FOREWORD
issue 6 Just as we all grow, buildings also seem to be growing taller, first on paper, and eventually taking their places on Mother Earth. This means there is never a dull moment within the built environment. We plan, we design, we demolish and we build again, into the future. The questions remain, are the demolished buildings a waste of money and hard work? and, what about heritage? Is it space planning, the building just not trendy anymore? There are just so many questions that are haunting us on how, instead of demolishing a building, to rather go green and to save the planet for our next generation. “Eco-friendly” is indeed the topic of the century. I would like to thank SAIA, IID, ASAQS, ILASA and CESA for their support in being associated with TO BUILD as from this issue onwards. I am looking forward to a long term relationship and also to promoting these organisations as part of our commitment to them. I would like to extend my gratitude to Peter J Muller for his hard work as editor, and his commitment in making TO BUILD a success the last few issues. Unfortunately, due to other commitments, he cannot continue with his duty as editor of TO BUILD. It has been a pleasure working with him and we wish him all the best with his future plans. I would like to take the opportunity to introduce our new editor, Johan Schrönen, who is an individual with many years of experience in research, journalism and editing. He has a huge passion for the built environment with lots of experience, and therefore we are looking forward to having him as editor of TO BUILD, as from the next issue. He promises to carry out his responsibility as editor in a manner that will preserve and enhance the integrity of the publication. editor@tobuild.co.za I would then also like to extend a huge thanks to our regular advertisers, and our new advertisers, for seeing the value of advertising in TO BUILD. We look forward to building a strong relationship. Remember, we are here to accommodate every single client in the most honourable manner. I hope you will enjoy reading this issue of TO BUILD and please look out for our next issue which is due in November 2012.

Editor’s Note
The new Building Regulations Friend or Foe? The new Building Regulations have now been in force for more than three years, and the “Deemed to Satisfy” requirements (SANS 10400 series of documents) for a year or less, as each part is published independently. It still amazes me how much confusion there is in the industry. I do not refer only to building industry professionals, but also to building control officers. There is a definite drive by various bodies, like SAIAT and the NRCS (the governing body under which they fall), to educate the building control officers. This, however, seems to be a slow and painful process. Several councils still refuse to take Forms 1 & 2, as required by Part A, when plans are submitted, while others indicate that they are not interested in applying the new regulations. With this said, it is worth noting that, it is the built environment professional that takes the responsibility for compliance, and NOT the building control officer. During a recent meeting I had with some professionals in the built environment, it was suggested that a basic guide to council submissions be drafted, which should be applied nationally. This would not only ease the process, but also reduce the possibility of malpractice taking place. We can only hope that this situation improves rapidly, as it seems to be a thorn in the side for many professionals at this time. This is particularly so as professionals try to explain to clients that they need to comply, and the building control officers tell those same clients that it is not necessary! In this issue, we will be focussing on a few creative ideas and critical areas as far as the new building regulations are concerned. I trust you will find it informative and thought provoking.

advertorial MiTek® Nail-Plated Timber structures MiTek as the leading Roof Truss System supplier in South Africa and the world, with a network of over 140 licensed prefabricated timber roof truss manufacturers across Southern Africa, provides a competitive and economic solution to even the most complex of roofing problems. This MiTek fabricator network, using MiTek’s state-of-the-art software programs, provides high quality, purpose engineered truss units to satisfy the need of an ever increasingly complex roofing market.
Examples illustrating the diversity of application:
Residential: Ideal for all types of residential roof applications from very small to extremely large. Also especially well-suited for Attic roof applications thereby creating extra living space at a lower overall building cost, a benefit still underutilized in South Africa.
Commercial: Well suited for all types of commercial roof applications up to about 16m span, thereafter transportation can become challenging. Also especially well-suited to steep high pitched roof structures rather than low shallow pitched.
Multi-Purpose: Nail-plated timber framed structures can be utilized in so many different ways from Formwork to Seating-stands to simply exposed structures. This clearly illustrates the simplicity, beauty and strength of nail-plated timber structures.
Extra-ordinary: With special engineering input from MiTek’s own professional team of engineers it is possible to create some very large and unusual roof structures, as illustrated by these two projects: Sarela View Church using laminated timber and a 40m clear span Sports Hall.
14-15_MITEK_Advertorial.indd 14
6/25/12 9:13:05 AM
MiTek® Ultra-Span® Light gauge steel structures The low mass per m2 (between 2-10kg/m2) of this roofing system ensures both savings on the supporting structure as well as on transportation and erection costs. Large sections of the roof can simply be pre-assembled on the ground and hoisted into position on the walls – making this one of the most viable roof systems in the range of 20m to 40m clear span structures.
Examples illustrating the scope of applications:
Residential (trusses): With savings on trusses due to larger spacings added to further savings on erection due to the light weight (approx. 4kg/m2) and the convenience of no site wastage, these roof structures are ideal for low-cost housing projects with Tiled or Sheeted roofs. The roof trusses are supplied pre-assembled or in Kit-form for site assembly.
Residential (purlins): The strength and diversity of the Ultra-Span profiles make it an ideal choice for simple purlin roof applications as often found in low-cost housing. Span capabilities vary from 3m -6m with a very low mass of only 2kg/m2 of roof area. With no site wastage and all materials being galvanized, it is ideal in even remote areas.
Community: Even Church projects or other community projects with larger spans (as shown above 28m & 30m spans) for both tiled and sheeted roofs are easily managed with Ultra-Span trusses whilst maintaining the vaulted ceiling effect.
Commercial: With a proven track record of many successful applications in large clear spans (Spar-Brighton, Zambezi –Mall), Ultra-Span is one of the most economical roof structure solutions in the range from 16m -35m – this applies especially to low-pitched roofs.

Interview: Tinus Nel I recently had the opportunity to meet Tinus Nel, a structural engineer with BKS Engineers in Johannesburg. Having been involved in the Vodacom Innovation Centre, the first building in South Africa to achieve a 6 star rating from the South African Green Building Council, he is making a name for himself as a driven and ingenious engineer who focuses on interpreting a design to achieve the architect’s vision.
We find out a bit more about him and his love for engineering. ED: Tell us about your background. TN: I matriculated at Menlopark High School in 1994, where I met my wife. During my varsity years I was attracted to the structural side of engineering and did my final year thesis on Fibre Reinforced Lightweight Concrete, under the mentorship of Professor ElsabĂŠ Kearsley, who became SAICE President in 2009. Following university I joined KBK Consulting Engineers, before moving to WSP in 2004, where I was a Senior Structural Engineer till 2012. In 2012 I joined BKS, heading up the structural division in Johannesburg.

ED: Where did you study and what qualifications did you receive? TN I obtained my B.Eng degree in 1998 at the University of Pretoria and registered as a Professional Engineer. ED: What attracted you to, or, how did you get involved with structural engineering? TN: I probably designed a good dozen hotels by the time I reached 9, such was my love for architecture that I drew buildings on each piece of paper I could get my hands on. As my love for physics grew, structural engineering presented the perfect opportunity to combine architecture with physics and to leave a tangible legacy.

TN: Architects in South Africa are generally very knowledgeable when it comes to Engineering, and very accommodating. When presented with innovative ideas and new challenges, you realise again why you love your work. ED: What building is your favourite building and why? TN: I love industrial architecture of which Turbine Hall in Jeppe Street Johannesburg is a great example. After the revamp in 2009 it offers a glimpse of the old and the new. ED: On which projects have you worked? TN: I have worked on several Industrial and Commercial buildings, the highlights of which are probably The Southern Sun Hotel Hyde Park, Turbine Hall and The Pivot, in Monte Casino.

Interview
ED: You recently worked on the 6 star green star rated Vodacom campus. What was the most challenging thing, from a structural engineering point of view? TN: The Vodacom Innovation Centre allowed the consultants an almost open book to come up with sustainable and innovative ideas. Where sustainability development is conventionally more focused on the electrical, mechanical and wet service consultancy, here we had the opportunity to showcase how structural engineering can also contribute to sustainability. This included the use of reinforced earth foundations. ED: Where do you think sustainability is going towards in the near future? TN: I think sustainability will become economically more attractive. I see a bigger emphasis being placed on local sourcing and the re-use of materials. ED: Do engineers have sufficient knowledge of sustainability to give constructive input during the design development stage, especially regarding the Green Star SA requirements? TN: Sustainability is becoming very important to our clients and the larger firms are ensuring that their professionals are getting accreditation and are knowledgeable of the Green Star Requirements. ED: Are fast track projects now forcing engineers to take more aesthetic decisions regarding the design of the structural system? TN: A more sensitive approach is definitely required where the architect receives information sometimes days before it is issued for construction. A clear communication channel between the engineer and architect during development should ensure that the outcome meets the aesthetic requirements. ED:
Thank you.

Long Beach Resort, a little bit of paradise! e with thin Designmed environ ent in m d Demolishing a 333 room hotel and replacing it with one with completely modern equipment might not seem a particularly “clean” project. However, long before Long Beach saw the light of day, project design was in the hands of a very environmentally aware group of people. In Mauritius, all hotel development projects of this kind have to first obtain a special permit issued by the Ministry of the Environment and Sustainable Development. This building permit is issued after what is termed an Environmental Impact Assessment (EIA). Long Beach occupies a 59 acre site on the Belle Mare Peninsula, which is on Mauritius’ east coast. The hotel has 255 rooms, all with magnificent sea views. The architecture is resolutely contemporary but retains the charm and relaxed atmosphere of a tropical island. Indeed, Long Beach manages to combine urban elegance with a seaside atmosphere.

EDITORIAL The lifestyle has something of an Italian feel to it, with a central piazza, surrounded by restaurants, shops and bars, adjoining a 700 metre long and 40 metre wide beach. Beyond is the waters of the lagoon, crystalclear here, full of rare species of coral, just waiting to be explored. Long Beach’s architecture allies light, tropical touches to contemporary urban elegance, softened by natural shapes and typical local materials. The buildings blend in perfectly with the extensive gardens, which contain more than 500,000 plants, including 26 endemic species. In line with Sun Resorts’ environmental policy, Long Beach has taken a new approach to reducing its environmental impact to the minimum, whilst providing facilities of the highest standard. Apart from its wonderful beach, one of the most striking aspects of Long Beach is the brilliant landscaping, which has focused on the use of endemic and other tropical plants. A better way of clearing a site Normally, the demolition of the rooms and public areas of a hotel like Coco Beach would entail considerable inconvenience for its neighbours. However, during the Coco Beach’s demolition, every possible measure was taken to avoid problems linked to dust and plastering work. Thanks to the use of geotextile membranes, dampening the site and scheduling demolition work at the most appropriate time of day, the last days of Coco Beach avoided environmental disruption. The beach and the sea were similarly protected from dust pollution. As far as rubble was concerned, concrete, metal, cabling and plastic were sorted out to avoid any risk of pollution. Some of the items were sold off or recycled. Another aspect, as specified in the building schedule of works, was that the company contracted to demolish the Coco Beach was equipped with a special crusher, which meant some 20,000m3 of rubble could be crushed and part reused as infill on the site itself. This technique also led to a reduction in the materials that needed to be brought in and, at the same time, reduced the amount of earth-moving equipment required. The local authorities have commented favourably on these measures as an effective way of reducing the environmental impact on the site. Ultra green Those who have been able to follow the Long Beach project since its inception have been struck by one particular aspect of the hotel: its greenness. From the beginning, the entire architect’s design, and the images projecting the Long Beach vision, revealed lush gardens, with tropical plants blossoming across a superbly laid-out site. Today, to be convinced of the reality of these green intentions, a glance is enough to see gardeners and others bustling about every day, adding embellishing touches to Long Beach, and producing a beautiful display of trees, shrubs and flowers. Another strong environmental aspect to Long Beach is, undoubtedly, the plant nursery which adjoins the new hotel. It is, in fact, a giant of a nursery where thousands of plants are patiently waiting to be moved alongside the Long Beach bedrooms. Just before demolition work started on the Coco Beach, almost 3,400 plants were moved to the nursery. The collection of plants was well looked after and enriched with new native and other tropical species, which will form part of the new Long Beach landscape. For those who like statistics, the Long Beach has 21,000m2 of grass and 60,000m2 of bushes and shrubs. Altogether, there are 4,530 trees and palms, and 507,430 shrubs, including 26 endemic species. Even at the time of the Coco Beach, there was a botanical walkway featuring rare and endemic tree species. Long Beach will perpetuate the tradition in offering guests an exceptional natural setting. All this very special landscaping at Long Beach has been made possible thanks to the work of a busy international company, which has won awards throughout the world, Bensley Design Studios. Under the guidance of Bill Bensley and Brian Sherman, everything has been done to preserve a natural environment which fits very well with the architectural concept behind the hotel. Buildings will be perfectly integrated into the landscape. For these Eden-like gardens, the landscapers have particularly selected native and other

EDITORIAL plants suited to the Mauritian climate. For the lawns, Paspalum Notalum is very hardy, able to tolerate high levels of salt, and it provides a beautiful carpet of grass. The green approach is rounded off with plant-based herbicides and organic pesticides. Recycling and conservation At Long Beach, the watering system runs underground for environmental reasons. Water is a precious commodity and various sources will be used for daily requirements, estimated at some 350m3. For example, rainwater will be collected and stored in tanks, whilst water from the wastewater treatment plant will be UVtreated after passing through filtration systems, providing nearly 250m3 of water, which limits the need to pump water from the existing wells. All washrooms at Long Beach are equipped with flow controls to optimise the use of water without affecting guest comfort. Following the example of what has been done at Washright, the hotel group’s industrial laundry unit, an ozonation process is used on the water, which means lower washing temperatures can be used, 350°C, instead of 600°C or 800°C. Long Beach is expected to produce some 150m3 of green waste daily, some from the 59 acre site, and some compostable waste from the kitchens, which will be treated and turned into fertiliser for use on the gardens. Refuse is also sorted, using dustbins with separate sections for plastic, paper and glass that can be recycled. Sustainability The key word nowadays, for any hotel building project based on sustainable development criteria, is that of cost. Certainly there is the matter of the initial construction and equipment costs, and also maintenance over time. However, there are often positive savings that result from reduced use of resources and lower energy costs. Indeed, environmentally friendly planning can produce considerable savings when thought of in terms of quality and durability. This is the choice that the Long Beach promoters have made, starting with the Sun Resorts Board itself. Long Beach is very much a state-of-the-art hotel, using what are known as intelligent materials, the latest technology for regulating energy use, solar energy and LED lighting, and ozone and UV treatments in swimming pools, as well as recycling rubbish and waste water. Above all, however, Sun Resorts has always been a pioneer in sustainable development, as witnessed by the number of international awards and certifications the Group’s hotels have received. Managing energy use The latest macro-systems are being incorporated into the Long Beach Hotel to enable better control of energy use. Computer based Building Management Systems will facilitate the allocation, control and measurement of resources. This will automatically lead to energy savings with a reduction in the use of electricity and hydrocarbons. This centralised information system means air-control systems function depending on occupancy, and can adapt building energy use to demand. Rooms and private areas will be equipped with presence detectors, meaning that the use of lighting and air-conditioning can be better regulated. Common areas are similarly equipped. Nowadays, all green buildings need to use such technical devices. They provide automatic control of the premises and enhance the overall efficiency of energy systems. At Long Beach, considerable thought was given to the subject of lighting. In fact, before embarking on equipment purchases, designs were drawn up for the whole premises to produce a lighting plan adapted to genuine needs, for the most effective use of lighting.

EDITORIAL minimise electricity consumption. Taking this a step further, thought was also given to minimising the impact of lighting on the ecosystem, notably insects, animals, plants and birds. With its 6,000 energy efficient light bulbs, compact fluorescent light bulbs and spots or LED lighting, Long Beach is investing massively in energy saving measures. Using ten times less energy than traditional incandescent lighting, and giving out no heat, LEDs allow energy use to be kept within reason, whilst lasting two and half times as long. The saving in electricity usage at Long Beach is equivalent to the annual consumption of 500 households. Long Beach will be equipped with air-conditioning that meets the latest energy and environmental efficiency standards set by internationally recognised “Leadership in Energy and Environmental Design for Green Building Certification” organisation (LEED). These latest air-conditioners use less energy. Following the experience of Le Touessrok, Sun Resorts’ flagship hotel, in producing hot water, a system of recuperating hot water from air-conditioning cooling systems has been installed. The technique has been shown to considerably reduce energy consumption. Thermal sensor panels, a system of capturing solar energy perfectly suited to the local climate, cover a 700m2 site and will also meet some of the hotel’s hot water needs. Long Beach also has a gas boiler to back up supplies. The equipment has an automatic thermal shock system to cut out the risk of Legionnaire’s disease. Using less energy inevitably means thinking about insulation, which reduces energy consumption for airconditioning, heating and so on. All pipes carrying hot or cold fluids are insulated to avoid wasting energy. This can lead to energy savings of as much as 20%. Modern and efficient techniques have also been used to insulate Long Beach’s bedrooms and other buildings. The use of modern materials themselves, as part of the building process, means three layers of insulation can be installed. There is one noticeable feature that is by no means purely aesthetic. The roofs of buildings are covered in plants, pebbles and special materials, all of which can reduce the impact of exposure to the sun. It means that rooms remain cooler and need less air-conditioning. That is without mentioning the impact of the thousands of plants and the presence of water features, such as fountains, ponds and swimming pools, throughout the hotel, all of which cool the air temperature. The Long Beach project was managed by Mirage Leisure and Development who work in close collaboration with MLC Quantity Surveyors and SIP Project Managers. Stauch Vorster Architects Gauteng worked closely with Keith Interiors of Cape Town to create the built environment. GCC of Mauritius was the contractor for the resort.

New Building Regulations are pushing creativity! Many of the new requirements, and I refer to those contained in SANS 10400 here, have actually opened a door to enable the built environment professional to use his/ her creativity. Many built environment professionals seems to have been caught off guard by the implementation of the new Building Regulations. What adds to the uncertainty, is the fact that there is still a lot of confusion regarding the application and implementation of the revised regulations. No matter how we look at these changes, they have been published and must be complied with. But, before I venture into the body of my article, let me clarify something first. The Regulations, as published in the government gazette, are compulsory. SANS 10400 is not! SANS 10400 is only one way of satisfying the regulations, as well as the minimum requirement if another route (rational design) is followed!

With that said, the question remains to be asked, “What have the new regulations brought about?” Many of my colleagues have complained that these regulations are too restrictive and are stifling their design. I disagree. Many of the new requirements, and I refer to those contained in SANS 10400 here, have actually opened a door to enable the built environment professional to use his/her creativity. A simple example that I recently had to apply to a building I was looking at, was to introduce a light shelf into all the windows on the ground floor of a house. The particular rooms did not have second windows in them, as the building was buried and only exposed on one side. These light shelves will reflect light deep into the room, providing better day lighting levels inside. What is the reason for the light shelves? Well, to comply with the energy efficiency requirements of SANS 10400-XA. With the fenestration as it was, the building could not achieve the SHGC requirements, and it needed extended shading devices. Light shelves were the creative solution, which also addressed a different need. Awnings or canopies would have worked, but would have altered the façade totally. Similarly, SANS 10400-T now requires that any passage that forms part of an escape or an emergency route in buildings that must be designed for accessibility, must be 1500mm wide. This definitely increases the floor area of a building, but it means that a new internal environment will be created. Wider passages provide for a more user friendly environment. Users of the building will actually be able to talk to each other in passages without interrupting the movement of others.

EDITORIAL When looking at some of the requirements, as listed in SANS 10400-S, several items jump out at us. Firstly, provision of resting areas outside the line of movement on accessible routes must be provided at 25 metre intervals. Even though these are provided as resting areas for persons who need regular rest due to a physical condition, these areas can just as easily be used by occupants of buildings during breaks. Ramps are another area where the changes were quite significant. The maximum distance a ramp is allowed to rise has been reduced, as well as the maximum gradient. A further change was the inclusion of a step in the direction of travel, if the ramp runs in the same direction effectively for more than two risers. These changes now force us to consider what we do with ramps in buildings, as it can no longer just be a little add-on, on the side. The ramps should now be designed to form part of the building or the landscaping, and contribute to the overall aesthetic. Stairs are a further example. Reducing the maximum rise per stringer to 1530mm has caused various problems. Say you have two floors at 3400mm, slab to slab, then it effectively means that you will need to provide 3 stringers to get to the first floor. This could provide for a very interesting triangular shaped stair, or a zig zag staircase, which ends at an opposite end every floor – or landings mid stringer. Returning to SANS 10400-XA, roof overhangs could make a return, almost to the historical ‘highveld house’, to provide sufficient overhang to make provision for larger windows. This could provide a whole new aesthetic that could develop locally. Also, the return of smaller windows is the other alternative. Proportion of windows to wall will play a bigger role in good design. These regulation changes are not over constraining the industry. They are providing us with an opportunity to be creative and create designs that not only comply with the regulations, but also capture the imagination. How we apply the requirements is only restricted by ourselves.

Structure – The one area you should not cut corners or costs Safety in the built environment has become one of the main focus areas in recent years. One factor that is often taken for granted is the structural stability of the building. There has, however, been several building collapses that have made the news, and a closer look at what causes this might enlighten designers. There are various incidents of buildings and structures collapsing, some with no lives lost, while others were not so harmless. In May of 2004, during the early morning hours, a portion of Terminal Building 2E, at Charles de Gaulle airport collapsed. A portion of approximately 32 metres of the vaulted roof, which had been touted as a jewel of design, safety and comfort, collapsed, and tons of concrete, steel, and glass crashed down on a waiting area inside the terminal. Four people lost their lives in this incident.
In December of 2009, a staircase in a church in downtown Johannesburg collapsed, leaving 94 people injured, according to local paramedics. In September 2001, two hijacked Boeings flew into the World Trade Centre, in downtown New York. For almost an hour, WTC Tower 1 stood burning before it collapsed in an immense cloud of dust. WTC Tower 2 stood burning for over an hour before it collapsed. This tragedy, played off on live TV, to the shock and horror of millions of people worldwide. Thousands of people lost their lives in this incident. These are some examples of structural failures, with different causes. Some collapses do not lead to loss of life, but provide some level of entertainment. Who will ever forget the dancing moves of “Galloping Gertie”, or the Leaning Tower of Pisa, which is probably the slowest collapse ever?

Why do buildings collapse? The simplified answer is that the structure was not designed to withstand the forces the building had to withstand! This is an extremely simplistic description, but forms the basis of all buildings that collapse. The problem with this statement is that it is impossible to design any building for absolutely all eventualities. To clarify, we should rather look at these eventualities, which can be divided into 4 categories, namely; environmental, historic, human, and building. Before elaborating on some of these, it is worth noting that, through the South African Bureau of Standards, and the South African National Standards, a minimum standard is set for safety in design. The changes to the National Building Regulations recently now incorporate building on dolomite land into the structural standards (SANS 10400 Part B and others), to further ensure safe design. Environmental causes: Environmental causes for building collapse include, amongst other things, earthquakes, floods, tornados, tsunamis, subsidence, snow loads and fire. These incidents place excessive forces on buildings and structures, which exceed the design allowances, and therefore cause the structures to fail. In areas where these elements occur naturally, the design standards have been developed to ensure buildings and structures are designed to withstand such forces. Buildings in Japan, for example, are designed to withstand earthquakes generally, but quakes that exceed the general norm, like the one that hit Kobe in 1995, exceed the design allowances to such an extent that even buildings designed in areas allowing for them, could not withstand the forces.

Getting Started with composting “Composting is Nature’s way of recycling, and helps to reduce the amount of waste we put out for the bin men.” www.recyclenow.com Composting is a wonderful way to recycle your garden debris back into the soil. The benefits of composting are numerous. It reduces waste to landfills, cuts expenses incurred in getting rid of garden waste, reduces costs of fertilising your garden, and more. The biggest benefit is for your garden though, as it is a totally natural form of fertiliser for your garden. Compost contains beneficial bacteria necessary for plant growth, improves soil texture, and provides necessary nutrients for a healthy garden. It also assists by absorbing some moisture, keeping the soil moist, which benefits most plants. You can easily start composting at home, by using compost bins, which can be fancy or plain. To start a compost pile, first select a site in full sun, preferably sitting directly on the surface of the soil. Cut or chop garden clippings into small pieces. A mulching machine would be wonderful for this part of the job, but is not necessary. Using pruning shears works just as well. The smaller the pieces, the quicker it composts. Combining green and dry material will speed up the compost process. Using shredded newspaper when there are no dry leaves available, works as well. Keep the compost pile damp, and turn the pile often to incorporate oxygen. More frequent turning of the compost pile will produce finished compost sooner for use in the garden. When you turn the pile, you will notice the garden debris breaking down and turning black. This broken black stuff is the compost. You need to separate this from big chunks of garden waste, which you can just throw back on the pile. You can now use the separated compost in your garden, and your plants will love you. There should not be any smells associated with a compost pile, if there are, you need to ensure that the pile has sufficient oxygen by turning the pile more regularly. Smells can also be caused by a too wet pile, ie. the pile is not draining well, and there is standing water. Also avoid using food waste, especially animal waste as this tends to attract pests like rats, and could also cause smells. Lastly, during decomposition, the pile will heat up. When the composting process is complete, the pile will cool down. Avoid using unfinished compost or “hot” compost in the garden. There are many resources available on composting that you can read. The above is a basic guide to beginning composting. Remember “composting happens!”

Comprehensive Protection – with the professional touch Gareth Griffiths
“A well designed interior takes cognisance of the requirements for fire safety as required by Part T of the National Building Regulations. Further, incorporating passive and active safety systems into the building’s interior envelope has an enormous effect on the operation of the building, especially in the case of an emergency.” P Muller. “S.A. National Standard (SANS) 10400 Part T as Code of Practice affecting public and building safety aspects of the National Building Regulations, brings with it a host of compliance standards and practices for the built environment. It addresses risk management in the comprehensive sense. So, legislation for fire containment is a priority with government departments – national, provincial and local. Compliance with regulations is firmly on the agenda of many commercial and industrial companies. Leo Slootmans, CEO of fire and security service provider, FIRESPEC, says that the human factor should be a cornerstone of sustainable building practice. “Hence, the installation of best practice active and passive fire protection systems, in commercial and industrial buildings, has become key”, he says. “With the current state of the economy globally, an emphasis on existing building performance, and also on refits, is of great importance to both engineers and facilities managers. We provide the developer with the peace of mind of knowing that human safety solutions continue performing, and are in good hands, on an on-going basis. This is extremely important, since there is nothing potentially more devastating than an emergency protection system that fails to operate due to lack of testing and maintenance. We stay in touch with international trends via technology partners worldwide, and we ensure that our technicians are able to install and to service new and existing equipment to a high standard”.

EDITORIAL Historic: This is a controversial area, as this relates to quality of design and construction, as well as maintenance of the buildings and structures. Where buildings exceed the life span for which they’ve been designed, they can be in danger of failure. Even though it should not have an effect if the building was designed and constructed properly, it does seem to cause some failures. If one considers the gothic cathedrals in Europe, it is clear that a well designed and constructed building could stand the test of time. However, good maintenance forms an integral part of this survival. Timber trusses could cause collapse due to rot or termites, for example. Similarly, reinforcing steel could rust through within concrete, causing the concrete to fail. Falling Water, or rather, House Kaufman, at Bear Run, Pennsylvania, by Frank Lloyd Wright, is an example of buildings failing due to age. Even though questions have been raised regarding the structural design of the cantilever slabs from the construction period, the building did stand for an extended period. However, as the building aged, the structure deteriorated, leading to long debates about whether it should be demolished or restored. The building has been restored, but major interventions had to be done to ensure its future structural stability. Human: Human interventions causing building failures can be divided into three different areas, planned, accidental and foul play. Planned destruction, such as implosion and demolitions, cause building failures to take place in a controlled fashion. Due to the growth of population, cities and commerce, bigger buildings are required. To make allowance for this growth, existing buildings need to be demolished. Recently, Nedbank Gardens in Rosebank was imploded to make way for the expansion to the Mall of Rosebank. Similarly, various other buildings are imploded worldwide, including the Tampa Stadium, pictured below left. Accidental destruction is caused by human intervention, through negligence, or an event that was not planned. Recently, a house in Kroonstad was destroyed when a petrol tanker lost control and drove into the house in the early hours of the morning. The impact, explosion, and subsequent fire, destroyed the house Photo: http://www.dailymail.co.uk/news/ article-1258547/South-Africa-80-weddingguests-fall-lake-Dragon-Peaks-hotel.html)

EDITORIAL totally. This also includes the misuse of buildings. The various codes and standards require that buildings be designed for specific requirements, loads and forces. It further requires that a specific safety factor be included, to prevent failure of the structure under many circumstances. However, human nature does not always play according to these standards. An example of this is a pedestrian bridge, designed to allow people to walk across it, is subjected to a large group of people congregating on the bridge, exceeding the allowed design and safety factors. The bridge would fail under the excessive forces, even though it has been designed to comply with all the relevant requirements. A similar incident took place at the Dragon Peaks Hotel in KwaZulu Natal, at a wedding, as depicted on p49, lower right. A family of 80 overloaded a timber deck for a photo opportunity, and it collapsed into the water below. Lastly, foul play or terrorism. Several examples can be mentioned here. The World Trade Centre in New York, mentioned earlier in the article, is probably the best known example. Building: The last area, and probably the one where those involved in creating the built environment play the biggest role. Three areas are also included in this area, design, construction & materials. The structural design resides with the built environment professionals, who are specifically employed to perform this duty. They do the calculations and specifications to prescribe the construction requirements. Further, a requirement to inspect and sign off that the work has been done according to their design is placed on them. All of this is done in accordance with the various codes and standards. Incorrect design calculations or erroneous specifications can lead to building failures later on. During construction, several things can go wrong, which leads to sub-standard work, or this can be due to predetermined decisions to cut corners. Items that have specific impact on the structural soundness of a building include founding substrate, concrete strength, reinforcing etc. These are items than can be easily manipulated on site, cutting corners so to speak. According to reports, the staircase collapse in the church in downtown Johannesburg was caused by mounting bolts not being installed according to specifications. Material failure is the last item that can cause buildings and structures to fail. This includes using below standard materials to save costs, or materials not performing as claimed by the manufacturers. This could also be caused by various other factors, including the wrong mix ratio of concrete that is not tested for some reason. The Charles de Gaul terminal collapse, mentioned earlier on in the article, was accredited to materials failure. The above provides a general overview of the main causes of structural failure. Design, construction and materials are the only areas where the built environment professionals and contractors are involved, they are also the areas where cutting costs and corners can be done…but at what costs?

Underfloor Heating with Water
Hendrik Roux (www.homecomfort.co.za)
Underfloor heating is the most economical way of heating your home. Water based underfloor heating is widely used as an alternative to electrical underfloor heating throughout the world. The advantage of water underfloor heating, or Hydronic Heating, is that a combination of different heat sources can be used to heat up your home - from environmentally friendly solar power, to electricity or gas. We all want our homes to feel safe, warm and welcoming to our family and friends, and provide us with our place of sanctuary. Underfloor heating transforms your home environment and produces that ‘warm feeling’. At Home Comfort we do not want you to be aware of your water underfloor heating system. Our goal is to set the underfloor heating once and all you need to do is to sit back, relax and enjoy the system working for you.
History Underfloor heating has been used to heat up homes for more than 3,000 years! The first underfloor heating systems used hot air and smoke under the floors. Later, hot water was circulated under the floors. Conventional heaters vs. underfloor heating Conventional heaters use a lot of energy to superheat the air, only to send it straight to the ceiling where it cools down before descending as a cool draught around your feet. The convection effect also creates uncomfortable hot and cold spots in the room, and circulates dust and mites, potentially affecting asthma sufferers. Underfloor heating gently radiates heat from across the entire floor surface. Warm air rises slowly and creates a uniform room climate with the air slightly warmer at foot level than at head height. Because of optimal thermal positioning and better overall heat retention, comfort levels are reached at lower energy consumption rates, resulting in electricity savings of up to 40%.

EDITORIAL Water based underfloor heating is widely used as an alternative to electrical underfloor heating throughout the world. The advantage of water underfloor heating, or Hydronic Heating, is that a combination of different heat sources can be used to heat up your home, from environmentally friendly solar power, to electricity or gas.
Benefits • Safety – no electro-magnetic fields associated with electrical appliances. • Variety – choose from a number of alternative and complementary heat sources (solar, gas and electricity). • Health – the healthiest way of heating your home. • An investment – adds to the value of your property. Floor Build up:
High density polystyrene forms a great insulation below the concrete. This reduces the heat loss significantly, and should be recommended for all building projects.
Components: The components of a water underfloor heating system are; pipes, manifold, thermostats and a heat source. Pipes The pipes are built into the floor during the construction phase. The Marley PE-X pipes used are extremely tough and hard. It has an oxygen resistant layer to prevent oxygen entering the water in the pipes. The pipes have a life expectancy of 49 years.
Manifold The manifold is the control centre of the underfloor heating system. A series of valves (actuators) open and close the pipes to enable water flow to the different rooms, allowing hot water to flow there and heat up the rooms. The manifold has the following components:

EDITORIAL Outlet Manifold: The hot water is circulated through the inlet manifold, through the pipes to the outlet manifold. When one of the actuators opens a circuit, the water flows through the pipes in that room. The flow can be set by turning the valves Inlet Manifold: The inlet manifold has flow meters to indicate the flow of the hot water through the circuits. The lock nut and valve of every individual circuit must be opened to allow for flow. Actuator: The actuator is an electrical valve that opens to allow water circulation.
Ceiling Insulation: Ceiling insulation will reduce the cost of running heating costs significantly. Please contact us with a recommendation for ceiling insulation. Windows & Doors: Keep doors and windows closed to prevent heat loss. Ensure that the gaps at windows and doors are minimised to prevent heat loss.
Features Water underfloor heating has the following features: • Tried and tested technology internationally. • Integrated to the water heating system for your home • Efficient – installed in the screed during the building process to ensure that the energy is stored for maximum efficiency. • Cost saving – the most economical way of heating your home. • Environmentally friendly (if powered by solar energy). • 10-year warranty. • Compliance – IEC, ISO 9001

EDITORIAL Layout of the pipes in the room: One of 3 options is available for the layout of the pipes:
Suitable for any floor type Home Comfort underfloor heating can be installed under any kind of flooring material: • Carpet • Tile • Wood • Concrete The electronic thermostats can be locked to never exceed a certain floor temperature – an important feature for certain types of wooden flooring where the manufacturer’s specified maximum temperature may not be exceeded.
Intelligent, programmable thermostats While most other thermostats only switch the heat on and off, intelligent thermostats allow you to set different preferred temperatures for different times of the day. The system is equipped with temperature sensors in the floor and higher up in the room. You just “set and forget” and the intelligent timer/thermostat will automatically maintain your selected comfort levels at all times, irrespective of the outside temperature.

Improve Energy Efficiency for Buildings By Using Wooden Windows Christine Anderssen (www.kparkerjoinery.co.za)
It is generally accepted that the majority of houses in South Africa are energy inefficient as they are not designed or constructed to maximise energy efficiency. It is recognised by the government that we need to become an energy aware society. To this end, legislation is being planned to encourage architects and builders to consider energy efficiency in their designs in future. Building regulations in South Africa are under review with the need to reduce energy demand from industry by 15% by 2015. Standards South Africa has been working on two performance standards SANS 283 and 204, in which standards are being prescribed for all naturally and mechanically ventilated buildings. Energy efficient windows are a particular focus so that contractors and homeowners will have a guide for the planning and design of their development. The Australian building code has been used as an example because their standards relate to similar climatic conditions that we find in South Africa.

EDITORIAL South Africa has been divided into six energy usage zones, dependent upon climatic conditions. They are described as: 1. Cold Interior 2. Temperate Interior 3. Hot Interior 4. Temperate Coastal 5. Sub-Tropical Coastal 6. Arid Interior.
Energy performance ratings for windows have been established for climatic conditions in numerous countries, including the USA, most European countries, and Australasia. A Label is affixed to a product to indicate the energy efficiency ratings. The main factors for which ratings have been decided in these countries are: 1. The U-factor. Expressed as U-value. The rate at which heat is lost from a building. The lower the value the better. 2. The R-value. This relates to how well the window insulates the building and restricts heat transfer. The higher the value, the more effective the insulation in resisting heat flow into the building in summer and out of it in winter. 3. SHGC. Solar heat gain co-efficient. This indicates how well a product blocks heat from the sun. The lower the number, the better. A low SHGC means the window transmits less solar heat.

EDITORIAL 4. Visible transmittance refers to visible light being transmitted. The higher the VT, the more light is transmitted. 5. Air leakage. Heat loss and gain occur by infiltration of air through the cracks in the window assembly. The lower the AL, the better. 6. Condensation resistance. This measures the ability of a product to resist the formation of condensation on the interior surface of that product
Energy efficiency ratings are country specific It is important that the above ratings are country specific and so a facility is being built to test South African products and determine the coefficients for South African climatic conditions and the six energy usage zones.
Timber Windows Performance Ratings The ratings for timber windows internationally are better than those for metal or PVC windows and are recommended by the WWF as timber windows require less energy, are more efficient, and less CO2 is emitted into the atmosphere in their production. Energy Efficient Building Design Principles: 1. Design for climate as per the energy usage zones and climatic conditions. 2. Insulated walls, ceilings, windows and doors increase overall insulation levels. 3. Consider building orientation, have main living area windows to the north (if in the southern hemisphere). 4. Position windows to allow cross breezes to ventilate rooms naturally. 5. A light coloured roof reduces the flow of heat from solar radiation better than a dark roof. K Parker Joinery is one of the premier manufacturers of quality wooden sliding doors, folding doors and pivot doors in South Africa

The case for switching to LED lighting Introduction of LED lighting technology offers South African businesses an estimated annual collective energy saving of R41 million, while offering great quality light to create better work environments and ambience in hotels, offices and shops.
We have now reached a tipping point in the development of high quality Light Emitting Diodes (LEDs) where this exciting new technology can now be used for general lighting in almost all applications. This is good news for planet earth, and its people, because quality LEDs offer solutions to some of the key issues and opportunities we face today – the energy crisis, climate change, resource scarcity, safety in our cities, productivity in our offices, and an enhanced sense of health and well-being, to name but a few. Nor should we forget that LED technology, when combined with the latest solar and battery developments, can also provide practical light for the third of earth’s population who currently live without electricity. These benefits are of course derived from the extraordinary characteristics of good quality LEDs. Today, LED lighting can deliver very high energy efficiency, long life, and excellent quality of light, design flexibility, controllability and colour – all of which are essential to creating solutions which will improve lighting. And the worlds lighting markets are now starting to embrace the new technology. Philips, the world’s leading lighting company, now predicts that by 2020 about 75% of the global lighting market will be LED based, a figure derived from both current sales data and its thoughts around future trends. But this still leaves a huge

installed base of much older, less efficient lighting solutions which are a considerable and unnecessary drain on our resources. The facts and figures supporting a rapid switch to LED lighting are these: Lighting currently consumes an average of 19% of global electricity production, and the great majority of this current lighting is based on older, less efficient technologies developed before 1970. A full switch to the latest LED lighting would provide very significant energy savings of up to 80% in many applications, and an average of 40% for all lighting. This equates to approx 130 billion euros per year in running costs, or 670 million tons of carbon, or the equivalent output of 640 medium sized power plants. In most cases, it is a simple switch to make, and it should also be noted that more than three quarters of all lighting is in the commercial and industrial world rather than the home. Many global initiatives are currently being taken, by companies, governments and NGOs, to speed up the rate of switch. The rate of adoption will also depend on other factors, such as further cost price reductions, the speed of investment and, basically, how persuasive the higher quality end of the lighting industry is in creating awareness and getting the world to switch. There is a cool, almost magical, feel to quality LED solutions – tests have shown that people prefer the light, even when, in the past, the quality could still be demonstrated by conventional measurement to be less than conventional sources. They also represent the digital 21st century and will play a significant role in helping to solve some of the key issues and opportunities we face today.

Verosol is a worldwide supplier of branded quality solutions for solar control, and Aluglass is the license-holder for these sun-blinds in southern Africa. These sun-blinds ensure effective protection from heat and reduction of irritating and bright sunlight while retaining a perfect view of the outside world. Combine the advantages of curtains and external sun-blinds in a single product, safely fitted to the interior wall, with these sun-blinds.
EnviroScreen.
Sustainable solar control: the greener blind. EnviroScreen is a highly reflective, robust, transparent, metallised fabric, which provides visual and thermal comfort. It is woven in a screen-like construction, but with a clear textile appearance, suitable for roller blinds and panel tracks. Thanks to the high reflectivity, EnviroScreen lowers heating-and cooling costs substantially. This results in a reduction of CO2 emissions, and therefore minimises the greenhouse effect. EnviroScreen is available in 2 transparencies, 2% and 10% openness factor (OF). Even with the 2% OF, EnviroScreen allows a very good view through,suitable for all fenestrations and all elevations, worldwide.
SilverScreen can also be called a green product! SilverScreen is produced environmentally friendly, it has the Öko-Tex Standard 100 certificate and is formaldehyde free. This means that SilverScreen does not contain any harm causing elements for our health. Besides, during the summer SilverScreen keeps the warmth outside, due to the reflecting metal layer and it will reduce the loss of warmth during the winter. This results in considerable savings on the costs of energy (airconditioning, heating etc.), but it also reduces the amount of CO²-emissions.

Flow restrictors are an easy way to save water With water being targeted as the next part of sustainable regulations through Part XB, as mentioned by the National Regulator for Compulsory Specifications, reducing our water consumption is becoming more important. Flow restrictors are an easy way to save water. There are several different types available, depending on the equipment they are to be used with. Most of the sanitaryware manufacturers now provide them as standard, with a variety of their fittings. They also supply a range of loose flow restrictors, specifically designed to fit onto existing bathroom taps, kitchen taps and showers. Flow restrictors operate in one of three ways. The first type, an aerator, introduces air into the water, which gives it a light fluffy flow, which slows down the volume of water consumed. These replace the flow straightener, which is in the end of a mixer tap spout. The second type, a flow regulator, fits before the device on the pipe work or, in the base of the tap itself. These are designed to reduce the flow of water by restricting the size of the supply ‘pipe’. The third type, a spray unit, reduces the water by restricting water flow to a spray. Showers: Cape Town has already introduced new water by-laws that restrict water usage. In terms of the new water by-law, the maximum flow rate from any showerhead may not exceed 10 litres per minute. The average shower uses about 22 litres of water per minute. By using a ’low-flow’ showerhead, the water consumption can be reduced to less than half this amount. This is, however, obsolete if you take extended showers.
A variety of fittings that are available to install on existing fittings.

EDITORIAL These low-flow showerheads restrict the amount of water that flows out of a showerhead under pressure. Water travels through an opening of about 5 mm and is forced into a small turbulence chamber where it is broken up into millions of tiny droplets. This saves up to 50% of the water. This water saving also reduces the amount of electricity used for heating water. It should be noted that this system might require a certain water pressure to allow for the successful operation of the shower system.

New generation tap with aerator
Basins: Tap aerators can be fitted onto bathroom and kitchen taps, reducing normal tap flow from around 20 or 30 litres per minute, to a more sensible 6 to 10 litres. Cape Town’s by-laws restrict water to taps to a maximum of 6 litres per minute. These low-flow devices basically work by channelling water through a small screen that is screwed onto tap openings. Water is restricted through a 5 mm opening and air bubbles are added for a pleasant, splash-free, bubbly stream of water. This also causes soap to lather better. Water-flow from your tap can be reduced by 50% to 75%, while the water pressure remains the same. Similar to showers, the water pressure might affect the operation of these aerators. Depending on the taps you have, aerators should screw into taps easily. Some taps might, however, require a thread adaptor to fit these, while other, older taps might require a total replacement.

Lonza Wood Protection announces improvements to its Guarantee Programme As part of a long standing commitment to offer ‘peace-of-mind’ after-sale assurance to customers, Lonza Wood Protection has announced improvements to their Wood Preservative Treatment Guarantee Programme, making it the most comprehensive and only guarantee of its kind in South Africa. Since the initial launch in 2002, the guarantee has built confidence in the exceptional durability of Tanalised™ and Vacsol™ preservative treated wood products against insect attack and wood decay. The Treatment Guarantee covers attack from wood-borer, termites and wood decay on poles and timber treated with Lonza’s Tanalith™ and Vacsol™ wood preservative products. The guarantee periods range from 15 to 50 years depending on the wood preservative product, and the end-use application. “The improvements to our Wood Preservative Treatment Guarantee Programme have come into effect in respect of external market factors pertaining to certain SANS 457 (treated pole) specifications, and the impact of the new Consumer Protection Act legislation. The improvements also make provision for the implementation of stricter control measures to ensure full compliance with the guarantee terms and conditions,” said Gerard Busse, Marketing Manager at Lonza Wood Protection. To meet the compliancy requirements of the new Consumer Protection Act, Lonza has introduced a userfriendly online customer registration facility, which can be accessed by logging onto www.tanalised.com/sa/ Products/guarantee.htm. Upon verification, Lonza will issue a written confirmation of acceptance, making the guarantee valid and enforceable. It is important to note that the guarantee can be transferred from one owner to the next, and that it is a replacement guarantee and does not cover consequential damage. ”The website also contains a comprehensive listing of all our accredited treaters and their locations, to provide any purchaser with an ‘easy-to-access’ point of reference. Simultaneously, this provides a platform for us to re-enforce the message that the improved guarantee programme only covers wood treated by an accredited Treater. This updated, and more comprehensive, version of the guarantee reiterates our commitment to adding value to our products, through service and support that is second to none,” concluded Busse.
For further information and the full terms and conditions of the improved Wood Preservative Treatment Guarantee, please visit the website at www.tanalised.com/sa/Products/guarantee.htm www.tobuild.co.za

Lonza Wood Protection meets the emerging demand for ‘green’ rated products “The growing awareness surrounding carbon emissions and resource depletion and efficiency has become a major consideration when comparing timber to alternative products.” Busse
In an affirmative step towards embracing a modern, compliant product range, Lonza Wood Protection has received the Ecospecifier Global endorsement for two of its products, namely Tanalised™ E, and Vacsol™ Azure™ preservative treated wood. This sets the foundation for Lonza to meet the noticeable shift towards an emerging awareness by industry professionals and the end–user for alternative contemporary products that bear the environmental Green Star rating standards. “Right now the end-user is looking for more environmentally sensitive wood treatments that will assist in good green design practice and meet growing public and private demand. As an industry, we need to encourage professionals to use more timber, which reduces the carbon footprint of buildings, increases thermal efficiency, offers great aesthetics and structural strength, and is sustainable and renewable,” said Gerard Busse, Marketing Manager, Lonza Wood Protection. The recent launch of Vacsol™ Azure™ preservative, sets the product apart from previous solvent borne treatment products by being the first metal-free, light organic solvent wood preservative in the South African

EDITORIAL market. Being verified as an Ecospecifier Global product, it is rated among the contributing products to the achievement of the Green Building rating tool credits. The assessment was done following Ecospecifier’s thorough scientific assessment using a Life Cycle Thinking (LCT) analysis in combination with a health and eco-toxicity screening. This tri-functional wood preservative contains advanced organic azole fungicides and a synthetic pyrethroid as an insecticide / termiticide for the effective protection of timber against fungal decay, woodborers and insect attack. Pressure treated timber that has been impregnated with Vacsol™ Azure™ preservative, a Light Organic Solvent Based Product (LOSP), provides greater dimensional stability than conventional water borne wood preservative products, and is ideal for interior cladding, laminated beams, as well as moulded and engineered wood products. Being metal-free and ultimately biodegradable, Vacsol™ Azure™ preservative is a far more suitable product than previous, tin-based, solvent treatment products, such as TBTN and TBTO-Lindane. “The growing awareness surrounding carbon emissions and resource depletion and efficiency has become a major consideration when comparing timber to alternative products. Compared to untreated wood, Vacsol™ Azure™ preservative prolongs the life of timber structures, thereby bringing about a substantial saving in energy costs resulting from harvesting, milling and further secondary processing. In support of the prevention of biodiversity damaging practices, the timber used at this stage is all abundant and renewable resources from South African pine plantations, of which many are certified under the Forestry Stewardship Council,” adds Busse. Vacsol™ Azure™ treated wood is designed for use in low to medium risk, H2 interior, above-ground hazard applications such as roof trusses, framing, flooring, ceiling and skirting, and selected H3 exterior above-ground applications. The preservation solution is a clear, amber coloured liquid, and on application transforms wood to a light honey shade. All H2 Hazard Class above-ground applications carry a 25-year Limited Treatment Guarantee by Lonza Wood Protection (see the full terms and conditions at http://www. tanalised.com/sa/Products/guarantee.htm). Vacsol™ Azure™ preservative will initially be introduced through the following treatment plants: D & A Timbers and Lamtim in KwaZulu-Natal, and Airton Timbers and Timber Preservation Services in the Western Cape. Similarly, the Green Star certification of Tanalised™ E pressure treated wood puts it in a good position to provide professionals with additional options in specifying treated wood products. Also sourced from Forest Stewardship Council (FSC) certified plantations, Tanalith™ E is based on a copper azole based formulation that provides protection against termites, fungal decay, soft rots and insect borers. It is suited to residential and commercial applications, such as structural and decorative timber products for both indoor and outdoor applications. Internationally, Tanalith™ E has been widely and safely used for many years, and similar applications for the product are emerging locally by clients such as the Endangered Wildlife Trust (Johannesburg Zoo). Busse concluded, “The Ecospecifier Global endorsement of our Tanalised™ E and Vacsol™ Azure™ products is a clear indication of Lonza’s stance and commitment to providing solutions that not only meet the Green Building rating tools, but are also focused on achieving a sustainable future for future generations to enjoy.”

Stairs built to last A bold step, by a local architect, in addressing an area that always turns into a maintenance nightmare. When you visit Europe, and especially the older towns, you will encounter solid stone stairs and walkways. They have been there for hundreds of years. On the opposite side of the spectrum, you find modern buildings, with tiled staircases, and, inevitably, you will find some maintenance work being done, replacing cracked tiles or fixing tiles that have come loose.
In a bold approach by a local architect, an external staircase detail was developed to reduce this maintenance issue, which always seems to distract from the appeal of any building. The detail calls for a solid granite stone piece, as indicated below, which might be seen as calling for more natural resources (and therefore being a less sustainable option), but, over the lifespan of the staircase, repeated maintenance and replacement of tiles requires more resources. Contrasting stair nosing is achieved by different finishes on the stone. It also requires less precise cutting, as only two sides of the granite block need to be cut. Most sustainable interventions currently incur additional costs, and this staircase will be no exception. When looking at the life expectancy of a stone staircase of this nature, the building it serves may be long gone, and the staircase will still be around.

Add some colour to your life
Colour is something that many people overlook when considering home improvement ideas. Focus is usually put on replacing appliances, or other big ticket items, when the term home improvement is used. Colour is truly very important though, and can very easily change or modify the entire atmosphere of a particular room. One of the easiest ways to add colour to a room is by painting the walls. The hue you use should partially depend on the room you are painting. White paint works for any room and can add a fresh clean feel to the room you are painting. For a lot of people though, white equals boring. So don’t be afraid to get creative. As a general rule, stay away from dark colours in small rooms. But, if you are feeling gutsy, and love dark, rich colours, try painting just one wall in the room with that colour and then finding items to decorate the rest of

the room in that same colour family. Don’t fall victim to any pre-conceived notions about which rooms should be which colour. Pick your favourite colours and if you can’t decide, pick them out of a hat to designate which room will be which colour! There are lots of opportunities to add colour in your home besides just paint. Carpeting can quickly change the entire feel of a room. Red, green or even purple carpeting can add a distinctive and funky flair to a room. Sometimes carpeting can be expensive, and you may want a cheaper option like a rug. A sufficiently sized rug can achieve a similar effect, and it also has the versatility to be moved if necessary. Rugs often work best in smaller rooms like dens or offices.

Another great way to use colour in home improvement is with drapes. Drapes take up a large portion of a wall, so what colour they are has a sizable impact on the room’s overall impression. You can match the colour of the drapes with the furniture to give the room a cosy feel or have them be at the opposite end of the spectrum to have an interesting sense of contrast. Sometimes there is absolutely nothing better than a little natural colour. For home improvement, consider adding some plants to your dwelling. Even a single potted plant can really add some green to an area. For some more diverse colours, consider flowers. Plants can be at almost any height and you can have them at ground level, put them on platforms, or even hang them from the ceiling. Colour plays a crucial role in home improvement. Beyond the basics of painting you have many options to change how your home looks. Carpets and rugs will probably have the next biggest visual impact on a room. Curtains matter a lot as well and their colour can change a room significantly. For a more ‘down to earth look’, consider adding some plants or flowers. Any way you go, don’t be afraid to add colour. You’ll be surprised at the result!

Corobrik: Building Sustainability with Bricks and Mortar Peter Kidger
When it comes to addressing sustainability issues facing South Africa, few building materials can compare with (or match up to) clay brick’s considerable basket of intrinsic benefits. Residential farming estate built on a rehabilitated quarry
Corobrik is taking these benefits a little further, conducting its business strictly within a sustainable development framework, addressing today’s sustainability imperative in all three dimensions – economic, social and environmental: • I SO 9001: 2008 Factory Management System certification is well advanced at all Corobrik factories, with six factories having been certified. • Environmental Management Plans exist for each quarry and process, this includes concurrent rehabilitation to minimise rehabilitation liabilities, and the final rehabilitation of worked out quarries as farm lands and/ or urban land for further economic use. • The use of proven technologies, international best practice, and extensive product development and testing by Corobrik’s ISO IEC 17025 certified Central Laboratory, assures product quality, consistency and attributes that are ahead of recognised industry standards and norms. • Successful dematerialisation through the use of new extrusion technology that has reduced the embodied energy of our face brick by up to 20%, when compared to standard 3 core-hole bricks. • The wider use of cleaner burning fuels and energy usage efficiencies. Natural gas, as used at six major Corobrik factories, has reduced the CO2 emissions for every gigajoule of energy by some 42%. • The pursuit and achievement of ISO 14001 Environmental Management certification, with all current ISO 9001:2008 certified operations committed to achieving ISO 14001 certification during 2012. • The continuous focus on the well being of ecosystems around Corobrik operations.

• T he recycling of brick production waste back into brick making processes, or as aggregate for concrete product manufacture. • Where possible, the use of waste streams from non brick making processes,to close the waste loops in the broader industrial ecology. • Involvement with local economic development projects at all Corobrik factories designed to create sustainable employment and uplift surrounding communities. • Empowerment through education, training and skills development that includes the annual issuing of both internal and external bursaries. • The funding of Corobrik Building Training Centres to develop and perfect skills in bricklaying, block laying and paving. Consequent to the above, Corobrik is able to bring to the market bricks of the highest quality with carbon footprints in line with international best practice for the technologies and firing fuels Corobrik employs. These attributes add further value to the substantive generic environmental attributes alluded to, and as defined by: • T he inorganic and inert mineral properties of fired clay that are recognised as meeting all necessary requirements for “healthy living”. • The inert qualities of fired clay that release no VOC’s or toxic fumes to impinge on air quality under any condition. • The material’s extreme durability that mitigates future carbon debt associated with refurbishment and replacement of less durable materials. • Maintenance free qualities, as a face brick, that mitigate future carbon debt associated with a life time of maintenance. • The reusability of demolished brick as masonry or paving brick and/or recyclability as aggregate for road making and concrete product manufacture. • The inherent thermal mass of clay brick that is fundamental to Passive Solar Design and the cost effective operation of buildings, with nature in mind.

Corobrik Pavers complete The Umhlanga Promenade Shirley Williams
Corobrik has, once again, played an important part in the final phase of the Umhlanga promenade upgrade, with its clay pavers being a defining characteristic of the entire 5km long seafront stretch that is already a favourite with those out for a morning stroll, jogging or taking a late afternoon walk with their dogs. Mike Ingram, sales director for Corobrik, said the swirl pattern and use of Cederburg, Champagne and Burgundy pavers had been taken through all four phases of the project. This continuity along the entire promenade included the design which emanated from the iconic whale bone pier, and echoed the unique seafront location with its dunes and breaking waves. The choice of colours and texture perfectly complements the landscape. The Umhlanga beachfront promenade upgrade, which cost approximately R70 million, was in the process of being designed when extreme weather conditions, in March 2007, severely damaged much of the beachfront infrastructure. This accelerated the project forward. It was also the ideal preparation for the 2010 Soccer World Cup. Construction of the final phases of the development indicated a longer term approach to promoting Umhlanga as a prime tourism destination within the ambit of eThekwini. The fourth and final phase of the upgrade began in January 2011 and finished in December. The project was funded by eThekwini Municipality’s Economic Development Department and was a combined initiative with a collaborative team from the City’s Architecture Department –Urban Design & Landscape Architecture Branch, Engineering Unit’s - Development Engineering Northern Branch and Electricity Unit’s – Special Lighting Branch. In addition to the building of retaining walls to hold the walkways in the event of further storms and landscaping, the municipality elected to replace the existing concrete block paving with, more aesthetically pleasing, clay pavers. However, according to Ingram, the choice of clay pavers went far beyond the overall look of the promenade. “Corobrik clay pavers were the practical choice. They are extremely durable and are skid resistant, making them the perfect choice for an area which is exposed to harsh weather and sea spray, and they are specially created to handle high volumes of pedestrian traffic.” Ingram added that Corobrik pavers were also suitable for long-term maintenance as they do not fade and can be matched to new pavers. They can be easily lifted or ”unzipped” to gain access to underground services. Replacing the pavers leaves no “scar”.

Roofing and Sans 10400-Xa:2011 – Pitching For Greater Energy-Efficiency
David Beer
As from November last year, roofing on South African buildings will have to be considerably more energy-efficient. Building regulations have recently undergone major revision, the aim being to introduce much greater energy-efficiency into all construction materials and processes. It was an initiative driven by the Department of Trade and Industry (DTI), through the NRCS (National Regulator of Compulsory Standards). Roofing materials and systems constitute one of the areas covered by new energy-efficient regulation, SANS 10400-XA:2011, which is largely based on the voluntary energy-efficiency standard SANS 204:2011. Published by the SABS in August last year, SANS 10400-XA:2011 became mandatory in November of last year.

EDITORIAL Concrete roof tiles, as used in the hot box test.
SANS 10400-XA:2011 requires that, irrespective of material composition, roofs must be built to maintain thermal resistance (R) values of between 2,7 and 3,7, depending on the climatic region in which they are located. Thermal resistance is the measurement which determines how various materials, in this instance roofing materials, prevent internal temperatures from rising too fast and becoming excessively hot, or from dropping too quickly and becoming uncomfortably cold. Roofs and roofing structures form just one element of a building’s total thermal resistance capacity. Other elements include; masonry, flooring, windows/curtains, and doors. “What the new regulations mean, for the construction industry and property developers, is that most forms of roofing are going to need much better thermal resistance, and this is likely to be achieved through the addition of various types of insulation material,” comments Laing. Table F.3 of SANS 204:2011 lists various materials and elements which make up the total thermal resistance of a roofing system. Thermal resistance is measured in m2.k/w and is described as an R value. ”The CMA is concerned that the R value for concrete roof tiles, quoted in SANS 204:2011, was only 0,02, compared to 0,00 for metal cladding. Although we assumed metal cladding had no thermal resistance, logic told us that the R value for concrete roof tiles must be greater than 0,02,” comments Laing. In an attempt to prove this, the CMA commissioned the AAAMSA Group to compare the thermal performance of a metal-cladding roofing system to its concrete roof tile equivalent, using South Africa’s first “Hot Box” apparatus, operated by TTL in Pretoria. The tests were based on “Cathedral Ceiling” roofing systems, using 8mm gypsum board. Temperature movement was upwards and outside wind velocity was 5.5m/s. The surface-to-surface R values yielded from the Hot Box tests were 0.2 for the metal cladding, and 0.32 for the concrete roof tile. To get the actual R value of the roofing material, the 0,05 R value of the 8mm gypsum and the 0,16 R value of the air space should be subtracted.

R value metal cladding = 0.20 – 0.21 ≈ 0.00 R value concrete roof tile = 0.32 – 0.21 ≈ 0.20 (10 times higher than the quoted 0,02)
The following table isolates the various contributions to the thermal resistance in a basic metal-clad roof on wooden beams with no ceiling (typical of government subsidy houses a few years back).
Just by adding a ceiling one achieves an increase in thermal efficiency, not only from the ceiling itself, but, more importantly, from the air space between the metal cladding and the ceiling.
The CMA has always stated that a ceiling is very important. Besides its aesthetic dimension, it improves thermal efficiency by a considerable margin. Adding concrete roof tiles simply makes the system that much better.

“It is the addition of a ceiling which enhances the thermal resistance of both materials considerably, i.e. from 0,24 to 0,34 depending on the direction of the temperature movement,” says Laing. However, he points out that when one goes to the expense of assembling additional rafters for the inclusion of a ceiling, it makes sense to use concrete roof tiles rather than metal cladding. “Concrete tiles cost no more than metal sheeting. Where metal roofs can save on capital outlay is in a lower roof-frame requirement when no ceiling is included. However, living under a metal roof with no ceiling is not much better than occupying an oven or a freezer, depending on external ambient temperatures. “Besides providing greater thermal resistance than metal, concrete roof tiles offer other benefits such as a very low maintenance requirement and better aesthetic properties. Furthermore, what SANS 204 and SANS 10400-XA have not taken into account at this stage is thermal mass, namely the capacity to store heat much like a battery stores power. “The CMA is continuing its research in this area with the aim of proving that roof systems incorporating heavy roof claddings, such as concrete roof tiles, might require a lower total R-value compared to lighter materials. A similar theory is used to differentiate between masonry walls and lightweight construction methods. Research is also being conducted as to what degree thermal mass adds to overall thermal efficiency and, once completed, is likely to prove that it makes a substantial contribution,” concludes Laing.

Pspc announces plans to use recycled eps in low cost housing building initiatives Recycled EPS provides much needed insulation and diverts valuable material away from landfills. Two of South Africa’s most pressing needs, namely the need for sustainable, low cost housing, and the need to divert recyclable materials away from the country’s landfill sites, which are rapidly approaching their fill capacity, have found an unlikely common solution in recycled expanded polystyrene (EPS). Until recently, the Polystyrene Packaging Council (PSPC) has been struggling to develop markets for used, post-consumer polystyrene. “One of the biggest headaches we faced when talking to recycling companies and converters, was the need to wash and dry the contaminated polystyrene – typically used in the manufacture of take-away hamburger clamshells or disposable coffee cups or food trays”, explains PSPC Director Adri Spangenberg. “However, the high cost of electricity and water in our country did not make it a viable financial option for smaller recycling plants to invest in infrastructure that would mechanise this entire process, resulting in much of the used polystyrene either being sent to landfills or exported to countries such as China and India for recycling. Thanks to research, design and development that has been done by Tower Technologies at the CSIR, first series or demonstration homes have already been built and undergone extensive testing, yielding positive results all around. The size of the standard two bedroom house being built is 26 m2 and weighs 1.6 tons. It contains 5 % EPS regrind (which equates to 75 kgs), which is thoroughly mixed with concrete to form walls that are almost indestructible. “As a result of the breakthrough technology and applications developed by Tower Technologies, we will be in a position to harness the fantastic insulation properties and other characteristics that make polystyrene a unique low cost housing construction project material. Thanks to the fact that there is a readily available stream of used EPS in our country, we are able to provide more than enough material for the pilot phase of this initiative, which will see many low cost homes being built around the country.
For more information about the project, please contact Adri Spangenberg at the Polystyrene Packaging Council on (012) 259-0554 or (082) 686-5082.

CORPORATE PROFILE Core to the BlueScope Steel ethos is the principle of sustainability, which manifests itself in an impressive line-up of products made to last the life of the building, and beyond. Among these are iconic world firsts such as ZINCALUME® steel, and Clean COLORBOND™ steel, which is coated with in house designed super polyester paint systems. Wayne Miller, the company’s head of operations in Southern Africa explains that the approach has been to “educate and inform the local market on the advantages of working with sustainable products that equally provide long life under a wide range of African climates, and provide beautiful, aesthetically pleasing roofs that improve property values wherever they are applied”. A number of architects and other built environment
practitioners have attended the BlueScope Steel sponsored lectures where leading sustainability architects are brought to South Africa to share their knowledge. This includes the 2011 tour by Peter Stutchbury of PSA in New South Wales. “Stutchbury’s tour appealed to packed audiences nation-wide, and forms part of an ongoing programme to provide the market with up to the minute global green building trends”, says Wayne Miller.

steel is aluminium/zinc coated steel – based on a coating of 55% Aluminium, 43.5% Zinc and 1.5% Silicon. In the South African market, lightweight, easily formable steel substrates are available coated to either 150 gsm AZ coating (AZ150) or 200 gsm coating (AZ200). Flagship product, Clean COLORBOND™ steel, has the ability to keep roofs cooler. This is maintained by using a specially developed infrared technology coating to reflect heat away from the roof surface, significantly, this also applies to the darker colours. Clean COLORBOND™ steel supports longer lasting buildings by means of enhanced chalk resistance properties, that offer a higher resistance level to paint breakdown, typical to hot climates. The gloss-retention coat protects the sheen of the brand new roof, and keeps it in a pristine condition for longer. ”We are frequently called on to inspect and advise on replacement roofing country-wide, where fading has occurred to the point that total replacement is necessary to ensure future longevity”, says Miller

South Africa’s Standardisation and Quality Assurance service provider of choice. As South Africa strives to grow the economy, create jobs to alleviate poverty, and limit environmental impact. The SABS is set to play an important role, and has the ability to face these challenges: • 6 6 years of accumulated standardisation and conformity assessment experience • Visionary leadership • 150 accomplished Test Auditors • 350 qualified Test Officers • A new leading-edge laboratory complex completed in 2011; and • A footprint that covers South Africa and extends way beyond its borders.
Markets, business models and the climate may all be changing, but our mission remains; to enable efficient functioning of the economy and the environment, through standardisation and quality assurances. The SABS is a statutory body that was established in terms of the Standards Act, 1945 (Act No. 24 of 1945), and continues to operate in terms of the latest edition of the Standards Act, 2008 (Act No. 29 of 2008), as the national institution for the promotion and maintenance of standardisation and quality in connection with commodities and the rendering of services.
SABS Standards Division It is of paramount importance for South Africa to create a competitive industry that will keep pace with the fast changing face of the world economy, where globalisation, increased competition and technological innovation have become the new parameters to drive economic progress, sustainability and employment for its citizens. The role of SABS Standards is to develop and maintain relevant South African National Standards (SANS) and other normative documents to support this. During 2010, a detailed study was done to benchmark the SABS with other national standards bodies. It revealed that the business model needed to be reassessed in order to improve its ability to deliver appropriate standardisation solutions for South Africa. The analysis has resulted in the division’s development of a strategy which will enable the organisation to play a more pivotal role in the following areas: • E xpanding International Trade: South Africa’s prosperity depends on international

Corporate profile create efficiencies in all sectors of the economy. These efficiencies will support the government’s economic development plans. • Supporting a Green Economy: The reduction of greenhouse gas emissions is pertinent on the country’s agenda. The development of South African National Standards to support this initiative is high on the agenda of SABS Standards. Green businesses require standards to participate in the global supply chain – creating confidence that we, as a country, are striving towards a green economy. SABS Standards identified five key objectives to achieve our vision of becoming the trusted standardisation and quality assurance provider of choice. • Develop and maintain market relevant national standards that support the competitiveness of the South African Industry and facilitate the protection of health, safety and the environment. A clear message must be communicated on the value-add of standards.
• Maintain a transparent and impartial standard development process that promotes wider participation for all sectors of industry. • Acquire and develop skills through the introduction of sector specialists and strengthening the expertise within technical committees. The SABS will focus on the broadening of the pool of experts available to improve the sustainability of technical committees. • Expand the understanding, recognition and use of SANS, by partnering with a wide stakeholder base in order to promote the value of standards and the idea that standards are effective tools in the implementation of public policies and good governance. • Maintain and increase our regional and international standardisation influence in promoting South Africa’s views and interests in standards development. SABS Standards is committed to delivering on Government interventions and policies such as IPAP II.
Building & Construction SABS is a leading business services provider to organisations worldwide, offering a range of services for management system certification, product testing and certification, and standardisation. This includes the standardisation in the field of manufacturing, conversion and testing of building and construction, including all aspects of their effects on man and his environment, relating to activities in the following fields; civil and construction, for example steel and concrete works, and the building industry, for example bricks, paving blocks, roof tiles, and cement concrete products. The primary activities carried out in this sector ensure that components and systems produced by the building and construction industry comply with the relevant standards. We also won the internationally advertised tender to perform third party quality and testing services on behalf of the Malawian government.

Strategic partnerships with the agencies of state have been established, including, but not limited to: • Council for the Built Environment (CBE); • Construction Industry Development Board (CIDB); • National Home Builders Registration Council (NHBRC); and • South African National Roads Agency Limited (SANRAL). Growing environmental awareness and the increasing awareness of quality implies the need for standardised requirements and testing methods. An important area where standardisation plays a big role is the SANS 10400 series of documents, which forms the “Deemed to Satisfy” requirements, as a minimum guide to compliance with the National Building Regulations.

Energy Efficiency in Buildings
Energy Efficiency in buildings is a www (win win win). The reduction of greenhouse gas (GHG) emissions is an urgent concern in SA, a country that is one of the largest CO2 emitters globally. Buildings are the largest end users of energy, and account for 40% of the world’s end use of energy. Most of this consumption is for heating, cooling, ventilation and hot water. Our existing buildings are not designed or constructed to maximise energy efficiency. The construction of energy efficient housing will significantly contribute to the reduction of GHG. It is important to note that feasible saving potentials for EE are very large, both in new and existing buildings.

How do consumers react when energy costs go up or when availability is limited? The consumers simply opt for generating energy from other sources such as solar, generators and others. Why not save instead of generating? Everyone has a right to live and work in a safe environment. The main drivers for energy use are comfort, safety and security. Comfort in buildings constitutes heating, cooling, ventilation, lighting and acoustics. The SABS recently published two ground-breaking standards to assist government, municipalities, builders, property owners and the
www.tobuild.co.za
6/25/12 8:55:21 AM
Corporate profile like to ensure better energy efficiency in buildings going forward.
SANS 10400-XA - The application of the National Building Regulations Part X: Environmental sustainability Part XA: Energy usage in buildings
SANS 204 - Energy efficiency in buildings The main objective of SANS 204 is the reduction of operational energy use, without reducing comfort. Compliance with SABS 204 will reduce the use of energy from electricity, gas, oil, or other fuels used in buildings. The standard further addresses energy use by the building’s services to operate it, but excludes energy used in manufacturing/construction or energy use by portable appliances. Drivers for energy use – comfort, safety and security – the right to live and work in safe environment SANS 204 requirements reduce the use of energy from electricity, gas, oil, or other fuels used in buildings for heating, cooling, ventilation, hot water (heating and sanitary), and other services. When the requirements of SANS 204 are properly applied, energy efficiency can be obtained in one of the following manners • Insulating or shading the building fabric • Controlling heat flow through the building envelope and glazing • Reducing air leakage through building fabric • Creating internal air movement for cooling • Improving efficiency of heating, cooling and hot water systems.
Much standardisation work has already been done around individual energy-saving devices such as energy-efficient light bulbs and solar water heaters. Instead of reinventing the wheel, SANS 10400 Part XA incorporates these existing standards into a holistic overview of the entire construction process, which then serves as a single reference to help architects, building construction companies and other stakeholders to ensure that their buildings comply with energy efficiency requirements as described in the standard. SANS 10400-XA is a single reference for stakeholders to ensure compliance with energy efficiency requirements as per the NBR, and gives further requirements for: • The orientation of the building, with well-used areas facing North to make best use of natural sunlight and warmth; • Suitable roof overhangs to keep out the high summer sun, but let the winter sun, when the sun is lower in the sky; • Sensible fenestration (windows) to let in light and sun, but not so much that natural warmth or coolness cannot be retained; • The use of appropriate heating, ventilation and air-conditioning installations where required; and • Solar water heaters become mandatory with new buildings being erected.
