The A. Proctor Group helps CREATIVE SPACES The beginnings of Creative Spaces go back to 2004. Tayside Construction Forum was born out of the success of “Building a Better Tayside”. That event comprised a series of presentations, lectures, seminars and workshops that were intended to reach out, not only to those currently involved in design and construction, but to a much wider audience including the general public and importantly children in secondary education and their teachers.

Creative Spaces intention was to arrange a design competition that would introduce and encourage S2 students from secondary schools in the local area, to participate in a day long contest with a direct interface between education, design and construction. The 2004 Creative Spaces event was such a success that it has been repeated every year.

The A. Proctor Group were delighted to contribute to the recent Creative Spaces Event 2012 by providing Styrofoam for local school children to build architectural models.

Styrofoam is an extruded polystyrene foam material developed by Dow and is more than an effective thermal insulant. It has a unique combination of physical and chemical characteristics that make it a key component within a wide variety of today’s high performance composite structures. Styrofoam is lightweight, yet exceptionally strong, safe in use and capable of being precision - engineered. www. proctorgroup.com Enquiry No 6

Nationwide Windows Shortlisted for Best Partnership Project for Recycling in National Recycling Awards 2012 Hot on the heels of its recent Silver in the Considerate Constructors Scheme National Site Awards, Nationwide Windows is delighted to be shortlisted for the Best Partnership Project for Recycling in the National Recycling Awards 2012.

Managing Director John Whalley comments: “independent third party recognition like this from the National Recycling Awards is a fantastic endorsement of the significant time and financial investment we make as a company when it comes to recycling and sustainability. Our entry focused on the results of our collaborative partnering with customer Nottingham City Homes and profile supplier Eurocell which has so far resulted in 14,572 end-of-life PVC-U frames being recycled from the NCH Secure Warm Modern programme. The total tonnage recycled to date is 2,499.139 tonnes and is running a rate for 2012 of 95.86%. As well as minimising landfill, reducing our carbon footprint and creating a sustainable blueprint for replacement of A rated windows, we calculate that the installation of A rated windows is also helping NCH save a potential 0.25 million tonnes of carbon emissions across the city each year. ” www.nationwidewindows.co.uk Enquiry No 10

Xtratherm's Technical Team First To Be Awarded Individual BBA Certification Each member of Xtratherm's in-house technical team has been awarded BBA competency certification for U-value and condensation risk calculations - a first for the insulation sector.

Xtratherm Technical Manager Danny Kearney comments: "Achieving BBA status for each individual in our technical team is a great achievement and reinforces our commitment to delivering the best technical advice to architects and specifiers. Everyone in the team who liaises directly with customers on technical matters is fully trained to deal with each enquiry and it puts us in a leading position.

"Usually it is just the Technical Manager or one individual that is BBA accredited," continues Danny, "but we wanted our customers to get the same high level of expertise from every member of our team. Accreditation for individual team members is based on our ability to work with a variety of software packages available in the construction sector and gaining a widespread understanding of each so we can meet the needs of all customers, including those with a preferred choice of software. Our advice and support is geared to the needs of specifiers, builders and contractors who look for accurate, expert help and advice and can rely on the advice and calculations they get. " Xtratherm, a leading manufacturer of high quality PiR and phenolic insulation, supplies a wide range of high performance, innovative insulation products. This is coupled with comprehensive training support through collaboration with construction colleges and training organisations such as the CIOB (Chartered Institute of Building) so installers acquire the training, skills and knowledge they need on site to meet today's higher insulation standards. Achieving BBA accreditation for each member of the technical team completes the loop. It means Xtratherm can provide architects, specifiers and contractors with the best insulation products, the most effective application and a high level of expertise. www.xtratherm.com Enquiry No 11

FRESCO HAILS “GOLD STANDARD” ON-LINE CERIFICATION CARD A revolutionary on-line certification card, which promotes best practice and health and safety at work, has been hailed as “gold standard”. The Fresco Group, the leading Leeds-based flooring company, has been using the Reset Certification Scheme (RCS) Card for the past six months.

Phil Russell, head of business development at Fresco, commented: “This is a tremendous scheme, which has major benefits for everyone involved. As RCS cardholders, it helps our staff and our business, keeping us safe at work and safe in profit, as well as giving us an extra edge over our competitors”.

The pioneering RCS card, which has transformed the way in which the skills and qualifications of contract workers are checked and verified on-line, has been developed by Sheffield-based Reset and has been adopted by leading Yorkshire organisations, including Leeds Teaching Hospitals NHS Trust, University of Bradford, and Leeds Bradford International Airport. RCS enables such organisations to maintain a safe environment for visitors and staff and to comply with health and safety legislation. Other organisations across both public and private sectors in the UK are currently in the process of teaming up with Reset. Fresco originally adopted the Reset card as the firm is one of the main contractors at The Leeds Teaching Hospitals NHS Trust.

Mr Russell said: “As Reset’s scheme spreads, membership will be seen as a gold standard and a brilliant example of best practice by NHS Trusts, universities and other major organisations where contractors and sub-contractors are constantly on site. I cannot recommend the scheme too highly. I believe we are now members of an elite and trusted network of contractors, who place a massive emphasis on health and safety at work, instead of paying lip service to it.

RCS ticks all the boxes for both the organisations such as the NHS Trusts, who adopt and require it and the contractors like us who carry the RCS card.” He added: “Like all the best ideas, it is brilliantly simple in theory and tremendously effective in practice”.

Gary Duce, the managing director of Reset, said: “Fresco’s ringing endorsement means a great deal to us. It is very important that both the card verifiers like the NHS Trusts, and the cardholders, such as Fresco, appreciate the benefits of the RCS card. The scheme is now gaining real momentum, with clients across the food, health, education and transport sectors in the UK. The qualifications of contract personnel of our clients are recorded and retained for seven years, providing unparalleled reassurances and peace of mind to all RCS users. RCS is both time-effective and cost-effective,” said Mr Duce. He added: “Companies can find out instantly whether their contractors, sub-contractors and other individuals have the skills and accreditations to competently and safely do their job”.

The chairman of Reset is Ian Townsend, the leading Yorkshire businessman, who was formerly chairman of Sheffieldbased The Medical House, which he sold in a multi-million pound deal. Gordon Black CBE, another successful Yorkshire businessman, has also invested in Reset. www.rcscard.co.uk Enquiry No 13

Cantifix uses Heat Mirror Film extensively on Bromley new-build Cantifix project Sylvan Glade, which was completed in 2011 and featured on Channel 4 show Grand Designs; was the first residential building in the UK to use Heat Mirror Film extensively.

The project is a new-build on the site of the clients old 1950’s home in Keston Park, Bromley - which was demolished to make way for this stunning, serene family villa. Inspired by the transcendental feeling created by the light and space of a woodland clearing, the fluid plan curves link open and cellular spaces, and the glazed facades emphasize the dynamic relationship with the landscape.

The clients took responsibility for the selection of all materials and suppliers, and were delighted to be the first to use innovative product, Heat Mirror Film within their glazing. This superb energyefficient technology allows homeowners to experience all the health and wellbeing benefits of natural light, whilst minimising heat loss through the glass. The transparent, weightless film is capable of achieving u-values as low as 0.3 W/m2/K - and also prevents the house from overheating in the summer months by reflecting heat back into the environment.

Sylvan Glade was built in conjunction with Spaced Out Architecture Studio and Modillion Homes.

Unusually for a new building that takes risks, throughout construction the whole project team worked harmoniously to allow the design to realise its full potential - and to deliver to the fixed budget without compromise on the specification of efficient technology. www.cantifix.co.uk Enquiry No 14

Wicona Glazing Systems Specified For New Polar Research Station In Antarctica

A new Indian research station in the Antarctic is to feature high performance aluminium glazing systems from Wicona, which will have to withstand some of the most extreme conditions on earth.

Designed by Hamburg-based architects, bof Architekten, the research station Bharati will be sited on the Antarctic coast, having been transported from Germany via South Africa by ship as a series of prefabricated modules.

The station’s aluminium façade will be subjected to the severe climatic conditions of the South Pole, which include abnormally

high thermal and mechanical loads caused by blizzards, huge quantities of snow, high wind speeds and temperatures of -40° and below.

A large proportion of the building’s façade will be glazed using Wicona’s specially adapted WICTEC 50 curtain walling system. This will feature triple glazing, highly insulated panels, an incline of up to 15° at the two narrow ends, and will achieve a U value of 0.8 W/m2K. The system also had to allow for the assembly and disassembly of the façade for testing purposes in Germany before the final installation in the Antarctic.

By incorporating a high level of glazing into the station’s design, the 25 staff working there will have a magnificent view of their polar location and it will counter their sense of confinement.

15 scientists and logistics staff will live and work in the station all year round.

Bharati is India’s third research base in Antarctica. It will be a two-storey structure, raised on stilts and is designed to have a life span of 25 years, as well as to minimise any impact on the environment. It will use combined heat and power from renewable sources for heating, low sulphur fossil fuel, efficient treatment of effluent, and

The research station will weigh around 1,000 tonnes and comprises 134 prefabricated modules which have now been transported by ship from Antwerp to Cape Town. In South Africa, a further 50 modules that make up the construction camp were taken on board for the 5,200km journey by sea to the site in the Larsemann Hills on the northern edge of the Antarctic. The scheme is scheduled for completion later this year.

Wicona offers a range of technically advanced glazing systems for complex and bespoke aluminium faรงades. Its products include unitised and stick curtain walling, structural and roof glazing, highly insulated window systems and heavy duty doors. www.wicona.co.uk Enquiry No 15

On-trend urban look with RAK’s new Earth Stone tile collection RAK Ceramics has introduced its new Earth Stone range of porcelain tiles. Featuring a stunning mottled matt surface, the tiles have a distinct concrete-look and are available in a range of formats and neutral tones. Earth Stone tiles are suitable for walls and floors, in both interior and exterior applications.

On-trend Earth Stone colour options include Talc Ivory, Charcoal Clay Grey, Monazite Brown and Charcoal Black.

All shades are available in 29.5cm x 59cm rectangular and 60cm x 60cm square formats, as well as 30cm x 30cm mosaic designs.

Earth Stone porcelain is almost impervious to liquid absorption to 0.05% and virtually stain/scratch proof. Risk of thermal shock is eliminated as this range is fired at 1200°c during manufacture, and the low absorption rate ensures that tiles will not crack during the winter freeze/ thaw cycle.

Other new tiles to join RAK’s range include classic white statuario marble-effect White Smoke in a 60x60mm design; the 10x30mm Classic Series which features both matt and gloss finishes in a broad spectrum of plain colours and new Lounge Listellos - a series of glass and porcelain decorative borders. www.rakceramics.co.uk Enquiry No 20

APD offers advice on flue access Leading online access panel company Access Panels Direct (APD) has launched a campaign to raise awareness of the importance of gas flue inspection hatches.

In order to comply with part J of the Building Regulations, it is vital that gas engineers have full visual access to gas flues through every room and void, in order to be able to carry out their inspections.

National Sales Manager Ian Shakespeare explains: “Everyone has until the end of December 2012 to ensure that there is full visual access along the length of their flue. In some cases, boiler flues are hidden behind walls or ceilings or are boxed in, which can mean that access is required in two or three rooms of a building. APD’s hatches offer you the easy solution – order online and it can be delivered to you the next working day.”

At accesspanelsdirect.net you can choose from a range of different sized access panels, with 300mm X 300mm being the most common size for providing flue access. They can be fire rated, if necessary, and are available with a metal or plasterboard door to match the surrounding wall.

Howe Green Access Covers On Board the Cutty Sark Project

Howe Green access panels have been installed in the newly re-opened Cutty Sark visitor attraction. The world’s last surviving tea clipper was officially re-opened by Her Majesty The Queen on 25th April at its home in the Maritime Greenwich World Heritage Site, having undergone extensive works that required almost every inch of the 143-year old vessel to be conserved.

Over fifty 7500 Series aluminium access covers with bespoke Z-section supports were made to order by Howe Green, the industry’s leading manufacturer of metal floor, ceiling and wall access covers. Ellmer Construction installed single and multipart units under a unique glass canopy designed to allow people to walk underneath Cutty Sark itself and view the elegant lines of her hull. The space and opportunity for the construction arose following an incredible feat of engineering, which saw Cutty Sark raised by 11 feet onto steel supports in order to relieve the keel of the weight of the ship and help preserve her unique shape.

Howe Green’s 7500 Series aluminium access panels were fitted into raised access flooring within the new museum facility in order to provide a route to essential ventilation ducting needed to keep air circulating in what is effectively a large void under the historic clipper.

Designed for use with all types of hard floors, Howe Green 7500 Series aluminium panels sit 100% flush so as not create a trip hazard and offer proven reliability to withstand high levels of foot traffic. They are double sealed to ensure no water ingress or dirt trapping and provide a reliable and maintenance-free solution to accessing essential building services - ideal for what looks set to become one of the Capital’s most popular tourist attractions.

Each access panel from Howe Green is manufactured to client’s exact specifications. Thanks to modern manufacturing techniques and the company’s innovative approach to product design, the bespoke nature of the panels does not come with a price associated with bespoke manufacturing. Instead Howe Green is able to offer competitively priced panels, designed for exact purposes. www.howegreen.com Enquiry No 23

Solving A Problem Of Student Concentration 50/50 COLLEGE Blinds have helped to improve student concentration at Ashville College, a leading independent school at Harrogate, North Yorkshire. The problem arose in south facing teaching rooms overlooking sports fields where activities tended to divert the attention of students. It would have been easy to install opaque blinds but this would have made the rooms claustrophobic and increased the demand on artificial lighting.

The solution from CURTAIN AND BLIND SPECIALISTS was to install 50/50 COLLEGE Blinds with an opaque fabric on the lower half joined to a more open screen fabric in the top section. The opaque fabric provides privacy, and stops students looking out, while the screen fabric allows good light transmittance to the interior so that the need for artificial lighting is greatly reduced. www.cbsblinds.co.uk Enquiry No 27

Energy Efficient LED Emergency Lighting Serves A Dual Purpose The carbon footprint for the NHS England now stands at a massive 21 million tonnes a year. To address this The Department of Health has set an ambitious target of a 10 per cent reduction by 2015 and an 80 per cent reduction by 2050.

Lighting accounts for anywhere between 10-20 per cent of a hospital’s total energy bill and when set against a backdrop of increasing fuel costs, reducing expenditure on this resource can appear to be an insurmountable task.

However, the introduction and innovative use of light emitting diode (LED) emergency lighting has already resulted in significant savings for some forward thinking health estate managers.

Correctly specified, installed and maintained emergency lighting plays a vital role in keeping the occupants of a building safe from the potentially deadly consequences of a failure in the general lighting. While a traditional system is often just left in ‘standby’ mode until it is needed, the flexibility of a modern LED based system means that it can also be used as a secondary source of lighting – one that is far more cost effective than using the mains equivalent.

LED luminaires produce less than five per cent of the carbon emissions of fluorescent lighting and this allows operating costs to be kept to a minimum without compromising efficiency. They also operate via functional extra low voltage (FELV) power, meaning that a mains electricity supply does not have to be run to every luminaire, which vastly reduces the amount of wiring associated with 230V cabling.

22

As well as energy efficiency, an LED emergency lighting system offers enhanced levels of control. At particular times of the day when certain areas may have a much lower footfall, it can be used to provide general lighting via one of seven different levels of illumination. As each luminaire can be controlled independently, areas of a building can be lit where and when necessary, for example, residents in a care home can have low-level lighting overnight in their rooms.

The use of low-level lighting can also enhance security, giving the impression that areas that are in fact closed are occupied. It is also possible to have a separate switch so that the emergency lighting system can be activated to provide light at a pre-determined level to assist manned security patrols.

While lighting can be controlled via timers and light levels configured to suit particular requirements, in the event of an alarm situation the system will resort back to its primary use and adjust the light levels accordingly.

Although reducing energy consumption is a formidable challenge, the savings possible by using LED based emergency lighting are significant and can go long way in helping healthcare estate managers achieve their carbon reduction targets. www.hochikieurope.com Enquiry No 31

Best Collection Of Custom Mosaics And Agglomerates Italian tile maker Trend has introduced a truly innovative series of decorative ‘designer’ finishes for indoor and outdoor environments, under the evocative title ‘Best Collection’.

Unique in its use of handcrafted glass mosaic and agglomerate materials for the coordinated covering of walls and floors, and exclusive in its selection of monochromatic patterns, Trend’s latest collection is the work of Italian artist and designer, Veronica Tommasin, who drew her inspiration from floral motifs and geometric forms. With a choice of dozens of different elegant patterns and formats, Best Collection offers the designer and consumer endless ways of expressing their style and creating decorative backdrops that merge different tones, textures, shapes and materials, with an unmistakable effect.

What distinguishes this decorative collection from any other on the market is the combination of authentic Italian glass mosaic tiles, many shaped by hand, and recycled glass agglomerate panels, waterjet-cut to produce exclusive composite patterns. Each material brings its distinctive finish and technical characteristics to the design palette, in dining and drawing rooms, bathrooms and wet areas, kitchen and utility rooms, reception areas, even outside patios and swimming pools. All the while, the varied yet harmonised patterns of the Best Collection hold the different design elements together.

Designer Veronica Tommasin was able to draw upon a vast range of mosaic tiles and agglomerate finishing and flooring formats from the master catalogue, while working to Trend’s brief of primarily neutral monochrome and tone-on-tone colourways that would deliver elegance without ostentation. Her inspirations come from her love of art, travel,

nature and diverse cultures, with her designs born from classic forms that have been reinterpreted from a modernistic viewpoint.

Best Collection artistic mosaics take three different floral forms – roses, elegant calla lilies and the aquatic water lily – and are executed in 1cm x 1cm micro mosaics, in various predefined modular sizes. Selected ‘artistic’ versions feature hand-cut tiles to create curves and uneven edges, adding an artisan dimension to the design. Colours are mostly black, grey, white and neutral tones of brown and sepia, selected by Veronica from Trend’s 1 x 1 Vitreo, Brillante, Shining and Feel ranges.

The same colours are adopted for the geometric mosaic modules, influenced by the straight, clean lines of geometry and the curved forms of musical instruments and notations. Here again, module sizes vary to give different interpretations of scale.

Trend employs modern waterjet-cutting techniques to apply much the same designs to 6.7mm thick agglomerate sheeting, bringing the decorative theme down onto floors, across to furniture and partition cladding, and an alternative texture and look to walls. Modular sheet sizes are mostly 120cm x 120cm or 60cm x 60cm, although there are also rectangular framing and edging pieces in geometric stripes and zig-zag patterns. www.trend-gb.com Enquiry No 32

Sika In Precast Role At Manchester Metropolitan University Sika concrete admixtures were incorporated in the concrete mix for the production of black precast concrete panels, produced by Thorp Precast for the new Business School and Student Hub building at Manchester Metropolitan University. The panels are a prominent aesthetic feature of the structure, with some surfaces being highly polished, so a good surface finish was essential. To achieve this, the concrete had to be produced to a high standard.

Incorporating the Sika admixtures in the mix helped reduce efflorescence and the number of blow holes within the finished panels, which greatly reduced wastage and the amount of finishing required. The concrete was also designed to self compact, which eliminated the need for noisy vibration of the panel moulds in order to mechanically compact. The building has been shortlisted for “Project of the Year’ in the 2012 Building awards. www.sikaconcreteadmixtures.co.uk Enquiry No 34

DRICON Treatment up to the challenge in the Highlands and Islands Lonza Wood Protection's DRICON fire retardant treatment is protecting the oak lining used in a beautiful award-winning home at Boreraig, on the Isle of Skye. The building, inspired by the blackhouse, a traditional style of Highland architecture, was designed by architect Neil Stephen of Dualchas Building Design to reflect the local landscape and heritage and to be a quiet and restful retreat for its Buddhist owner.

The house, facing a lochan and with views across the island, is lined throughout with oak-faced ply vacuum-impregnated with the DRICON fire retardant, creating a clean, minimal and attractive finish. The oak-finished panels spring open to reveal concealed shelves and storage areas to maintain the minimalist feel of the design. The wood was supplied by the timber contractors and shipped to Lonza Wood Protection for pressure-treating with the DRICON treatment before being returned to the site, ready for use.

KEMPER LAUNCHES TOTAL GREEN ROOF SOLUTION WITH ‘KEMPERGRO’ Liquid waterproofing specialist, Kemper System, has launched KEMPERGRO, the company’s first ever complete green roof system.

Suitable for use in both newbuild and refurbishment projects, KEMPERGRO has been designed to enable specifiers to source a complete green roof from a single supplier and builds on Kemper System’s existing track record in the green roof sector. Kemper System’s KEMPEROL wet-on-wet liquid waterproofing membranes, including the environmentallyfriendly solvent-free KEMPEROL 2K-PUR system, offer root resistance and a service life in excess of 25 years, making them an ideal base for green roofs and a common specification beneath externally sourced green roof systems.

KEMPERGRO is a three section green roof system comprising a reservoir attenuation composite, growing medium and vegetation. The reservoir attenuation layer includes an upper filter fleece, central reservoir core and lower protection fleece all of which are manufactured using over 90% recycled materials which helps to enhance the green roof’s environmental credentials. All three components are factory bonded to maximise performance and simplify installation, preventing sagging under the weight of the growing medium to maintain reservoir capacity and prevent blockages.

The growing medium is 100% composed of recycled brick, tiles and green compost and is processed and graded to support an extensive range of

30

sedum, meadow and lawn roof media, all of which are grown and sourced in the UK. Whether the requirements are for sedum matting, plug plants or seeds, Kemper System can provide a solution to meet local climatic conditions, aspect, biodiversity and specifier preference and the company can advise on the most appropriate growing medium to match the specific needs of individual projects.

In addition to providing a natural, living roof environment created using recycled materials, the KEMPERGRO system also helps to enhance the environmental profile of refurbishment projects by enabling installation on top of the existing substrate. This ensures that strip out and removal of existing roof materials to landfill can be avoided. For refurbishment installations, Kemper System’s hard top insulation board can often be bonded directly to the existing substrate, using the existing waterproofing as the vapour control layer. This is followed by KEMPEROL waterproofing, the attenuation layer, the growing medium and finally the sedum or vegetation.

Harry Cowell, managing director of Kemper System comments: “Green roofs are amongst the most popular ‘eco’ features in contemporary building projects but ensuring that this type of living roof thrives, enhances the building and has no detrimental effects on structural integrity is a complex undertaking.

Kemper System’s track record in sustainable and environmentally-friendly products, along with our roofing expertise and substrate conservation means that specifiers can be completely confident of a high quality end result with KEMPERGRO while rationalising their supply chain.” www.kemper-system.co.uk Enquiry No 45

measurements and note the various surfaces before discussing the acoustic requirements of the hall, and any considerations that would need to be given in terms of aesthetics and practicality. The room in question was a large, open sports hall, used by the children for their Games lessons as well as practicing and training for the schools various sports teams. The hall had a lot of hard, acoustically reflective surfaces on the walls, floors and ceilings and as soon as any number of children entered the space, the noise echoed and reverberated around the hall making for a very unpleasant environment.

The data taken from the site visit is inputted into SRS’s reverberation modelling software, and by adjusting the level of absorption within the equation, SRS can specify, to the exact panel, the area of absorption that is required to achieve the desired result. A report, quote and layout suggestion is then emailed to the school for their consideration. Building Bulleting 93 (BB93), the document that specifies acoustic conditions within schools, recommends that the reverberation time for a newly built multi-purpose school hall should be <1.5s – and the proposed treatment was sufficient to meet this standard.

To treat the sports hall at Charlton School, SRS proposed the use of 126m2 Sonata, their high performance acoustic absorber range. Sonata Vario panels were suspended across the ceiling and also fixed at high level on the walls to ensure good, even absorption across all frequencies. From the many different colours available, the school chose ‘Smoke’ which they thought would look the best in the hall. www.soundreduction.co.uk Enquiry No 54

As consumers become increasingly aware of the environmental and economic benefits of water conservation, the BMA has introduced a labelling scheme that follows the same principle as the EU Energy Label and rates products by its water efficiency from A to G. Altecnic’s patented Calflow Plus, which is also WRAs approved and carries the Waterwise marquee, regulates water flow to approximately six litres per minute and incorporates a filtration mesh that helps prevent debris entering and damaging valves. Over three years it is estimated that by installing Calflow Plus, an average household can reduce utility bills by as much as £300* and by installing the device on all outlets could save approximately 9,125 litres of water per person, per annum. Calflow Plus is quick and easy to install and has been developed and manufactured to the highest quality Italian standards. As well as flow regulation, it also aids even distribution in a multi-outlet new build and is capable of regulating water flow between 2 – 18 litres a minute, operating up to an intlet pressure of 16 bar. *OFWAT gives the cost of supply and sewage at £0.002 per litre.

Trend Controls claims developers are failing to make buildings fit for purpose Despite the on-going drive towards greater energy efficiency within buildings,Trend Controls believes that some property developers are failing to recognise the long-term value of installing a fully featured building energy management system (BEMS) at the initial construction stage. The company argues that this lack of foresight is leading to a situation where a significant number of new builds are simply not fit for purpose.

Implementing a BEMS means that energy savings of 10-20 per cent can be achieved when compared to controlling each aspect of a building’s infrastructure separately and a fully integrated solution can manage up to 84 per cent of its energy consuming devices such as heating, ventilation, air conditioning (HVAC) and lighting.

So why isn’t the design and installation of a BEMS happening as a matter of course? The answer is a combination of cost and lack of foresight, according to Trend Controls’ strategic marketing manager, Chris Monson, who commented, ‘As there are no regulations stating that a BEMS must be installed, there’s a strong possibility that it won’t be. However, this lack of forward thinking leads to future occupants having to cope with higher overheads and a larger carbon footprint.’

Despite the growing uncertainty surrounding the Carbon Reduction Commitment (CRC) Energy Efficiency Scheme, even if this particular initiative is abolished it will probably be replaced by a similar scheme, such as a carbon tax, which could affect businesses of all sizes.

For the time being at least the CRC is part of the carbon reduction agenda but it isn’t the only driver for energy reduction – the Climate Change Levy (CCL), Air Conditioning Assessments, Display Energy Certificates (DECs) and Energy Performance Certificates (EPCs) all impact upon businesses.

‘There are those who feel that regulation is the only way to make sure that BEMS are installed at the point of initial construction, although others are reluctant to see the introduction of more onerous restrictions on an already pressured construction sector,’ concluded Monson. ‘The point is that regulation shouldn’t be necessary if a long-term approach to energy efficiency is factored in and the benefits of a BEMS in being able to achieve savings are considered.’

Sudscape Hits The Heights For Trowbridge Town Council The re-development of the Civic Hall (*) in Trowbridge Park for Trowbridge Town Council by Beard Construction has involved the installation of an innovative hard landscaping system that offers unique eco-friendly qualities.

Sudscape is a SUDS compliant porous paving system which has been used to surface the first-floor balcony of the new building from where the Lord Mayor can address the public. Sudscape is largely comprised of recycled car tyres which form a sub layer, coupled with a top layer of resin bound aggregate.

It was considered ideal for use on the balcony by the specifier, Construction Services Group Hydrock, because it is light weight, does not require special machinery or heavy plant for the installation process, and boasts excellent drainage properties, with the rubber sub base holding rainwater from where it can naturally and effectively drain into the rainwater sewers.

The fact that Sudscape is available in a range of colour finishes means that it complements the interior scheme of the new building, effectively harmonising the exterior with the interior. In addition Sudscape requires very little ongoing maintenance, with no need for pressure washing or any specific cleaning regime.

Mark Buckley of Beard Construction comments: “With environmental considerations now a key part of building criteria we were very keen to use a product which has substantial eco credentials. The fact that the Sudscape product boasts a range of other benefits, including easy maintenance making it ideal for installation on a balcony made it the natural choice.” www.sudscape.co.uk Enquiry No 63

OPINION|GLAZING Heat Mirror Film vs Triple Glazing – Our Verdict

With energy prices rising, carbon legislation changing, and homeowners becoming more environment-savvy; the pressure is on to find ways of minimising the heat lost through glass.

Triple glazing is currently being heavily promoted and heralded as the future by various glass manufacturers; whilst lightweight alternative Heat Mirror Film has still to make a big impact in the UK market.

Cantifix installs both products – but here’s our take on why we are backing Heat Mirror Film as the ideal solution to heat loss through glass…

What Is Heat Mirror Film?

Heat Mirror Film was developed by the MIT (Massachusetts Institute of Technology) in 1979, as the result of a USA government funded research programme; and released commercially

by Southwall Technologies in 1980. It is a polyester film with a transparent, multi-layer metallic coating that transmits light, but reflects long-wave infrared energy. This coating is applied by the electrical process ‘magnetron sputtering’.

Although there are a subset of films suitable for different aspects and climates, the overall

38

principle is very simple - the tiny particles of metal within the film reflect any radiation (heat) back to where it came from - so in the winter it reflects heat back into the home, keeping it warm and minimising heating bills. In the summer it reflects heat back into the environment - stopping it from overheating inside.

What About The Figures?

A standard double-glazed unit (using low-e glass and an argon filled cavity) with a single sheet of Heat Mirror Film suspended in the cavity will achieve average u-values of 0.6 w/m2/k, whilst the same composition with two sheets of Heat Mirror Film will achieve an average u-value of 0.3 w/m2/k.

This is well below the PassivHaus requirement of 0.8 w/m2/k - and easily equivalent to what is achievable with triple glazing. As well as blocking heat, the film also blocks more than 99.5% of damaging UV rays – protecting furnishings from fading and degradation caused by the sun; and reduces sound transfer by 2-3 dB (compared to a standard unit) - creating a quieter internal environment. The benefits delivered by Heat Mirror Film are exactly the same whether it

is installed vertically or horizontally, and the product can be combined with any gas infill or coated glass.

How Does It Compare To Triple Glazing?

Whilst triple glazing might boast similar u-values to those achievable with Heat Mirror Film, these come at a very heavy price – around 10kg per square metre of glazing. In the case of structural glazing this means that a costly crane would be required far more frequently, and the logistics of installation could become difficult.

Even for simple windows and doors, the extra weight of each glazed unit would make installation trickier, and potentially compromise the ease of operation - as well as the service life of hinges and fittings. In products such as folding or sliding doors, this issue can be solved by using a larger number of smaller panels – but most homeowners are keen to minimise framing, not increase it.

In terms of financial cost; both triple glazing and Heat Mirror Film offer substantial savings in energy bills, however triple glazing is far more expensive - both in terms of procurement and

OPINION

installation. Homeowners can expect to pay around £150 extra per square metre for Heat Mirror Film.

But Is It Reliable?

There are diverse opinions within the industry about the reliability and longevity of Heat Mirror Film. The product has been around for over 30 years, and was recognized as one of the Top 100 Inventions of the Millennium by Popular Science magazine in 2000.

Over 3 million square metres of Heat Mirror Film have already been installed, and there are many long-standing examples of its durability – including Werner Sobek’s ‘Low Energy House’ which was completed 12 years ago, and uses the film in each of its 4 glass walls.

If any further reassurance were required that Heat Mirror Film is the ideal energy-efficient glazing product, the retrofit recently completed on the Empire State Building is a great example. Every single one of the 6500 windows in the building was retrofitted with Heat Mirror Film, as part of a program designed to reduce the building’s energy usage by 38% per year.

The updated windows are expected to save a massive $400,000 in energy bills per year. Heat Mirror Film is durable, scalable, proven, and provides unmatched insulating performance, and its use in the Empire State Building project is perfect validation of this.

Cantifix Director Charlie Sharman concludes with his thoughts on the comparison; “We are all aware that there is an ecological price to pay for our high level of energy use in our living and working environments. When you combine this with the human need for daylight it was obvious to Cantifix that a solution had to be found to reduce energy consumption without compromising light transmittance. The cost and weight of a double glazed panel incorporating Heat Mirror Film, compared to a triple glazed unit, makes the decision an easy one to make. I will not be surprised if Heat Mirror Film becomes the standard specification for all glazing projects within the next 5 years.”

Please note: Cantifix will happily supply and install triple glazing if this is the preference of the customer. www.cantifix.co.uk

OPINION|kitchen ventilation A GUIDE TO COMMERCIAL KITCHEN VENTILATION SYSTEMS Steve Leonard is Managing Director of Ledaire Fabrications

The health and safety of kitchen staff and customers in cafes and restaurants is an important consideration for operators. Steve Leonard is Managing Director of Ledaire Fabrications, a specialist producer of tailor-made stainless steel cooker hoods for commercial kitchens. In this article he answers questions on standards and product selection.

What are the main risks that staff face in a busy kitchen?

There are three types of risk - to personal health, to food hygiene and to third parties. In all cases efficient ventilation is needed, expelling fumes while bringing in fresh, clean air for comfortable, safe working.

Carbon monoxide poisoning from incomplete combustion is a well-known risk. While less well known and not lethal, a carbon dioxide build-up above 1000ppm, from incomplete combustion of gas, can cause headaches, drowsiness and loss of concentration, with consequent dangers.

How do we overcome these problems?

There are two valuable publications: HVCA Kitchen Ventilation Systems Standard DW172 and the Health and Safety Executive Catering 40

Sheet No. 10 â&#x20AC;&#x153;Ventilation of kitchens in Catering Establishments.â&#x20AC;?

Systems must comply with British Standard BS6173:2009, which requires interlocking of mechanical ventilation systems and gas supplies for all types of commercial kitchen appliance, preventing a gas appliance from being switched on before the ventilation system is operating.

Grease and dust can accumulate in hoods and canopies. Is this dangerous and a health hazard?

Besides evacuating fumes, systems need to avoid a build-up of grease in ducting and prevent insect pests being drawn in with replacement air. Most cooking oils flash off inflammable vapours above 200oC and this flashpoint reduces with oxidation from repeated use.

Prevention of grease accumulation is very important. If not addressed, it provides a feeding ground for bacteria and insects and also accelerates fires.

Many grease filtration options are available and both filter replacement and easy cleaning are key considerations. Fire suppression systems can be

built into hoods. Filtration, however, is only fully effective in conjunction with regular maintenance and performance can be enhanced with choice of hoods.

How do I know if my ventilation system is right for the size of kitchen?

HSE recommends a kitchen ventilation rate of at least 17.5 litres/m2 of floor area, or 30 air changes per hour. This is fine in summer, but not in winter when more controllable ventilation may be desired.

A basic hood will extract a given volume of fumeladen air, together with its heat, but induction hoods partly separate fume extraction from ventilation. They draw in fresh air for highvelocity discharge into the hood, which creates a low-pressure zone over the work area and helps to extract fumes via the hood and filters. www.ledaire.com

OPINION|CO Alarms CO Isn’t Exclusive To Boilers Michael Wright, Product Manager, Aico Ltd

When it comes to the dangers of Carbon Monoxide (CO) poisoning in the home, many homeowners that have their boilers serviced annually could be unaware of the potential risk of CO poisoning. They think that once their boiler has been checked and certified they are completely safe from any threat of CO poisoning for the entire 12 months that follows. Of course, that’s not entirely true – and it’s a dangerous assumption.

Firstly, boilers can and do go wrong in between annual inspections, despite the thoroughness and quality of the last service or inspection.

Secondly, the focus on boiler safety in recent years, whilst valuable, has had the unintended consequence of reinforcing the idea that boilers are the only possible source of CO emissions in the home. Nothing could be further from the truth. Last year a lady in Cornwall was poisoned and permanently disabled from a CO leak from her cooker. She had been having her gas boiler serviced annually but was unaware that any fossil fuel burning appliance has the potential to emit CO gas.

Thirdly, it’s not just the resident’s home that could be the source of CO. There are proven cases where people have been poisoned by faulty appliances from an adjoining property.

What can be done?

It’s impractical to start asking householders to have multiple inspections on all their appliances throughout the year, plus their neighbours’ appliances. Practically there is only one realistic course of action and that is to install CO alarms.

Anyone working in this sphere, from heating and ventilation engineers and electrical contractors through to architects, have a pivotal role to play here as they need to explain the issues to their customers in a clear way without scaring them. The next step is to stress the importance of installing CO alarms. Almost everyone now understands the necessity of installing smoke alarms, and a direct comparison can be drawn. It can be explained to the householder that, since CO emissions can’t be detected by any of the human senses, a CO alarm is the only way to know that they are safe.

In an ideal world, householders would fit a CO alarm in every room where there is a fuel burning appliance, as well as perhaps in the master bedroom for added safety. As this is not always affordable, the next best option is to fit a CO alarm in close proximity to the appliance most likely to produce CO fumes, which is often a flue-less or open-flued appliance in the kitchen or living room. If there is a CO incident during

the night when occupants are asleep away from the CO alarm, they may not hear the warning, so interconnecting it with the home’s smoke alarm system is an economic way of solving the problem of audibility.

There are a number of systems that now allow for this to be achieved wirelessly, such as Aico’s RadioLINK system. The alarms do not require hard wiring to each other, which is time consuming and disruptive to retro fit, but instead communicate by Radio Frequency signals.

When one alarm sounds, they all sound providing audible warning throughout the property.

Since it is important to differentiate between fire and CO once the alarm has been raised, a wall-mounted Alarm Controller should be used.

Using the controller residents can quickly locate the exact alarm which has registered the fire or CO and take appropriate action.

The danger of CO in the home is now finally hitting the headlines and awareness is spreading.

But the full extent of sources of CO in the home remains relatively unknown, even amongst professionals. It’s up to all of us to not only explain this, but also provide easy to understand and implementable solutions. www.aico.co.uk

Wood Awards Gold Award Winner 2011 Rothschild Foundation, Buckinghamshire by Stephen Marshall Architects using European oak

OPINION

The new complex of buildings by Stephen Marshall Architects for the Rothschild Foundation and Archive includes office space for the charity investment organisation, a library reading room, offices for archive staff and the archive stores.

two storey building across the courtyard used as the charity investment offices. Between the office building and the archive group is a formally landscaped garden that serves as the arrival courtyard to the whole project.

Cullinan’s design uses oak its strength and flexibility and home-grown western red cedar for cladding. All the timbers were chosen for the local availability, suitability and low environmental impact.

The main space is the archive reading room, which was designed as a modern reinterpretation of a barn structure. The structural frame is a timber diagrid formed from European oak glulam beams veneered in European prime grade oak. Over the beams is a stressed skin ply roof again with an oak veneer finish.

The judges said, “The Rothschild Foundation is a wonderful piece of modernism married to a Victorian farm in the depths of the English countryside. The minimalist open-folded plate roof carried on pencil-thin columns is crafted like a piece of furniture.”

The judges said, “I could have stood there all day just looking at it.” They praised the skill for execution of the election process and said the structure was an amazing feat of wood engineering.

On the north side the building is carried to ground with solid oak V columns next to full height glazing. On the south side the roof is supported from steel posts hidden within 4.5m-high oak pivot doors. The reading room structure is complemented by oak flooring, oak bookcases and bespoke reading tables.

The cladding of the archive barns adjacent to the reading room is formed in European oak vertical boarding with oak ledged-and-braced doors and shutters. A similar treatment is used on the

American softwoods species - Southern Yellow Pine Southern Yellow Pine lumber (also known as Southern Pine) has long been popular in the US for a wide variety of applications. Favourable growing conditions, longterm careful forest management, and efficient manufacturing ensure a continuous supply of high-quality Southern Yellow Pine products for future generations.

UK building regulations require construction materials to maintain adequate mechanical stability and strength throughout their design life. For treated wood, the characteristics of the species are an important aspect of meeting these requirements. Some species are classed as ‘resistant to treatment’, while others are classed as ‘easily treated’, allowing the preservative to penetrate deep into the timber. Because of its unique cell structure, Southern Yellow Pine can achieve exceptional depth and uniformity of treatment penetration, making it the preferred species in the US for preservative impregnation where it accounts for over 85% of all treated wood purchases. Pressure-treated under a national quality assurance scheme, and the pre-eminent choice of the construction industry in North America, Southern Yellow Pine is widely available in the UK. Southern Yellow Pine is not a single tree species, but a collective term used to describe a range of species that, once felled, are virtually indistinguishable from each other. The four principal species which make up the Southern Yellow Pine family are loblolly, longleaf, shortleaf and slash pine. All are native to the US and grow mainly in a broad geographic region from eastern Texas to Virginia. Even though 97% of American homes are of timber frame construction and more wood is consumed per head of population in the US than anywhere else in the world, the forests of North America cover the same land area as they did 100 years ago. Because more trees are planted every year than are harvested, these forests continue to grow in size.

Appearance Southern Yellow Pine has a distinctive and attractive appearance, with a straight but uneven grain pattern and few knots. The sapwood has a yellowish-white hue and the heartwood is red-brown or orange. Growth rings display a distinct difference in colour between early and late growth each year, which makes Southern Yellow Pine sought after for decorative applications.

Although Southern Yellow Pine contains resin, it is moderately easy to work with machine or hand tools and takes paints or stains readily. A sealer is recommended to prevent any potential resin bleed. It glues well, and, because of its density, has excellent nail and screw-holding properties.

Applications Southern Yellow Pine can be used for a wide range of applications, including decks and boardwalks, interior and exterior cladding, flooring and bridges. Because of its inherent strength, treatability and beauty, pressure-treated Southern Pine has become the principal species in North America for construction and engineering applications. The landscaping applications for pressure-treated Southern Yellow Pine are numerous, including pergolas, arbours, gazebos, screening, fencing, outdoor furniture, path and border edges and earth retaining walls. www.americansoftwood.com Enquiry No 68

The carbon sequestration during each tree’s growth more than offsets the total combined emissions from harvesting, processing and even transport of the timber to the EU from the US. American softwoods also offer a sustainable, fast growing and, when pressure treated, durable alternative to much more expensive tropical hardwoods, which can take three times as long to mature.

Norbord Cabershield: A new generation of weatherproof flooring Norbord has extended its range of particleboard flooring products with the launch of Cabershield, a moisture-resistant P5 tongue-and-groove board with a permanent protective non-slip coating.

Complementing Norbord’s Caberdek – the UK’s leading peel-clean board - Cabershield is made from the same 22mm P5 board but with a tough polyurethane coating permanently bonded to the top surface. As well as making the floor safe and waterproof, the PU coating on Cabershield is really tough. Like Caberdek, a newly-laid Cabershield floor can be left exposed to the elements for up to 42 days without risk of deterioration.

Cabershield is fully BBA-certificated and independent tests have shown that its protective coating is three times more durable than the nearest competing product. The new board has just completed a year of pre-launch pilot projects with Norbord customers who have reported excellent results, says Bill Miller. Cabershield is very quick to install using Norbord’s Caberfix’s new Joint & Joist adhesive. This adhesive is 100% waterproof which means that, when used with Cabershield boards, there is no need to tape the joints after installation. www.norbord.com Enquiry No 70

House Of SmartPly O2i design consultants were asked by their client, an international artist, to make almost every visible interior surface of their two barn conversions in Somerset, exposed OSB. The project was recently completed, and 15mm tongue & groove SmartPly OSB is without question the material of choice.

After discussions with the architect, contractor Cann Building Services Ltd and the local building control department, SmartPly OSB was specified because of its zero added formaldehyde and environmental credentials, as well as its local availability. Samples were supplied and tested for suitability of use and acceptability by the Building Control Department who, with requirements for an appropriate intumescent fire retardant, agreed and was satisfied.

The project involved the conversion of two Somerset barns into an open plan workshop and living space and now virtually the entire interior is dedicated to SmartPly OSB. The timber panel sits comfortably with the existing timber roof structure, and now forms the walls, ceilings, sub-floors, reveals for windows and roof lights, frames and doors for the kitchen units and bench seating, doors, door linings and stops, sliding wardrobe doors, balustrade panels, shelving, TV cabinet, and boxing and battens. Even the stair treads are three layers of SmartPly bonded together. Underneath the OSB wall surfaces the contractor developed his own OSB ‘eco-batten’ to replace solid timber, comprising 50x15mm and 50x30mm bonded OSB. The client wanted to retain the unique pattern of the OSB so the panels have been stained and varnished and finished with a clear, water-based fire retardant. Andrea Pyle of O2i Design said, “The client was keen that the finish should not alter the OSB’s appearance.

The smooth finish and high grade enabled the building contractor to scribe the sheets of SmartPly around existing beams and structures without too much difficulty.” The 15mm tongue and groove panels also matched up neatly without leaving unsightly gaps. “The OSB finish has

48

given the space a warm, natural and serene feel, very much in keeping with the beautiful rural surroundings,” added Pyle, who said that she would consider using it in a similar context in future projects. “OSB is a flexible, warm, natural and sustainable product. The possibilities are endless.” The building has high levels of thermal performance through insulation and glazing and airtightness, as well as incorporating energy-efficient fittings and appliances.

High levels of insulation, including sheep’s wool were used in the roof and the large areas of south facing glazing of 1.1W/m2K U-value allow some solar gain. The front of the building is fitted with sliding oak shutters, which control solar gain by shading the space.

SmartPly OSB 3 the only commercially available OSB manufactured using zero added formaldehyde in the UK and Ireland. Being owned

by Coillte, the Irish forestry and forest products company, SmartPly is able to use Coilte’s FSC certified forest resources to make their products with security of supply. The unique properties of SmartPly OSB have led to it being been approved in the general construction sector as a sustainable alternative to plywood. www.smartply.com Enquiry No 73

TIMOLEON LOWBOARD UNDERFLOOR HEATING SYSTEM INSTALLED IN HISTORIC LODGE Holwood House, one of the grand mansions in the Bromley area, was built in 1825 to a design by Decimus Burton on the site of a previous house owned by William Pitt the Younger, Britain’s youngest Prime Minister elected in 1783. The most southerly of the three lodges to Holwood, built at the same time as the House is only a short stroll from the Wilberforce Oak under which William Wilberforce told Pitt of his intention to introduce a bill in the House to abolish slavery. The present owner after discovering crumbling plaster in several rooms on the ground floor (especially in the awkward areas behind the radiators) has taken the opportunity to bring their central heating up to date by replacing the radiators with an underfloor heating (UFH) system.

Timoleon’s LowBoard system which is one of the slimmest water based underfloor heating systems on the market, is specifically designed to be laid directly on an existing surface and with a total height of only 13mm, proved ideal for this refurbishment project.

The Timoleon design team prepared detailed drawings for three circuits of 12mm polybutylene piping in a conformation that would grant maximum spread of heat. These were to be connected to a single manifold with water mixing valve and temperature control which was connected to the existing 22mm boiler primary pipework. Room temperature control was achieved via a wireless thermostat with a wiring centre at the manifold location. The Timoleon LowBoard panels were then laid on top of the existing floorboards and secured in place.

The panels are made from high density plywood with an aluminium layer on the underside that helps to spread the heat upwards into the room and are straightforward to lay on any reasonably flat surface. LowBoard panels are prerouted enabling the installers to gently tread the 12mm flexible pipe swiftly and with little effort. The flow and return pipes were then connected to the manifold and the system was pressure tested. To complete the refurbishment the owner laid 5mm thick underlay sheets over the LowBoard panels followed by laminate flooring and then re-plastered the walls where the radiators had been.

The UFH was installed rapidly and the owner was told valuable information on how the system works, including how to operate and adjust the Axios manifold during the commissioning session. The Timoleon system has proved extremely effective in providing a very comfortable room temperature with the floor surface temperature a toe-warming 25-27ºC even on the coldest of days. The water used in the LowBoard UFH system is at a much lower temperature (50ºC) in comparison to radiators.The previous radiator system needed a temperature of 78º in order to heat the same space. www.timoleon.co.uk Enquiry No 74

DuPont, SNCF and RFF present a durable, reliable and environmentally-friendly solution for stability and preventing weed growth Geotextile and landscaping membranes from DuPont have long been valued for the stability and sustainability they offer to the external built environment and now these properties are increasingly being optimised in railtrack engineering. In a pioneering renovation programme for a section of track in France, an innovative solution to both safety and environmental concerns has been applied, thanks to a forward-thinking collaboration between DuPont, rail network owner Réseau Ferré de France (RFF) and the French national railway, SNCF.

The northern stretch of the line between Moret/ Veneux-les-Sablons and Lyon was laid originally in 1860 and a replacement of ballast and track last took place in 1975. However, standard maintenance methods were no longer sufficient in this case, for vital reasons of safety and sustainability.

The ballast had become seriously degraded and contaminated by soil particles requiring radical renovation.Track stability was not the only issue affecting the replacement programme, however, due to ecological sensitivities where the line crosses a protected water catchment where use of herbicides will soon be prohibited. These restrictions called for another answer to the problem of weed invasion - one that would also ensure the long-term integrity and performance of the infrastructure.

The search for alternative solutions to weed control resulted in a new partnership between RFF, SNCF-IG and DuPont to develop and test the

50

company’s non-woven fabric applications in the first large-scale installation and long-term performance trial of its kind in France.

During night time operations, an advanced multi-function track-replacement machine lifted the superstructure (tracks and sleepers, all in one go), removed the contaminated ballast and then laid down DuPont™ Typar® SF geotextile, chosen for its proven high mechanical resistance and excellent filtration and hydraulic performance. The new ballast was then packed before the sleepers and rails were replaced.

A different product, DuPont™ Plantex® Gold, was chosen for the bordering pathways near a crucial crossing point, where weed control is even more critical. These areas tend to suffer from rapid colonisation by unwanted vegetation and must be kept clear for safety…a challenging task for which neither trimming nor herbicide treatment offers a lasting solution. Thus DuPont™ Plantex® Gold was installed directly on the subsoil and covered with 2 to 3 cm of sand.

DuPont™ Plantex® Gold offers a unique nonwoven structure of thermally bonded polypropylene filaments, which form a barrier to vegetation while allowing water to pass through. It has been successfully tested in application for more than 25 years, and its superior performance dispenses with the need for herbicides, meaning that in this environmentally sensitive area, both the quality of the catchment water and the safety of railway users and the local population will be enhanced and preserved.

Shared Ownership Apartments Go Green With NIBE Energy Systems Shared ownership apartments in the North West are leading the way with energy saving technologies thanks to NIBE Energy Systems. Liberty Place - a modern, purpose-built block of one and two-bedroomed apartments in St Helens, Merseyside â&#x20AC;&#x201C; has become one of the latest schemes to introduce NIBE Energy Systems eco-friendly technologies and provide residents with heat and cost effective energy solutions.

Commissioned by Helena Living, part of Merseyside-based social landlord Helena Partnerships and built by Cruden Construction, the scheme boasts exhaust air heat pumps which work by harvesting the heat energy created from human habitation and passing it through a new generation NIBE unit, where an ultra-efficient heat exchanger increases its temperature before recycling it back into the heating and hot water system.

The exhaust air is eventually expelled into the outside atmosphere during natural ventilation at a temperature close to zero, reducing carbon emissions as well as creating substantial energy savings. Early impressions from residents at Liberty Place reveal that NIBE units, which fulfill all the central heating and hot water requirements for each of their homes, are just as heat effective as they are cost effective. The NIBE unit incorporates a super insulated stainless steel hot water cylinder and circulation pumps in one sleek and compact unit, making it easy to fit into a cupboard.

Although comparatively new in the UK, exhaust air recovery has been popular in Sweden - where NIBE exhaust air heat pumps are designed and made - proving the systemâ&#x20AC;&#x2122;s capabilities and efficiencies in colder temperatures. www.nibe.co.uk Enquiry No 76

Refurbishing With Daylight One of the most dramatic Kalwall projects in Europe is part of the conversion of old railway maintenance buildings in Antwerp. The brief for architects Verdickt &Verdickt was to use as much as possible of the original to create a major leisure complex. This was to include a large new sports hall within the existing footprint, formed by retaining the gable walls and with a totally new structure behind connected to the main complex.

Maximum natural daylighting with minimum energy loss has been achieved by cloaking the envelope entirely with translucent Kalwall. This highly insulating system comprises a very large pitched roof, supported by laminated timber trusses, together with vertical clerestories at each end and along the long side elevation. Internally, the other long side forms an upper level viewing gallery. When lit up at night, the building exudes an ethereal glow.

Kalwall is the most highly insulating diffuse light transmitting cladding and sky lighting system available. It is designed to transmit "museum-quality" light, flooding an interior with natural diffused daylight without glare or the harsh contrasts of light and shade. Running costs are reduced because of the superior insulation which reduces a building energy running costs including less reliance on artificial lighting.

Potatoes Stay Cool With Kingspan Powerpanel The owners of Lavenham Fen Farm in Cambridgeshire have installed the Kingspan’s Roof PowerPanel Modules to slash bills from the farm’s two potato storage buildings. The buildings, separately housing standard and organic potatoes, require large amounts of energy to power internal cooling systems, keeping harvested potatoes at a constant low temperature. With electricity usage metered at half-hourly rates, this previously resulted in massive energy bills for the farm owners. To tackle these costs, the farm owners used investment from Regenerco to help fund the purchase and installation of Kingspan’s PowerPanel and Safetraxx systems.

The PowerPanel array, installed on the roofs of the storage buildings, comprises one thousand, five hundred and one, 235Wp Yingli crystalline PV modules and can produce an overall output of 352.7kWp. Kingspan Roof PowerPanel Modules are capable of producing electricity even in low light or overcast conditions and can enhance the asset value and rental potential of properties. The PowerPanel system at Lavenham Fen Farm has been registered and accredited under the FiT scheme. www.kingspanpowerpanel.com Enquiry No 78

90 METRE DEEP WELLS ON SITE? IDEAL FOR NIBE GROUND SOURCED HEATING! It takes real vision even to consider turning a large derelict, not over attractive, single story building into a family mansion with the very greenest of credentials, but that is exactly what has been achieved at Nutbourne Pumping Station.

Way back in 1893 one in ten of the population of Worthing were affected by Typhoid, 200 died all from polluted drinking water and by the 1920s similar fears were affecting Nutbourne, so it was decided to build a pumping station when clean water was found on Nutbourne common and in 1930 work began on constructing the Pump House using two 90 metre deep bore holes to extract water, which was then pumped up to the surface and stored and filtered for use.

The Pump House was officially opened in 1932 by the Lord Lieutenant of the County. The Pump House operated continuously until the 1970’s when it became obsolete. When the Pump House came onto the market for £269,000 with full planning permission and several thousand square feet of floor space in an attractive part of Sussex, Nick Sweet, an Architect and his wife Bridget decided immediately to purchase it with plans to go for a “no bills” residence by installing phoyo-voltaic panels on the roof and tapping underground heat from the old boreholes.

Now the Pump House has been transformed from a damp echoing shell with most of the original pumping equipment long gone, into a delightful five bed-roomed, three bathroom home with huge living, dining and kitchen areas, a library/study and a design studio plus a large leisure/sports area in the basement.

PECC Engineers of Haslemere were called in to design the eco-friendly renewable energy system, using the two ninety metres deep wells which were already in the floor of the pumping station. These offered an absolutely ideal ground source for all central heating and water heating requirements. The PECC design called for the installation of piping filled with a mild refrigerant solution in the two bore holes, providing a medium for transferring the heat

permanently present in water, earth or rock below the ground’s surface, to a NIBE F1145 Heat Pump in the house’s Utility Room. The F1145 – one of NIBE’s new generation of super-efficient pumps – vastly increases the temperature of the liquid to 65 degrees Centigrade by a sophisticated heat exchange process before passing the energy into the house’s hot water system. The system has proved ideal, providing ample heat [with the help of a VP300 UKV Buffer Tank] for the under-floor heating installed throughout the Pumping Station and hot water for the family bathroom and the en-suite in the master bedroom plus all kitchen and appliance needs.

Since the energy passed into the hot water system is well over four times the electricity used by the heat pump itself, the energy savings created are impressive.

The NIBE hot water system is only one of Nutbourne Pumping Station’s energy saving facilities. The large roof area has a positive forest of photovoltaic panels superimposed on a sedum base and needless to say there is a full rainwater harvesting system as well as a high level of insulation applied during restoration which includes 180mm to walls and floor and 300mm to the roof.

Nick Sweet’s only non-essential energy source is a 13kW wood burning stove in the lounge area, which he admits is a comfort factor, not an essential heat source. www.nibe.co.uk Enquiry No 79
