EPS (Expanded Polystyrene) is a lightweight cellular material derived from petroleum and natural gas by-products. EPS sheets and boards are used extensively for thermal and sound insulation in

walls, roofs, and on floors. Loose beads are used as aggregate in lightweight concrete, plasters and renderings. Other uses include under-floor heating systems, drainage boards, permanent formwork, foundation and prefabricated wall systems.

Low carbon footprint As thermal insulation, EPS saves up to 400 times the energy originally required to manufacture the base product.

No CFC’sEPS consists of organic materials, making it one of the most ecologically harmless products available.

Conserves energyThe excellent thermal insulation performance of EPS makes it an efficient and effective solution.

Easily DisposableCorrectly incinerated, 100kg of EPS leaves just 0,01kg ash and emissions are non-toxic.

Life Cycle Assessment (LCA)The Life Cycle Assessment from manufacture to disposal supports the

environmental impact benefits of EPS for sustainable building and development.

RecyclableEPS is recycled into a variety of products such as picture frames,

curtain rods, skirting and decking. It can also be broken down, mixed with refuse and burnt as fuel, or provide aeration which

assists in the breakdown of organic matter in landfills.

We refer to a letter written by "Donald Quixote" regarding the above.

The National Regulator of Compulsory Standards (NRCS) proposed the wording of Regulation X A to the Minister of Department of Trade & Industry. The regulation was duly published on 9 September 2011 and effective 2 months from published date.

The NRCS duly consulted with relevant Government departments, CSIR, Agrement, SAIA, CIDB, SABS, industry stakeholders and prominent Consulting Engineers prior to publication of Regulation X A for public comment. Comments received were duly considered prior to publication of final regulation.

Similarly SABS followed the same procedures in its drafting and publishing of SANS I0400:XA and SANS 204.

To state that one individual has influenced decisions in the above process to further industry interests is ridiculous and amounts to chasing windmills.

Yours faithfullyAAAMSA

“Ninety-nine percent of houses in South African surburbs do not comply with the new building regu-lations relating to energy efficiency (SANS 100400 XA 10 November 2011) that have come into force. For example, if the surface area of glazed windows and doors of a house exceeds 15% of its floor area, you now have to do a detailed set of calculations per room: orientation, overhang of eaves, types of glass, the window-frame material - all of which feature in the calculations “to save energy loss”. To comply with the new regulations, the owner, must install thicker glass, double-glazing, even double-glazed sliding doors, which will push up the cost of houses dramatically. Who will benefit?

Bernice Baily, writing on the glass manufactur-ers’ building industry blog site “Design Mind” (on 18 Nov 2011) reports: “Our Technical Manager, Mike Pote, said that Glass South Africa, (linked to the PG Glass Group) were directly involved in compiling the new regulations” Two independent guys in the glass industry told me this was set up by Hans Schefferlie to ensure huge profits for the industry. (He is also involved in the insulation industry.) Recently I attended a seminar in Knysna by Hugh Fraser (ex-PG Glass) on the glass regu-lations. He tried to make light of the new rules, but said something that worried me: in the new insulation regulations, one requirement matched-to the decimal point-the product of a particular local insulator! (French multinational Saint Gobain’s product Isover.-Ed) This stinks. It could be the biggest money-making scam in the history of South Africa’s building industry.

And if you’ve bought a plot at the seaside and are dreaming of all those brilliant sea views, forget it: regulations require that your house must face north, even if all that offers you is a perfect view of the neighbour’s long drop. The authors of these regulations cribbed them from Australia, where most homes are air-conditioned, and clearly did not apply their minds to our conditions and how we live.

I support energy saving. We can reduce the amperage in our house by changing to solar water-heating, cooking with gas by having our distribution boards modified, by installing relays that switch off geysers when the stove or oven is on. We can insulate the roof and plant deciduous trees to screen us from the summer sun. We can use energy-saving bulbs.

We can install Trombe walls (designed for thermal storage and delivery) to heat our houses for nothing.

But the additional cost of complying with new regulations will ensure few houses are built and yet more jobs are lost. And don’t do any alterations as you will have to change all your windows to comply with the new regulations. The South African architectural institutes have done nothing about these regulations, as most members are not even aware of the implications Architects, it seems are a pretty dumb bunch of professionals and too chicken to stand up and fight for what is right.

COVER STORY

When Gwynneth meets up with “Archi-tect & Specificator” she tells us that it didn’t take long for them to decide that they were encountering doors so

badly made that they decided to make their own. The endeavour soon became successful enough to provide work for most of the family and an environment of nurturing creativity.

Innovation This has led to some innovative products, most recently the PRO range. Designed by brother, Ga-reth Andersen, the inspiration came from a small section of folding panel. “He saw that it could be used as a roller garage door clad with safety glass,” explains Gwynneth. The result is a high spec, high tech rolling mirrored door that looks at home in the most architecturally avante garde setting.

“He took the existing profile and adapted it to be more workable. It took a couple of years of R&D to get the right balance of weights and brackets; safety glass is much heavier than the materials usually used for garage doors,” she continues.

It was worth the wait. The doors are sleek and sophisticated, and boast the added advantage of low maintenance. “Unlike most garage doors, there’s no sanding or varnishing; you simply wash it like a window,” smiles Gwynneth.

While clear glazing is an option – and would probably be favoured by exhibitionists hoping to display their high-end vehicles, she explains that they prefer reflective options since it’s a better way to conceal the frame behind.

There’s more Not content with one ground-breaking new product, Gareth and his team have also designed a weather-tested range of folding doors that have earned an A1 grading by AAAMSA. “They’re top-hanging for ease of use, but that doesn’t affect their energy-efficiency,” Gwyneth tells us. “They look frameless, but are still strong and weather-proof. Our garage doors also offer maximum solar energy control,” she continues.

With beauty, functionality, safety and energy efficiency covered, it seems that Image Glass has ticked all the boxes with these products. We look forward to seeing what they’ll have up their sleeves next.Gwynneth Andersen, Tel: (011) 914-1363, Fax: (011) 914-4987, Email: [email protected], www.imageglass.co.za

A family-run business, Image Glass was established by patriarch Chuck Andersen in ’96, when he started repairing

doors for clients. Business was good enough to bring daughter, Gwynneth Andersen on board soon after.

“Architect &Specificator” recently spoke to Frank Jaucot of FJ& Associates Architects for some insight

into surviving in a diminishing work pool. “It’s true that big projects are not as plentiful as they were in the past,” Frank admits. “Apart from budget constraints, companies are also at the mercy of lengthy approval processes – we’ve had big proj-ects completely shelved because clients have become frustrated after years of waiting for (rezoning and) plans to be passed. But this has opened up some interesting opportunities in other spheres.” Corporate refurbishment has

Big projects completely shelved because clients have become frustrated after years of waiting for (rezoning and) plans to be passed

In a climate of corporate belt-tightening, large-scale greenfield projects are

becoming the stuff of dreams. This hasn’t stopped architects from putting out some highly creative work, however. In fact, the area of refurbishment often requires more

creative thinking.

Residential projects are a valuable income stream during quiet times

Frank Jaucot, FJ & Associates Architects

become something of a speciality for the practice and it’s a challenge Frank appears to relish.

Retrofit for businessHaving cut his teeth in the Joburg architectural scene in the ‘90s, Frank opened his own firm in 2005, focusing on commercial work. Retrofits and industrial projects soon became a focus, with the occasional foray into residential for a change of pace. “All of our work has been due to referrals,” he tells us. “Usually someone will see one of our projects or speak to one of our clients which leads to something similar.”

It’s not hard to see why this would be the case; while most firms will display pages of high-glamour, high-end projects in their portfolios, it’s not easy to find an architect who will design a green car-wash. “We just completed the main car rental storage and despatch facility for Avis Rent a Car in Gauteng,” Frank tells us. “The company is very sensitive to environmental issues and their requirements were very stringent to ensure the highest possible environmentally sustainable facility.

“We used recycled water, as well as water harvested from roofs to offset carwash water consumption,” he explains. “In doing this we were able to make savings of up to 70% water usage. This is con-siderable when you consider that they wash up to 1200 cars a day. We also redesigned the layout and flow of the refuelling facility – which now has 14 refuelling lanes – all in order to maximise efficiency and traffic flow.”

Good thinkingOffice refurbishments draw just as much enthu-siasm from Frank and his team, and some have budgets not to be sniffed at. “We recently worked on a project for Barloworld Automotive in Isando,” he says. “The company took over a seven-storey

building that had virtually been left untouched since the late ‘70s. We were really excited because it involved a total refurbishment of a building in an area not known for its lovely architecture. Barloworld Motor took the bold step to invest in the area and it’s now their head office.

“Not only do they have a beautiful building, but it’s also an excellent facility that serves them very well. There’s more than one aspect to what we do. We’re not just designers; we get involved in the technical aspects too. We don’t simply create a pretty building; it has to be a working building that will serve the client’s needs for years. It must be relevant and sustainable. It’s not often that you’ll find a client who has the insight and the financial muscle to do something really special,” he smiles.

The Barloworld refurbishment was started while the building was still occupied by the previous tenants, which brought its own set of challenges. “We were working with a typical ‘70s building that was ugly and awkward,” Frank describes. “Every window was shaded by precast canopies and there was an original internal courtyard which had been bastardised to include an entertainment area complete with tatty thatch lapa, spit braai and concrete garden furniture. It was horrendous! The existing canteen was redesigned completely and now properly relates to the courtyard as op-posed to the original with its pastel curtains and dingy interior.

“We stripped the building completely and gave it an aluminium façade, which made an immedi-ate difference. We demolished all the horrible

Improvements included new vehicular entrance with guard-house and increased parking facilities

additions in the courtyard and returned this to a beautiful and tranquil space and converted the old private dining area into common meeting rooms which overlook the courtyard. Luckily the original concrete structure of the building was very good, although sections of the concrete façade had to be repaired. We completely stripped all the office floors and refurbished them with a combination of open plan and perimeter offices. Central toilet blocks were refurbished and wasted space in lob-bies was used to create shared meeting rooms. The old double volume ‘raadsaal’ – complete with ‘70s wood panelling – was upgraded to executive offices and boardroom and the wasted double volume space was converted to archive storage.

“We also turned the old caretaker’s quarters on the top floor into a company gymnasium with a magnificent view,” he continues. Other improve-ments included new vehicular entrance with guard-house, increased parking facilities and an efficient airconditioning system. “The aircon was a problem because the original system was antiquated and relied almost exclusively on inefficient console type units. So we incorporated energy-saving inverter type units. The building had not been designed for a central ac system so we had to make use of some creative pipework routing through the existing toilet ventilation shafts.”

All in all, the project has been hugely successful. “The building now works,” says Frank. “I think it’s one of the best redevelopments in the area. It was great to take a building that was in such a sorry state and transform it so completely. It took real vision from Barloworld to put so much faith into the area.”

Balancing actWhile FJ& Associates has found a way around the current downswing in business, Frank acknowledges that the economic climate has had a detrimental effect on the way architects conduct business. “I guess you could say we suffer for it. Every project now involves a lot of haggling and trimming of fees, and ultimately there’s a dilution of the real craft of architects. There was a time when we’d design, project manage and see the job through to completion.

“Now many clients simply ask us to submit a design, which they send to tender. Often they’ll negotiate the project with various contractors themselves and try to project manage the process internally in order to save costs. It’s troubling because sometimes it results in an inferior product – often the project doesn’t even look like your original design at the end of the day and you’d be amazed how often we get called back to help rescue things when ‘cheap’ contractors have caused problems,” he cautions. “Unfortunately you generally get what you pay for!

“The authorities are cracking down on this, however, since regulations now mean that the architect must

see the project through to completion for the sake of accountability. This is good for us, but adds a lot of paperwork, which takes us back to the plan approval process, which is shockingly slow.”

SustainabilityDespite his tone, Frank has faith in the system. “The application of new regulations and specifi-cally the requirements for a higher environmental conscience will be good for sustainability in South Africa,” he emphasises. “I’d like to see government incentivise the practice more to encourage take-up.”

While there are some incredibly capable people making these decisions; it’s the application that’s the problem. “Municipalities are relying more and more on indemnities rather than inspections. Regulation procedures are more complicated but they’re leaving responsibility for compliance on the shoulders of the professionals and developers. I think that the authorities need to be more techni-cally proficient in the application of the building regulations and specifically the newly introduced environmental requirements. We have found that corporates are a lot more stringent about meeting the requirements from a social responsibility point of view but in the residential market, things can be pretty bad, which is a pity because ultimately the regulations are there for the benefit of all,” he ends off.

Fit for purpose?He goes on to say that there are products on the market with Agrément certificates that are ap-proved fit-for-purpose that don’t necessarily meet current regulations. The testing process described

on the Agrément site appears suitably thorough, with assessment criteria being defined, testing and evaluation conducted and external experts subcontracted. Quality control should ensure that current standards are met, but it would appear that there may be a flaw in the system.

Hans refers us to certifica-tion for a concrete win-dow frame that contains numerous discrepancies. “They mention the NHBRC Home Builders Manual, which I believe has been rendered redundant by the National Building Regulations, which rely on SANS 10400 to prove compliance,” he explains.

“There’s also reference to Wispeco, who had nothing to do with the product in question. And they cite SANS 727 for steel door frames, but this certificate is specifically for concrete frames; it doesn’t seem relevant!”

Other points of concern include the statement that the products are combustible in respect of SANS 10177-5 and 9, despite the fact that

Little Room for Error“The Agrément certificates require revision,” Hans Schefferlie, Executive Director at AAAMSA tells “Architect & Specificator”. “Pretty much all of them state they are in compliance with the building

regulations of 1990. But the regulations were totally revised in 2008. Are tests being conducted according to the correct regulations? Agrément tests unusual items for specialised functions, so this is particularly

important.”

FINDINGS, SPECS & REGS

Hans says:By 2020, SA will be the warehouse for foreign material producers and we’ll only have our-selves to blame because we think we’re too busy to plan properly.

Page 14: Architect & Specificator July/Aug 2012

Page 15: Architect & Specificator July/Aug 2012

13Architect & Specificator July/August 2012

SANS 10400-T deems aluminium and glass to be non-combustible materials. A request for copies of tests done according to SANS 10177-5 and 9 is pending.No progressWhile the matter was raised with Agrément, and a response was received noting these concerns, nothing has yet been done to rectify the situation. “A letter from them signed in August 2011 still refers to the 1990 regulations,” he emphasises. “The latest copy of this product’s certification, downloaded on 9 May 2012, does not appear to show any changes either.

“You’re paying thousands of rands for that report; it must be accurate! My call to them is to please review all of the certificates. Some of these items can literally endanger lives, so it really isn’t something that can be postponed,” Hans says emphatically.

FINDINGS, SPECS & REGS

Hans says:There was a 23% decline in business in 2011; how many companies are preparing for more downturns in 2012? Most people are looking at tomorrow instead of next week.

Hans says:Most people don’t realise that while China is capable of producing high quality products, when you start bartering their prices down, they lower the specifications.

No room for errorWith its goal of being internationally acknow-ledged as the South African centre for the assessment and certification of innovative non-standardised construction products, systems, materials, components and processes, expec-tations of Agrément leave little room for error.

The organisation also aims to adopt a holistic view when testing products, factoring in technical, commercial and social factors such as economic viability, cost benefit and consumer acceptability.” It is important that the organisation test according to current standards,” Hans emphasises.

Six international architects, including Kibwe Tavares and David Adjaye (UK), Atelier Bow-Wow founders Yoshi-haru Tsukamoto and Momoyo

Kajima (Japan), and Tatiana Bilbao (Mexico), will join a host of innovative South African architects as speakers at the Architecture ZA 2012 Biennial Festival, to be held at Cape Town City Hall, from 16 September.

In partnership with the South African Institute of Architects (SAIA), Cape Town Institute for Architecture and associate sponsors PPC, the Cement and Concrete Institute, Lafarge and Paragon Architects, the festival is a veritable think-tank of international and local speakers, that also includes debates, master classes, exhibitions, a film festival and city tours. Architecture ZA 2012 follows on the success of the 2010 Biennial, which took place in Newtown and attracted more than a thousand delegates.

‘Rescripting Architecture’ is the theme for this year’s event and the festival runs in conjunction with the annual Student Architect Festival, and also serves as the setting for the announcement of the

winners of the biennial SAIA Corobrick Awards for Merit and Excellence, the ‘Oscars’ of the architecture industry. In addition, the festival kicks off the official Creative Week Cape Town and is an important event leading up to World Design Capital 2014.

The festival’s theme is a considered response to challenging times and a world increasingly in flux, with rapidly changing global economies, environments, and political situations, according to Festival Convener, Daniel van der Merwe.

“In the past, architecture has played an important role in shaping our landscape, but now, with the world population shifting to cities and increased pressure on resources, we need to start think-ing of architecture as a provocateur of change,” says Daniel. “More than ever, architects must play their role in creat-ing better environments for the future. This festival, with its collaboration of architectural and cultural minds, is not about creating pretty things, but is about asking serious questions and pondering our collective future.”

INSULATION

As the biggest single optical telescope in the southern hemisphere, SALT is a significant scientific project for South Africa and is a similar, but improved version of the

HET facility at the University of Texas’ McDonald Observatory near Fort Davis, Texas.

The provision of modern and comfortable ac-commodation, recreational and administrative facilities are of prime importance to enable both researchers as well as technical support teams to live and conduct their work at the observatory in an extreme climate. Sutherland is alleged to be the coldest town in South Africa. This claim may be challenged by other places such as the Molteno district in the Eastern Cape, but the clear nights of Sutherland often experience temperatures way below zero - perfect for observing the universe but very unfriendly to humans.

To maximise optical performance, the entire SALT telescope chamber is cooled from 12 noon down to the anticipated temperature at civil twilight (sun at 18 deg below the horizon) when the dome is opened.

No cosy firesCreating comfortable living conditions in an area where cosy fires are forbidden due to smoke par-ticulate emission means heavy reliance on national grid power, backed by emergency clean burning fuel oil generators on site. The observatory is a direct consumer of Eskom power which is charged at the Ruraflex rate. This means peak rates of close to R3 per kWh dropping to 40 c/kWh during off peak low demand seasons. Heating in the accom-

modation blocks, houses and other spaces such as office and recreation centre is by large electrical heating panels that consume approximately 25 kWh each per day in the peak demand season, contributing substantially towards an overall site energy consumption of 145 000 kWh per month in the season

SALT electrical engineer, Keith Browne and mem-ber of the SAAO Energy Saving Committee, rose to the challenge of reducing consumption at the SAAO complex. With power bills of R 155 000 per month during winter, it became a necessity to control budgets and also meet the national energy-saving imperative.

UnnecessarilyUpon inspection of the relevant areas, Keith found that loss of heat from the main buildings was unnecessarily high owing to loss of energy from the roof. One of the most visible causes of the problem was the drop in efficiency of glass-fibre based insulation that was installed in the older residences at the time of construction, approxi-mately 30 years ago.

Typically, products that contain dense fibre ma-terials bonded together by resin tend to degrade and collapse over time. They trap dust and other particles entering through leaks in the roof space, typical of most South African roofs, therefore compressing further and losing R-value, explains Richard Ellis, a Cape Town-based expert in ther-mal efficiency.

“During summer, when rooftop temperatures can easily reach +50º C, the reverse occurs, mean-ing heat enters the building and power-hungry airconditioner units have to be cranked up to cool the building”, he says.

In the Stars A major consideration in the design and ongoing operation of a large observatory such as the SAAO in Sutherland, where the Southern African Large Telescope (SALT) is located, is the comfort of the observer and resident technical maintenance and support staff.

INSULATION

No-nonsenseRemoving layers of degraded glass fibre insulation is a tough job, which should be undertaken by adequately trained personnel with personal safety equipment and an approved plan for disposal. “Such fibres are notoriously difficult to handle and should not be touched with the unprotected hand”, he adds. “Operators also wear respirators to protect their airways from loose fibres”.Ellis is an approved installer of cellulose based loose-fill thermal roof insulation, Eco-Insulation. Founded in 2005 by Cecil Homan, the company has achieved great acceptance in the professional and domestic market as a no-nonsense supplier of a green product that achieves excellent energy-conserving results and supports the sustainable building imperative. It was honoured by the Southern African Energy Efficiency Association with their “Company of the Year” Excellence Award during 2008.

Non-negotiableThe cellulose product was ultimately chosen after going to tender and due to its superior insulating characteristics, ease of installation at 100% coverage and cost effectiveness. Having SABS approval and being fire rated in line with the national building standards, was also non-negotiable.

Subsequently Eco-Insulation was installed by the Ellis team over a two-week period in the SALT workshops (a notoriously climate-exposed loca-tion), in all accommodation areas, the office area and also in parts of the recreation centre.

“Best estimates show that the energy saving is significant – close to 180 000 kWh per annum”, says Keith. “We will be running observations over the ensuing months to get a more accurate picture,

but this installation will save the SAAO hundreds of thousands of Rands over the years. – payback will be over two years. Our insulation, together with other initiatives, has currently resulted in an 11% monthly cost reduction growing to a signifi-cant 20% in the winter months. What’s more, it is considerably more comfortable than before”.

D r Llewellyn Lewis, Principal Consultant of BMI-Building Strategy Research Unit, says, “In its quest to prevent collusion, it appears that the Competition Commission

is taking South African business into a McCarthy-style era in which, instead of finding a communist under every bush, they are seeking collusion behind every door. The timing of this decision could not be worse for the industry, as the strategic importance of this data is enormous.

“One has to question the motive of the Competi-tion Commission when continuing to withhold such crucial strategic information. Are they really seeking evidence of collusion? Industry players must speak out to ensure that the Competition Commission does not mistakenly wield its power to hoard information.”

In real timeAccording to Llewellyn, these statistics have been available for decades but their value as the most current and reliable source of information on building and construction has only recently been acknowledged. He adds, “These statistics have been published, albeit in a scattered form, since 1892. Two years ago, people suddenly realised that these statistics constitute the most current and reliable indicator of building activity, because cement is the most widely used construction material. Hav-ing this information affords companies the ability to plan their capacity in real time synchronisation with market activity, making them a significant planning tool – not a marketing tool.”

To date, many industry stakeholders have made representations to the Competition Commission, requesting for the decision to withhold this infor-mation to be reversed. These representations have made explicit ‘that the data provides information on volume and end-use product broken down by province’, and does not refer to pricing or market share.

Thus far, the Commission’s only response to these representations has been a series of ‘telephonic interviews’ that were ostensibly aimed at gauging how the industry uses this information.

Critical indicatorsLlewellyn says, “The aspect that is most worry-ing is the lack of any real action or a statement one way or the other. Keeping an entire industry in limbo as it fights for its very life is destructive and incomprehensible. The data cannot possibly be seen as collusive because it provides no in-formation on pricing, market share, profit of the various suppliers, or any other information that could even remotely be used to collude on pric-ing or market allocation. Withholding it is akin to banning the publication of statistics on car sales or mortgages advances, which have long held up as critical economic indicators.”

Llewellyn explains that experts have analysed the information in different ways and presented it to clients in a manner that added to their strategic understanding of the context of the construction industry. For example, this analysis revealed and made common knowledge, for the first time, that cement is the major building product group, ac-counting for some 16% of the total. Therefore, it became apparent that cement sales is a proxy for the activity of the total building and construc-tion industry. According to Llewellyn, there is no other statistic that functions in this manner and, because it is available within 10 days of month end, instead of months later like other data, it is the most current.

In LimboThe Competition Commission’s decision to prevent

the centralised publication of cement usage statistics, on the grounds of alleged collusion by the cement manufacturers has robbed the construction industry of the most up-to-date

information on building and construction activity. The lack of information and resulting impact on

forward planning has come at a difficult time for the beleaguered construction industry.

The mind of an architect is a little divided,” he smiles when we ask whether architects are artists or scientists? “According

to the Guiness Book of Records, architecture is one of the hardest courses to study because it requires both left and right brain functions to facilitate the integration of the logical requirements with the aesthetics of architecture.

“I always tell students that Architecture is your third skin,” he continues. “There is tremendous power in the psychology of space. We have the ability to make people feel comfortable…or uncomfortable, simply by the way we devise a space.”

In Daniel’s opinion, Architecture is the mother of all Arts. “A house is an expression of Self,” he explains. “The first creative act of a child is to draw. And he draws himself and his home. For an architect, this becomes second nature. When people talk to me about feng shui principles, I can’t help smiling. A good architect will intuitively know how to apply methods to create this impact. Since we’re taught to marry logic and art from the start of our studies, it is natural to apply rationalism to aesthetics. A good architect will intuitively design spaces to be in harmony and which will be proportional,” he emphasises.

Some of the most creative people in history were considered socially or even intellectually dysfunctional

Daniel van der Merwe, an architect with C&CI, who is tasked with promoting concrete as the versatile and contemporary material it is, has become well-known in the industry. “Architect & Specificator” recently met up with him to share his thoughts on architecture and the world of design.

Italian Pavilion, Shanghai Expo: High performance composite concrete allows for ultra-thin precast translucent wall panels

Skyscrapers and sewersSo do all students start their careers hoping to create magnificent structures, or are there those with less grandiose ambitions? Or are some simply compelled to opt for low-glamour projects to pay the bills? “A lot of students don’t really know what architecture involves,” explains Daniel.

“The level of academic achievement required as part of the entrance requirements at many universities already eliminates many potential candidates. In a way it’s a pity because many of them could become brilliant designers. Some of the most creative people in history were considered socially or even intellectually dysfunctional in society.”

This may be problematic in an arena which could use more architects. “I don’t think it’s possible to oversubscribe the field,” says Daniel. “Statistics show that there are 2 500 architects in South Africa, compared with 16 500 engineers. We have far fewer than other countries. For example, in Mexico there are over 25 0000 registered architects. And for those who don’t thrive in the industry, the studies prepare them for so many other careers, from fashion design to site supervision.”

Young culture Daniel believes that the way a society treats its creative talent is an indication of its maturity. “In older cultures artists, poets and architects are revered. This says a lot about a society. I think South Africa is still a developing culture, and it sees its architects as a luxury, which isn’t the case. A good architect will maximise design input and minimise capital outlay, rationalising a design to

provide a better and cost effective solution and create better collective urban environments to the benefit of all. It is startling that only about 14% of all buildings in South Africa have been designed by architects. The bleak, ugly and wasteful urban environments of our country are a result.

“But many would rather go to a technician to have their plans drawn up, which doesn’t make sense. You wouldn’t go to a pharmacy for a surgical procedure. Anyone can cook a meal, but that doesn’t make them a chef. Your home is one of the biggest capital investments you’ll ever make; surely it should be treated as such?”

Chicken and eggIn rationalising the design, many plans will incorporate new technologies to provide best ‘bang for buck’. We’re curious to know who drives the process: does the architect push for new methodologies or is he or she driven to use what becomes available? And are architects more inclined to take the leap into new territory than other professionals? According to Daniel it’s a combination of factors.

“There’s invariably cross-pollination between the different disciplines, which I find fascinating,” he smiles. “NASA space research might produce a material with construction applications, so we use it. Where architectural influence comes in is in areas where a need pushes development. For instance, as the demand for green products or energy efficiency grows, it drives development of new technology, so in essence, market need has determined technological advancement.

“The two still work hand-in-hand, however. Take the Media Tic building by Cloud Nine in Barcelona, for example. It’s a super responsive building that reacts to its environment. It utilises a paint that absorbs solar energy and glows at night thereby reducing the need for electrical lighting; gas is introduced through a central monitor to manipulate the extent of insulation, which allows the building interior to be heated or cooled down in a passive way and without the need for mechanical ventilation. Five years ago, this would not have been possible. Now that the technology is available, we can go for it. But the technology wouldn’t have developed if we hadn’t needed it. It’s a chicken and egg scenario.

“In these cases, architects are more inclined to take up new methods than others might be, but it’s a calculated risk. Remember you’re working with someone else’s money, and if something goes wrong, who pays? But if the benefits are apparent, then architects and clients will rise to the challenge. High performance concretes are a good case in point. As more examples of built projects using it become available, there’s more acceptance. It’s probably hardest for the real trendsetters, but someone’s got to take the first step,” Daniel acknowledges.

Only about 14% of all buildings in South Africa have been designed by architects

Punitive measuresThis leads to the topic of getting new methods approved. Are new architectural investigations often stymied by restrictive legislations, and is there the perception that governing bodies are applying punitive regulation to corner the market for their own products?

CONCRETE & CEMENT

Page 26: Architect & Specificator July/Aug 2012

“In a way, yes,” he responds. “Some legislation is impractical, applying first world rules to a third world country. Enforcement is heavy-handed and it’s going to cause problems down the line. For example we have a great housing need, but certain regulations of the SANS 10400 will increase the building costs forever beyond the reach of lower income people. I think the intention is right. We’re all morally bound to do something. However, good architecture should be a sustainable and responsive architecture.”

So do all architects have good intentions or do some have to be forced; what works better, the carrot or the stick? “We’re taught these basic responsive design principles in our studies – a first year student who builds a west-facing glass building will fail. The reality of market forces will probably compel change anyway. I’m not sure when we decided to build glass skyscrapers in the deserts of Dubai; perhaps cheap energy made us careless about the need to be conscious of climatically attuned buildings. But this has changed.

“In some instances, the carrot will work – Green Star ratings and the like. In other cases we will be compelled by the legislative, the SANS 10400 stick…but the economies of market forces will always remain the biggest incentive. I hardly see a building going up that doesn’t conform to some sustainable design principles. The clients demand it, because it makes sense in money terms,” Daniel emphasises. It is not only about the initial building costs, but also the lifespan and lifecycle costs, the energy and maintenance costs of a building. “This is what makes concrete such a fantastic material. It is maintenance free, durable, recyclable, and has fantastic thermal massing qualities. But hopefully conscience plays a role too. They say if you’ve ever seen a rainforest cut down to the ground, you’ll never think of a wood-paneled boardroom as beautiful again. We have to think of the future of our planet, and everyone must play a role in preserving it for the sake of our children.”

Green gets red lightWhat of those who find their efforts to push the green envelope stifled by municipal red tape? “Some of the more progressive techniques can’t be applied everywhere,” says Daniel. “Our legislation in this regard is more lenient than we think – in

Europe it’s far tougher. It’s unrealistic to hope to build straw bale houses with composting toilets in a city. But that shouldn’t be an excuse not to apply sustainable principles.

“The principles of traditional or vernacular architecture are timeless and they work. Correct building orientation, siting on a site, using appropriate and local materials, wraparound verandas and using roof overhangs to manipulate the sun angles, using natural ventilation etc…there was a reason for these things because they evolved out of necessity. I have an old house in the Eastern Cape with thick walls, small windows, shutters… I was there recently when the outside temperature dipped to -5°C, and it was toasty in there!”

Public voiceWhile Daniel doesn’t claim to speak for the profes-sion as a whole, many of his ideas mirror those of his colleagues, which bodes well because he has a lot of passion for the built environment. He considers concrete to be the building material of the future – in fact civilisation would not have been possible as we know it if it wasn’t for this wonderful

Innovation #7

Page 29: Architect & Specificator July/Aug 2012

27Architect & Specificator July/August 2012

In an attempt to try and eliminate mountains of un-recycled plastic in Belgium, an innovative idea came about to manufacture roof tiles using

this material. The first tile was produced in 2000, followed by required testing in laboratories in Germany to improve the UV and impact resistance of the tiles.

Through development and testing, small solar panels were later incorporated into the tiles, resulting in a power generation product for roof space.

The Sun Roof Tile is an architect’s dream for incorporating renewable energy into a building without compromising the aes-thetic appeal of the design. The product is light, moss resistant, which is an issue in Europe, has high heat and impact re-sistance, is easy to install and fault-find, with the only compromise being a reduced efficiency (Wp/m2) when compared with conventional solar paneling.

Development through testingStandard testing was undertaken in Germany where ice and hail blocks were hurled at the tile at various velocities. The specific resistance of the tile was then measured

and the results showed that the tiles were UV, water, frost and hail resistant.

However, the tiles originally were only manufactured in black, which caused excessive heat generation. In an attempt to limit the heat transfer in summer to the rest of the house, a decision was made to build ventilation channels inside the tile to provide natural cooling.

Another solution designed around the heat problem was to capture the heat at the apex of the roof and direct that heated air to a heat pump to improve its efficiency, as well as utilising it for home heating applications.

Improvements for a viable solutionIn appearance, the Sun Roof Tile looks similar to a normal ceramic tile and the first roof projects were completed in Belgium in 2000. But the payback period of these projects was fairly long – at around 10 years – and it was therefore decided to integrate a PV panel inside the tile. Now the tile has three different functions:

• The roofing structure,• Hot air can be used for heating applications, and • Electricity generation.

The only downside of this aesthetic solution, compared with unsightly standard PV panels, is a reduction in efficiency when compared with a standard PV panel. This is due to the fact that the PV modules are encased inside the plastic tiles, resulting in a reduction in Wp/m2. However, on the upside, the integrated cooling system allows the PV modules inside the tile to be cooled quite efficiently as the cooling air flows through the channels behind the PV modules to the next tile.

What if your Entire Roof Generated Power?

Recycled plastic has been turned into a renewable energy generation product that serves as an aesthetic solution for architects to consider as an alternative to unsightly solar panels in building design, while using

recycled materials.

Tile constructionPhotovoltaic cells are silica based, amorphous and thin film. They consist of multiple layers with scale resistant tempered glass on top, then the actual PV cells followed by the black backing and wiring. Colours currently available are lavender, red, army green, yellow and black. The efficiency of coloured PV modules is approximately 25% less than black units.

As the roof contracts and expands during the day due to temperature changes, the connectors between the tiles need to remain intact to avoid bad connections developing over time. The actual link between tiles is kept stable and allows play through a spring insert.

Stainless steel is used as it is a good conductor and is corrosion resistant, but especially because it can be soldered. The PV modules have a double silicone seal and are pressed inside the tile, which acts as a support structure to the PV module. Each PV tile has its own connectors that clamp into the connectors of the adjacent tiles.

Installation Installation is extremely simple to execute. All the existing tiles must first be removed and if need be, the battens re-positioned as it’s critical that they run parallel to each other. The Solar Tiles are then laid, secured to the battens with screws and wired to the inverter. The minimum roof pitch required in Europe is 13 degrees. Typically, in Belgium, a standard roof installation of an average dwelling is accomplished within a day and the electrical connection requires a registered electrician’s services the day after.

Depending on the power management requirement of the installation, the whole tile field can be segmented into four or eight sections to enable active power management of individual roof sections.

Faultfinding is simplified as the tiles are connected in series in each row. The system allows only the affected tiles to be withdrawn from service for repairs

to be carried out when needed, which means the rest of the roof can still operate uninterruptedly. Each of these tiles is fitted with a bypass diode.

Coming togetherA number of different types of technologies had to come together first for the successful development of the Solar Roof Tile, including plastic processing, photovoltaic cells (finding small PV panels that would fit inside the tiles) and the connectors for the assembly of the tiles, as well as installation of cabling and inverters.

Alpha Power Solutions can now offer two different types of tile to the South African market: an 8 Wp and a 12.5 Wp tile. The first solar roof was suc-cessfully installed in 2007. The smaller version is the most common tile used in Europe with a peak output of about 70 Wp/m2. The larger ver-sion has greater efficiencies with a peak output of 120 Wp/m2.

As this is an aesthetic solution, the cost per Wp is higher when compared with standard PV panels, but it has other characteristics which might offer solutions to architectural design dilemmas.

A $1 billion (R7.9bn) city without residents will be developed in Lea County near Hobbs, New Mexico to help researchers test everything from intelligent traffic systems and

next generation wireless networks to automated washing machines and self-flushing toilets.

This project is being billed as a first-of-its-kind smart city, or ghost town of sorts, that will be developed on about 39km2 of land west of Hobbs.

Bob Brumley, senior managing director of Pegasus Holdings, one of the developers, said the town would be modelled after the real city of Rock

Hill, South Carolina, complete with highways, old and new.

No-one will live there, although they could, be-cause houses will include all the necessities, like appliances and plumbing.

The point of the town is to enable researchers to test new technology on existing infrastructure without interfering in everyday life.

For instance, while some researchers will be testing smart technologies on old grids, others might be using the street test self-driving cars.

“The only thing we won’t be doing is destructive testing, blowing things up – I hope,” said Bob.

Light Sculptures

To underscore the historic relation-ship between Mainz and Paris in an artistic manner, the technology group Schott produced two glass direction signs and presented them to the city of Mainz as gifts. One of the illuminated typographical sculp-tures points the way to the centre of Mainz while the other shows the distance to Paris. Both are located on a traffic island in the middle of Pariser Strasse in Mainz.

These design objects that are 2.6 m long, 60 cm high and 3.4 cm thick are made of a 3-pane glass laminate. The letters that spell Mainz and Paris were laser-etched into the inside glass layer, a 19 mm thick pane of white glass. The outer panes of the glass laminate are made of 6 mm thick sheets of “Amiran”, a glass that features an anti-reflective coating on one side. This coated special glass is known for its ability to minimise reflec-tions and thus makes it much easier to obtain a clear view of the letters. Dimmable power LEDs positioned 20 – 25 mm apart illuminate the display in the evening in a way that conserves energy. A special lamellae laser engraving technique allows for the letters to be illuminated evenly with high intensity and ensures that the objects retain their transparency.

of low iron glass for solar water heaters. Branded Prosun Solar, this patterned glass allows for greater thermal energy transmission when compared with clear glass. Lower iron content increases thermal energy transmission through the glass, so that it heats up the panel fins behind the glass, instead of be-ing absorbed by the iron in the glass. Local solar water heater producers

have responded positively to the introduction of this product, as domestic sales continue to grow exponentially.

“Our ability to successfully produce quality low iron glass has led to another development into glass that it is suitable for use in photovoltaic (PV) panels,” Bob continues. “Prosun PV has a higher light transmission than Prosun Solar, which

is critical for the performance of the unit. The PV panels are very versatile for applications of a few watts to power small remote installations; on top of buildings to generate power for own use; or in large installations to form power plants that can generate up to 100 MWs to feed into the national grid.”

Mirror and the sun In a new development, the company has announced that it is upgrading its mirror operation, to produce mirrors that can be used in concentrated solar power (CSP) plants and solar thermal electricity (STE) plants. These are expansive operations that generate electricity by using mirrors to focus solar radiation onto a receiver. The heat that is collected is converted to steam, which then flows through a turbine to generate electrical power.

Concentrated solar power (CSP)There are various CSP technologies in use around the world, and each has its own mirror design. “PFG is focusing on two technologies that require flat mirrors, namely Power Tower and Linear Fresnel systems,” says Bob. “These mirrors are designed for use outdoors and we are confident they should last up to 30 years even in harsh desert environ-

Green EnergyBob van Schelt, PFG sales and logistics director, says the company’s decision to be involved with

renewable energy, and particularly solar energy, is driven largely by the global realisation that renewable, ‘green’ energy sources are urgently needed. This is supported by the government’s Integrated Resource

Plan (IRP) that paves the way for future power generating plant construction.

ments. The volumes involved are significant: for every 100MW of power generated, about 650 000m2 of mirror is needed.”

To achieve the reflective properties and durabil-ity needed for CSPs, the PFG Mirror plant will be re-engineered to make what are known as copper-backed mirrors. These mirrors will have slightly thicker layers of silver and copper to improve reflectivity, as well as three layers of special paint (the current process uses two layers) to provide protection against the elements, temperature fluctuations, abrasion and UV radiation. Pro-duced in thicknesses of 2-6mm and a maxi-mum size of 3 660 x 2

CSP technologiesConsolidated solar power plants produce electric power by converting the sun’s energy in high temperature heat using various mirror configurations. PFG’s solar glass energy expert, Hugo Naude, explains that the heat is then channelled through a conventional generator. “The plants consist of two parts: one that collects solar energy and converts it to heat, and another that converts heat energy to electricity. CSPs can be sized in a modular approach ranging from village power to large-scale utility grid-connected applications,” he expands.

CSP plants concentrate heat from the sun to power a traditional steam turbine or engine to generate electricity through vari-ous systems that already are in use around the world. PFG’s expertise in flat mirror production aligns it well with two of these systems, namely:

• Powertower:Thepowertowerconvertssunshineintocleanelectricity,usinglotsofsun-tracking mirrors to focus sunlight on a receiver at the top of the tower. A heat-transfer fluid is heated in the receiver, transferred to storage tanks and then to a heat exchanger which generates steam, which is then used in a conventional turbine-driven generator to produce electricity. A 50MW project close to Upington is being developed.

• LinearFresnel:Usuallyusedforsmallerorremoteapplications,LinearFresnelcollectorsare line-focusing systems that have parabolic troughs in a fixed absorber position above a field of horizontally-mounted flat mirror strips, tracked to the sun either individually or col-lectively.

440mm, the technology, critical raw materials and quality standards are being supplied by international partners with extensive solar mirror experience.

The mirror plant upgrade includes the installation of a state-of-the-art copper recovery plant.

CompetitivenessAs the only local manufacturer of mirrors, Bob makes the point, “Our CSP-standard decorative mirrors will continue to comply with the interna-tional standard used for mirrors, DIN EN 1036. The same durability tests will still be performed, and current methods of handling, cutting, edge sealing, installation and cleaning remain the same. Installation and maintenance requirements also stay the same.

In fact, the only thing that will change from a building market, end-product perspective is that our ‘new’ mirrors will be even more durable.”

PFG MD, Jurgen Kruger, believes the company’s ability to manufacture and supply PV and CSP glass solutions is a boost for localisation. “In pursuing all current and potential CSP opportunities, we will cre-ate additional jobs directly, together with procurement options for local suppliers into the sector as well as downstream assemblers and manufacturers. We will also contribute to R&D and knowledge capac-

ity, thus enhancing South Africa’s tech-nology position and competitiveness as a nation,” Johan expands.

Using the sun to produce energy is a pressing, ‘non-negotiable’ oppor-tunity for South Africa. The country has a wide, reliable sun belt that incor-porates most of the Karoo and parts of the Kalahari, providing at least 320 days of full or near-full sunshine a year.

Plans are on track to produce 3 700MW of renew-able energy to be channelled into the electricity grid by 2016. The South African government has thrown its weight behind a green accord that can generate as many as 300 000 climate-friendly jobs over the next decade – many of which will be in the solar water heating systems industry.

FLOORING

T he Hiperfloor system can be used for repairing rain-damaged slabs or worn and damaged concrete floors

as well as removing trowel marks and surface irregularities. A useful side application is the polishing of terrazzo and natural stone floors. If you are throwing your own concrete, Pieter suggests placing good quality stones in the top layer so that when the floor is ground, these stones are exposed, giving an attractive and decorative finish. If you want to get creative, you can lay granite into the concrete and create patterns or words when it is exposed.

The fastest growing There are 14 steps in the Husqvarna Hiperfloor process, from removing surface components such as residual adhesives to sealing and polishing the concrete surface. The process can be stopped at any point, depending on the client’s needs. These steps can be broken down into four distinct phases. Cleaning the floor removes any unwanted components like epoxy, paint coatings or ceramic

tile adhesives. The floor is then ground using 20 to 160 grit diamond tools. Polishing and sealing ensures an attractive high-gloss finish that is harder than tile and abrasion resistant.

Eduardo Pereira of Cutters is a dealer of the Hiper-floor system in the Cape. Among his many satisfied clients are specialist concrete flooring contrac-tors like Floor Grinding Services. He says, “The Hiperfloor system is a tough and durable system that uses premium quality products that produce superior results. The chemicals are easy to use and handle. The equipment is hard-wearing and renders high yields. Floor grinding and polishing is a specialised process that requires detailed knowledge. It is one of the fastest growing sec-tors within the construction industry worldwide.”

Mid to high glossThis technology, although relatively new to South Africa, is popular with architects and construc-tion companies overseas who spec it into their drawings. The Soccer stadium in Durban was commissioned with a ground concrete floor instead of tiling or ordinary concrete slabs. Factories, wineries, shops and high-traffic stadiums all benefit from ground and polished concrete floor-ing. Mid to high gloss polishes can be achieved, with high gloss a stylish finish in homes.

The Face of Flooring “You won’t see many tiled shopping centres in Australia, they only use polished concrete floors because

they have such a long lifespan, Husqvarna’s Pieter Smuts tells “Architect & Specificator”. The maintenance is easy, too. If you need to service your floor all you do is demarcate an area and start. Our Hiperfloor

system is dust-free and relatively quiet. We once did a four-day floor grinding exercise in a shopping centre without having any effect on their day-to-day business.”

Atlas Copco probably ranks high on this list. “Architect & Specificator” chats to Neville Stewart, Business Line Manager – Construction Technique.

Principle areasHe explains that the construction sector has become so vast that Atlas Copco management decided to give the construction division its own identity, with an emphasis on portable technology, road construction and construction tools, such as demolition equipment, handheld compactors and concrete equipment, under the name Construction Technique.

There is also a construction tool service which

is designed to optimise equipment use. “This division is all about making sure we supply the correct parts when they’re needed. We’re working towards automating the function to keep things running smoothly. Most parts are stored in a central warehouse in Belgium, which provides 7-10 day delivery, but our aim is to provide 95% delivery within 48 hours,” says Neville.

Uninterrupted useThe biggest challenge to uninterrupted equipment use, is sourcing the right staff. “We need the skills

to manage each range,” he continues. “We want a specialist for every item and some areas, such as paving, for instance, don’t have many.

“For small, handheld items we have certified tech-nicians in the field who undergo constant training to keep them current. We also make arrangements with customers to maintain service levels and stockholding to keep them running smoothly – there’s been an 83% increase in business since we implemented the programme.”

“Clients have access to websites providing updated information, parts lists, solutions to problems and product suggestions for applications. Many South Africans are not used to this sort of resource, so it’s not fully exploited, but it’s becoming more popular.

Experience counts“There’s no replacing experience when it comes to construction. Most hand-tools are seen as consumables, but a hand-held can halt an entire project if it stops working. Specialists can tell you how external conditions might affect your tools – snow in Europe and heat in Africa will result in different performance from the same equipment. Even factors such as air density make a difference.

Our range is streets ahead in terms of environmental efficiency. Vibrations are reduced for safety. Noise is dampened to minimise hearing loss. From manu-

facture to disposal, our range is environmentally friendly,” Neville says.

“Construction in Africa has grown tremendously in the past 20 years. The challenge is to keep up with the times. We’ve noticed that projects are being split into smaller and smaller segments and more companies are popping up all the time. It allows people to start their own businesses and make a living. However, many have limited skills, so we try to supply tools with fewer parts, simple operation and easy maintenance.

“Traditionally we operate in the premium market with the guys who are committed to Health & Safety etc. We haven’t really catered to the one-man-show operations; we’ve always focused on long-term partnerships. We don’t want to fall into the trap of supplying cheap products to this market, we’d rather provide a lesser spec range to make it more accessible without compromising quality.”

In earlyIn terms of specifying equipment, Neville ex-plains that the team prefers to get in as early to do recommendations based on the application. “Typically we’ll be involved from initial contract phase, to working with procurement officers, to working on site.

“Once on site, we supply consumables and then our parts and service team takes over. That’s the scope of it, essentially. Obviously some projects are simple, others more complex. Some of this equip-

ment is capital intensive so it may take numerous meetings to get budgets approved.”

Solutions-drivenHe goes on to explain that theirs is a solutions-driven range. Products comply with Health & Safety regulations as well as emissions and energy consumption requirements. “We’re also about quality, availability and efficiency,” he adds. “For instance, we supply a plate compactor that’s 30% faster than our competitors’. It’s also easier to use; the compactor operates using buttons marked with understandable illustrations. Three lights indicate the status of the task and give the operator time to move out of a completed zone. “You want guys to get in and out of trenches before the walls col-lapse on them,” he emphasises.

“In terms of project management, we’re able to assist with scheduling. We provide a client with a time schedule based on workload, products used and the scope of the project. It’s about looking at the application, giving a recommendation and providing a solution.”

New developmentsThe company also has several new products in the pipeline. “We’re bringing in a demonstration truck for customer events. A lot of our projects involve upskilling and we run a Merseta-registered

academy to teach about our product range in the construction industry. From next year we’ll be offering operators’ training courses for small hand-held equipment; these have drawn a lot of interest from the parastatals.

The company’s compactors are highly competitive

“We already have a compaction analyser simulator for our ride-on roller for training operators and we provide on-site training for our demolition equipment as well as several Merseta courses for certification on civils and mining equipment,” Neville adds.

Time for changeThe building industry has been tough but it’s inevi-table that things will change. “We’ll always need housing and infrastructure and our sales show that there’s definitely growth,” he smiles. “Our smaller items, traditionally linked to building, have been moving; the upswing shows a 30% growth in these products year-on-year. And we’ve seen a lot of big private projects in the mining sector – when they expand there’s always an influx of people needing housing. We’ve seen this in projects such as Lep-alale and Steelpoort. If you go to the right areas, the building industry is alive and well.

“Something that we’ve also become aware of is that in built-up areas, if you plan to build, you have to demolish first; but you can’t blast so items such as hammers are needed. This opens up a new area for growth and we already have excellent ranges to meet these needs. Although the demand hasn’t grown yet, I’m curious to see how it will develop in the coming years, particularly with land becoming increasingly scarce.

“Atlas Copco has been around since 1873…we’ll be 130 years old next year. You don’t stick around for that long if you’re not serious about the right things – development, people, the environment. I think we’ve got the recipe for success,” Neville concludes.

A l t hough e x t e r na l s un diffusers are commonly used internationally, the benefits are not well known in South Africa and thus they are less commonplace.

“While most installations in South Africa utilise steel external sun diffusers, unless they are corrosion-protected and constantly maintained, they can start looking shabby after a short period of time. This, combined with a lack of education on the bottom-line savings produced by sun diffusers, are the most common reasons why they have not gained popularity in South Africa,” says Glen Pringle, fabrication director at Vital Engineering.

“We have developed a Vitaglass range of GRP fibreglass external sun diffusers which eliminate the inherent corrosion potential problems associated with using steel while adding a number of further benefits to the equation,” Glen adds. “Our chosen material of construction is much lighter than steel and because it is moulded, is therefore generally much easier to manipulate to suit specific building designs. On a weight-to-weight comparison, it is also more affordable than steel.

“Because we treat the Vitaglass diffusers with UV stabilisers during the manufacturing process, we are able to increase the durability and longevity of the product, which naturally makes it a viable economic option due to decreased

“We consult with architects and clients to establish their particular requirements and find workable solutions. This also applies to the choice of colours so, within reason, we can provide variations on our standardised red, green, yellow and orange offerings. In many instances, the colour is dictated by corporate branding or by the overall design specifications of the architect,” Glen explains.

While some clients prefer to install static external sun diffusers, Vital Engineering does receive requests for diffusers than can be elevated and lowered, either manually or automatically. “Once again this is installation-dependent and while we do not provide the mechanisms for the diffusers, we do provide products that are suited to this purpose,” Glen concludes.

A new Dischem Store had been planned as an extension to Pietermaritzburg’s up-market Liberty Midlands Mall. However, when it was discovered that the new suspended floor slab had a structural defect, PDNA Structural Engineers looked to Sika’s CarboDur system to solve the problem. The slab required external reinforcing for strengthening and increased load capacity, and it also had to meet the requirements for the shop services to be installed.

Sika CarboDur Plates are pultruded carbon fibre reinforced polymer (CFRP) laminates designed for strengthening concrete, timber and masonry struc-tures. The laminates are bonded onto the structure as external reinforce-ment, using Sikadur-30, a thixotropic, structural two-part adhesive, based on a combination of epoxy resins and special filler. Sika CarboDur Plates are non-corrosive and lightweight, providing

very high strength, outstanding fatigue resistance and excellent durability. Easily transported in rolls, the plates have unlimited lengths so no joints are required, have low overall thickness and are very easy to install, especially overhead.

Further advantages include: combina-tions of high strength and modulus of elasticity; minimal preparation neces-sary; and the pultrusion process ensures clean edges with no exposed fibres. The innovative Sika Carbodur Plates and Carbon Fibre Wrap systems, which are used to repair structural damage caused by fire, vehicle impact, and even earthquakes, boast worldwide endorsement, making the engineer’s specification for this project an easy decision.

Honeywell Building Solutions (HBS) has been awarded the contract to up-grade the South African Military Health Services (SAMHS) facility in Pretoria. Honeywell’s ability to integrate all solu-tions onto a single integrated building management platform utilising the Enterprise Buildings Integrator (EBI) system was a key factor for securing the project.

HBS senior account manager Kevin Pearman says, “The SAMHS site is complex and with security in mind, we were asked to present a progressive monitoring and access control solution in order to combat possible theft and unauthorised access. SAHMS included the following sub-systems to their In-tegrated Building Management system (IBMS): fire alarm detection; access control; IP CCTV surveillance intruder

alarms, gas suppression monitoring, UPS and generator monitoring; HVAC controlling and monitoring, irrigation control; perimeter detection; electric fence monitoring; video analytics; and a world-class Barco video wall to display all these technologies in three different control rooms“.

"EBI is a scalable and flexible solution, hence we were able to tailor the system to SAMHS requirements, providing a cost-effective open platform enabling all installed technologies to communicate with each other“ adds Kevin.

Colonel Gideon Odendaal from SAMHS adds, “Our facility here in Pretoria had old and outdated systems. As a result of the tender process I believe that HBS offered us the most progressive and competitive solution from finance through to network integration and training of our manpower. The ability to fully integrate with our sub-systems was crucial. Security was obviously a top priority for us at SAMHS and we had a requirement for over 500 cameras and associated networks. We also needed to address our energy saving require-ments in the most cost-effective and environmentally friendly manner. The benefit of having HBS involved in the on-going maintenance and updating of the EBI system also gives us peace of mind.”

Vodacom has announced that it is fitting its Century City in Cape Town office with the largest array of solar panels on a single building in continental Africa and that it has appointed In-Toto Solutions (Pty) Ltd as the EPC contractor for the project. Nearly 2000 mono crystalline solar panels will cover the 3 600m² roof of the building.

The solar array will be completed in August and is expected to provide up to 75% of all power required by the building during peak production. The power produced will feed into the two main distribution boards. A display panel, installed in the reception area of the building, will display instantaneous power yield, energy yield and carbon emission savings.

The high profile Eastgate 20 building that has been redeveloped on the corner of Grayston Drive and Katherine Street in Sandton is an excellent example of the perfect balance being achieved between design, sustainability and performance.

It was partially Ecosure’s extremely low VOC (Volatile Organic Compound) levels that made it the ideal product for the interior painting of the build-ing, especially in its office and public areas. This range of water-based paints offers “best in class” coverage and application characteristics, providing a superb balance of sustainability and performance.

According to Thulani Sibande of Para-gon Architects, Dulux Trade’s Ecosure complied ideally with its green rat-ing requirements. “We specified the product that we needed and Ecosure worked very well for the project. We requested data sheets to comply with the green star rating requirements and these were very efficiently supplied to us,” says Thulani, adding that the entire development had to meet strict standards to adhere to and qualify for a level four green star rating.

“It was very important for the paint to meet the VOC levels we specified and for it to provide a professional finish.”

Wall welfareThe same strict environmental criteria was applied to lighting, heating, water, sunlight and other aspects that needed to be considered in the overall green rating process.

Importantly, Ecosure has been spe-cifically formulated to have a demon-strably lower environmental impact than standard Dulux Trade products, while maintaining the highest possible standards of quality and performance.

With more and more developers, archi-tects and contractors placing a strong emphasis on sustainability throughout new and redeveloped buildings, paint manufacturers such as Dulux and AkzoNobel are placing a strong focus on ensuring that using eco-paints does not mean any sacrifice on performance levels.

Saint-Gobain Gyproc has launched SoundBloc, a light weight construction system that limits the transmission of sounds as loud as 81dB. This system is ideal for use in healthcare and educa-tion developments where blocking the transmission of noise has a positive impact on the environment.

The SoundBloc system incorporates a specially manufactured lightweight steel stud and track structure, and glasswool insulation made from up to 80% recycled glass. It has a light blue colour paper finish for ease of identification on site.

The locally produced SoundBloc system underwent international fire and acoustic tests, meeting European standards, conforming to the BS EN 140-3:1995 test procedure.

Research has shown that optimal noise level that is conducive to healing in a hospital is just 30dB, equivalent to the sound of dried leaves rustling in the breeze.

In a study conducted by European In-dustry leader, Echofon, it was revealed that when children are learning in an environment with an ambient noise of 55dB they make mistakes at a rate of 4.3%. When the ambient noise is 60dB (the sound level of normal street traffic) the mistake rate is as high as 15%.

The Millennia Park office building has achieved a 5 Star Green Star SA Office v1 ‘Design’ certification from the Green Building Council of South Africa (GBCSA) – the first time that a refurbished building in South Africa has received this accolade.

Situated in the historical heart of Stel-lenbosch, the 29-year old building was considered an architectural time-piece in the town, and as such it was decided to refurbish the building rather than demolish it. More than 96% of the original structure was retained.

Millennia Park is the new head office for investment giant Remgro, which sought a new location for its increased

staff complement following a merge with Venfin, in 2009. The building now houses about 120 staff members, who moved into the building in early May, after the refurbishment was completed in April.

Achieving a Green Star SA rating on a refurbished building, poses an entirely different set of challenges when com-pared with the construction of a new building, which can be designed green from the start.

Despite these challenges, and com-mitted to environmentally sensitive development, Remgro instructed TV3 Architects, Project Management firm Bornman and Associates, and Quantity

Surveyor De Leeuw Stellenbosch, to compile a professional team capable of completing this green refurbishment on time and within budget. Additional consultants such as landscape archi-tects, freshwater ecologists, environ-mental consultants, geo-hydrological consultants, acoustic consultants and an independent commissioning agent were brought on board.

“With a refurbishment project, you have to take what you have and work with it, you can’t change the orientation of the building for example. This forces you to be more creative, and overcome inherent challenges,” explains Bornman & Associates director, Chris Bornman.

Andrew Wood of GLH Architects, in consultation with representatives of Mapei South Africa, recently chose products to complete the revamp of a parking garage for a corporate client in Randburg.

“Preparing the 5 700m² area was quite a challenge. Over the years a number of different coatings, including epoxies, had been applied and these proved to be difficult to remove which was a prime motive for the choice of specialist applicator, Indufloor,” explains Peter McArdle, specification consultant flooring, Mapei South Africa.

Indufloor indicated competitively-priced Mapefloor I 300 SL for the application as it fulfilled the technical specification. This strong, durable, multi-purpose, two-component epoxy offers high abrasion resistance with aesthetic appeal for various industrial applications. The treatment is ideal for use in self-levelling projects of up to 4mm, and offers a seamless floor surface. “This quality, in conjunction with the product’s non-slip surface, made it the perfect flooring solution for this area,” says Peter.

The need for safe, comfortable and convenient lifestyles by people enjoying their golden years is supporting a level of demand in an otherwise sluggish residential property market. This is the view of Gerhard Zeelie, Standard Bank Property Finance head of residential development finance, who tracks the retirement development market and sees it as a growing niche. Standard Bank has provided about R717 mil-lion in funding for retirement village developments over the past 3 years.

Gerhard says that in real terms residen-tial property prices are thus decreasing. “This presents a challenge for a lot of developers and financiers to identify

niche markets that are growing at above average rates compared with the rest of the property market.”

One such niche is the retirement market and specifically the more affordable retirement market. The Central Develop-ment Group has been very successful in capturing this market and Standard Bank has provided financing on a number of these projects.

The partnership has successfully brought to market four developments in Gauteng since August 2009, with three having been marketed over the past year. The developments are the Tweeriviere and Wilgers developments

in Pretoria, Douglasdale in Fourways and Village Walk in Benoni.

Gerhard also points out that develop-ers need to ensure that the required common infrastructure like frail care, dining room and recreational hall are built during the first phase and delivered before any purchasers take occupation. “Initial purchasers can, therefore, rest assured that they will not find themselves living in a development where promised infrastructure is not delivered. For the financier and the developer, getting this right and in place from the beginning greatly enhances the marketability of the developments,” he concludes.Standard Bank Group, Ross Linstrom, Tel: (011) 636-3629, Email: [email protected]

Assa Abloy Entrance Systems SA recently installed four Unislide single sliders in the baby rooms and restrooms in Nicol Way shopping centre in Bryanston, north of Johannesburg.

“Due to the fact that this particular installation involves vulnerable mothers and babies, we had to install additional safety sensors inside the cubicle.” MD Andre Aiton explains, “The system’s function is designed for safe and easy entry and exit via a convenient ‘AK-Elbow switch’ placed on either side of the entrance. A control system func-tions as soon as the customer is inside; various sensors inside the cubicle are activated to cut off the entry switch on the outside with a red LED indicating that the cubicle is now occupied. No-one can enter the cubicle at this time, offering optimum safety and peace of mind to the occupants.

“To exit the cubicle, the exit switch is pressed and the LED on the entry switch will automatically turn green, indicating that the cubicle is now unoccupied.”

Andre adds that the system has been so successful that it is in use in many of the new and larger shopping malls.

“Maintenance plays a crucial role as regular upkeep improves the lifespan of doors and prevents costly call-outs and as well as the embarrassment of doors that are not operating. Our professional technical teams are on

EPS (Expanded Polystyrene) is a lightweight cellular material derived from petroleum and natural gas by-products. EPS sheets and boards are used extensively for thermal and sound insulation in

walls, roofs, and on floors. Loose beads are used as aggregate in lightweight concrete, plasters and renderings. Other uses include under-floor heating systems, drainage boards, permanent formwork, foundation and prefabricated wall systems.

Low carbon footprint As thermal insulation, EPS saves up to 400 times the energy originally required to manufacture the base product.

No CFC’sEPS consists of organic materials, making it one of the most ecologically harmless products available.

Conserves energyThe excellent thermal insulation performance of EPS makes it an efficient and effective solution.

Easily DisposableCorrectly incinerated, 100kg of EPS leaves just 0,01kg ash and emissions are non-toxic.

Life Cycle Assessment (LCA)The Life Cycle Assessment from manufacture to disposal supports the

environmental impact benefits of EPS for sustainable building and development.

RecyclableEPS is recycled into a variety of products such as picture frames,

curtain rods, skirting and decking. It can also be broken down, mixed with refuse and burnt as fuel, or provide aeration which

assists in the breakdown of organic matter in landfills.
