Finishes, appearance-enhancing additions and accessories for buildings are the theme for edition 11 of TO BUILD.

Why live or work in a plain Jane building when we live in a time of an amazing selection of different decorative and functional accessories for buildings? So given our difficult economic times, falling Rand and rising fuel costs, at least you need not to live or work in a boring space.

To help liven up your space, a quick visit to your local home store can do wonders. Some items will be purely design orientated or simple, whereas others are extremely functional and high tech like specialised coatings that offer superior performance and long life.

It it is heartening to see the efforts being made by so many companies and institutions towards sustainable and green building. Once again, we feature some of these projects in this book.

2014 is the big year of design in South Africa, with Cape Town fulfilling its role as the Design Capital of the World, 2014. At TO BUILD, we look forward to featuring your designs. Do send them in for publication!

Designed for half a century or moreMarianne and Beat Heller took on quite a project when they bought the Hotel Eiger in the Swiss spa resort of Grindelwald in 1962. By 1966, they had already

The 1960s weren’t just about major advancements in music and space travel – a new wind was blowing in residential construction too. Spacious floor plans, central heating, large windows and fitted kitchens were all the rage. And although bathrooms were still fairly small, change was in the air here too. The Geberit concealed cistern found its way into bathrooms in 1964 and provided a valuable space-saving solution. The Hotel Eiger in the Swiss spa resort of Grindelwald was among those who got on board with the first Geberit concealed cisterns, setting a trend in bathroom design.

The bathroom revolution

A faithful friend – A 1966 Geberit concealed cistern was revealed behind the wall during the complete refurbishment of individual bathrooms at the Hotel Eiger. It had been reliably performing its duty for 48 years since it was first installed.

replaced the part of the hotel on Dorfstrasse with a new building. Even when viewed from a distance, this was a building that signalled Hotel Eiger’s status as the most modern establishment in the whole village.

Testing the ties that bind: Even back then, Geberit tested the reliability of all of its products as part of its quality assurance procedures. As the Hotel Eiger has shown, the cisterns can last for 50 years without any trouble at all.

But it wasn’t just the facade that embodied the architectural zeitgeist of the 1960s – the interior fittings were also state-of-the-art features. For example, all the new bathrooms contained a wall-hung water closet (WC) with a Geberit concealed cistern – technology which, at this point, had not yet become widespread. In fact, Geberit had begun series production of this cistern, which was completely concealed behind the wall, only two years earlier. It presented a challenge to some users, as most of the hotel guests had never seen this kind of toilet flush on the wall before; so when guests first checked in, hotel staff made sure to explain that the little button on the wall was for flushing the toilet.

A love of innovation and a spirit of confidence“My parents were big fans of innovation,” says Daniel Heller, who took over the management of the hotel twelve years ago. “They were among the first in Grindelwald to own a computer. It took up half the room!” It is progressive building owners like the Hellers and sanitary companies like Ruoff AG that we have to thank for the fact that the concealed cistern and, hence, prewall technology were able to flourish.

For Ruoff AG, a long-established sanitary company based in Grindelwald, it was the first time that they had been given the chance to install this type of cistern. As the building owners insisted on having sound insulation and modern fittings, it was decided that all of the sanitary technology was to be installed behind robust brick prewalls. And the Geberit concealed cisterns, which had only really been on the market for a year at that point, came along at just the right time.

The tradesmen who installed the systems had to demonstrate a certain level of proficiency because, at that time, Geberit was not able to offer any special installation aids beyond a few metal brackets.

An icon of reliabilityGeberit concealed cisterns have been in use for 50 years. For over 30 years, they have been manufactured in a single operation using a blow-casting process, which means that they have no seams. Each individual cistern is tested for 100% tightness at a testing station.

As the concealed cisterns have a very long service life, Geberit guarantees availability of spare parts for at least 25 years for all function-maintaining components. Even today, retrofit kits for a stop-and-go flush are still available for the first generation of Geberit concealed cisterns.

The Geberit Group is the European market leader in sanitary technology with global presence, and has sales offices in 41 countries. The Geberit Group generated a sales volume of CHF 2.2 billion in 2012 and employs 6 100 people.

Production today: Today, Geberit manufactures concealed cisterns using a blow-casting process. They are produced in a single operation, which ensures that the products will work reliably for decades.

Geberit Southern AfricaW www.geberit.co.zaT +27 11 444 5070E [email protected]

Once installed, however, the cisterns lived up to expectations; they remained leak-proof and worked flawlessly. A large number of the first generation of concealed cisterns are still in daily use today.

Up until recently, this was the case at the Hotel Eiger in Grindelwald, but not any more – the end of 2013 saw a complete refurbishment of the bedrooms and bathrooms, in the course of which the nearly 50-year-old cisterns were removed and replaced with new ones. “Throughout the entire planning phase, we had no idea what would be waiting for us behind the wall,” says Thomas Ruoff, the fourth generation of his family to run Ruoff AG. “So we were a bit surprised when we found all of the pipes and cisterns in perfect working order. These installations would definitely have carried on working for many years to come.”

Vital statistics of Geberit concealed cisterns

• More than 60 million have been installed and tested over a long period of time.

• There is a right model for every construction situation.

• Guaranteed spare parts availability for 25 years.

• Modern flush technology ensures excellent water efficiency.

• There is a large selection of attractive Geberit actuator plates.

Quite a sight: Once the building rubble had been removed, the cistern shone almost as brightly as it did when it was new. “These installations would definitely have carried on working for many years to come,” says plumber Thomas Ruoff.

Brighter still: The bathrooms in the Hotel Eiger are now shining brighter than ever before. They have been fitted with a Geberit Sigma concealed cistern and a Geberit Sigma01 actuator plate.

Reliable and completely concealed behind the wall: When the wall was opened up, the Geberit concealed cistern was revealed to be in excellent shape.

The 3 000m² premises occupy the top three levels of the Atlantic Centre, a new office development on Cape Town’s eastern foreshore. There is a magnificent double-volume interior, partly broken by a mezzanine level, spilling one floor below. Great views occupy the generous two-story windows of the ninth floor and on the other levels where they showcase the harbour, Woodstock and Devil’s Peak. Prior to occupation, it had been an empty shell and this served as a wonderful blank canvass for designers.

building, the “wow” factor is unavoidable. To Build’s editor was welcomed and allowed the use of a very unusual workspace located on top of a converted freight container from which to plan the shoot.

The designers, Inhouse Brand Architects were approached to create the new Cape Town offices of top advertising agency, 99c. The goal was to enhance an already spectacular site. Another goal was to create a fully functioning environment to suit the client’s daily business needs, in addition to reflecting the creative nature of the agency and its employees.

Extensive planningPrior to design, an extensive study into the company’s daily activities was undertaken. Steered by Inhouse Creative Director, Aidan Hart, and Senior Designer, Moiisha Visagie, the study looked at the employees’ possible needs from the perspective of activity-based work principles. This enabled the client to understand what the most effective space-planning layout would be.

Inhouse allowed for all types of interaction and both high-focus and high-communication zones. High-focus zones were defined as individual desks where concentration could take place, hence interaction with others would be minimised. High-communication zones were defined as spaces that would facilitate teamwork, interaction and collaboration.

In a more traditional office environment, a meeting room or cafeteria would constitute a high-communication zone. At these offices, however, the need to meet informally is catered for by various, so-called “campsites”, which are collaborative, shared spaces. According to Hart, “The latest office trends suggest that collaboration happens at the water-cooler dispenser and does not necessarily demand office space or a meeting room that underutilised most times.”

Taking this into consideration and also that the office is split over three separate levels it was crucial that the design team make optimal use of the available area while encouraging collaboration and connectivity. Hart explains that stimulating connectivity is paramount, since one of the problems with corporate office space is level-by-level stagnation where departments are divided into operational silos that foster corporate disunity. “As a design company we feel that part of our strength lies in enhancing cross-floor communications and hopefully improving inter-personal connectivity. In this instance, the client was progressive, and wanted to use the opportunity presented to improve the work environment,” he says.

How it was done…According to Andrew Brand, 99c Managing Director, it was “important that our new office space not only expresses our creativity but also encourages and enhances it. As an agency, 99c creates the positive change that our clients require to achieve brand success, and we also embrace this ethos ourselves in our daily lives and work environment.”

To achieve greater connectivity for the 99c team, a hole was made in the existing concrete slab between the eighth and ninth floors (incorporating the mezzanine level) to insert a new stairwell. The boardroom was intentionally placed on the eighth floor, away from the ninth floor reception and lounge areas, to promote the circulation of staff between the floors.

A new stadium structure was installed to replace the existing staircase between the ninth floor and the mezzanine level. The structure houses and conceals the galley that services both the café and bar area on the ninth floor.In addition to providing access to the mezzanine, the stadium steps allow for an informal seating for an arena that can be gathering spot for the entire company. A large discretely hidden motorised projection screen turns the arena into a big-screen cinema to review work, or watch advertisements or video.

A series of semi-private pods and high-energy meeting spaces was created throughout the space to allow employees to interact freely without tying up formal or valuable space such as boardrooms which have to be booked. These areas reveal a select palette that incorporates the corporate colours. Burnt orange, blue, black and lime yellow are used to brighten detailing and feature walls. Colourful elements include oversized dome pendants that illuminate the generous space. The unstained “box wood” finish of the massive staircase leaves a lasting impression.

Building biologyTaking advantage of this double-volume span, six large trees were incorporated around which café tables were structurally laid out. The indoor landscaped garden was positioned on decking and raised slightly to demarcate a communal, informal zone.

In addition to the trees, numerous living walls were placed throughout the space to link it to the natural environment. The green factor enhances the interior for the user and softens the office environment.

Sustainable materials such as pine and plywood were used extensively throughout. Textured-looking Oriented Strand Board (OSB), which has a patterned yet smooth finish, was used extensively for tactile impact and warmth. Moreover, it achieves a stylish effect for a modest cost.

Out of the box thinkingA recycled shipping container was converted into an innovative waiting room near the reception. It boasts a working area on the top and with side panels removed it is both functional and very unusual. It is in sync with the theme of sustainability – re-use, recycle and reduce – illustrating respect for the sustainable building movement. It is also an indication of to the creative nature of the client’s skills. The agency’s out the box thinking is both ironically and graphically demonstrated. It echoes 99c’s purpose, existing to produce creative solutions that are shipped around the globe, just like a shipping container.

With the office’s panoramic views of container ships in the harbour, the waiting room serves as a subtle reminder to 99c employees of the importance of client service and delivery.

The editor thanks 99c agency for their hospitality in allowing access to their offices during working hours for the photo shoot.

Inhouse’s designers have delivered a world-class office solution, embracing elements of activity-based work thought-systems, tailored into a standout, contemporary environment. Inhouse Brand Architects are known for their breakthrough work at Ogilvy Cape Town, and has also completed Black River Park FC and Metropolitan Republic Johannesburg, on the advertising front. The company has also completed a string of singular, award-winning projects for restaurants such as The Test Kitchen and Carne SA, in addition to corporate offices for Union Swiss and several others. In 2013 the company received eight local and international awards and accolades, including a Silver Cannes Lion, deservedly a contender for the forefront of the SA interior design industry.

OSRAM ran an exciting Halogen Eco SMS competition at participating retail stores from 18 May – 18 August 2013 whereby shoppers had to spot the difference between the old incandescent lamp, and the new halogen eco lamp on a display in-store. The intention was to emphasise that you can save energy without having to change what your “lamp” looks like by going with OSRAM’s new halogen eco technology.

The lucky winners were Mr and Mrs Breytenbach who received their grand prize – a boat cruise for two to the exotic Portuguese Islands – from OSRAM at the Makro, Alberton store late last year. There were also five runner-up winners of a R 5 000 shopping voucher.

The OSRAM halogen eco lamp has the same look and feel as the old incandescent household lamp, but you can save up to 30% energy, and it’s dimmable.

A ban on incandescent lamps is now enforced in Europe and there is talk that South Africa will follow

After a challenging negotiation battle last year between employers (represented by South African Federation of Civil Engineering Contractors – SAFCEC) and unions (represented by Building Construction and Allied Workers Union – BCAWU – and National Union of Mine Workers – NUM) in the civil engineering industry, various agreements are now finalised and were taken to the Minister of Labour to be promulgated. These agreements include:• Wage and Task Grade Agreement

• CIRBF Agreement (Construction Industry Retirement Benefit Fund)

• Registration and Administration Expenses Agreement

• Conditions of Employment AgreementThe Bargaining Council of the Civil Engineering

Industry (BCCEI) says it has revolutionised the stock standard main industry agreement by unbundling it into various separate agreements. Thus, it narrows down disputes to a specific agreement.

The BCCEI’s second AGM is set to take place in March 2014. Nick Faasen, General Secretary of the BCCEI says that the establishment of the Council will provide all parties with an opportunity to proactively address some of the industry challenges in a positive manner. The organisation will provide an institutionalised platform for bargaining of collective agreements suited to the industry.

As from 1 March 2014 all industry disputes will be referred to the BCCEI, however hearings will continue to take place at the Commission for Conciliation, Mediation and Arbitration (CCMA). The CCMA will provide assistance with the establishment of a dispute settlement department for the Civil Engineering Industry. All employers within the Civil Engineering

Industry are urged to register with the BCCEI and commence discussion regarding administration and dispute levy deductions with their employees. The date from which deductions will have to be made will be communicated to the industry shortly. The same will apply to employers and employees who are currently not contributing to a retirement fund. CIDB1-3 graded employers (small businesses) are excluded from BCCEI registration.

The Real People Group, positioned as a responsible lender that offers purpose specific lending is closing its general purpose branch-based lending business to focus on purpose-specific lending and debt rehabilitation. This move is in line with its vision of ‘sustainably improving lives’.

Neil Grobbelaar, Group Chief Executive Officer of the Real People Group believes that the current negative sentiment towards the lending sector serves to validate the Group’s plans to focus on sustainability.

For Grobbelaar the economic outlook for consumer lending is very challenging, and he believes the general consensus within the lending sector is that the boom has come to an end, with only a few players being able to prosper in this sector in the future.

“It is from these realities that the Group’s vision was born and we have learnt that we have to be a lot more cautious about how and who we lend money to. Through coining the phrase ‘responsible finance,’ our lending is purely purpose driven which means the end result must create value in people’s lives. Here the role of rehabilitative finance and assisting people to overcome their debt burden is a critical component of

the so-called responsible finance offering,” he says.Over the last two years the Real People Group

has been gradually, but deliberately, increasing its proportional exposure to purpose-specific housing and business finance, and reducing its proportional exposure to general-purpose credit. Grobbelaar says that this will also allow the Group to focus more resources in the development of its businesses in Eastern Africa, specifically focussing on further growth in its SME finance offering and the launching of its home improvement-finance offering in that region.

“The home-improvement finance product line is a significant contributor to the business, currently accounting for 80 percent of monthly new business intake in South Africa. This product is delivered through 650 points-of-sale countrywide and the Group enjoys strong relationships with, amongst others, the Build-It Group, the Essential Group, DIY Depot, Timber City and Penny Pinchers. In addition in 2013 the Group also signed the Massbuild Group, which consists of Builders Warehouse, Builders Express and Builders Trade Depot,” he says.

Designing with legacy in mindGlobally, much more attention is now being paid to maximising the sustainable legacy of these structures, bearing in mind the huge investment and upkeep they require, rather than short-term (event driven) needs. There are various key issues to consider, as listed below, in addition to meeting time and budget constraints.

Successful world-leading stadium design means thinking beyond the obvious and certainly beyond the main prestige event. While it has to meet the client’s brief to accommodate a global event, a true legacy design involves maximising the stadium’s afterlife usage. A good example is the Perth Arena, which became the centrepiece for the redevelopment of the Northern part of the central business district. It features the Aurecon designed high-performing, fully retractable roof and

Creating iconic architecture Although stadiums are often status symbols for a city, region or nation, the drivers vary on a case-by-case basis. For example, while the Beijing Olympics projects were strongly influenced by iconography and the main event, the Sydney and London Olympics sports facilities were more driven by legacy planning.

Any building that accommodates tens of thousands of people is inevitably a large structure and a dominant feature on the landscape. This presents an opportunity for iconic architecture expressing how a region and the nation want to project themselves.

Aurecon believes stadiums should become impressive status symbols – not just in their

architecture, but also in their engagement with the fans and the public – and endure.

Summiting the rooftop challenge A stadium’s roof is a demanding structure to design and build. Collaboration between architectural expression and engineering requirements of strength, serviceability, and durability must exist.

The structural engineer in particular needs to take a very proactive yet collaborative approach to achieve the overall architectural vision within budget and in a buildable form.

There is no absolute right or wrong roof form. What is architecturally stunning with the right functional geometry is one thing and what works efficiently can be another. Sometimes great design outcomes are often achieved when key aspects are carefully considered in an integrated fashion.

Modern stadium roofs are designed in an excitingly diverse array of structural forms: ranging from the rather conventional cantilevered and long-span systems to the more exotic shells, cable nets, and ‘tensegrity’ roofs.

Appropriate construction materials and correct application are particularly important. Steel is a good option for long-span structures because of high strength-to-weight ratio, ease of use and cost

effectiveness. Lightweight, durable cladding materials have resulted in the increasing use of high-tech tensile membrane systems.

To incorporate a fixed or a retractable roof requires the holistic evaluation of the value in weather protection versus turf health, and the impact of shadow effects on spectator viewing and TV broadcast quality – all these have implications on cost, risk, functionality and potential return on investment for the project.

Elaborate roof designs need careful assessment of wind loads on the structure, while the overall design has to ensure that spectators are comfortably shielded from wind.

Using modelling and simulation, Aurecon can test the building and de-risk it before it is built, without compromising its technical integrity.

The natural turf trend Healthy, natural grass means designing for lengthy exposure to sunlight. This creates a roof opening optimisation conflict. Too small an opening means high cost turf repairs and maintenance, while too small a roof means wet spectators during rainy periods. Two case studies are appropriate.

At Forsyth Barr stadium in Dunedin, New Zealand, membranes of ethylene tetrafluoroethylene (ETFE), were used to create air-inflated pillows as the

roof cladding material in this, the world’s first fully enclosed grassed stadium. Aurecon’s award-winning design relied on advanced modelling and simulation techniques to verify that the adequate air ventilation and sunlight exposure can be maintained for grass health within the fully covered stadium.

In Melbourne, the 55 000-seat multi-purpose Etihad Stadium maintains its natural turf in a healthy condition via the stadium’s fully retractable roof that takes only eight minutes to close. Localised grow lights are utilised particularly on the higher wear areas over the pitch. The combined strategy is delivering high quality grass despite heavy usage.

Ensuring multi-use functionalityAs adaptable, high performing buildings offering multi-use functionality, the modern trend for stadiums is for physical flexibility – designed to shrink capacity using modular and demountable concepts.

Upper tiers and even upper structures can be removable, so building services also need to be modular and demountable. At the Perth Arena in Australia, the simple solution was to have curtains that can close off the back tiers seating to create a cosier ambience during smaller events.

The vibrations induced by crowds’ synchronised motions need to be carefully studied in the design of the seating tiers.

High-tech thinkingIn-game augmented reality content delivered direct to spectators’ smart phone applications, enhanced pre- and post-match family orientated entertainment produced by in-house production teams, and unique rewards for attending matches such as special food and beverage incentives are designed to draw fans away from their living rooms and into the stadium. Trends in leading stadiums are high-tech with WiFi for smart phones. Soon the use of multiple cameras and more sophisticated broadcasting technology will enable fans to select and track the activities of individual players via smart phones.

Advances in computer technology modelling techniques such as Building Information Modelling (BIM), Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) are becoming ‘business-as-usual’, extending the boundaries of structural form and architectural expression ever more rapidly. At the same time they are ensuring safety and promoting time and cost savings.

A strong modelling capacity, such as that of Aurecon, is boosting sustainability. This will be reflected in stadiums consuming less area and tonnage of material, onsite power generation with photovoltaic arrays on the roof, grey water reuse, thermal storage, and a stronger focus on carbon neutrality.

Creating fan comfortThe current stadium design buzzword is ‘Fan First’. Professionals play a large part in delivering stadium projects that encourage fans to leave their homes in favour of enjoying the event at the stadium. Assuring comfort is key.

Concepts include the installation of cooling pipes in the concourse slabs and displacement air-conditioning delivered via plenums under seating platforms throughout the stadium – as a sustainable way of achieving a comfortable environment.

Premium seats should be laid out by the need to facilitate delivery of food and refreshments, meaning fans do not miss any action by having to leave their seats for refreshments.

Smart phone applications, optimal temperature control, food and beverage delivery, in addition to a spectacular live entertainment makes stadiums appealing – the experience cannot be replicated at home.

Adendorff Architects & Interiors (AA&I) is made up of a group of young and dynamic architects, senior technologists and interior designers.

Principal architect Gillian Adendorff founded the practice in Port Elizabeth in 1992. She qualified in Architecture at the University of Port Elizabeth (now NMMU) under the auspices of the late Professor Danie Theron and currently she continues her academic career with the submission of a PhD on the topic “Possible Futures for the African Built Environment Toward 2050” at the Nelson Mandela Metropolitan University.

Adendorff Architects & Interior’s offices are situated in a green suburb of Port Elizabeth, where an abundance of trees and birdlife ensures a stimulating and creative backdrop to their vibrant practice. The office is made up of young, energetic professionals, who each bring something special in terms of their work as well as their personalities. The ability to work well together and communicate strong ideas amongst

each other, and realise those ideas, is a key factor to the success of each project as well as the practice as a whole.

Strong people peopleAnother great part of their success, Adendorff believes, lies in the ability to view themselves not as ‘problem-solvers’ but rather as being able to recognise opportunities to create unique environments which enrich the lives of the end users though space and volume. As a result, their approach to design, from a macro to a micro scale, is constantly evolving in order to respond to a rapidly changing and demanding industry.

“We have strong working relationships with our clients, both new and long-term, who are confident that we can work with them and guide them in creating unique, practical solutions which are considerate of their needs, but also seek to be something more than

just ‘ticking the boxes’ on their brief. We are convicted to strive for an overall vision, which encapsulates the spirit of the project as a whole. As a result we address a variety of exciting challenges, always bearing in mind what the greater design philosophy of the practice is.”

One of these great challenges that they constantly face, which every other designer faces in the light of today’s economy, is that of tight budgets. “We often feel that these are restrictive in relation to the brief and the client’s expectations; however, this forces one to think more laterally and often has some pleasing results,” Adendorff tells us. Indeed, their involvement in the recent VW recreational facility for staff and families is an outstanding testament to working to tight budgets for great results.

Detail peopleThese great results are a product of thinking consciously about detail design at all stages of the design development as well as the implementation of the project on site. The practice is always encouraging its designers to think consciously about how they are responding to the environment, and how they

are promoting the longevity of the building; in other words, going beyond comfort zones and pushing the boundaries.

AA&I is passionate about clients and its work, which is varied and covers a broad base. This includes retail & commercial, sports & recreation, restoration & refurbishments, hospitality and leisure, industrial, urban upgrades, residential aged care development and housing. The practice has worked on projects throughout South Africa and also abroad in culturally diverse countries such as USA, Greece and Pakistan. They are currently involved with a hospitality project in the Mediterranean.

Greg Straw, Managing Director of Earth Architectural Landscapes Pty Ltd, is best known in South Africa as the landscape architect of the Nelson Mandela Memorial Gardens in Qunu in the Eastern Cape, Mandela’s ancestral homeland and final resting place. The common thread through his impressive portfolio for projects and clients is ‘oneness’ with the environment.

As a landscape designer, qualified from the Natal Technikon, Straw has been involved in a variety of exciting projects showcasing his versatility in this field. This includes: setting up an endemic plants nursery on the Magaruque Private Island in Mozambique; eradicating an entire island of all invasive plant species; and doing a general clean-up of the beach and bush areas on Santa Carolina Island, Vilanculos, Mozambique. Straw’s strength lies in knowing the ins and outs of the sector, and understands that above all, project longevity and sustainability is reliant on the vegetation’s suitability and harmony to its surrounds.

Straw has served the residential, commercial, industrial and recreational markets since 1990. He provides bespoke, innovative landscape architecture solutions which offers professional service and efficient maintenance schemes. In addition, he is a committed

Leading landscape designer: In harmony with nature

environmentalist who firmly believes in habitat restoration.

When creating a garden in the concrete jungle in Johannesburg or a botanical garden in Israel, horticulture, hardscaping, architectural landscaping and irrigation engineering are used to rehabilitate, create and maintain.

Straw’s vision of the completed garden considers the endemic plants, the drainage constraints, the climate and what is visually appealing to the eye. Unity and harmony are created when the architectural style of the building is considered together with the landscape layout and design. Different landscaping elements should be combined with appropriate hardscaping to consolidate everything. He has succeeded in accomplishing exactly that with the Sandhurst Towers Rooftop Gardens in Sandton where the biggest concern was the weight of materials and adequate drainage. To overcome this hurdle the decision was taken to utilise lightweight materials for the outdoor living area at the design stage of the project. An outdoor shower, day bed, swimming pool, koi pond, plants and a barbeque were some of the garden elements to be included. Straw then used the landscape elements to unify all these points of interest.

The value chainTo add some colour and life to spaces, be it at home or the workplace, a variety of plant products are available at the following nurseries:

• The Earth Outdoor Living Nursery in Fourways is a delight for gardeners and offers an extensive range of garden plants, flowers, shrubs, trees, other plant life and garden décor.

• The Growers Wholesale Nursery is a production and experimentation nursery that produces between 400 to 2 800 plants a day.

• The Eastern Cape Aloe and Succulent Nursery is a water wise indigenous production nursery situated in Qunu on the Mandela Farm.

• The Vilanculos Tropical Nursery in Mozambique produces a wide variety of tropical plants – both indigenous and exotic – for the local market, hotels and beach lodges.

• The Pemba Nursery produces plants and vegetables for the local community, as well as plants for Pemba Beach Hotel.

A place to unwindStraw’s Fourways Farmers Market was established as a place for families to picnic, away from the stress

of the city. This speaks to his fun side, which shines through regardless of a hectic schedule and pressing time constraints. “If you cannot grow it, bake it or make it, you cannot get a stand here. Our exhibitors and our visitors love it. You can buy all the food for your picnic right here and sit and relax. The children have a safe playground while parents can just enjoy,” says Straw.

What’s on the horizon? Greg Straw has a coffee table book on the Nelson Mandela Memorial Gardens in the pipeline. He is currently working on creating a Greg Straw branded range of Fourways Farmers’ Market products to be sold at the Fourways Market. Further to this he intends to continue to inspire the nation with symbolic gardens, using plants endemic to the area and combining all the elements of great design with each completed masterpiece.

The architect is faced with huge and varied challenges when designing buildings. In addition to overall design, the mechanical or technical efficiency of a building has to meet many important environmental requirements including the relationship between temperature and humidity. The air we breathe is increasingly full of harmful substances, more so indoors. In addition to their air-purifying and aesthetic advantages, indoor plants go through transpiration which produces moisture. This is presented in the form of moisture on the underside of leaves. This natural ability to produce moisture, and the contribution this can make to maintaining optimum humidity levels offers designers an effective and practical solution.

Academics and corporates agreeProfessor Vanessa I. Lohr and Caroline H. Pearson-Mims of Washington State University conducted studies in a computer laboratory and a small office at Washington State. The study showed that where indoor plants were present, there was a significant reduction in the levels of particulate matter, with the levels of dust being reduced by at least 20%. This is backed up by the studies of one of the most highly regarded corporations in the world, BMW. Facing workplace health issues, the Munich BMW plant, undertook tests on the benefits of including indoor plants in the workplace. After gathering data from areas with and those without indoor plants, the statistics showed that 93% of the employees experienced an increase in motivation and feelings of improved health. Beate Klug, the health and safety officer for BMW, said that staff experienced a reduction in noise levels and preferred to work with the natural effect of indoor plants. Where plants were present, improved humidity levels led to improved comfort levels.

The Interior Plantscaper Association of South Africa (IPSA) argues the case for incorporating plant life during the design phase.

Smart HVAC design incorporates foliage

During their study, the Washington State University research team determined that when plants were absent from a room, relative humidity was very low and often below the recommended range of between 30 and 60%, the levels recommended for human health and comfort. With plants present, the relative humidity rose significantly but not excessively. In one case where it was found that relative humidity without the presence of plants averaged 25%, whereas with plants it averaged 30%.

The role of leavesThermostatic control of temperature is the most commonly used method of regulating indoor temperatures. As a stand-alone measurement, this is not a true reflection of comfort levels – to achieve optimum thermal comfort, temperature has to be considered together with humidity, clothing, air velocity and other inter-dependent factors.

Melanie Ewing, owner of Chapters Interiors, shares some valuable advice…

ABC of décor

Are you ready to decorate the home? There are three simple things to take into consideration when making changes to your interior decorating – style, design principles and space planning.

StyleThere are two key things to remember when deciding on style – your own style and your home’s architectural style. The two should complement one another, achieving harmony rather than discord. Without being able to identify the two, decorating can end up being a frustrating and costly exercise.

Developing and evolving your own personal style is a lifelong process. Tastes change and develop over time as you get older, and you develop confidence. You might have lived in another country which resulted

in a change in your style. Socio-economic trends or life-stages change, or you can be influenced by others. Being exposed to and aware of a variety of designs over a long period of time will help to identify your personal preferences. You may like the clean, harder lines of a modern structures and furniture. Or alternatively, you may like the indulgence of Victorian drapery and fabrics. Style is personal.

But, how do you develop your own personal style? It is something that grows and develops over time – you just need to be aware of your surroundings and choices. A tip is to get into the habit of observing design details everywhere – in shops, magazines, homes and gardens. You’ll find that you are constantly drawn to the same type of design or décor again and again.

Design PrinciplesConsider a recipe you choose when planning a dinner party. If chosen well and prepared correctly the meal will be delicious. However, sometimes you need to adjust the recipe, improving the taste and adding your own particular stamp (that extra pinch of curry powder, a hint of something exotic etc.) to achieve the desired result. Similarly, design principles are your recipe for success when decorating.

The most important design principles to be aware of are:• Focal Point – Every room should have one. It’s an

area where the eye rests that is visually pleasing or interesting.

• Proportion – All furniture should be in proportion to the size of the room. For example, a small lounge with an over-sized leather couch in a dark colour immediately reduces the size of the room.

• Scale – A simple trick that always works is to have a large, medium and small copy of exactly the same thing in the room, almost like a Russian nesting doll.

• Space – Be sensitive to the space. There is no need to fill every empty gap. The amount of space between items can change the atmosphere of a room.

• Rhythm – Repetition of a colour, theme, object, or texture creates rhythm. It is the secret ingredient that unifies the room and creates harmony.

• Line – Think of the way pictures are hung. If the line is ‘off’ the attention is deflected from the picture itself.

• Balance – Consider a garden which only has trees on one side. It looks unbalanced, almost heavier on the one side. The same is true for a room. Imagine an open plan room with bulky lounge furniture on the one side and a delicate dining suite on the other side. The ‘weight’ of the room will be out of balance.

As you can see, if used correctly, these principles will help you create an appealing decor. Design principles are a check list for success and once you master them you will understand how and when to break them.

Space PlanningPlanning your space properly helps ensure that the contents of the room are suitable for the space. It is important to remember that form should follow function when planning a space. How you place the furniture in a room will determine the mood of the room and whether it is comfortable and calm, or cramped and awkward.

The best way to get a feeling for the amount of space available or the size of furniture is to experience it. Move around in the space, pull the chair back and sit at the table and take note of the space around you and behind you. Will you be bumping elbows with your dinner guest? Is there enough space to get out and go to the bathroom without disturbing them? Or sit on the couch and lean over to get your coffee off the table. Can you reach it comfortably? How much space between you and the table is just enough?

If you take into consideration style, design principles and space planning before making any big décor purchases you cannot get it wrong. And if, after you finished your project, one side of the room still looks dominated, ‘weight’ could be added through upholstery, object d’art or some additional furniture.

“Insulate above the ceiling, under the floor or even inside the walls to keep cool in summer, warm in winter and to save energy. For the property owner, this means less electricity or gas usage and therefore real savings in your pocket. For the developer, it means total compliance with the specified R-value for the roof, under national building regulations. Because Eco-Insulation resists the flow of heat, less heat will be lost from the home or office in winter and less heat will

Developers and project managers in the various housing sectors are increasingly seeking one-stop solutions to meet SANS 10400 XA regulations, ensure their projects are energy efficient and provide comfortable living space for occupants. The regulations can however be confusing, so we asked Richard Ellis, the General Manager of popular green insulation brand, Eco-Insulation to explain how it really works.

Why eco insulate?

enter the building during summer. As a form of energy, heat always flows to a cooler area, escaping out of the building in the winter and entering the building during summer. Insulation creates a thermal barrier that controls temperature all year round,” says Richard Ellis of Eco-Insulation.

In addition, the developer can add the following benefits to a new home, without breaking the bank to do it: • As well as energy saving, home insulation also

acts as a sound suppressor. In modern noise-laden environments, increasingly more homeowners are soundproofing their homes.

• A well-insulated home will increase its overall comfort and add to its resale value. In today’s times of rapidly rising energy costs it pays now more than ever to insulate and make your home an energy saving home.

Ultimate green building“Eco-Insulation not only offers the Ultimate Climate Control, it is also the ultimate green building product too. It helps the environment and protects you and your family against the intensifying effects of global warming. Visit our website find out about the ultimate green product. The product is also listed on the Specifile online service, where the designer may draw further technical information,” says Ellis.

The brand has developed a great reputation among retrofit clients and developers of new projects, as can be seen by the great number of positive comments on Hello Peter and the website. It is a serious brand that has earned its technical endorsements by standards organisations including the SABS (South African Bureau of Standards) and TIASA (Thermal Insulation Association of Southern Africa). “Ask to see an up-to-date Product Compliance Certificate next time you call for an insulation quote. We were one of the first suppliers to qualify,” advises Ellis.

Best of all, whether it is installed in the home or office, it’s inexpensive. You get payback on your well-spent rands over a period of months and not years.

A combination of rising energy costs that directly affect operating costs for building HVAC systems or domestic air conditioning, climatic changes that are underpinning much of the green building imperative, and government legislation that prescribes a minimum energy performance for buildings are forcing the building designer to look for cost effective solutions. Insulation has been positioned as one of the most cost effective methods on the market.

Insulation is passiveMost insulation types will last the lifetime of the building if properly installed. Installed insulation can provide a payback period of plus/minus three years, depending on the type fitted. There are no ongoing or maintenance costs, assuming the roofs pace or cavity area is sealed from dust, debris and water.

The science of insulationThermal insulation acts as a barrier to the movement of heat, therefore slowing down the escape of heat from a building in winter – outside temperature lower – and the entry of heat into a building during summer – outside temperature higher. Energy is required either to lower or raise the temperatures inside, hence the use of air conditioners or heaters. This is called active temperature control. Once active measures are turned off, a reverse flow of heat happens and the temperature returns to ambient. To maintain a given temperature considerable continuous energy is required. Insulation reduces this energy loss.

Heat moves through a wall or inside the roof space by any of the following means:

• Radiation – caused by direct incoming sunlight;• Convection – caused by the current in air;• Conduction – caused by heat moving across

touching materials.

Eskom, various technical or trade associations and local governments have been advising property owners to insulate their buildings.

ABC of insulation

Info sites:W www.tiasa.org.za/Technical.htm

The movement of heat is controlled by all these means – especially convection and conduction. Insulating materials can act as radiant, convective and conductive barriers. Certain commonly used materials such as foil insulation operate almost exclusively to the control of reflective heat. The purpose of bulk insulation is to trap a dormant layer of air inside a stable fibrous insulation layer. This works by trapping a large volume of air that slows convection and conduction. Air is a poor conductor of heat. Insulation board works similarly. Naturally, drafts must be sealed.

The R-value is an insulation parameter that is the inverse to the thermal conductivity of a material. So the lower the thermal conductivity of insulation, the higher will be its R-value. “R” = resistance to heat flow. Higher R-value = greater insulation. The R-value is disclosed for most products. R-values offer a comparative basis for comparing insulating materials for both similar and non-similar materials although the installed thickness must also be considered.

However, building regulations require that an R-value be calculated for the roofing or walling system. This incorporates the individual R-values of the insulation, building material used, air gaps and roofing material, where applicable. These complex R-values are readily calculated and much information is available on the industry websites.

Polyaspartic compounds belong in the chemical category of aliphatic esters that are chemically bonded with polyuria and are closely allied to the production of polyurethane paints. Coatings made from these substances have low to zero VOC emissions and are highly stable in the presence of UV and sunlight, meaning among other things that they have a strong resistance to yellowing especially when used as a topcoat. Other benefits of these compounds in coating include variable curing times that allow for the development of high solid coating systems that are easy to apply and long lasting.

When concrete is being coated, it is possible to apply both clear and pigmented versions of polyaspartic coatings. It is also possible to incorporate broadcast media, including quartz, vinyl paint and metallic pigments on site.

Robex SA, an industrial flooring solutions provider with over 22 years of service in the local market, was recently awarded a licence from HP Spartacote® to apply their full line of polyaspartic concrete coatings in South Africa. These next generation flooring systems, manufactured using patented Dual Cure® technology, present a quicker, longer-lasting and more durable coating solution ideal for high traffic commercial and industrial areas.

In addition to epoxy floor coating and Methyl Metacrylates (MMAs), Robex has now added polyaspartic concrete coatings to their service offering, giving specifiers, architects and other construction professionals access to high performing flooring


Robex SAT +27 11 892 2604E [email protected] www.robex.co.za

solutions that are designed to provide quicker drying times and hard-wearing characteristics for both interior and exterior applications.

Combining physical drying and fast chemical curing with moisture cure coating technologies, these revolutionary protective flooring systems offer exceptional direct to substrate adhesion, thin film protection, excellent gloss and colour retention, fast water resistance, longer overcoat intervals and high installation efficiencies.

Since its entry into the industry, polyaspartic coatings have become the preferred choice for application in airports, car dealerships, grocery stores, large retail outlets, warehouses, distribution centres, mechanical shops and many other industrial applications because of its inherent ability to maintain its aesthetic appearance over time, even after continuous wear from heavy machinery.

Superior strength and durability means that coatings will need to be replaced less often while significantly enhancing the life-span of any structure. Furthermore, Spartacote® coatings are also environmentally friendly, contributing to sustainable construction and development initiatives.

Twenty-first century home-builders are confronted with new challenges as we face the impact that our homes have on our environment.

Trending at Cersaie 2013 Tile Africa shares its visit with To Build

Tile Africa Contracts attended Cersaie 2013, the tile and bathroom ware industry event held annually in September in Bologna.

Last year the exhibition featured a total of 900 exhibitors representing 35 countries, and saw more than 100 000 visitors take in the best of what’s to come in terms of technology, innovation and trends in the tile and bathroom furnishing industries. “The size of this exhibition is well over 150 000 square metres so you can imagine the immense variety of exhibitors and their wares on display,” says Tile Africa’s Marketing Manager, Richard Nuss. “It’s imperative for us as a brand and supplier to visit shows of this nature as it helps us source products that are in line with international trends and make them available locally, thus showing our dedication to providing our customers with the best products that are at the forefront of technology and on par with our global counterparts,” says Nuss.

Wood was the major theme at Cersaie 2013 with wood-look tiles in all shades, forms and sizes. 3-D tiles were also prominent and these tiles will make inroads into commercial projects locally.

“There is a noticeable leap in technology allowing for exquisite printing and finishes on tiles and bathroom ware. Many of the trends were evolutions of emerging trends from the previous year, with macro trends now taking centre stage and becoming main stream,” he says.

Top tile trends noted

Bigger formats Large format tiles were prominent, with traditional tiles featuring modern patterns and evolving in shape to include rectangular tiles as well as interlocking tiles that resemble a puzzle.

A touch of texture3D-like tiles and tiles with relief finishes and typography prints are anticipated to be a cyclical trend in line with other trends in the decor industry. Playful optimismThis trend features colourful cartoon strips and Andy Warhol inspired prints on tiles, from rectangular tiles to large-format square tiles that fit together to form an eye-catching feature wall. Deep in the woodsTaking centre stage at Cersaie 2013, these are increasing in popularity, especially to create seamless spaces with floor and wall applications that replicate the warmth of wood thanks to advancement in inkjet technology. Medium and lighter shades of wood are prominent features of this trend.

Texture One of the unique aspects of tiles at Cersaie 2013 is the application of textile-like patterns. “This is definitely a recurring trend and in line with mainstream fashion and design. We foresee that curved tiles will have a commercial application. In terms of patterns there will be a strong return to tribal like design which is further accentuated with extreme texture,” says Nuss.

Other trends in texture that were noted include tiles resembling carpets, while fashion designers

branched into home decor too with the likes of Roberto Cavalli who showcased shimmering gold leopard print tiles.

Colour Neutral colours remain popular including the colour grey which has been a constant feature over the past five years. Nuss says that the evolution of this trend can also be seen with metallic and cement finishes. Other colour trends that will feature strongly especially on the commercial side include various hues of yellow and green.

Bathroomware trends – a futuristic techAdvancements in coating and printing technology allow for taps to be coated in a matt black finish – this trend is currently visible in car coatings. Futuristic looking taps and showers feature extremely thin and super flat spouts in minimalist design lines. Nuss says that new designs are constantly pushing the boundaries of what is possible, with ‘smart homes’ increasing in popularity. Avant-garde experimental design has become main stream such as lights that are smaller with LED lighting leading the pack.

“Modern design keeps evolving in line with technological evolutions and this may seem like a trend reserved for pioneers in industry, but it will certainly feature more prominently in everyday homes,” concludes Nuss.

In a persisting depressed property market with difficult to secure credit finance, property-owners are struggling to obtain market related prices for their assets. Therefore they are renovating in an effort to get the most out of their investments. It’s a case of adding value by adding improvements, according to leading shutters supplier, Plantation Shutters.

One effective and innovative way of improving a home is by adding shutters. Plantation Shutters can define areas within a home, enclose an outdoor area for multi-use, and control light and temperature. In addition, shutters are robust to help secure your home and add an element of style to your home.

Good looking and secureThe company’s range of aluminum security shutters are designed and manufactured to be the most stylish and strongest adjustable louvre security shutters in South Africa. Shutters can be opened or closed completely with adjustable louvres to suit personal preferences. They can be used as window or door coverings, room dividers or to enclose patios and terraces.

During summer and winter, shutters provide protection from the elements including the sun’s heat and glare, and insulate rooms from the cold by providing an extra layer of warmth and protection. The shutters are rigid, will not rattle in the breeze; and provide privacy from the outside world, while still allowing light and airflow in.

Hold back the sun The introduction of low-solar absorption powder coatings on the Plantation Security Shutter is Plantation Shutters’ contribution to the conscious movement of architects and homeowners to approach design in ways that seek to minimise negative environmental impacts with the efficient use of energy and materials. This approach to reduce solar absorption will help to reduce the effects of global

warming along with a phenomenon known as urban heat island – a negative effect on communities caused by increasing summertime peak energy demand.

Individuals can help to counteract the heat island effect with the use of reflective building materials, and now reflective powder coatings on houses, roofs, pavements and roads. The use of such materials can also lower energy demand, air-conditioning costs, air pollution and help promote a better quality of life.

Plantation Shutters design, manufacture and install superior quality, custom-designed shutters. These shutters are installed at some of the top celebrity and designer homes, hotels and restaurants in the country. The company offers a 21 working day turnaround time from order to installation on their timber products, and a 28 working day turnaround time from order to installation on their security shutters. Products come with a standard five year guarantee.

For many architects and building professionals who can recall the launch of the fax machines in the mid 1980s, the times will have changed enormously. That an architect or designer could sit in a different office or city from the client, fax a concept to that client, only to have the client mark-up changes and fax revised drawings back to the architect was a remarkable advance that surely took a number of courier companies out of business. It revolutionised the way things worked back then.

Now it is the time of the mobile office, the home office and more recently the mobile device as an office – something that enables the user to work while standing in the queue at a local Starbucks! Many professionals don’t venture out with laptop computers any more. Instead, along goes the iPad or another famous brand tablet device that does everything… or does it?

Increasingly today the best means of communication has become imagery – the good old fashioned photograph. So what is being done to integrate words with voice with pictures?

The field is very broad. At the Green Building Council’s Convention late last year, techno trends whizz, Dion Chang spoke about the “phablet”, essentially a device that integrates the mobile handset and a reasonably capable tablet device that can be carried in the jacket pocket. Bob O’Donnell’s TECHnalysis Research has come out with some new data projecting that phablets such as the Galaxy Note 3 and the Nokia Lumia 1520 are becoming increasingly popular to the point that they will surpass sales of tablet and notebooks in the not too distant future.

For many designers and building professionals who don’t want to own or who can’t afford to carry around devices, a phablet might be the best answer to these portable office needs.

This is also where another essential device comes into its own – the camera. Contractors, engineers and designers will surely agree, there is nothing more graphic and precise than a photograph taken on site. What is needed however is something more

high-powered than popping off a few pics on your cellphone and sending them over GSM to your office or client. Up until recent times the integration of sending accurate (high resolution) photos conveniently and efficiently with cellphones and other tablet devices has not been great. However, now there is the birth of “phonetography”. Embodied by handsets such as Sony Xperia (running Android), a number of professional photo journalists are carrying these devices in the field – sometimes with no cameras or laptops. It is possible to purchase stand-alone strap on wireless camera lenses (with sensors) that can be operated remotely from the cellphone/phablet “back” when the situation calls for accurate and high resolution photography. Photo touch ups and other editing services are now available on your handheld device so you can prepare the image for upload without reverting to the office. With the abundance of high speed cellphone signals and area wi-fi communication, your upload times for images are both efficient and quick, and you may add extensive text to support your images.

Does the property market know their legal obligations?Ancedotes and allegations of irregularities in the issuing of Certificates of Compliance for electrical and other installations on immovable property came to our attention during 2013, hence To Build decided to investigate. We asked two leading organisations, the Electrical Contractors Association (ECA) of SA, representing qualified electrical contractors, and the South African Bureau of Standards (SABS), representing the originating standards authority, to comment. Both organisations were very forthcoming and helpful and in particular, To Build thanks Cecil Lancaster of the ECA.

The problemWhile there are a number of regulations applying to new developments or rebuilds, there is a level of confusion around the transfer of existing property in the residential market in particular.

How do standards arise?Under the Standards Act, 2008 (Act 8 of 2008) the SABS has been given a mandate to develop, promote and maintain South African National Standards (SANS) and to render conformity assessment services to enable the efficient functioning of the economy.

However, while the SABS has a mandate in the development and maintenance of national standards, the organisation has pointed out to To Build that it is important to note that the electrotechnical field

also consists of voluntary standards. Some of these standards are called up in legislation upon which these standards then become mandatory.

The legislative frameworkThe SABS comments that all low-voltage electrical installations on premises have to comply to the Electrical Installation Regulations (R 242, 6 March 2009 Occupational Health and Safety Act, 1993) issued by the Department of Labour. According to the ECA, the Certificate of Compliance (CoC) dispensation is grounded in the Occupation Health and Safety Act (OHSA), Act 85 of 1993, and the Electrical Installation Regulations (EIR) from 2009. Section 22 of the OHSA regulates the sale of certain articles and prohibits their sale unless they comply the “prescribed requirements”.

Sub regulation 7(1) of the EIR 2009 prescribes that every user shall have a valid CoC, keep it current, and not sell (the building) if the CoC is older than two years. “This implies that all law-abiding users should always be in possession of a valid CoC, and would only need to obtain one for purposes of sale if it is older than two years. In such a case a supplementary one to the existing, verifying its validity and safety requirements may suffice,” says Cecil Lancaster, the Regional Director for the ECA’s Bosveld Region.

What about prior/existing installations?According to Cecil Lancaster, “It is prescribed in 9(2)(b) that existing installations can be certified as being compliant to the basic safety principles of the

prescribed standard and be reasonably safe when properly used and not be subject to full compliance to the latest regulations. Considering that CoC’s issued for sale of properties generally reside under existing installations, and the minimum legal requirement is that it complies to 9(2)(b) as above.”

According to the SABS, the regulation that applied at the time of (original) electrical installation applies. All alterations/extensions to existing installations should comply to the regulation in place at the time of alteration.

The ECA comments that it is always advisable to upgrade where safety is involved. However it should not prevent the CoC from being issued. There exists an area where what is ethically correct for the seller is at odds with what is legally correct when properties are being sold. It is, for example, quite legal for a seller to remove all his/her light bulbs when vacating the premises. While it remains good practice to ensure these things work at handover of the premises, if they do not, and the seller refuses to pay, it would not prevent the CoC from being issued.

Potentially this is where confusion exists in the property owner sector. It is possible that some over-zealous electrical contractors could advise the client (seller) to upgrade the installation in question to the more recent standard.

“In our experience, most electrical contractors are doing their utmost to maintain a fair and reasonable balance between the parties. However there are definitely others that see the issuing of CoC as an opportunity to generate business and make money. A few to the point of excess. We are investigating and reporting these to the authorities as we come across them,” comments Lancaster.

ExceptionsIn cases where a property is purchased for extensive refurbishment, the law allows for the purchaser to relieve the seller of their obligations to provide an up-to-date CoC by confirming in writing that sufficient steps will be taken to comply with all relevant regulations after the rebuild.

New propertyIn the instance of new installations, the advice is much more clear-cut. In terms of sub regulation 5(1) of the EIR 2009, no person may do or allow installation work on his installation in contravention to the prescribed requirements. This includes the requirement that

all work must be a registered contractor in terms of sub regulation 6(1), which determines that electrical installation work may only be done by registered contractors. In addition, 5(2) all materials must comply, and 5(4) it must be done under general control of a registered person.

Green power on the horizonAccording to the SABS, it is currently expanding the national standards to accommodate “green energy sources” and equipment associated with that, including the requirements for electrical connectivity to photovoltaic energy sources in individual homes. By introducing the requirements in the national standards, it will also be covered by the regulations that reference the applicable standards.

To Build hopes to unpack issues such as these in successive issues, since they are complex. In the next edition we will explore the matter further with the National Regulator of Compulsory Specifications, which is the body responsible for statutory requirements.

Basic design conceptsLighting design generally considers the following main factors:• Whether the lighting is required for indoor

or outdoor purposes;• Whether it will be in a safe or hazardous area;• The required illumination level for the task

to be performed;• Working plane level at which the recommended/

required lux is to be achieved;• Type of lamps to be used and their lumen outputs;• Mounting height/provisions available;• Uniformity to be achieved; and• Colour rendition acceptable for the task.

Closed and open areasThe lighting application is referred as indoor or outdoor depending on whether the lighting is in a closed or open area, meaning the protection to the luminaires against atmospheric and environmental conditions like weather conditions, corrosion, etc. It is also possible that indoor luminaires are adopted where there are no side walls but only ceilings are provided (pump sheds and so forth). Note, no contribution from natural light is considered in the calculations.

However for design purposes and for better energy savings, the maximum possible natural lighting used to be considered in early generation building designs. These approaches have however changed considerably with modern designs. Nevertheless, the reflectance factors play a major role in improving the lux levels.

Light fittings for outdoor areas should be made of enclosures and materials to withstand the weather conditions and corrosion factors associated with the location. No reflectance factors are considered in the calculations in these situations. More attention is paid on focused lighting and localised lighting in areas where specific tasks are to be carried out.

Working plane and mounting heights• The working plane in a reading area or an assembly

shop level can generally be at desk level (about 750mm to 900mm from finished floor level) but for a verandah or an indoor stadium, it can be floor level itself.

• The light falling on the working plane will depend on the mounting height of the lamps.

• The indoor lighting is affected by the cavities above the mounting height (ceiling cavity) and below the working plane (floor cavity) as well as the walls surrounding the area.

Reflectance factors• Reflectances are given the abbreviations L, M and

D to signify light, medium and dark reflectances respectively.

• The average values of these factors for ceiling, walls and floor are generally considered as per table below.

• The coefficient of utilisation (COU) factors given by the manufacturers is generally based on these reflectance factors for different room indices, for use in indoor lighting calculations. The COU is the ratio of the luminous flux that reaches the working plane to the total flux emitted by the lamps, taking into account the floor and ceiling cavities as well as the reflectances.ACDC Dynamics have a technical lighting specialist

and designers on hand to assist with any requirements that readers of To Build might have.

Founded in 1949, Bulthaup has evolved to be a global leader in the premium kitchen sector. An independent and family owned and operated business, the business is now entering its third generation. Bulthaup carries the name of its founder, Martin Bulthaup and true to its origins in Aich, nearby to Munich, product is still manufactured at its Germany factory and exported to locations around the world. To Build visited and conducted a photoshoot at the company’s first African showroom that opened in Cape Town early in 2013. The shop is located fashionably close to Cape Town’s Cape Quarter precinct along Somerset Road.

The company embraces sustainability – kitchens built to last – that tend to eschew short-lived trends and focus on timeless elements that integrate with the entire living area. Material used echo that philosophy – solid wood and aluminium – long lasting.

Building kitchens for styleIconic international brand gaining traction in SA

According to corporate philosophy, no two Bulthaup kitchens are the same. Not only because each one is designed and manufactured in line with the unique requirements, lifestyles and traditions of the users in question, but they also leave their own personal stamp on their kitchen – making use of the space, live their lives in it, and make it their own by adding items over time. Thus their product range includes a selection of accessories and utensils arranged according to the function they serve: preparation, cooking, presentation, storage and washing. According to Ramón Casadó, Bulthaup’s designer in Cape Town, function informs design. And no detail is left unattended.

The company has rolled out projects across the globe, from single kitchens to famous hotels and 500-unit installations that include luxury apartment complexes and resorts.

At the core of the current range are three distinct design themes. Theme b1 is design-minimalist – a focus on key elements, everything within reach, linear and a highly aesthetic look. Theme b2 is an open mobile kitchen concept including a workbench, mobile cabinet and the household appliance unit. There is much focus on mix and match. Finally, b3 is a free-design concept that makes use of the walls as hanging space. Maximum use is made of open space that provides what the company refers to as a “floating effect”.

The South African Institute of Steel Construction (SAISC) has awarded local supplier, Marley Pipe Systems with the Stewart & Lloyds Light Steel Frame Commendation for their role in the successful construction of the Saint Helena Worker’s Village.

Saint Helena Worker’s Village Project pipedSouth African supplier wins prestigious award for remote location project.

The award-winning Saint Helena Worker’s Village Project came about following a £250 million investment by the UK Government to construct an international airport on the British Overseas Territory of Saint Helena, an isolated island situated in the South Atlantic Ocean. The airport, which is expected to cater for flight routes between Saint Helena, London, Cape Town and Johannesburg, is anticipated to boost the island’s tourism industry and promote economic growth for the future. Due to the remoteness of the island, however, the construction meant that a worker’s village would need to be constructed to accommodate the 300 employees that would be working on the project for the duration of the contract.

The logistical and environmental challenges that the island presented meant that materials had to be carefully selected to comply with stringent transportation requirements.

With this in mind, Marley was commissioned by SA Steelframe Systems to supply their Marley Equator hot and cold pipe materials for installation in the village, which includes accommodation, ablutions, recreational facilities, laundries, offices, as well as a kitchen and cafeteria. With their unique push-fit PE-X pipe system for hot and cold water applications, Marley Equator, has long been celebrated in the industry for being SABS tested and approved, less labour intensive, and being low maintenance. These factors, among others,

made Marley Equator the contractor’s preferred choice for use in the project.

As there would only be a boat available to transport materials to the island once a month, Marley had to work closely with SA Steelframe Systems to calculate the amount of materials needed for the construction, as a shortage of materials would have resulted in costly delays for the project. After careful inspection of the plans, Marley presented a Bill of Quantities which turned out to be the exact amount needed for the construction – with no additional materials needed nor arrangements required to return excess stock.

To assist further in speeding up the installation process, Marley provided value-added training and support to local labourers who would be installing the system in the form of training tools and resources

developed by Marley. This had a significant impact on the successful outcome of the project as many of the workers had little or no previous experience in the installation of plumbing systems.

Owing to the project’s limited time constraints for construction, ease of installation was one of the key deciding factors in choosing the Marley Equator system which is a stellar success.

The natural durability of our commercially grown species like Pinus and Eucalyptus, is low, rendering it susceptible to insect and fungal attack. It is imperative to preserve the timber.

There are two types of wood preservation; primary (industrial) and secondary (DIY). In primary preservation, wood is pressurized with an industrial chemical wood preservative e.g. CCA, TBTN-P or creosote. This process increases the long term durability and resistance to fungi and insect attack. Primary preservation is prescribed in SANS Standards, Compulsory Specifications and Building Regulations.

Secondary preservation is used for supplemental (preventative) and/or remedial (corrective) purposes and applied by hand, e.g. treating previously untreated timber or exposed ends of machined pressure treated timber. Protective wood sealers or varnishes are not regarded as secondary preservatives unless they contain active ingredients (biocide). Without active ingredients such finishes merely protect against weathering i.e. moisture and UV rays, and not fungal and/or insect attack.

Primary preservation of timber is categorised into ‘H’ classes for different end-use applications.

Be sure to choose the correct H class of treated timber for your intended application and apply remedial preservative to all cross-cut and exposed areas (except for ground, fresh water or marine applications). Apply a suitable wood sealer when the natural non-weathered look of the exterior timber is desired.

When planting a pole or post do not plant them inside an encapsulated concrete base. Instead, use a ‘collar’ or compacted stone and soil with or without a solid (cured) concrete base.

How to plant a pole/postAs a safety precaution when machining CCA treated wood, wear a dust mask, gloves and safety glasses to protect your eyes. Do not make baby toys, furniture, food utensils or store food or water in containers made from CCA treated wood. CCA treated wood should also not be used in beehives or used for animal litter where it may become a component of animal feed.

Treated timber waste is not regarded as hazardous waste material and should be disposed of at a registered disposal site. Do not burn treated wood off-cuts and do not use it for firewood or for food preparation.

A spirit of adventure is felt at Camp Discovery, where humans and wildlife embrace the beauty of the natural surroundings of the 270-hectare game farm. However, when the wildlife began to pose a problem by roaming onto the sports field, Camp Discovery approached Khulani Timber Industries, who provided a solution by installing Tanapole™ ranch fencing around the perimeter of the field to alleviate the problem.

Established in 1991 and located in Modjadjiskloof in Limpopo, Khulani Timber Industries is a leading treated pole producer for the building/fencing pole market and the agricultural/transmission pole market throughout Africa.

The installation took two weeks and features an interesting entry/exit design that eliminates the use of a traditional gate that would open and close. A skillfully designed “zig-zag” formation of the poles allows for humans to navigate their way on and off the field, while keeping the wildlife at bay. To withstand the outdoor conditions of the sports field and provide protection against wood decay caused by fungi, the poles were treated with Tanalith™ C wood preservative and Weatherwood™ water repellent additive.

The treatment of timber poles is carried out in two treatment plants, one of which was upgraded and commissioned by Lonza Wood Protection in 2010. All poles adhere to the SANS 457 pole specification requirements. Khulani is also listed on the Tanalised™ Wood Preservative Guarantee programme, which offers end-users, such as Camp Discovery, the peace-of-mind of a product that is backed by a 15-year guarantee.

A thought leadership piece from Dulux

Making sustainable choices in decorative coatings

Dulux Trade South Africa recently hosted a number of exclusive seminars across the country, in order to share its singular message relating to green technology and sustainability, to an audience of professional architects, engineers, specifiers, contractors and more within the South African commercial property industry.

Currently ranked number one in the chemicals super sector of the Dow Jones Sustainability Index (DJSI), leadership through sustainability is a critical element to AkzoNobel’s long-term, competitive advantage strategy. Dulux Trade South Africa takes its lead from

our Amsterdam-based parent company AkzoNobel. The South African company is currently following and fulfilling a five-year tactical approach, which focuses on five central pillars including: Products and Services; People and Communities; Waste and Resources; Energy; and Transport and Travel.

Established in 2007, the Green Building Council of South Africa (GBCSA) is definitely gaining traction and momentum, with the number of Green Star SA certifications doubling year-on-year since 2009. As a silver founding member of the GBCSA, Dulux is encouraged to see green building specifications and

features being adopted by so many players in the built environment. The levels of self-regulation, compliance and acceptance, as well as the significant difference these adopted regulations are making to the local build environment are creditworthy.

The compilation and delivery of Dulux’s ‘Sustainable Choices in Decorative Coatings’ seminar, underpins our company’s commitment to responsible, ethical and sustainable trading. We found that the market is enthusiastic. However, it often lacks awareness on which products will maximise the environmental benefits for green accreditation, without having to sacrifice performance and pay an exorbitant premium for the certification.

Our aims for the collation and delivery of this seminar content were twofold:

• Firstly, to outline the key issues involved in choosing paint based on sustainability grounds; and

• Secondly, to explain the wider impacts of the decorating process on the environment.

We found that audiences from Johannesburg to Cape Town were incredibly receptive and appreciated, in particular, the immense value in the emphasis placed on three fundamental aspects relating to sustainability and paint.

In short, every decision-maker should ask the following three questions when evaluating the eco viability of a paint solution:

Dulux TradePrea Moodley T + 27 11 861 1000

• How long will it last?• How much will I need?• What is in it?By unpacking our collective global knowledge and

international proficiencies, supported by local cradle-to-grave manufacturing processes; many attendees were unaware of our comprehensive green offerings spanning: products, services, advice and expertise. Specifically, the innovative Envirowash System and Light & Space, based upon Lumitec paint technology.

The positive responses garnered from the ‘Sustainable Choices in Decorative Coatings’ seminar, has confirmed our initial assessment of the gaps, which currently exist in industry awareness and understanding. There are a host of products and services available within green star categories, which exhibit the very same quality and durability, and without the drawback of a substantial price premium attached to them.

The company will continue to host this seminar and drive the change in industry thinking – products should not be manufactured and applied, at the cost of the environment, nor shareholder value.

a.b.e. Construction Chemicals has launched a new, unique bitumen heat-fused waterproofing membrane produced by the leading Italian company, Index, which a.b.e has an exclusive agreement with for product distribution in SA since 1996. Indeed, two million rolls of the Index bitumen waterproofing membranes have been sold since in South Africa.

New Armodillo protects

The new product called, Armodillo, is a multi-functional polymer-bitumen membrane that offers waterproofing, drainage and the protection of foundation walls in a single product application.

The company’s Brand Manager for waterproofing, Lance Anderson, says: “These new Armodillo polyester membranes incorporating anti-root protection, can solve the problems of waterproofing, mechanical protection, and drainage. All this with a single product.”

“Armodillo’s upper face is armoured with impact-resistant, elastic polymer-bitumen ‘dimples’ or bubbles –similar to the protective plates of a (live) Armadillo’s shell – that protect the membrane from perforation when buried, and at the same time form an efficient drainage network that allows any water to quickly drain to the perimeter drains, stopping hazardous pooling. If the dimples are torched, they become adhesive, making it possible to bond insulating panels, non-woven fabrics and other materials on to the membrane.

“The lower face of an Armodillo membrane is covered with Flamina, a plastic film that can be easily torched. The bubbles on these membranes keep the installer’s hands away from the torch, making installation much safer and easier. Index Armodillo can be installed by bonding the next membrane onto the

70mm indented selvage of the previous membrane ensuring that no raised, uneven problematic laps are created,” says Anderson.

The product can be used on both flat and vertical parts of a building, and for ground foundation walls as a protective and draining layer. It was recently installed at a roof garden test site at the University of Cape Town.

“There is potential for the product as a simple-to-use waterproofing solution for both roof gardens and below-ground tanking areas. Its multi-functionality substantially reduces multiple product applications to reduce time on site. Its multi-functional membrane has far greater puncture resistance than conventional HDPE membranes,” Anderson states. Armodillo membranes are covered against product failure by Index’s 10-year insurance-backed warranty that incorporates excess-free claims should a product-related failure occur.

Case study – prestressed hollow-core slabs for security

A two-section 275m high-strength security wall, reaching 5.4m at its highest point and 0.6m underground.

Gauteng manufacturer, Echo Prestress, has erected a security wall built with its own prestressed hollow-core concrete slabs at its prestressed hollow-core factory in Chloorkop. Constructed in two sections, the wall is 275m long with its highest point reaching 5.4m. A 0.6m section of the wall is buried below ground.

Interlocking slabsThe walls comprise five tiers of interlocking slabs

measuring 6m x 1.2m x 150mm, which were placed horizontally and secured into position between vertical steel columns.

The company’s marketing director, Melinda Esterhuizen, says there are several advantages to this type of walling, speed of construction being one of the major considerations, cost being another. “The current cost of building a security wall using prestressed hollow-core slabs is considerably more economical than an in-situ wall offering the same properties; an in-situ wall would take two to three times as long to build with no advantage gained in strength or durability.

Prestressed concrete is a method for overcoming concrete’s natural weakness in tension. It can be used to produce beams, floors or bridges with a longer span than is practical with ordinary reinforced concrete.

Prestressed concrete has the ability to carry greater loads and span greater distances while maintaining a minimum cross section. This factor gives the designer more freedom to open up spaces by using larger spans, and by using smaller sections. It also provides economy by requiring fewer supporting members, thus increasing speed of construction as well. The net effect is a sound, durable, non-combustible, premium structural system.

How is prestressed concrete achieved?Prestressed concrete is achieved by stretching high strength steel cables or strands between two fixed abutments, then casting concrete on a form that is placed between the abutments. The concrete is allowed to cure, which creates a bond between the cables and the concrete. After the curing process, the cables are cut free of the abutments, causing the cables to try to relax, thus compressing the concrete.

What is prestressed concrete?

Moreover, precast walling has no requirement for shuttering or propping, onsite curing, formwork or grouting, and the construction rate is approximately 50 linear metres per day (eight hours),” she says.

High strengthThe Echo wall comprises 50MPa concrete which means even jack hammers would struggle to break through it.

“Intruders cannot scale it, dig under it or break through it without making a great deal of noise and taking a very long time,” says Esterhuizen.

Esterhuizen advises that soil conditions determine the type of foundations required for this type of walling and whether the slab placement should be horizontal or vertical. “Clay, collapsible soils, high-water tables and so on require horizontal installations, whereas better soil conditions are best suited to vertical applications. However, wind and impact resistance influence the placement decision as well and some

horizontal installations require piling. Moreover, impact resistance also determines wall height and slab depth.”

“Stormwater drainage must be properly engineered and weep holes, generally 100mm in diameter, should be placed strategically for good drainage,” states Esterhuizen.

Green attributesEsterhuizen added that precast security walls also have some green attributes. “The concrete slabs and steel support columns are both 100% recyclable and reusable. The wall itself has a very long life span, is maintenance free, and other than occasional cleaning, no other maintenance is required. However, the steel columns do need rust protection.”

“Key to the success in constructing this type of security wall is a very close working relationship between the design, engineering and construction professionals. We offer design solutions for both precast flooring and security walling applications,” she concludes.

Stable is a collection of innovative South African design. Designers, artists and artisans from every corner of South Africa showcase their work alongside one another in a professional retail environment. Started by designer and television presenter, Aidan Bennetts, and featuring some of his work, Stable is an eclectic collection of original work from both established and upcoming young designers.

The origins of Aidan’s work are wrapped up in the story telling aspects of the diverse South African culture and in the special place that being in the home occupies. “We sit outdoors, we soak up the sun. We cherish dinner table conversations and have friends laughing in our lounges. Our homes mean more to us than I have found in other cultures,” says Aidan.

He believes that South African people have suffered, persevered and have come out determined and strong. “We will surprise any visitors with the wonder of what we have in our country – the level of development, the kindness of our people and the talent of our craftsmen. We know where we want to go

and we work with others to get there. We are open to change. South Africa as a place is full of inspiration. Increasingly not just South Africa, but Africa as a whole is starting to be a continent which provides inspiration for New York catwalks and international trends. Whilst the East has dominated much of the headlines, Africa too is rising,” he says.

There is a variety of other featured designers at Stable – each an expert craftsperson in their own right.

In his recent State of the Nation Address, President Jacob Zuma said, “In 2012 we unveiled the National Infrastructure Plan, led by the President through the Presidential Infrastructure Coordinating Commission. We have subsequently invested one trillion rand in public infrastructure over the past five years. Many of the projects are completed or are nearing completion.” He declined to present the programme of action for the current financial year, stating “that programme will be presented by the new government after the elections”.

“While the construction industry is grateful for the contribution the government has made, it is disappointed that there are no plans, as yet, for it to continue in this vein,” says Rob Johnson, Executive Director of the Master Builders Association of the Western Cape (MBAWC), a registered trade association for employers in the building industry.

Reassurance needed He continues, “The industry is still recovering from the effects of the global recession and needs to have some measure of reassurance that the government, regardless of whether it remains in the hands of the ANC or is taken over by another party, will continue to support it. Government is in the best position to deliver a consistent workload to the construction sector and thereby reduce the effects of economic cycles. Our industry has the capacity to absorb large numbers of unemployed people, and thus enable the development of skills, if a steady workflow can come from government.”

Skills and development“In terms of training and skills development, we commend the government’s achievements, particularly the increase in the number of enrolments at tertiary level, the much-improved matric pass rate and interventions aimed at bettering maths and science. We also applaud their efforts to make further education more accessible both through the National Student Financial Aid Scheme and the construction of additional FET Colleges,” says Johnson.

The Master Builders Association in the Western Cape shares its views on the State of the Nation.

“We will continue to support government’s efforts through our artisan, skills and bursary programmes. However, these can never be on the scale required to service the industry as a whole,” he adds.

“It is our hope that the party elected on the 7th of May 2014 will continue to build on the foundations laid by the current government,” concludes Johnson.

Lafarge South Africa, the world leader in building materials has proudly announced that they are the new sponsor of the University of Johannesburg’s Civil Engineering Student Society. This three year sponsorship is one that goes far beyond the simple branding of a building – it’s an important partnership of support, training and skills development. “We at Lafarge are very proud to partner with the University of Johannesburg (UJ) in contributing to creating highly valuable human capital. Today’s students are tomorrow’s leaders and engineers, who help to shape our country and ultimately build better cities,” says Desmond Maharaj, GM of Lafarge Cement in South Africa.

The South African operation is the local presence of the international Lafarge Group. Hence, the company will provide a deeper insight into the world of civil engineering to the UJ Civil Engineering Society, a student organisation for engineering students. This will be achieved through technical presentations, the supply of products for students to help complete practical applications as per their course requirements, and to raise funds through events such as the upcoming Annual UJ Civil Golf Day in April.

Fact finding visitsThe UJ Civil Engineering Society will visit other universities that offer engineering courses in order to experience their facilities and to learn more about their courses. Lafarge will be supporting these initiatives wherever possible.

The first will be a site visit for final year students to the Lafarge plant based in Moscow, Russia, later this year. This destination has been chosen because of the significant civil engineering work being undertaken in the city. As a member of BRICS (Brazil, Russia, India, China and South Africa), Russia is one of the world’s major emerging economies and, as such, offers a wide range of infrastructure development, which will

The education and training of South African scientists and engineers is a national priority and so it is a welcome occurrence when a major corporate rolls up their sleeves and gets involved.

The square where the official sod turning for the new tertiary institution took place in September 2013, was a pilot/launch project. Currently located in the middle of a sports field, it will ultimately act as a “middle space” between a number of new buildings which are being constructed. On the square, a blend of 100 000 nutmeg piazza and onyx pavers, supplied by Corobrik, were laid to create an iconic public square forming part of the new campus’ first phase. Measuring 3 000 square metres, the square is a multi-use space that includes seating. The aesthetic is that of a gathering space with public art on display.

Campus facilities will be designed by foremost SA architects, selected via the Sol Plaatje University architectural design competition run by the DHET.

According to Qonde, the campus design “is also expected to reflect the essence of the university, which represents a new order of African intellect with a firm focus on innovation and excellence and our powerful spirit of democracy, inclusiveness, growth and opportunity.”

The Sol Plaatje University will occupy a combination of existing and purpose-built structures in the inner

The Sol Plaatjie University development in Kimberley, South Africa’s first post-democracy university has been heralded as iconic and inspirational, “embodying the South African public’s aspirations”, says the Director General of the Department of Higher Education and Training (DHET), Mr Gwebinkundla Qonde.

city of Kimberley including the civic centre, parts of the Oppenheimer Gardens and surrounding buildings, as well as the former Cape Provincial Administration building. The central and highly visible location in the inner city is expected to make the institution a landmark and prove extremely convenient.

Named after struggle stalwart, Sol Plaatje, the campus is expected to be complete by 2015 at a final costing of R6 billion. It is expected to enroll 5 000 students starting with a modest intake of 150 in 2014.

Corobrik’s Commercial Director, Musa Shangase, said that nutmeg piazza and onyx pavers were mixed in a ratio 70:30 and, whereas, usually a herringbone pattern is used for projects of this nature, a stretcher bond pattern was used. The simplest and the most frequently used pattern, stretcher bond tends to look more rectangular and pavers can be laid very accurately with perfect alignment and consistent joints for a very formal aesthetic. This bond suits designs where the eye does not need to be strongly led and works well with header courses – brick pavers running at right angles and in rows mixed in the same or contrasting colours. It will enhance the surrounds and blend well with established, older buildings. Clay pavers are also skid resistant, easy to lay, easily recycled and can be “unzipped” to gain access to underground services for repairs or maintenance and can then be “rezipped” using the same bricks without leaving a “scar”. “Corobrik is proud to be associated with a project of this calibre,” says Shangase.

A range of Bayferrox pigments, produced by Lanxess Inorganic Pigments, was extensively used in the design and construction of Plaza de la Libertad, a new landmark and iconic structure in Medelin, in central Colombia.

Lanxess Inorganic Pigments – based in Germany – is one of the largest pigment suppliers to the global construction industry. Chryso Southern Africa is the sole distributor of Lanxess inorganic iron oxide pigments for the South African construction industry and has a colour laboratory in Jet Park that can measure the colour strengths of pigmentation, and provide customers with specifications to colour-match available concrete masonry production lines at competitive rates.

Medelin’s 12 000 square metre Plaza de la Libertad features two towers (24- and 17-storeys high) resembling tall tree trunks, designed to blend in with the surrounding forest’s trees and their trunks and barks. The design is by architect/designer, Alejandro Toro Posada. It features concrete, coloured with Bayferrox pigments, to add natural inspiration and employs the building’s wings as branches resembling giant ‘trees’.

These structural elements are based on a temperature-regulating and extremely weather resistant concrete coloured with 60 metric tons of Bayferrox 918 LOM yellow pigments in the main building, and seven metric tons Bayferrox 130 M (red) and 318 M (black) pigments in the auditorium. A major benefit of using integrally coloured concrete is that the facade will require no follow-up maintenance.

Designer Posada adds: “Furthermore, the facades have been designed to conserve resources, reducing conventional air conditioning and lighting costs by around 40%.”

The avant-garde building accommodates government institutions, a business hotel, TV studios, businesses, cultural centre, open-air theatre and exhibition halls. Described as a “place of expressive power”, it has won top prize in a major international competition organised by the National Association of Architects.

The use of colour pigmentation added to concrete structure brings synergy with nature.

Concrete tree trunks add colour

Hannes Engelbrecht, Chryso SA Business Manager: Concrete Aesthetics, says there are some vital factors to consider when producing pigmented concrete including: • Cement: Portland cement can vary significantly in colour – from light to dark grey. This change in colour can influence the final colour of pigmented concrete. “That is why it is important to use the same cement throughout. The higher the cement content, the more intense the colour,” Engelbrecht explains. • Aggregates: The colour of aggregates also influences the ultimate colour so it is important to ensure that the entire surface area of the aggregate is coated with the pigmented cement paste for colour uniformity.• Mixing water: Water dilutes the colour of the pigments in the mix and excess water evaporates from concrete, leaving behind pores that scatter incidental light and lighten the colour of the pigment.• Formwork: The type, colour and condition of formwork can influence surface colour. Formwork with different rates of absorption will create surfaces with different colour shades. • Dispersion: The pigment must be mixed with the aggregate before the cement is added. • Temperature during drying: In higher temperatures, fine crystals develop in the cement matrix and determine how the light that falls on the concrete is scattered. Smaller crystals produce lighter pigment.• Efflorescence: Admixtures with high levels of calcium chloride can cause primary efflorescence.

The Chryso Southern Africa Group provided a variety of products to the site of the revolutionary “House Rhino”, now under construction near Port Elizabeth and regarded as one of the most sustainable residences yet designed in South Africa.

Chryso SA supplied admixtures and waterproofing products, while its sister company, a.b.e. Construction Chemicals, provided a special waterproofing slurry onto site. Rhino Plastics Managing Director, Brian van Niekerk’s new “green” house is currently under construction at Crossways Farm Village, just off the N2 near Thornhill.

been described as a “benchmark model” for integrated energy systems. It has been widely publicised, features on YouTube and has attracted the attention of architects, builders and students from many parts of the world.

Included in its unique features is an aqua garden incorporating a natural water-treatment plant linked to a rim-flow pool, natural lighting, double-glazed windows, water-based under-floor heating and cooling, a roof that generates solar energy, and electrical energy stored in a large battery set. Rainwater is harvested and treated before reuse; effluent water, organic waste and grass cuttings are processed by a bio-digester to yield cooking gas for the home; and the primary building material is low carbon footprint, insulating concrete form (ICF) and created from interlocking expanded polystyrene.

A significant part of the Crossways development is the removal of foreign vegetation and the re-establishment of natural coastal belt thicket and fynbos. Rainwater is harvested from angled roofs and street pavements, and water from the village’s sewage treatment plant feeds into a man-made bird reserve wetland.

Well waterproofedPatrick Flannigan, Commercial Sales Manager of Chryso in the Eastern Cape, says the company supplied CHRYSO Fuge B and CHRYSO CWA 10 pore blocking waterproofing products for concrete filling of the internal openings (core fill) as well as the ponded areas such as swimming pool, cooling ponds, and garden water features.

“CHRYSO Fuge B makes mortar and concrete highly resistant to capillary action and reduces or eliminates infiltration of water under pressure. The fine particles in CHRYSO Fuge combine with the lime in cement to form water repellent particles to obstruct the capillary action within the concrete,” Flannigan explains. “The product’s CWA 10 version is crystalline-based and has exceptional crack-bridging capabilities.”

To counteract problems experienced with the quality of Eastern Cape sand in the concrete mix, the company supplied CHRYSO Air 7, the company’s air-entraining admixture for mortar to Rhino Plastics. The

product helps to improve the workability of concrete and minimises segregation in pre-mixed mortars where harsh sands have to be used. “This admixture can also reduce or eliminate the need for lime in masonry applications,” says Flannigan.

Finally, super-plasticiser, CHRYSO Fluid Optima 175, was supplied to concrete supplier, Denron, for the self-levelling mix used for the polished concrete floors around the pool area. No compaction was used during vibration to prevent “pasty” areas caused by stone settling to the bottom of the slab. CHRYSO Fuge B was also used here to waterproof the mix.

a.b.e. Construction Chemicals, also part of the Group, provided the project with a.b.e.’s duraflex which was applied to protect the exposed edges and wall tops of the structure. Duraflex is a flexible waterproofing slurry based on a special synthetic resin dispersion and a blend of selected cements mixed with carefully graded aggregate.

Going green and saving costs are paramount to the success of any business today. As such, investing in thermal insulation and energy-saving techniques has become the norm in today’s business world. Saint-Gobain Isover, a market leader in the sector, has completed a life cycle analysis and independently verified EPD on Glasswool.

Save up to 78% of energy

Buildings typically account for 40% of all energy consumed in countries, yet the potential to save energy is huge. It is possible to save up to a staggering 78% of a building’s energy consumption for heating and cooling by using savvy thermal insulation and energy saving techniques.

Saint-Gobain Isover, with over 55 years of experience in the insulation market, is a leader in the manufacture of thermal and acoustic insulation. It is

committed to producing energy efficient insulation solutions that improve buildings’ thermal and acoustic comfort, while simultaneously helping the environment by reducing greenhouse gas emissions.

Isover has two local manufacturing sites that employs over 240 people who are responsible for producing a wide range of insulation materials including Glasswool, Ultimate and Expanded Polystyrene (EPS).

To remain innovative and ahead of the pack, in 2008, Isover South Africa upgraded its production facilities, installing the latest TEL fiberising technology which allowed for improved quality and performance of fibres and has increased production capacity by 30%.

Glasswool, Ultimate and EPS are manufactured according to ISO 9001 Quality Management System standards and Isover’s Springs plant achieved ISO 14001 certification in 2012.

GlasswoolEnergy efficiency improvements have been one of Isover’s main focus areas for many years, and this is clearly illustrated when comparing the tons of Glasswool produced in 2000 to current day production where energy consumption has dropped by 20% per ton with an equivalent reduction in CO2 emissions.

In addition, water consumption per ton of Glasswool produced has been reduced by 30% through the utilisation of closed circuit systems and investing in new equipment that consumes less water. Glasswool can be compressed by a factor of up to 10 which saves on storage and reduces transport costs.

Glasswool is one of the most popular widely-used environmentally friendly, stable and sustainable insulation materials available today. It is made from a combination of naturally occurring silica sand, fluxing agents and up to 80% of recycled glass.

Isover’s Glasswool range provides excellent thermal and acoustic insulation solutions that improve the

energy efficiency of buildings. Glasswool has a zero Ozone Depleting Potential (ODP) and no CFC`s or HCFC`s are produced in the production process.

SagexSagex is Isover South Africa’s foams division that manufactures a range of expanded polystyrene which offer a choice of lightweight, high compressive strength and water resistant insulation solutions for use in industrial, commercial and domestic applications.

Sagex EPS is recyclable and is manufactured using a pentane blowing agent which ensures that the product is CFC and HCFC free.

The green conclusion Over their useful life Isover’s Glasswool and EPS insulation products save more than 100 times the energy consumed and CO2 emitted in their manufacture, transport and disposal.

National Treasury published section 12L on 8 November 2013 in Government Gazette No. 37019, which puts into operation deductions of energy efficiency savings in terms of the Income Tax Act of 1962.

Income tax incentive for energy savers

This long-awaited announcement is welcomed by the Certified Measurement and Verification Professional (CMVP) industry. The CMVP industry has been advising clients for a while that the release of the Act was imminent and to prepare for it.

Finance Minister, Pravin Gordhan, gave notice last year that that section 12L of the Income Tax Act, 1962 (Act No. 58 of 1962) – deduction in respect of energy efficiency savings – as inserted by section 27 of the Taxation Laws Amendment Act, 2009 (Act No. 17 of 2009), amended by section 27 of the Taxation Laws Amendment Act, 2010 (Act No. 7 of 2010), and substituted by section 29 of the Taxation Laws Amendment Act, 2012 (Act No. 22 of 2012), would come into operation on 1 November 2013.

Section 12L allows deductions to be calculated at 45 cents per kilowatt hour, or kilowatt hour equivalent, of energy efficiency savings. A person claiming the deduction must obtain a certificate issued by an institution, board or body prescribed by the regulations. Such bodies can be found on the

South African National Accreditation System (SANAS) website www.sanas.co.za.

To claim for energy efficiency savings from National Treasury the regulation requires that a baseline must be set at the beginning of an assessment year with a reporting period of the energy use at the end of the year of assessment, and that such savings calculations meet the full criteria and methodology used to calculate energy efficiency savings. No double dipping is allowed, which means concurrent benefits in respect of the energy efficiency savings may not be received.

Qualified personsTo find persons qualified to provide measurement and verification (M&V) services, the Council of Measurement and Verification Professionals of South Africa (CMVPSA) an independent professional measurement and verification body that represents the South African M&V industry, may be approached. They ensure that the quality of M&V services and service providers are credible, trustworthy and transparent. Their website is www.cmvpsa.org.za.

The Energy Training FoundationW www.energytrainingfoundation.co.za T +27 41 367 1041

The CMVPSA upholds the highest standards and requirements for M&V in accordance with the Efficiency Valuation Organisation (EVO), and the International Performance Measurement and Verification Protocol (IPMVP). This is the internationally recognised protocol for performance M&V and provides a consistent, reliable approach to M&V around the world.

Sole training organisationThe Association of Energy Engineers (AEE), in cooperation with EVO, established the CMVP training programme. This programme is locally presented by the AEE’s sole training partner for the Southern African region, the Energy Training Foundation (EnTF). EnTF is also an Energy and Water Sector Education and Training Authority (EWSETA) training provider, and the affiliated training provider of the Southern African Association for Energy Efficiency (SAEE). The CMVP qualification requires attending a two day intensive M&V training course, writing and passing the prescribed international examination on the third day, and passing the examination with a minimum of 70% within the required time allowed. Thereafter a candidate may apply for certification to the local CMVP Board, which will review the candidates’ current

qualifications and experience in the M&V industry. After a positive recommendation by the local board, a recommendation is made to the AEE’s international CMVP Board for certification. The AEE keeps tight control over the quality of candidates who are certified, in that it requires certification be maintained via ongoing education and providing proof of this for re-certification purposes every three years.

The AEE has been developing the energy engineering field for over 36 years. In total the AEE is active in 90 countries with 14 000 Certified Energy Managers (CEMs) whom are collectively active in every single continent in the world, and just short of 3 000 CMVPs in 28 countries.

The EnTF presents CMVP training throughout the country at various venues. The organisation’s website contains details of the next scheduled courses on the continent. CMVP training carries three CPD credits with the Engineering Council of South Africa (ECSA).

Eskom’s dedication to ensuring there is enough energy to keep South Africa powered up has seen the implementation of impactful national programmes since 2004. These energy saving initiatives and interventions include:

• Offering incentives and advisory services in support of customers in the industrial, commercial and agricultural sectors taking a decisive step towards energy efficiency by replacing energy intensive technologies with energy efficient solutions, and adopting optimal energy usage behaviour patterns in their organisations.

• Encouraging homeowners to switch off electrical element geysers, pool pumps and unnecessary lights and appliances between 5pm and 9pm, the period of peak demand in South Africa when the residential sector’s energy consumption increases from 17% to 35%.

Saving energy of crucial importance all seasons of the year says Eskom.

Save energy during all seasons

<Pics> <Stock energy saving pics / lightbulbs. GG Will see what he has, also.

• Rolling-out two nation-wide technology exchange initiatives – the Compact Fluorescent Lamps (CFL) Exchange and Residential Mass Roll-out Programmes – in the residential sector; with more than 60 million energy saving CFLs installed in homes nation-wide since 2005, the CFL Exchange Programme is the biggest residential energy efficiency roll-out of its kind in the world.

• Offering industrial and commercial customers an option to curtail loads at short notice through the Demand Response measure, a dynamic energy infrastructure management programme designed to support the stability of the national electricity grid.

Demand management initiatives and energy savings programmes have realised a demand reduction of 3 587 MW since 2005, which is equivalent to the output of a power station with six 600 MW generators.

Integrated Demand ManagementEskomW www.eskom.co.za/idm

Despite these impressive savings, the supply of energy is likely to remain tight for the next few years. And, although the situation will improve from 2017 when most of Medupi’s units will be on line and Kusile will have started supplying power, South Africa will not experience a significant surplus of power due to a growing economy and a rising demand for energy in the industrial and residential sectors. In addition, almost two thirds of Eskom’s power stations are past the mid-point of their expected operating lives and they, therefore, require higher levels of planned maintenance work. Like any engine, generating plants need routine maintenance or upgrades that require them to be fully or partly taken out of service.

Saving energy throughout the year in all sectors of the economy will remain strategically important for the foreseeable future. “With power generation maintenance scheduled to continue through March 2014, electricity supply will be as constrained this coming autumn as during summer. The business sector – where the use of heating, ventilation and air-conditioning (HVAC) systems is high this time of year – has the greatest potential to reduce the demand for energy by using these systems more efficiently,” commented Andrew Etzinger, Senior General Manager of the Integrated Demand Management department at Eskom.

Five tips for reducing energy usage by HVAC systems include:• Proper maintenance: Ensure that all system components – including motors, pumps, fans, compressors, ducting and filters – are intact and work efficiently; proper maintenance not only conserves energy but also extends the lifespan of equipment and prevents costly breakdowns. • Minimise the temperature difference:Keep the thermostat setting at 23°C in summer.• Reduce the cooling load by keeping heat out: - Close windows and doors when air-conditioners are

on. - Install and place ceiling insulation, window glazing,

reflective blinds, awnings and door-sweeps to reduce heat gains.

- Switch off unnecessary lights, appliances and equipment, which emit heat that could add to the cooling load.

• Adopt electricity smart habits: Encourage wise use of HVAC systems amongst facilities managers and employees – everyone should follow these guidelines: - Only switch on air-conditioners in rooms that are

occupied.- Use air-conditioner fans to draw in and circulate cool

air from the outside during the early morning hours.- Set air-conditioners to re-circulate cool air instead of

drawing in warmer air from the outside.- Switch off units 30 minutes before staff leaving the

office. - Adjust blinds and curtains in rooms that receive

direct sunlight – it helps to keep rooms cool and postpone switching on the air-conditioner.

• For larger systems:- Use air-conditioner fans to draw in and circulate cool

air from the outside during the early morning hours.- Set air-conditioners to re-circulate cool air instead of

drawing in warmer air from the outside.- Consider replacing old systems – new, energy

efficient systems offer enhanced control functionality and higher levels of energy efficiency.

Sustainable goals for the futureAchieving sustainable built environments with low impacts on the natural environment is becoming a universal goal. Energy usage in buildings is under the spotlight. Water wise projects are most likely to get the go ahead. That’s why an in-depth understanding of the environmental constraints and impacts of technologies on architectural solutions is emerging so important for students of architecture. It is the resolution of environmental issues that can be expected drive the architectural expression that will shape tomorrow’s buildings and the creation, extension and redevelopment of our towns and cities.

The revitalisation of an abandoned mine shaft in Johannesburg wins a place for Dylan Watkins of the University of Johannesburg in this year’s Corobrik sponsored Architectural Student of the Year Awards (ASYA).

Dylan Watkins is pictured proudly displaying his Award received in the University of Johannesburg regional finals of the Corobrik Architectural Student of the Year.

Lauren Moll of Corobrik said that the sponsors of the ASYA had seen many changes in architectural expression, and anticipated that the growing consciousness and responsibility towards environment will lead to architecture being increasingly grounded in environmental resolution, which will translate into designs. Tomorrow’s leading architects will therefore not be just great designers but will be well rounded in the technologies for achieving sustainable architecture. This movement is evident in the students’ thesis projects in recent years and students are increasingly up to speed and pushing the boundaries of design. Moll announced that this year’s regional winner, Dylan Watkins, and his project Shaft No. 2, runners up Marc Sherratt and Francois Mercer, and winner of the prize for best use of clay masonry, Rachel Wilson, demonstrated that future architects were embracing the sustainability agenda with environmental issues achieving equal status with functionality and aesthetics.

Re-scripting the third landscape Watkins has re-scripted the future of Johannesburg’s third landscape through architecture of the ‘Terrain Vague’, a term for abandoned spaces or former industrial areas. He identified Shaft No. 2, an isolated and historic site, situated between two mine dumps on the southern periphery of the Johannesburg Central Business District as one of these scenarios. His dissertation attempts to pioneer an architecture uniquely developed from the third landscape. The site, Shaft No.2, is grounded within a large urban context surrounded by existing urban systems. The aim is to assimilate a hybrid architecture which integrates nature, people and architecture into a new urban ecology to revitalise the site as a socio-ecological urban system where architecture is an interface for exchanges,

resulting in ecological observatories as the main architectural programme. The architecture will not only aid in the process of re-scripting the third landscape, but also becomes a platform for exchange where knowledge can be obtained and shared through the tracing and recording of the landscape and climate influence.

Watkins said, “I propose that architecture is used as an instrument for remediation; more specifically of existing situations, scenarios and spaces in the built environment which are noticed but overlooked.”

A focus on biodiversityMarc Sherratt’s entry is entitled ‘Replenishing biodiversity at Melville Koppies Nature Reserve’.

This dissertation’s research problem is diminishing biodiversity in the urban context of Johannesburg, the particular focus being on the endemically endangered Cape Vulture (Gyps coprotheres) and how architecture can facilitate its conservation.

The building is a rehabilitation and breeding centre for the Cape Vulture designed to disappear into the ancient landscape of Johannesburg’s past, Melville Koppies. The architectural idea is “building as a cliff face”. Due to the important discovery that the on-site electricity pylons were needing replacement, the architecture reused these vertical lattice towers as horizontal elements to create journey of birth to release.

Rehabilitating a waste landscape Francois Mercer’s thesis, CultuREscape, is a suburban cultivation school addressing the rehabilitation of a waste landscape in Roodepoort.

Mercer says, “This dissertation explores my own neighbourhood – Roodepoort. It examines consumerist lifestyles, which dominate the area and proposes a building to showcase new modes of living.” She proposes a cultivation school and a ‘hackerspace’ where residents of Roodepoort can learn to live sustainably and collaborate. The school recalls Roodepoort’s history as a farming area and celebrates the area’s spirit of place.

Revisiting history Rachel Wilson’s ‘Identity Tower’ re-scripts Newtown, Johannesburg as an echo of the larger inner-city strategy. “Originally a town where clay bricks were made by the working class and used in construction, my aim was to revert to the original history by using clay bricks to maintain Newtown’s identity,” says

Wilson. The fusion of traditional clay brick paving with the undulating soft landscape expresses the history and future identity of Newtown, represented in the Identity Tower.

Each regional winner is entered into the national finals in March 2014 where the winner will receive R50 000.

“Corobrik has for a long time regarded the role of the architectural community as key to defining the ultimate integrity of our built environment and for creating time honoured spaces that people feel comfortable to be in, are uplifting and relevant to those who use or witness them,” says Moll.

Achieving energy efficiencyDirk Meyer, Managing Director of Corobrik, said that achieving energy-efficiency that was central to the new National Building Regulations SANS 10400-XA:2011 defining the energy usage of buildings required that architects revisit the passive solar design concepts and techniques of yesteryear, and where it may be appropriate enhance these with new technology able to add value with economic payback.

As an example SANS10400-XA recognises the role of thermal mass, thermal comfort and energy used for heating and cooling defining a minimum R-value of 0.35 for masonry walls, however thermal modelling shows how the incorporation of higher R-value insulation materials between the brick skins moves clay brick walls towards optimal thermal efficiency and comfort, supporting low life cycle energy costs and low total life cycle costs.

Cederberg Wine Cellar is Africa’s highest altitude vineyard at 1 100m above sea level. Situated at this relatively great altitude for a vineyard and being fairly remote from the city means that the farm has to employ some interesting sustainable initiatives. Being remotely located in the Cederberg range, it means no cellphone signal and the trip to connect with the N7 national road from the farm takes an hour and on a rough road best travelled in a robust vehicle with offroad tyres. Thereafter it takes another two to three hours to journey to the city. This does not deter winemaker and farmer, David Nieuwoudt and his family. His wines are highly acclaimed internationally and he has won the Gold at the premier Decanter Wine Awards in London several times, as well as numerous other distinguished awards. David practices sustainable farming methods and he is also fortunate that the altitude means that the vineyards are virus-free. He also farms several hectares of the exclusive vineyard, Ghost Corner, in the Cape Agulhas area. Following the harvest, these grapes are brought to the Cederberg Cellar in the mountains for wine-making.

While it is not top of mind to associate a vineyard with a built environment, one has only to consider the cellar itself, which has to be just right to allow for the making of excellent wines.

To Build recently visited this cellar, which was undergoing an extensive refurbishment. In order to minimise temperature swings, which are a big factor in a location such as this – hot days and cold nights – David has extensively insulated his new cellar. For the outer cladding, the basic corrugated sheet walls have been refinished with beautifully sculptured clay face bricks to give the building a new world winery effect. This heralds an iconic structure that will serve the Cederberg brand for years to come.

If the opportunity presents itself, be sure to try out these award-winning wines.
