be supported by the structured internship programme which allows graduates to acquire practical experience within the different property disciplines and thereafter facilitates the placement of these graduates within the commercial industry, thereby creating a talent pool of young property practitioners that will ensure the sustainability of the industry.

High-spec panels for Rhodesfield Station
Vitraclad panels from Vitrex, South Africa’s leading producer of vitreous enamel steel products for architectural applications, have been utilised on the recently completed Rhodesfield Rail Station near O.R. Tambo International Airport. Cristian Cottino, sales and marketing director of Vitrex, says about 300m² of heavy-gauge cladding was specified by Martinez Architects, to meet some of the functional and aesthetic requirements of this project. The cladding was installed by Vitrex as a sub-contractor to the main contractor, Rainbow Construction, and the panels have been used in three main areas: to form the barriers which separate the commuter areas on the first floor from the tracks below; as a feature wall to add colour to the design of the junction between the two commuter passages; and on the walls of the ticket hall to provide durable protection. “The Vitraclad elements play an integral part in Martinez Architects’ design, both in terms of colour and surface protection in high-traffic areas. The commuter barriers consist of a free-standing integrated system which includes the required mild steel support system and the Vitraclad panels,” Cottino states. Passenger Rail Agency of South Africa’s (PRASA) Rhodesfield Station has been developed as a Rail Commuter Node adjacent to the Gautrain Rhodesfield Station. The project forms part of PRASA’s programme of upgrading the metropolitan commuter rail networks across the country and was also part of the FIFA 2010 Soccer World Cup transport infrastructure programme. “Martinez Architects has specified Vitraclad on a number of their
previous projects and have a long-standing working relationship with Vitrex,” Cottino adds. Vitraclad panels are produced by Vitrex at its Jet Park plant through the fusing to sheet steel of an inorganic coating consisting of glass, oxides and various minerals at temperatures of over 800ºC. Some of the major advantages of vitreous enamel (“porcelain”) steel cladding include being weatherproof and resistant to high UV levels, salt sea air, hail and industrial pollutants; having a wide variety of colours that are permanent, non-fading and a surface requiring only simple, periodic cleaning; the panels are not susceptible to rust, even in extreme marine conditions. The coating is resistant to most alkalis, acids, organic solvents and is unaffected by kerosene. Enamel is also extremely hygienic as the absence of pores on the smooth, hard surface eliminates absorption of dirt and grease, and reduces the presence and growth of bacteria and mould. The hardwearing surface is resistant to abrasive materials and will withstand the effects of wind-driven dust and dirt. Vandal-proof and impact-resistant, it is extremely difficult to permanently mark the surface of the panels with knives, keys and screwdrivers, and unwanted graffiti and spray paint can easily be removed. The surface is also impervious to attack by rodents and boring insects. The panels are non-combustible, with the ability to resist heat of up to 650ºC and continuous temperatures of up to 400ºC. Their resistance to thermal shock is also exceptional – they are able to resist extreme temperature differentials and withstand rapid cooling by water spray from 400ºC to room temperature over a 30-second period. In terms of acoustic and thermal insulation parameters, specific Vitraclad performance requirements can be addressed at the design stage. Finally, Vitraclad panels are environmentally friendly, with a working life in excess of thirty years and minimum maintenance needed, they do not require strong chemicals for cleaning and are fully recyclable.

Banking on increased energy efficiency Last year, FNB earned a prestigious eta award in the commercial category – regarded as South Africa’s premier awards for energyefficiency.Theleadingbankisincorporatingnewenergy-savinginitiativesthatcomplementpreviousefficientlighting and other energy measures, such as optimising secondary voltage through transformers at major bank premises.
According to William Cass, First Rand’s energy manager, the potential benefits from this step alone could see the banking group save about R3-million a year. “When we examined transformers within the group we discovered that they were absorbing electricity at 238 volts rather than the required 220 volts,” said Cass. “Fourteen transformer steps were adjusted to reduce this voltage by one step and this led to a saving of five percent on the Bank City bill – a saving that may sound small, but equates to R70 000 in our main complex. Other buildings that have their own distribution boxes will be evaluated and adjustments will be made where possible.”
New energy saving initiatives at the FNB building could see the banking group save about R3-million a year.
Lowering the airconditioning bill At the same time, the First Rand Group started examining what could be done to reduce electricity bills incurred by airconditioning plants. Significant savings could be achieved in the future through the use of variable-speed drives for the plants, said Cass. Variable-speed drives for 25 ventilation fans, eight chiller plant pumps,

and eight cooling tower systems motors on all air-handling units have already been installed at the First Rand premises in Sandton. “This achieved a reduction of about 200MW, a saving of about R500 000 a year. We believe that these savings can be increased to about R2-million when other variable drives are installed at major buildings,” said Cass. Dr Steve Lennon of Eskom, managing director of Corporate Services and patron of the eta awards, said that South Africa is emerging from a period in which electricity was regarded as a cheap commodity. “Now that we have entered a phase where electricity costs are climbing, it is gratifying to see how South Africa’s major companies are working to reduce their costs. This not only saves on their operational costs, but is also a service to the country as a whole,” said Lennon. The 2010 edition of the eta Awards, marks the Awards’ 21st year in existence. Entries have already been received and the closing date for entries is 8 August. The gala awards ceremony takes place on 4 November in Johannesburg.

Make way for the
lightweight
Red Bull box cart!
All-AfricaTrussesandMiTek,roofsystemsuppliers,arebuildingaboxcartthatwillbeentered into the 2010 Red Bull Box Cart Race, which will take place on 24 September. Firhaad Khan, owner of All-Africa Trusses, says that the lightweight steel frame body of the box cart, which was suppliedbyMiTek,isoneofthefeaturesthatwillgivetheirteamthecompetitiveedgeduringtherace.
Drive it like you stole it The design of the box cart started two months ago after the vehicle plans were entered and accepted by Red Bull. “The design theme is Drive it like you stole it! ” says Khan. “Our getaway mobile is rough and tough. We didn’t try to make it slick or elegant – we call our winning box cart the Runaway Shack,” says Khan. “Our entry is a salute to people who find themselves in tough times, living in broken-down iZozos, often with empty stomachs, but they are still able to recognise the joy of life and they are able to celebrate it.” The construction of the Runaway Shack started in the middle of August. The base ladder is formed from a 25 mm2 tube that carries a light gauge steel wall frame. Light gauge steel roof trusses, complete with roofing purlins, are placed on top of this frame, perfectly imitating a miniature house. Khan explains that the technical specifications under the qualifying criteria pose the most challenges of constructing the box cart. “The box cart has to be at least 100mm above ground, no more than 3m long, no more than 1,5m wide and no taller than 2m high. The two most important criteria, however, are originality of design and a weight limit of 100kg,” says Khan. “I think a lot of people are finding the weight requirements to be quite difficult to meet. 100kg may sound like a lot, but when you take a proper brakes system, wheels, a seat and the rest of the construction into account, it is nothing,” explains Khan.
The Runaway Shack has a strong base-frame construction, lightweight 20-inch bicycle wheels, high-performance brakes, a full tie-rod adjustable steering system complete with an intricate steering wheel, number plates and a creative seat for the driver – a toilet seat! “Even though this cart is substantial in construction and features, it is still within the maximum weight limit of 100kg, due to the lightweight materials that were used,” says Khan. The team who is currently constructing the Runaway Shack is lead by Firhaad Khan and Rudolf Coetzee (a technical specialist at MiTek). “One would be hard- pressed to find a normal member of society represented in our team,” jokes Khan. “We’ve got everyone, from a German engineer to a bunch of fun younger people working on the project. We are having a great time building the Runaway Shack!” The event A variety of amateurs, gearheads and adrenaline junkies are currently constructing eccentric non-motorised carts to compete head to head in the downhill battle which will be taking place soon. This year, the Red Bull Box Cart Race will take place in Soweto and the team from All-Africa Trusses and MiTek is eagerly awaiting the arrival of the big day. “All the box carts need to travel 400m downhill, but it’s not a straight route that needs to be followed,” warns Khan. “The box carts will race down a twisted slope and there is a lane crossover halfway, which also makes the mobile’s gravity and balance extremely important.” According to Khan, the Runaway Shack has the technical specifications, precise engineering and dynamic flair that are needed to win 1st prize at this year’s event.

Cofounders of Gordon Verhoef & Krause, Earl Krause and Gordon Verhoef (left and far right) with group CEO Richard Williams and Dumisani Madi, managing director of empowerment company GVK-Siya Zama
Half a century of quality restoration 50 years ago long-time school friends Gordon Verhoef and Earl Krause decided to form a small painting and decorating business in Cape Town, which has developed over the years into becoming leading nationwide specialists in building, renovation, restoration and recycling of buildings. “Our first office was a converted garage in Hatfield Street in Cape Town and our first big job was to paint the HM Leers building in Maitland,” recalls Verhoef. In Cape Town in the 1960’s, a number of historical buildings were being demolished. Verhoef says, “These buildings were part of our national heritage. We started restoring these buildings and soon received requests to do more.” As a result, the company evolved into Gordon Verhoef and Krause Painters & Restorers (GVK), and has been responsible for the restoration of a host of major local and international landmarks such as the Union Buildings, The Castle of Good Hope, City Halls in Cape Town and Durban and numerous historic Post Office Buildings and Magistrates Courts. It has also repaired and restored countless jails, hospitals and schools in South Africa. Szerelmey, GVK’s sister company in the UK, has also carried out restorations on a number of prominent British sites such as 10 Downing
Street, Buckingham Palace and The Dorchester Hotel. In addition, the company has received a certificate from the Queen in recognition of the work done on the National History Museum in the UK as well as an award from the Duke of York for the ‘Best Restoration Job’ for the restoration of the Public Records Office. Krause says, “We started the company with nothing and built it up together. We have also endured and survived three recessions, and we trust that GVK will live on for many, many years to come. We are a family business and have adopted each of our staff members as a part of our family. Not many businesses can say that they have employees who have stuck by them for more than 30 years.” Also, GVK-Siya Zama was launched in 1994 as the empowerment initiative of the group and today contributes significantly to the success of the group. Group CEO Richard Williams says, “GVK has enjoyed continuous and steady annual growth, with turnover reaching the R700-million mark this past financial year. We ascribe this to our philosophy of constant improvement while safeguarding our principles of client service and healthy company culture,” he concludes.
