Integrated fire protection and security at UCT res A ground-breaking new integrated fire and security protection system now ensures the safety of residents and visitors on the premises of a new University of Cape Town residence. Words and photos by Gareth Griffiths Early in 2012, Obz Square â&#x20AC;&#x201C; a major mixedgender residence â&#x20AC;&#x201C; opened its doors to students, offering accommodation for up to 990 students in independent single en suite rooms. The building is located on Main Road, Observatory, and has seven storeys above ground with two levels of basement parking. Special and progressive features of this building include female-only floors and highly specialised electronic systems that enable universal access for the disabled. The primary contractor, Neil Muller Construction, moved onto an existing brownfield site during 2010 and started works, including demolition and site clearing. The project, for client Cape Living Developments and ultimately for end-user UCT, took just 20 months to complete as it was a fast-track project with tight deadlines. The completed building accommodates 900 students in single rooms and house wardens in independent apartments, with a mixed-use zone for retail and resident facilities on the ground floor. The additional two levels of basement parking allows for up to 1 000 vehicles. As a high occupation density building with a sensitive mix of occupants in a busy street, building security, including fire and physical security, is of paramount importance. Consulting engineers Solution Station designed a sophisticated fire and security protection system with technical advice and input from FireSpec. As the fire and security systems consultant and contractor, FireSpec was responsible for the installation. The system was installed to tight deadlines before handover of the building to the client late in 2011. The systems are a good example of integrated security, fire and other low-voltage security systems.

project focus FireSpec CEO Leo Slootmans explains that besides being able to undertake the installation right through to sign-off, they were also able to become involved at the design stage, which greatly aided the process of integration. “The systems are an outstanding example of integrated security and fire low-voltage security systems,” he says. As one of the final-stage contractors on site FireSpec worked to a very tight schedule to ensure project completion on time. The work was signed off by Cape Town’s Fire Chief in November 2011. It is significant that the contractor was able to become involved at the design stage. This greatly aided the process of integration. Integrated systems include: • access control • fire detection • fire suppression • CCTV • PA systems • evacuation systems • integration of air conditioning, lift signals and access control for the accommodation • centralised monitoring of alarm systems, air conditioning, fire escape doors and intercoms. Undertaking a tour of the behind-the-scenes security in the building one becomes aware of complete 360° planning and attention to detail. Backing this is cutting-edge modern technology, a testament to how effectively the security and fire system industries have tapped into modern IT and electronics technologies.

The control room

All security, fire detection and other controls feed through to a centralised control room located in the main lobby near the main turnstiles. Students use their encoded access cards to move around both campus and the residence building. The building controllers have access to separate control units for each system, including evacuation, intercom, access point control and CCTV monitors. Behind the control room is the electronic/server support room, which is access-controlled and fire-protected. It contains the electronic nerve centre for the functioning of these services.

CCTV, fire detection, Evac and PA systems

These are located at all central positions such as common rooms and walkways. Fire detection units are visible outside the ceiling board. Special detectors are also located behind the partition walls or ceilings in order to provide early warning of smoke when it travels out of sight through the cavities.

Living quarters and special needs areas

Intercom points predominate all the main passageways, of which a number are universally accessible to allow easy usage by persons in wheelchairs. There is also a unit in each universal

access room. These communication services are independent of Evac systems and allow controllers to freely converse with individuals making the enquiry. Visitor and other announcements are made via well-positioned loudspeaker units on each floor. The building planners went to exceptional lengths to make the building both safe and accessible to the disabled. For residents with physical challenges or handicaps, there are special needs rooms. Special panic buttons are installed in the toilets for the disabled. In addition, there are no fewer than six refuge zones where persons with disability may converge to find a safe location pending evacuation. From the ongoing and operational safety perspective, the high standards set by the building planners are expected to continue with the appointment of FireSpec as responsible for ongoing system servicing and maintenance. FireSpec’s executive in charge of the UCT project, Cecil Meyer, tells us this impressive building is just part of an ongoing roll-out of electronic system integration across all buildings within UCT. “Such engineering services and maintenance programmes are available to all potential clients nationwide, in addition to certain African countries. We encourage clients to appoint service providers with the right levels of expertise and accreditation, such as described in the Obz Square case history”, he remarks.

South Africa’s Standardisation and Quality Assurance service provider of choice As South Africa strives to grow the economy, create jobs to alleviate poverty, and limit environmental impact. The SABS is set to play an important role, and has the ability to face these challenges: • • • • • •

6 years of accumulated standardisation 6 and conformity assessment experience Visionary leadership 150 accomplished Test Auditors 350 qualified Test Officers A new leading-edge laboratory complex completed in 2011; and A footprint that covers South Africa and extends way beyond its borders.

Markets, business models and the climate may all be changing, but our mission remains; to enable efficient functioning of the economy and the environment, through standardisation and quality assurances. The SABS is a statutory body that was established in terms of the Standards Act, 1945 (Act No. 24 of 1945), and continues to operate in terms of the latest edition of the Standards Act, 2008 (Act No. 29 of 2008), as the national institution for the promotion and maintenance of standardisation and quality in connection with commodities and the rendering of services.

SABS Standards Division It is of paramount importance for South Africa to create a competitive industry that will keep pace with the fast changing face of the world economy, where globalisation, increased competition and technological innovation have become the new parameters to drive economic progress, sustainability and employment for its citizens. The role of SABS Standards is to develop and maintain relevant South African National Standards (SANS) and other normative documents to support this.

During 2010, a detailed study was done to benchmark the SABS with other national standards bodies. It revealed that the business model needed to be reassessed in order to improve its ability to deliver appropriate standardisation solutions for South Africa. The analysis has resulted in the division’s development of a strategy which will enable the organisation to play a more pivotal role in the following areas: • E xpanding International Trade: South Africa’s prosperity depends on international trade facilitated by standard and conformity assessment practices. • Stimulating the South African economy: The correct application of standards and related conformity assessment practices can reduce the regulatory burden, ease trade barriers and create efficiencies in all sectors of the economy. These efficiencies will support the government’s economic development plans. • Supporting a Green Economy: The reduction of greenhouse gas emissions is pertinent on the country’s agenda. The development of South African National Standards to support this initiative is high on the agenda of SABS Standards. Green businesses require standards to participate in the global supply chain – creating confidence that we, as a country, are striving towards a green economy.

SABS Standards identified five key objectives to achieve our vision of becoming the trusted standardisation and quality assurance provider of choice. • Develop and maintain market relevant national standards that support the competitiveness of the South African Industry and facilitate the protection

of health, safety and the environment. A clear message must be communicated on the valueadd of standards. • Maintain a transparent and impartial standard development process that promotes wider participation for all sectors of industry. • Acquire and develop skills through the introduction of sector specialists and strengthening the expertise within technical committees. The SABS will focus on the broadening of the pool of experts available to improve the sustainability of technical committees. • Expand the understanding, recognition and use of SANS, by partnering with a wide stakeholder base in order to promote the value of standards and the idea that standards are effective tools in the implementation of public policies and good governance. • Maintain and increase our regional and international standardisation influence in promoting South Africa’s views and interests in standards development. SABS Standards is committed to delivering on Government interventions and policies such as IPAP II.

Building & Construction SABS is a leading business services provider to organisations worldwide, offering a range of services for management system certification, product testing and certification, and standardisation. This includes the standardisation in the field of manufacturing, conversion and testing of building and construction, including all aspects of their effects on man and his environment, relating to activities in the following fields; civil and construction, for example steel and concrete works, and the building industry, for example bricks, paving blocks, roof tiles, and cement concrete products. The primary activities carried out in this sector ensure that components and systems produced by the building and construction industry comply with the relevant standards. We also won the internationally advertised tender to perform third party quality and testing services on behalf of the Malawian government.

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

Energy Efficiency in Buildings

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

How do consumers react when energy costs go up or when availability is limited? The consumers simply opt for generating energy from other sources such as solar, generators and others. Why not save instead of generating? Everyone has a right to live and work in a safe environment. The main drivers for energy use are comfort, safety and security. Comfort in buildings constitutes heating, cooling, ventilation, lighting and acoustics. The SABS recently published two groundbreaking standards to assist government, municipalities,

advertorial builders, property owners and the like to ensure better energy efficiency in buildings going forward. SANS 204 - Energy efficiency in buildings The main objective of SANS 204 is the reduction of operational energy use, without reducing comfort. Compliance with SABS 204 will reduce the use of energy from electricity, gas, oil, or other fuels used in buildings. The standard further addresses energy use by the building’s services to operate it, but excludes energy used in manufacturing/construction or energy use by portable appliances. Drivers for energy use – comfort, safety and security – the right to live and work in safe environment SANS 204 requirements reduce the use of energy from electricity, gas, oil, or other fuels used in buildings for heating, cooling, ventilation, hot water (heating and sanitary), and other services. When the requirements of SANS 204 are properly applied, energy efficiency can be obtained in one of the following manners • Insulating or shading the building fabric • Controlling heat flow through the building envelope and glazing • Reducing air leakage through building fabric • Creating internal air movement for cooling • Improving efficiency of heating, cooling and hot water systems.

SANS 10400-XA - The application of the National Building Regulations Part X: Environmental sustainability Part XA: Energy usage in buildings Much standardisation work has already been done around individual energy-saving devices such as energy-efficient light bulbs and solar water heaters. Instead of reinventing the wheel, SANS 10400 Part XA incorporates these existing standards into a holistic overview of the entire construction process, which then serves as a single reference to help architects, building construction companies and other stakeholders to ensure that their buildings comply with energy efficiency requirements as described in the standard. SANS 10400-XA is a single reference for stakeholders to ensure compliance with energy efficiency requirements as per the NBR, and gives further requirements for: • The orientation of the building, with well-used areas facing North to make best use of natural sunlight and warmth; • Suitable roof overhangs to keep out the high summer sun, but let the winter sun, when the sun is lower in the sky; • Sensible fenestration (windows) to let in light and sun, but not so much that natural warmth or coolness cannot be retained; • The use of appropriate heating, ventilation and air-conditioning installations where required; and • Solar water heaters become mandatory with new buildings being erected.

Dispute Resolution Service

Tackling disputes through legal channels in the property and construction sectors is expensive and often leads to severe delays in major projects. To minimise these issues, alternative dispute resolution is increasingly being adopted, and it will soon be mandatory for all legal cases to go through a mediation process before they can be set down for trial. In support of the SA Government’s Mandatory Court Mediation scheme, RICS has developed an internationally accredited mediation programme, specifically designed for professionals (legal and non-legal) working in the built and other environments. This non-residential training programme consists of two modules delivered over five days. Successful completion of the full programme certifies you as an RICS Accredited Mediator. Graduates of the programme can also apply to join the Southern African RICS President's Panel of Mediators.

Rics: Excellence in property Founded in 1868 and with over 140 000 members worldwide, the Royal Institution of Chartered Surveyors (RICS) is the oldest and largest international professional organisation for the land, property, construction and related sectors. The primary role of RICS is to preserve and advance professional standards. RICS Dispute Resolution Services (DRS) DRS is the division of RICS responsible for providing Alternative Dispute Resolution (ADR) services throughout the world.

What is Alternative Dispute Resolution? The cost of court action is high, even for a winning party, and the process can be inordinately slow. Litigation also often leads to polarisation, damaged business relationships and reputation, especially as court cases are usually open to the public and the media. ADR is a collective description for methods of resolving disputes without the need to go to court. These include arbitration, mediation, expert determination, dispute avoidance boards, adjudication, and expert witnesses.

What makes RICS dispute resolution training unique?

The people RICS train are typically very senior members of the construction industry. These include land surveyors, valuers, quantity surveyors, rental specialists, senior land and property administrators and managers, senior estate agents, architects, engineers, rural development specialists, planning officers, dispute avoidance board members and chairmen, members of utility companies or regulators, members of government departments and local

authorities involved in the administration of land and property matters and legal practitioners – both solicitors and barristers – who specialise in the above areas. RICS dispute resolution training does not of itself impart specialist knowledge in any of these fields: it cannot and nor should it. Their panels of mediators, arbitrators etc. bring their significant pre-existing expertise in their fields to their training courses and they are equipped with the skills they need to act in their chosen dispute resolution role. RICS training function is integrated into its role as the world’s foremost property DR service provider: ultimately they are training people to staff their panels of dispute resolvers around the world.

RICS membership – why join?

RICS members benefit from: • a globally recognised qualification (MRICS and FRICS) • increased career opportunities and earning potential • being part of an international network of property professionals • following a code of conduct and applying practices recognised by the public • lifelong learning • earning clients’ confidence

The Liquefied Petroleum Gas Safety Association of South Africa

What is the LPGas Safety Association?

Established in 1987, the Liquefied Petroleum Gas Safety Association of South Africa is non-profit organisation that represents companies which are involved in distribution, installation, hardware and retailing of LP Gas and gas appliances. The primary aim of the Association is to ensure the sustainable growth of the liquefied petroleum gas industry through promoting safety and compliance with best business practices.

What is liquefied petroleum gas (LPGas)?

LPGas is an exceptional energy source due to its origin, benefits, applications and industry. With an immediate global availability, environmental benefits, its natural by-product origin, transportation flexibility and diverse applications, LPGas plays a pivotal role in the transition towards a more secure, sustainable and competitive energy model. LPGas is a clean-burning, sustainable, efficient and safe fuel, making it an ideal alternative energy â&#x20AC;&#x201C; especially for cooking, water heating and space heating. For more information visit www.lpgas.co.za

Important facts regarding the safe use of LPGas

From a specifier or userâ&#x20AC;&#x2122;s perspective there are three major factors to consider when specifying LPGas:

LPGas cylinders The placement of cylinders and tanks on a site is regulated through the South African National Standards, specifically SANS 10087 Parts 1 to 10. Sites should be correctly designed and laid out taking the prescribed standards and regulations into consideration. LPGas appliances Any appliance distributed or sold in South Africa must conform to SANS 1539, 329 or 347. All appliances which have been tested and found to conform to these standards are issued with a Permit Verification Number and the Safe Appliance Mark by the LPGSASA. Specifying or using appliances which do not comply could result in sanctions by the Department of Labour and/or negating insurance cover. LPGas Installations In terms of the Occupational Health and Safety Act and the Pressure Equipment Regulations, any LPGas installation may only be undertaken by a properly trained and registered LPGas installer. A list of all registered installers can be found on www.saqccgas.co.za

Mellet & Human Architects 2000–2013 Mellet & Human Architects, situated in Pretoria, was started in 2000 by partners André Mellet and Willem Human. Both graduated from the University of Pretoria in 1991 and gained valuable experience in most fields of architecture working for other practices until 1999. At this time the partners realised that to further their careers and creative talent they had to start their own venture, thus Mellet & Human Architects was born. Mellet & Human Architects is affiliated to the South African Council for the Architectural Profession (SACAP), the South African Institute of Architects (SAIA) and the Pretoria Institute of Architects (PIA). Today the practice is firmly established in the upmarket residential sector, designing mostly single-family houses as well as being involved in multi-unit residential developments. Designs are undertaken throughout South Africa, Africa and recently internationally. The combined architectural experiences of the partners also enable them to undertake commercial projects. Being a small office, Mellet & Human Architects offer a personalised, one-stop service. Prospective clients are led by the dedicated team from the initial briefing, design and technical documentation to building plan approval, the appointment of approved building contractors and supervision during construction up to completion of the project.

Design, environment and documentation

André Mellet, in charge of design, believes a successful project is the result of correctly integrating contextual factors with each individual client’s needs, resulting in value being added to the property. Not only is every client different, but each design is influenced and challenged by specific contextual factors such as orientation, vegetation, views, gradient, and privacy from neighbouring properties. Many clients return to Mellet & Human for second or even third projects. This is attributable to client satisfaction and the fact that design solutions offered by the practice are accepted as most suitable for their properties. The practice does not necessarily follow specific architectural styles, but rather is inspired by integrating architectural principles with the client’s aesthetic preferences. This approach results in houses recognisable as Mellet & Human designs. Experiencing a Mellet & Human design should be fulfilling. Rooms are positioned and scaled according to function and the level of privacy required. Characteristics of designs are flowing, well-proportioned, light and airy interior spaces linked to the outdoors. The outdoors is seen as an extension and integral to all designs. Finishes are chosen according to purpose and texture, which add to the overall experience.

Designs are increasingly environmentally friendly and aim to be energy efficient. Climatic factors, the use of solar power, double glazing, rainwater harvesting, inclusion of greywater systems and attention to insulation of the building envelope are integrated into designs. The practice is also a member of the Green Building Council of South Africa (GBCSA), which aims to ensure buildings are environmentally sustainable, effective and healthy. The important task of comprehensive technical documentation and detailing of designs is provided by Willem Human. This helps in correct execution of building work on site by building contractors approved by Mellet & Human for good-quality work. Completed projects have been featured in various magazines and on television.

Awards

The commitment to provide good service was recently recognised when the practice received awards of Merit and Excellence from the South African Institute of Architects and the Pretoria institute of Architects. Awards include the following: 2011: Pretoria Institute of Architects Honourable Mention: House Louw/Delport, Groenkloof, Pretoria 2012: Corobrik/SAIA Award of Merit: House Louw/ Delport, Groenkloof, Pretoria 2012: Corobrik/SAIA Award of Excellence: House Louw/ Delport, Groenkloof, Pretoria

New Residence In Groenkloof, Pretoria Mellet & Human Architects, based in Pretoria, received awards of Merit and Excellence in the 2011/2012 Corobrik-SAIA awards programme for the design of this new house. The project is situated in Groenkloof, an established suburb of Pretoria sought after for its central location, mild climate, large properties, richness in trees and views of the capital city. Today the area is characterised by younger couples moving in and renovating the older properties. The owners of this property, one of who grew up in the area and is a landscape architect, wanted to move from their existing large house into a newly designed, smaller house on a subdivided portion of the property. This subdivision is situated below the

existing house and borders the street to the north and the Groenkloof Nature Reserve to the west.

A challenging brief

The brief called for a compact, easy-living house which had to accommodate an extensive art collection accumulated over the years, consisting mainly of pictures and sculptures by South African artists. Accommodation had to provide open-plan living areas, two en suite bedrooms, a study and sufficient storage space.

project focus It was a challenging brief: the small site is steep and narrow and existing trees and views from the house at the back had to be retained. In favour of the stand are the beautiful views over the capital city, the ideal north orientation and the bordering reserve which is like an extension of the property. The resulting house is like a high-level penthouse absorbing the unobstructed views. The property was terraced in order to provide living areas on one level with basement parking and utilities below. This makes the house barely visible from the street. The house is unpretentious and unobtrusive in its setting against the hill, blending with the existing vegetation. It becomes part of the hill and responds sensitively to its environment. A visitorâ&#x20AC;&#x2122;s ramp from the parking area makes a turn and reveals as a surprise the expansive view through the glass front door. Moving through the house one is constantly aware of this view since all rooms feature a glass skin to the north. Sliding doors open onto wooden decks, linking the house with the indigenous garden, which in effect becomes an extension of the house. The linear floor plan running east-west provides all northern living areas and bedrooms with a gallery. This gallery doubles as a circulation space, linking the public and private spaces, and is also an exhibition space for the collection of paintings. The building has a low profile with strong horizontal lines merging with the land and trees and allows the building at the back to retain its uninterrupted views. The design incorporates clerestory windows that ensure the interior is extensively flooded with natural light, resulting in pleasant living spaces.

Warmth and an intimate atmosphere are created by the choice of materials for the interior and exterior. Natural stone, wood and textured finishes create a down-to-earth ambience. The building essentially becomes part of the hill and responds well in its logical layout and detailing to the climate, slope and views. The house relies on solar energy and gas for cooking, making it environmentally sustainable. The integration of the building to its environment is further enhanced by the well-planned garden designed by the landscape architect owner. The art collection is extended into the garden where powerful sculptures create focal points anchoring the view.

Award of Excellence

The awards bestowed by Corobrik and the South African Institute of Architects recognise, promote and create public awareness of excellence in architecture and is run every two years. The citation by the judges of the awards on the design included the following excerpt: This house conceptually infuses an art and sculpture gallery into a residential dwelling. By taking advantage of the spectacular views surrounding the site, whilst humbly confining itself to an untamed slope of the property, the house becomes a showpiece of unlimited visually captivating site lines. It is often the case that the homes of art collectors are austere with disproportionate interior volumes; a notion turned on its head by this residential building as it evokes a down-to-earth ambience within well-proportioned indoor spaces.

Indispensable style Obbligato design and manufacture an exclusive range of contemporary furniture and accessories to vivify commercial, hospitality, corporate and domestic environments. The company was started 11 years ago when a niche in the planter market was stumbled upon when we manufactured a few planters for our home and started marketing them as a sideline to the busy signage business we owned. From there the orders grew over the following four years to the point where we no longer manufactured any signage because the planter business had taken over the factory and we had to move to bigger premises. The range of products manufactured now include benches/seating, planters and trash bins. Bespoke items to architects’ or interior designers’ specifications can also be manufactured. Products are handmade in materials as diverse as mild and stainless steel, aluminium, copper, perspex, mosaic and fibreglass with emphasis on using sustainable, green materials wherever possible. We develop versatile designs that are suitable for both

indoor and outdoor application, with the focus on creating products that the consumer can identify with on an aesthetic level using simple, elegant shapes and minimalistic elements. Investing in fewer, quality décor items that are timeless is not only more costeffective in the long run but is more environmentally friendly than purchasing cheaper items more often. All products are manufactured in Pinetown, Durban, to order with a manufacturing lead time of four to six weeks for standard products. Products are distributed locally (door to door) by courier and have also been shipped to to neighbouring African countires and internationally – including the USA, UK, Hong Kong, New Zealand, Australia, Spain, Italy and Dubai. We visit international exhibitions regularly to keep up to date with the design trends. This ensures that our products are in line with what is available on the international market – but at a local price. Obbligato products have been exhibited at many local and international exhibitions including Glee 2002, Urban Gardens 2003 & 2004 in the UK and the Chelsea Flower Show, London, in 2007. ‘Obbligato’ literally means indispensable and commonly refers to a musical accompaniment that is integral to a harmony.

24/7 leak detection with AquaTrip AquaTrip is a water leak safety trip switch that will protect your water supply by detecting leaks, running toilets, dripping taps and burst pipes. If a leak is detected AquaTrip will automatically shut off the water to prevent excess water bills, water wastage and property damage.

AquaTrip can tell the difference between normal water usage and a leak. It is fully programmable to suit most properties with no interference to the user and no impact on normal water use. Water lost to unknown leaks, plumbing failures and vandalism wastes billions of litres of water and costs millions each year in excess water bills and property damage. These losses occur every day in homes, public and commercial buildings, schools, universities and on farms. AquaTrip is easily installed and low on cost and maintenance. To give you an idea of the amount of water lost: a fast-dripping tap will lose 31 000 litres per year and a burst pipe 26 million litres per year – or 72 000 litres per day. A toilet with a stuck fill washer could waste 7 000 litres per day or 2.6 million litres per year. These examples illustrate the amount of unnecessary water wastage that occurs worldwide. In the past year AquaTrip made impressive in-roads in getting its product specified by architects, plumbing consultants, engineers and developers as they acknowledge the usefulness of the product.

AquaTrip is SABS Approved and has Water Mark Certification For more info please call Chris 082 716 8020 Website: www.aquatrip.com

During August 2012 CEM® was launched in Port Elizabeth with an inspiring group of delegates attaining impressive pass marks.

Training recognition ceremony for AEE energy engineers in SA A total of 226 delegates underwent Association of Energy Engineers (AEE) training in 2012 with the AEE’s sole training provider for the southern African region, the Energy Training Foundation (EnTF) which is the training division of energy optimisation engineering company Energy Cybernetics. During an EnTF AEE-certification recognition awards evening in November 2012 at Emperors Palace in Gauteng, Prof LJ Grobler, president of the AEE’s local chapter the SAEE, welcomed the latest South African professionals to the distinguished group of individuals that are certified internationally. “After an intensive week-long training session and a gruelling four-hour open-book examination you have no doubt earned the respect of your fellow energy engineering professionals that have been through the same processes to attain certification,” Grobler said. Not only is a 70% pass mark required for the certification examination, but experiential background within the industry also needs to be attained and maintained. The AEE was the first organisation to pioneer energy certification programmes and its recognition and credibility has evolved throughout the world to encompass 89 countries that acknowledge its certification programmes. During the past year Australia has joined the long list of countries and started training for AEE certification. In southern Africa, the EnTF has made significant inroads already and has trained over 1 700 delegates during the past decade. The AEE’s flagship certification programme is the Certified Energy Manager (CEM®). No other organisation can match the AEE CEM® credential, and here’s why AEE certifications are used throughout business and government: • AEE is the only organisation that has been implementing energy certification programmes for 35 years. • It is the only organisation that has certified 10 000 CEMs®. • It is also the only organisation that has certified more than 22 000 professionals in speciality energy areas.

• For optimal control all AEE-certified professionals’ qualifications and eligibility can be confirmed by logging onto the AEE website: www.aeecenter.org/ custom/cpdirectory/index.cfm In southern Africa the EnTF offers the AEE’s CEM® and Certified Measurement & Verification Professional (CMVP®) training and also facilitates the professionals who qualify with the application process for certification registration and renewal of certification. CMVP® was developed by the AEE and the Efficiency Valuation Organisation (EVO). As a building block to this training, EnTF launched the Fundamentals for Energy Management Training (FEMT), a training course without examination to prepare candidates for the basics of electrical, mechanical, energy management and thermal aspects for future training, or for those who are looking for a good grounding in the energy engineering field. Based on the ISO 50 001 Energy Management Standard, EnTF, Certification Europe and DQS South Africa have developed an informative training course for persons of all knowledge levels to understand what the standard and holistic energy management can do for an organisation and how to apply this in line with international best practice. During August 2012 CEM® was held for the first time in Port Elizabeth, and in 2013 Capetonians will have the opportunity to attend the course on their doorstep. EnTF is taking its training to various major cities in the region during 2013, including Durban, Port Elizabeth, Bloemfontein and Cape Town, with the bulk of training in Johannesburg. Dates for these courses can be found on the EnTF website at www.energytrainingfoundation.co.za. All courses are CPD-accredited for Engineering Council of South Africa (ECSA) registration purposes.

South Africa’s greenest green house The bar has been raised by ERA Architects and keeping up with the Joneses means more than matching their flashy car or sending your children to an exclusive private school. By Johan Schronen Photographs: Sinead Brookes

Admittedly the home the Joneses built makes a major statement from the street with its double driveway and imposing triple-volume entrance. But if you’re wondering how you could match or better the Joneses’ lifestyle, just wait until there’s a power blackout leaving your whole neighbourhood in darkness. (Not too difficult to imagine seeing that our national power supplier has been “tripping out” somewhat too often lately.) You’ll be surprised to see their home still brightly lit, with Auntie Eskom’s dizzy spells not affecting the Joneses in the least. So let’s consider how they’ve raised the bar in their neighbourhood.

Ivor Jones has converted an old Hurlingham, Johannesburg, house into an “autonomous” home. It’s completely self-sufficient when it comes to water and electricity and even deals with its own sewerage. Ken Stucke of ERA Architects in Johannesburg, who designed the home, says even if the City Council failed completely it would still be business as usual at the Joneses. Stucke explains that the structure creates a comprehensive thermal envelope with insulated cavity walls and floor and large double-glazed windows providing pleasant daylight to all internal spaces.

Solar underfloor heating

Sun angles were carefully considered during the design, minimising direct summer sun while getting the best from winter sun. Solar thermal systems generate hot water to be used for domestic purposes and also serve as a heat source for the underfloor heating during winter. Evaporative cooling towers provide additional cool air to ventilate the house during summer. A photovoltaic (PV) system generates power that is fed into the Eskom grid, effectively lowering the energy consumption of the house. Low-energy LED light fittings and appliances are used throughout the house. Gas stoves and ovens provide all cooking and heating requirements and reduce electrical consumption. Exposed concrete soffits and masonry internal walls provide high internal thermal mass to stabilise diurnal temperature swings. The high thermal mass also retains the energy used to heat or cool the building for longer.

Water storage consists of 40 000 litres of clean rainwater stored in tanks while all recycled water and collected ground-level rainwater is kept in the storage dam. The dam is designed to have its level vary from dry to wet season as the water is stored and used as required. During the dry season the storage dam’s total capacity is 60 000 litres. The borehole on the property is intended to be used as sparingly as possible, and only used to top up the tanks while waiting for rain to fill the storage systems.

Water wise

House Jones reduces water consumption by harvesting rainwater in two stages: • Roof-level rainwater is collected for non-potable use in the house. • Paving run-off and subsoil drainage is collected directly in the storage dam and used for irrigation. Rainwater is filtered and used for non-potable purposes while council water is filtered separately and delivered to three potable taps in the house. All waste water generated in the house (except kitchen waste) is treated on site in a two-phase anaerobic/aerobic digester system. Clarified water is then fed through a wetland to further purify the water before it’s stored in a dam and used for irrigation.

project focus Green extreme

The Joneses went to green extremes even during the reconstruction of the old house. Construction waste was carefully soft-stripped and all reuseable materials were reclaimed and donated to charity. This included all electrical and sanitary fittings, windows, doors, cupboards, roof coverings and timbers. All masonry was crushed on site and used in three ways: • Over-excavated foundation trenches were backfilled and compacted before casting foundations, for geotechnical reasons. • Surface bed-back filling and levelling was done. • It was also used for paving subsoil, back-filling and levelling. No crushed masonry was carted away – the balance was used to level the sub-divided portion of the site. Extensive preservation and reuse of top soil and existing planting reclaimed paving blocks from the site were reused in the new paving design.

The following environmental management clauses were included in the contract: • Soil had to be protected from contamination during construction while mixing cement and other contaminating products. • No or minimal storm water run-off would leave the site. • Waste generated during construction had to be minimised and sorted on site for recycling. • Substances such as paints, solvents, sealants, adhesives, etc had to be of low toxicity and low VOC (volatile organic compounds). • Water used on site for washing, irrigation, etc had to be minimised through conservation and recycling. Clearly, keeping up with the Joneses’ lifestyle goes far beyond mountain bikes and a jet ski or two. From the first demolition stage and through construction of the new house they have maintained the highest standards of green building.

Vela Building Solutions leads the rollout of ABTs in the construction of community infrastructure There is a strong groundswell of state and public sector demand in South Africa and other countries in southern Africa for alternatives to bricks and mortar in addressing the housing demands of expanding and rapidly urbanising populations as well as the associated community infrastructure – including schools, crèches, clinics, and even offices and retail stores. Vela Building Solutions, a pioneer and lead player in the application of sustainable alternative building technologies (ABTs), has more than doubled its production capacity to cater for existing and anticipated demand, says founder and CEO Brent Harris. At the same time, the Gauteng-based company has established local operations in Mozambique and Namibia and is reinforcing the deep market footholds it has established in Angola, the Democratic Republic of Congo (DRC), and Zambia. In addition, opportunities are being assessed in other countries south of the equator, he adds. “The biggest issue with using traditional bricks and mortar construction methods is that there is too much reliance on the skills of the builder. ABTs, on the other hand, ensure uniformity and more consistency in the final product,” says Harris. The Vela Building Solutions offering in ABTs is fourpronged, namely:

Modular

Vela’s Modular Building Solutions division provides a self-developed modular solid-walled, rapid building method that delivers a high-quality permanent house (or other structure) at relatively low cost – by seamlessly applying the efficiencies of factory production to onsite construction that uses low skills. This not only results in competitive pricing and fasttrack construction, but also counteracts the effects of the shortage of skilled workers, non-availability of building materials in remote areas, and the need for maintaining construction quality.

Vel’ekhaya

A cost-effective and relocatable solid-panel modular housing unit that can be bought “off-the-shelf”, Vel’ekhaya is transported in a flat-pack and is easily erected by no more than four people. It is not only an ideal step-up from sub-standard housing but can also be used as a backyard rental unit, emergency housing or shelter, temporary classroom, contractor camp accommodation, temporary office, and store room.

U-TRUSS

African construction industry set to assist Cummins growth strategy Cummins, a global leader in the manufacture, sales and servicing of diesel engines and related technology, has identiﬁed the African construction industry as a sector that holds enormous potential for growth and expansion in 2013. South Africa is expected to prepare itself for an infrastructure development boom in the short-term future following the October 2012 announcement by President Jacob Zuma that the government is drafting legislation to enable infrastructure development by raising funds for 18 strategic infrastructure projects estimated to be worth more than R4-trillion over a 15-year period. Cummins Africa sales engineer for construction and earthmoving equipment Ettiene Holtzhausen believes this announcement holds considerable prospects for companies at all levels of the South African construction industry and he is conﬁdent Cummins can establish a strong foothold as a preferred supplier in this highly competitive market. “This is welcome news for the South African construction industry, which experienced a highly

challenging year in 2012. Cummins experienced a distinct drop in the sales of new engines during this period when compared to 2011, and I believe this can be attributed to the fact that construction projects in general have been in decline since the last boom in 2010,” he explains. Holtzhausen highlights the fact that the international Cummins Group has a global network of 500 company-owned and independent distributor facilities at more than 5 200 dealer locations in over 190 countries. “This provides local contractors and original equipment manufacturers (OEMs) with the peace of mind that they are being provided with the highest-quality engines that undergo hours of testing in the ﬁeld and in the test cells to ensure reliability and durability to power these large infrastructure projects forward,” he remarks.

advertorial With particular focus on markets north of the border, Holtzhausen points out that new engine sales to the African construction industry rose steadily during the course of 2012 and he is optimistic of further growth throughout 2013 and beyond. “As a result of this continued growth in a rapidly expanding market, Cummins is currently in the process of developing a stronger presence in Africa by establishing dedicated sales and support branches in key regions such as Botswana, Zambia, Namibia and Mozambique,” he adds. According to Holtzhausen, the most popular Cummins engines in the African construction industry are the B-Series and C-Series ranges. “The range of B-Series engines boasts highly reliable, durable in-line fuel pumps that deliver a steady stream of pressurised fuel for strong performance across a wide range of African terrains and operating conditions. C-Series engines have proven themselves to be durable and reliable in some of the most remote locations and harshest working environments in the world. A robust in-line fuel pump delivers more power while making it possible to use lighter-weight fuels such as Jet A and kerosene when diesel fuel is not available. And both series can be fitted with rotary fuel pumps if need be,” he explains. Holtzhausen also notes that all Cummins B-Series and C-Series engines meet Tier II standards as set out by the US government’s Environmental Protection Agency (EPA). “Compliance with EPA specifications ensures that all Cummins engines minimise environmental damage by generating clean power while increasing fuel efficiency and lowering operating costs without affecting the power of the engine. EPA laws are world-class and although the specifications are not a legal requirement in a number of African countries yet, it places local contractors in the perfect position to stay one step ahead of the game by adopting the new technology at an early stage.” In an economic climate where cheap and inferior counterfeit imports entice fleet owners with limited budgets, Holtzhausen stresses the importance of realising that any heavy-duty machinery is only as reliable as the engine that powers it. He therefore advises local contractors to take into account the long-term cost implications of purchasing engines and parts with unrealistically low price tags. “Looks can be deceiving when it comes to critical parts for Cummins engines. Although injectors, for example, may all look similar, a closer inspection will reveal dramatic differences in the design, tolerances, craftsmanship and quality of materials used in Cummins genuine parts, which deliver improved performance and longer life spans between overhauls,” he notes. As a result of the continued influx of engines that are manufactured in Asia and fitted to numerous vehicles and equipment locally, Holtzhausen admits

Cummins has been faced with challenges to keep the supply of genuine parts ﬂowing. “With this in mind, local OEMs have been encouraged to purchase through the authorised Cummins SA channel which provides full product coverage for service, warranty and Cummins genuine parts supply,” he states. Cummins maintains a record of all of the company’s engines entering the country by application and OEM. If a customer has a Cummins engine in an automotive or industrial application, they are given 100% assurance and peace of mind that they will be provided with full support throughout the life cycle of the engine. Cummins also boasts a state of the art facility in the USA, where the company’s entire range of engines are only approved for application after complying with the highest international standards of quality, including ISO 9001 and ISO 14001. For additional customer peace of mind, Cummins recently entered into joint venture agreements with a number of OEMs based in Asia, including the establishment of the Hyundai Cummins Engine Company (HCEC) with Korea-based Hyundai Heavy Industries. The HCEC joint-venture operation will be located in Daegu, South Korea, with engine manufacturing to commence in 2014. The new facility will have the capacity to build more than 50 000 engines per year at full production. HCEC will supply engines spanning the mid-range 5.9-litre to 8.9-litre displacement range for Hyundai excavators, wheel loaders and industrial equipment. The joint-venture engines will power Hyundai equipment in markets with high growth potential not only in Africa, but also Russia, the Middle East and Southeast Asia.

advertorial Cummins vice-president and president for engine business Rich Freeland adds: “The formation of the HCEC joint venture takes Cummins’ working relationship with Hyundai to a much closer level, where we can share our respective expertise and better position both parent companies for growth in markets around the world.” In addition to genuine parts, Cummins also offers a range of reconditioned (ReCon) parts and engines which provide effective alternatives when replacing worn parts, components or complete engines. Cummins Africa sales and marketing director for new and ReCon parts business Andy Pilkington states: “The complete range of Cummins ReCon engines are rebuilt to meet or exceed Cummins specifications at a competitive price, compared to either a new engine or a locally rebuilt engine.” When a ReCon engine is sold to the customer, Pilkington explains that the old engine is returned to the Cummins distributor and sent to one of many Cummins ReCon plants in either the USA, UK or Mexico. There it is stripped down to component form. “Every component is completely cleaned and inspected to first check if it is fit for remanufacture to Cummins specifications. If it doesn’t meet these specifications, a new part is used. One key component of this assessment is that all critical tolerances are inspected using the latest computercontrolled technology to ensure that they meet or exceed Cummins specifications.” Pilkington adds that a team of highly qualified and experienced technicians only build ReCon engines, thus ensuring that once the reconditioning is completed, the customer is effectively provided with a brand-new engine, complete with the same factory warranty as a new engine.

Pilkington notes that the Cummins ReCon strategy keeps waste out of landﬁlls and allows the company to remanufacture reliable products while consuming up to 85% less energy and resources than it takes to produce new products. “One of the biggest differences of doing business with a worldwide company like Cummins is the warranty coverage. The Cummins warranty covers 100% parts and labour, progressive damage, mark-up and consumables. It is backed by the world’s largest network, with more than 5 500 service locations,” he adds. Although optimistic of the future outlook for Cummins in the African construction industry, Holtzhausen admits that the company must still overcome a number of challenges. “The poor performance against the US dollar has proven to be a challenge for numerous African countries and due to the fact that Cummins engines are imported from the USA and Europe, it has resulted in customers purchasing less as the direct cost price of each individual product continues to rise as a direct result of the exchange rate. Looking at 2013, I believe the most growth for Cummins in Africa will be generated from rapidly developing construction industries in Angola, Botswana, Ghana, Morocco, Nigeria, Egypt, Algeria, Zambia and Namibia,” he concludes. Established in 1919 in Indiana, USA, Cummins today employs more than 40 000 people worldwide and has an annual turnover of US $10,8-billion. Cummins South Africa is headquartered in Johannesburg with branches in Alrode, Bloemfontein, Cape Town, Durban and Port Elizabeth.

LED lighting solutions for the hospitality sector slow on the uptake The South African hospitality sector has made significant inroads with regards to its investigation into energy-efficient lighting solutions but has been reasonably slow in implementing these for various reasons. So says François van Tonder, managing director at NTL-Lemnis Africa. “One of the reasons is that bigvolume savings involve large capital investment and complicated projects which need to be coordinated and managed. A more effective approach, however, will be to focus on areas where savings can be easily and quickly achieved while major projects are planned for a later stage,” he adds. Van Tonder says that light emitting diode (LED) technology has evolved to the stage where a simple retrofit of bulbs can be quickly and easily achieved with minimal disruption to commercial operations. Often hotels, restaurants and entertainment venues address LEDs as part of a larger project involving heat pumps, solar heating and other energy-saving initiatives. But this need not be the case. Replacement LEDs can save up to 90% of current energy consumption by simply replacing the incandescent or energy-saving bulb currently in use. For example, 50-Watt down-lighters can be replaced directly with the Pharox range of 6-Watt down-lighters. So by replacing 100 down-lighters one can realise a saving of 4400 Watt.

Addressing challenges

One of the challenges faced by LED suppliers in the past was the recreation of the ambience which hospitality properties want. Current LEDs and warm white lights with colour temperatures between 2200K and 3000K can allow sites to test which LEDs will recreate or enhance the look and feel they are trying to provide. Another challenge is capital outlay. In order to address this, NTL-Lemnis Africa has partnered with various institutions to provide flexible finance options on implementing LED solutions.

NTL-Lemnis is the first LED company in the world to register a carbon reduction project under the Clean Development Mechanism (CDM) governed by the United Nations Framework Convention on Climate Change (UNFCCC). Pharox is the only approved lighting product for the National Greening Programme which aims to offset the carbon emissions generated during the 2010 Soccer World Cup. NTL-Lemnis has developed the Pharox LED range as retrofit replacements for incandescent and compact fluorescent lamp (CFL) bulbs, as well as halogen down-lighters. Compared to an incandescent or halogen lamp, a Pharox LED lamp enables enormous energy savings while displaying none of the drawbacks of CFL bulbs. Pharox LED lamps give off warm white light, don’t contain mercury, don’t flicker and switch on immediately.

Pharox brand of LEDs

The Pharox LED range has a standard fitting for direct replacement in just about all existing fixtures. Due to its long life, they are an ideal retrofit solution for the hospitality sector where a combination of high-quality light and low maintenance is required. Moreover, Pharox lamps have a distinguished and visually pleasing look which makes them suitable for fixtures that leave the lamp visible. Further investigation into high-wattage down-lighters, parking area lighting and floodlighting would further enhance the savings that could be achieved. NTL-Lemnis Africa has successfully installed the Pharox range of LED lamps in various hospitality properties including hotels, game lodges, guesthouses and entertainment venues.

Lighting should be a key global focus when it comes to energy efficiency. It’s common knowledge that traditional bulbs not only consume a great deal of power, but are also environmentally unfriendly in their make-up and production cycles – hence the ongoing focus on new-generation lighting technologies and systems. In South Africa, the free give-away by Eskom of CFL light bulbs has been an attempt to get a grip on the Demand Side Management (DSM) portion of the South African power conundrum. But, despite this advance, the reality is that not all lighting solutions are equal. When it comes to the quality of light produced, the general environmental impact of different bulbs and the cost savings the varying solutions offer, the differences can be dramatic.

carbon emissions reduction project. The firm is also registering the first, and now validated, LED lighting CDM carbon project in South Africa named “LED’s Kick-off”.

“As new players and products emerge at a rapid rate, so the need for technical clarity grows,” says Francois van Tonder, Managing Director at NTL Lemnis Africa, the producer of industry-leading Pharox© LED bulbs. “Companies planning to move to energy efficient lighting really should be putting a far stronger focus on the technical details of various solutions and products.”

“The equation is not just about cost savings, it’s about full participation in the green economy when it comes to things such as carbon credits,” says Van Tonder. “To a lot of architects and business people, carbon credits are something to do with the future. But in fact they have quickly become a business reality. They need to be factored into decision making. We at NTL Lemnis see it as our duty to provide a complete sustainable alternative to traditional lighting; this includes harnessing the benefits of a CDM project.”

Lighting and the Clean Development Mechanism (CDM) NTL Lemnis Africa is the only LED lighting company qualified by the South African Department of Environmental and Tourism Affairs as a certified National Greening company. The qualification comes as a result of Lemnis’ participation in the FIFA 2010 Soccer World Cup

NTL Lemnis clients benefit directly from these accreditations, as they are able to off-set a significant portion of their lighting costs against the carbon credits generated as result of the project.

In addition to broad themes such as carbon credits, van Tonder highlights five significant technical points architects and project managers should bear in mind when addressing lighting installations in new and retrofitted projects.

• Replacement without customer concessions – Pharox LED bulbs are designed to produce the same warm white light (which is the ideal replacement for traditional halogen and incandescent lighting) or cooler white colours (for more commercial or industrial applications) in terms of efficiency and longevity. The key design departure being that the client has the same quality of colour and level of lighting they were used to, but now at vastly reduced energy consumption rates of up to 90%. • Lower maintenance and replacement costs – Pharox LED lights have a lifespan of 35 000 to 80 0000 hours, which reduces lighting maintenance and product replacement costs significantly. • Mercury content – Pharox LED bulbs are the only way to ensure mercury-free lighting. Recent studies indicate that a single fluorescent tube can contaminate in excess of 20 000 litres of ground water. • Recyclable – The best new-generation LED lights are manufactured according to a cradle to cradle philosophy, which means the vast majority of the light and all its constituent parts is recyclable. The recyclable portion of the light should be in excess of 90%. • Pharox LED technology – The light source of the Pharox LED bulb is actually an array of microchips of different colours that combine to generate a specific light spectrum. The globe

runs far cooler than traditional products as it does not rely on heating a filament metal to generate light, and is thus longer lasting and more efficient. “Research, research, research” says Van Tonder. “That’s the only way to make sure that the system you’re using in a project is as cost-effective, efficient and green as the service provider claims. The reality is that one LED solution can be as much as 50% more efficient than another. So professionals owe it to themselves to do their homework, and to take the broadest view possible of each system and the bottom line green benefits it actually offers.” It is not only the corporate sector that should be taking a holistic and longer-term view on expenses on energy efficient technologies, but also the individual customer. The Return on Investment (ROI) of switching to good LED technology will in most cases end up in a breakeven or cash neutral scenario when energy consumption reduction, longevity, carbon credits and numerous other benefits are taken into account. “At NTL Lemnis this is certainly our focus – taking a broad, holistic view ensures that our Pharox lights are able to remain the market leaders,” concludes Van Tonder.

Clean COLORBOND™ ULTRA steel for a super-cool roof Clean COLORBOND™ ULTRA steel, the prepainted AZ200 roofing material manufactured by BlueScope Steel, was recently used in the major rebuilding of the Blue Route Mall. The Blue Route Mall is a popular shopping destination in Cape Town’s southern suburbs. The project manager was BHF de Jager, working closely with main contractor Aveng Grinaker LTA and Louis Karol Architects. In total 58 000m2 of double level shopping area was added, plus a further 29 000m2 of parking in the basement. The new roof covered 30 000m2. The BlueScope Steel product in exclusive colour Amazing White was formed into Ziptech 420 by Hulamin. The roof contract was undertaken by Scheltema. Clean COLORBOND™ ULTRA steel was also formed into Ziptech XT cladding and used as Cladtech F350 panels for eaves and soffits. According to Alan Blair from internationally recognised architectural firm Louis Karol Architects “it was imperative to use a roofing material that was able to meet strict green building standards and the client’s demands in terms of durability and thermal performance. The roof is also designed in such a way to maximise on the natural light flowing into the mall, thereby reducing dependence on artificial lighting.” The pre-painted roofing material was chosen for its energy-efficienct properties – BlueScope Steel’s colour, Amazing White, has a high solar reflective index (SRI) value. SRI is a combination factor of colour, infrared reflectivity and emissivity. “The white colour chosen by the designers of the Blue Route Mall upgrade provides an ideal cool roof. The unique infrared paint system used on all colours of the entire

Clean COLOLRBOND™ steel range incorporates various essential sustainability features such as high reflection of incoming solar radiation, exceptional colour retention, anti-chalking and dirt resistance”, says Wayne Miller, the BlueScope Steel head of operations in Southern Africa. “The same product was used in the construction of the South Africa Container Depot near Cape Town Harbour – the industrial category winner in the Southern African Institute of Steel Construction’s Steel Awards 2010 – and more recently at the Mall of the North in Polokwane”, says Miller. Under harsh climatic conditions, especially within the sensitive 5km coastal zone, Miller advises the following: “Use only premium grades of coated steel such as ZINCALUME® steel and pre-painted steel such as Clean COLORBOND™ steel, all manufactured with a 55% aluminium, 43.5% zinc and 1.5% silicon coating (AZ150 coating), to gain a much longer service life.” This advice is based on years of experience in the aggressive climatic conditions of Southeast Asia, Australia and more than 12 years’ product performance in South Africa. “If you are building in industrial environments where there are aggressive fumes or particulate fallout within a 200m radius or if the location is within 100 to 400m of the sea, we would advise using our Clean COLORBOND™ ULTRA steel. This has an AZ200 coating – in this case coated to a mass of 200 g/m2 over the steel substrate,” explains Miller.

Temperature

Urban Heat Islands and Cool Roofs The term urban heat island (UHI) is used to refer to the fact that cities and urban areas are often significantly warmer than the rural or undeveloped areas that surround them. Urban forestry and cool roofs are two of the most effective ways to reduce the intensity of UHIs. Light-coloured COLORBOND® steel with Thermatech® technology can be used to create cool roofs because it has high solar reflectance and thermal emittance.

The formation of urban heat islands

Urban heat islands are not a new phenomenon. In 1833 chemist and amateur meteorologist Luke Howard presented evidence that the air and surface temperatures in London were often higher than in the surrounding countryside; this is now considered to be the first documented case of an urban heat island (UHI). Today many cities and suburbs record air temperatures warmer than the surrounding natural land cover. The United States Environmental Protection Agency (EPA) reports that on average US cities are up to 5.6°C warmer than the surrounding countryside1. Urban heat islands form when vegetation is replaced with non-reflective, high-mass, waterresistant, impervious surfaces that absorb a high percentage of incoming solar radiation. There are three main drivers of heat island formation: 1 i ncreased absorption and retention of heat due to decreased surface reflectivity 2 r educed evapotranspiration due to decreased vegetation cover 3h eating as a result of human activities. The formation of heat islands is not necessarily uniform

across the city or over time – heat islands can evolve around a single building, across a small section of the city or over the entire city region. Some researchers have also reported that local and regional climate and the topographic features of cities affect the strength and persistence of heat islands. 1. Surface reflectivity: Increased absorption of heat All surfaces reflect a proportion of the energy that arrives from the sun (solar or shortwave radiation). The more reflective a surface is, the less solar energy it absorbs and the cooler it is. Conversely, the less reflective a surface is, the more solar energy it absorbs and the higher its surface temperature will be. Compared to natural land cover, urban environments have lower surface reflectivity, absorb more of the available incoming solar radiation, and are consequently warmer. This is the beginning of the formation of a UHI. The shortwave radiation absorbed by the surface of the Earth is predominantly re-radiated to the atmosphere – and eventually to space – as longwave radiation (see Figure 2). Energy also leaves the surface

by thermal convection and conduction (sensible heat), and when water is evaporated (latent heat). The amount of energy re-radiated from a surface is dependent on the temperature of that surface – the hotter the surface, the more energy it will emit. Because cities are comparatively warmer, they can emit more longwave radiation than the surrounding countryside. Because of its longer wavelength, re-radiated energy can be absorbed by clouds as well as particles in the atmosphere such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and water vapour (H2Ov), i.e. greenhouse gases (GHGs). These particles emit the energy back to the atmosphere and to the surface of the Earth (see Figure 2) and emitted longwave radiation acts to heat both the atmosphere and the surface further. The increases in atmospheric GHG concentrations that have occurred due to human activities – particularly since the industrial revolution – have resulted in an overall warming of the atmosphere (the anthropogenic greenhouse effect). Because activities in urban environments are often major generators of GHGs (such as in exhaust fumes), outgoing longwave radiation from cities is more likely to be absorbed and re-radiated in the atmosphere above cities than longwave radiation emitted from the surface in a less polluted environment. The net result, again, is more potential heating of both the city and atmosphere above it.

3 Anthropogenic heating: Heating as a result of human activities The third factor that causes UHIs is the increase in near-surface temperatures that is a result of human activities – for example, the heat produced from industrial processes, electricity generation and building and traffic heat. The combination of heating at the surface and in the lower atmosphere can create an inversion layer which stops heat and other pollutants dispersing. This enhances the heat island effect and is a cause of smog (ozone) formation at the surface.

2. Reduced evapotranspiration Evapotranspiration is the sum of evaporation and transpiration: essentially the sum of water entering the atmosphere from the surface of the earth. Evaporation accounts for the movement of water to the air from sources such as the soil, forest canopy interception, and bodies of water such as lakes and oceans. Transpiration accounts for the movement of water within a plant, and the subsequent loss of water vapour through the leaves. Evapotranspiration acts to cool the surface because of the loss of latent heat – the energy used during phase change from liquid to gas. Evapotranspiration is generally decreased when vegetation is replaced with a cityscape – there are less transpiring plants, fewer opportunities for interception, and runoff is increased because of the expansion of impervious surfaces. The reduction in evapotranspiration therefore contributes to the formation of a UHI.

Consequences of urban heat islands

In low- and mid-latitude cities such as Sydney, New York and London, increased local temperatures often lead to increases in energy demand for air-conditioning, particularly in the summer. This in turn places a strain on power delivery systems and may result in the need for additional power generation sources. If power is generated using fossil fuels, GHGs and particulate emissions are also increased. Thermal comfort is reduced inside buildings without air-conditioning and outside and there is evidence that heat-stress mortality and illness are higher in cities during the summer months than at other times of the year. High pollution levels – particularly under inversion conditions – can also adversely affect human health. Infants, the elderly and those with respiratory or cardiac complaints are particularly vulnerable. High concentrations of pollutants can also affect the buildings themselves: deposition of acids (such as sulphur and nitrous dioxides) from the atmosphere, and soiling (black carbon deposition), have a corrosive effect on limestone, sandstone and marble structures. Acid deposition can also adversely affect the water quality of nearby lakes and rivers and the animal and plants that live in them. The health of forested ecosystems can also be negatively affected – trees are weakened through leaf damage, nutrient limitation and the uptake of toxins from the soil.

Mitigation of urban heat islands

Increasing surface reflectivity (to reduce the amount of solar energy absorbed and converted to heat), and evapotranspiration (to cool the surface through latent heat loss), are two of the key strategies for reducing the intensity and longevity of UHIs.

technical feature Potential evapotranspiration can be increased by extending vegetated areas and reducing the amount of impervious surfaces. Urban forestry has been found to produce the greatest reduction in surface temperature per unit area, because of the increase in evapotranspiration and the additional shading of buildings and pavements3. Urban forestry includes street-to-trees i.e. curbside planting, and grass-to-trees i.e. open-space planting. Roof-to-grass, i.e. living roofs, also effectively increase evapotranspiration, particularly in areas with limited space at street level. Green roofs do not, however, have as great an impact on energy demand because they afford no additional shading to buildings. Replacing dark surfaces and roofs with light surfaces and cool roofs increases the reflectivity of the city. This is a very effective UHI mitigation strategy because more surface area can be transformed in this way than can be planted. For example, it is estimated that 64% of the surface area of New York City could be redeveloped to incorporate highly reflective surfaces, whereas only 17% of the city’s surface could be planted3. Cool Roofs Cool roofs help reduce the intensity of UHIs as well as maintain thermal comfort and minimise energy demand in buildings. Cool roofs have high solar reflectivity and preferably high thermal emittance. High solar reflectivity means that less energy is absorbed into the roof initially, thereby reducing the amount of energy that can be converted to heat and re-radiated as longwave radiation (see Figure 3). This reduces the heat that can move from the roof to the atmosphere by convection and conduction –

Hot dark roofs – heat the atmosphere (and the home) due to high absorption of solar radiation.

Figure 3 Cool roofs vs traditional dark roofs

the surface temperature of a cool roof can be up to 39°C less than a dark-coloured roof1 – and limits the amount of longwave radiation that can interact with GHGs and heat the atmosphere. High thermal emittance means that any energy that is absorbed into the roof is re-radiated from the building quickly (again increasing thermal comfort and minimising energy demand). There are also financial benefits for building owners. Limiting the quantity of absorbed solar energy and reducing daily temperature fluctuations – which cause repeated contraction and expansion – can extend the life of the roof. BlueScope Steel’s cool roofs The Building Code of Australia (BCA) classifies roof colour based on solar absorptance – the inverse of reflectance – expressed as a ratio between 0 and 1. Solar absorptance values are based on as-new/ unweathered product. A value of 0 indicates that a roof absorbs none of the incoming solar radiation, whereas a value of 1 would mean that a roof absorbs 100% of the incoming radiation. Three classes have been established: solar absorptance of less than 0.35; solar absorptance of between 0.35-0.55; and solar absorptance of more than 0.55 (referred to herein as very light, light and dark respectively). BlueScope Steel produces a range of roof products with low solar absorptance (high reflectance), ≤0.55. Light-coloured COLORBOND® steel – incorporating Thermatech® solar reflectance technology – has higher thermal emittance than ZINCALUME® steel, which is not painted. So a light-coloured COLORBOND® steel roof not only reduces the amount of solar radiation absorbed but is also very effective at re-radiating heat. This means that the building will be cooler overall and cool down quicker when the sun goes down, which helps reduce energy demand. Overall, a light-coloured painted steel roof on a building surrounded by trees – to provide shade and water movement to the atmosphere – is one of the best design scenarios to reduce the intensity and impact of UHIs. In South Africa, architects are beginning to utilise the energy-saving potential of cool/white roofs, using Clean COLORBOND™ Ultra Steel in large commercial development projects such as the South African Container Depot (Milnerton), Mall of the North (Polokwane) and the Blue Route Mall (Tokai).

project focus Investec Bank decided to move from their offices in Durbanâ&#x20AC;&#x2122;s CBD to an office park in a new periurban business centre. A landmark corner site was selected with panoramic views over the Indian Ocean and high visual exposure to major arterials. The brief was to provide premium-grade offices with a sophisticated expression capturing an established corporate image and rendered in high-quality materials. A building that would not only complement the existing Investec portfolio of offices around the country, but also convey the institution as a leading international investment bank. The spectacular ocean and distant views across to the cityscape had a major influence on informing the arrangement of the office space around public

interface and service spaces. An expressed desire for transparency and that all the occupantâ&#x20AC;&#x2122;s experience activity within the building be visible acted as a design driver, being displayed by a dramatic glazed atrium, glass partition office walls and three prismatic cantilevered meeting pods. Sets of escalators convey circulation in the arrival space and generate a legible energy in the heart of the focal space. This office building displays a broad range of sustainability initiatives including raised office floors throughout with displacement air conditioning, an energy fly-wheel system on the air conditioning to retain energy from the exhaust air and reversible heat pumps to capture the by-product energy from

Fritted toughened glass panels, supported on stainless steel spider fittings, attenuate light ingress and act as a sunshade to the atrium and exhibit a sheer faรงade which complements the granite-clad forms of the building to deliver a memorable signature.

Thermal Insulation The new National Building Regulations for Energy Usage in buildings were published in November 2011. The new standard, SANS 10400-XA, has created a huge challenge to the professionals who are responsible for the implementation of the new rules. When the requirements of SANS 204 are properly applied, energy efficiency can be obtained in one of the following manners: • insulating or shading the building fabric • controlling heat flow through the building envelope and glazing • reducing air leakage through building fabric • creating internal air movement for cooling • i mproving efficiency of heating, cooling and hot water systems. SANS 10400-XA includes the application of the National Building Regulations Part X: Environmental sustainability and Part XA: Energy usage in buildings. Much work has already been done around individual energy-saving devices such as energy-efficient light bulbs and solar water heaters. SANS 10400-XA incorporates these existing standards into a holistic overview of the entire construction process, which then serves as a reference to help architects, building construction companies, insulation manufacturers and other stakeholders to ensure that their buildings comply with energy efficiency requirements.

Building envelope requirements

Orientation The building should be compact in plan, with the rooms that are used most and the major areas of glazing placed on the northern side of the building to allow solar heat to penetrate the glazing during the winter months. Floors Where an underfloor heating system is installed, the heating system shall be insulated underneath the slab with insulation that has a minimum R-value of not less than 1,0. External Walls Non-masonry walls shall achieve a minimum total R-value of a) Climatic zones 1 and 6: 2,2 Climatic zones 2,3,4 and 5: 1,9 b) Fenestration Buildings with a fenestration area to net floor area per storey that exceeds 15% shall comply with the requirements for fenestration in accordance with SANS 204. Roof assemblies Roof assembly shall achieve the minimum total R-value specified in the table below for the different climatic zones of South Africa.

From a plastic bottle to a Think Green Insulation Sheet Millions of plastic bottles end up in South Africa’s landfills every year. Finding ways to manufacture useful recycled products from these bottles will not only shrink landfill sites, but will also support the construction industry in finding sustainable building solutions. A.G Ismail is a company that offers an insulation to clients that is manufactured from 100% recycled plastic polyethylene terephthalate (PET) bottles. Their Think Green Insulation is a professional product that can be used in dry-walling insulation and ceilings. This insulation sheet will keep a building cool in the summer and warm in the winter, improving heat regulation and minimising the need for artificial temperature control systems. Creating a Think Green Insulation sheet The most common container in the soft-drink market in South Africa today is the PET bottle. Recognisable as the transparent, rigid container used to package bottled water, carbonated soft drinks (CSDs), sports drinks, water, juice, peanut butter, salad dressings, oil, cosmetics and household cleaners, PET is labelled with the #1 code and is 100% recyclable. Discarded post-consumer PET bottles are collected, baled and delivered to the recycler. In the recycling plant, the bottle tops are removed and the bottles

are inspected and sorted according to colour and material. The sorted bottles are washed and then conveyed to a granulator, where they are reduced to flakes before being screened. These flakes are then washed and dried and conveyed to an extruder where the material is turned into pellets. The finished product takes the form of small clear pellets, which are supplied to end-users for production into a number of everyday household items, including the Think Green Insulation sheets that A.G. Ismail supplies and installs. The demand for recycled products A prevailing demand for polyester fibre continues to provide the most economic end-use for South African recycled PET, and demand currently exceeds supply. In South Africa, Gauteng generates the most PET postconsumer products at 55% of the national total, followed by the Western Cape with 13%. Recycling one ton of plastic bottles saves 1,5 tons of CO2 versus landfill or incineration processes. More than 1,4 billion PET bottles have been recycled in South Africa to date. Think Green Insulation is available in 5 different thicknesses. It has passed all required and regulated tests and is market-approved.

Hitting the roof Metrotile roofs provide peace of mind with safe and eco-friendly cover

Metrotile Woodshake in action as an alternative to thatch.

Woodshake is versatile enough for any thatch re-roof.

In an unpredictable and ever-changing climatic environment, nature can cause severe damage to property – as was seen in the wind-driven fires at the thatched chalets of Sondela Nature Reserve and more recently in the raging fires engulfing thatched residences in St Francis Bay, leaving around 100 families homeless. The recent hailstorms in parts of Gauteng causing millions of rands in damage is further confirmation of the risks properties are exposed to. While hindsight gives 20/20 vision, much of the damage could have been avoided and contained if all the positive attributes of lightweight stone-coated steel roof tiles such as Metrotile’s were known to property owners. Metrotile’s premium steel roofing system goes beyond the durability and performance of traditional roofing materials. Made from highly protective AZ185/ Z300 corrosion-resistant steel, these tiles are ductile and thus ideal for coastal installations while they are also resistant to the damage caused by extreme weather conditions and fire to traditional roofs. This affordable, lightweight stone-coated roof system is ideal for use on new projects and re-roofs, specifically for thatch and old “zinc” roofs, creating an effective weather barrier, removing the high maintenance requirements and shielding the property from fire and hail. Metrotile’s roofing system can also save owners of thatched properties around 30% on their insurance premiums. Because the tiles are far lighter than traditional roofing systems, they don’t require the same heavy (and expensive) roof structure – and being recyclable they are in tune with current sustainability trends. To cope with the strong demand for these eco-friendly roofing systems in the past few years, Metrotile Europe had to double their production capacity. This expansion of capacity allows them to produce over 50 000m2 of premium stone-coated metal roof tiles, providing cover equivalent to over 800 RDP houses per day!

Celebrating their 15th anniversary, Metrotile invited their international distribution partners and top clients from all over the world to join them in Belgium for the Grand Opening of their new plant in Tongeren at the end of November last year. Building on its success all over Europe and in many African countries, Metrotile is now lifting the bar for metal roofing in southern Africa. Metrotile Southern Africa was one of five distribution partners who won an award for their marketing efforts as a newcomer in the Metrotile family, measured against that of their international colleagues . Since its debut in South Africa just over a year ago, Metrotile SA has expanded its range of unique and ecologically conscious roofing products while focusing on superior customer service and sustainability. In their constant search for improvement of the “Metrotile experience”, they were faced with the question why there are so many waterproofing and roof maintenance companies in the market. At the end of the day property owners are the ones who suffer from poor service, therefore Metrotile SA is actively recruiting and training teams of competent installers to ensure their roof installations match the reputation of their premium product. And to underpin their commitment to proper installations, they are also launching a free maintenance plan for all new Metrotile roofs, installed by approved contractors. These initiatives are only some of the reasons why the name Metrotile equals peace of mind and is fast becoming the preferred supplier of eco-friendly roofing systems in the world.

Pro Lok 700: the roofing choice for the future When the South African Container Depot in City Deep, Johannesburg, needed to extend its building, the Pro Lok 700 concealed fixed-roofing system was once again used with excellent results. Roofing erector Cerbon installed the 28 tons of roofing material with ease and no problems. Pro Lok 700 is a vertical clip-in roofing system with a metal clip track and Technyl C216CV30 extruded anchor towers. These anchors were specially designed to accommodate the extreme temperature variances of the Highveld during wintertime. Designed for commercial and industrial use at low roof angles, this product consists of three wide pans with two stiffening ribs each. Pro Lok 700 also has four ribs, each 41mm high. Bidvest, the holding company of the South African Container Depot, wanted a secure building with natural light. The building had to be absolutely watertight, but financially viable to erect. Pro Roof Steel Merchants, the manufacturer of Pro Lok 700, used a mobile mill to roll form on site. This

process enables the rooﬁng erector to utilise long length sheets (up to 50m) in order to minimise the possibility of water entering into the building through the roof. The long length sheets were roll-formed at ground level and then lifted onto the roof where they were installed into the direction of the prevailing winds. This installation method ensures the integrity of the roof during storm conditions. Pro Roof is dedicated to supplying the best in concealed ﬁxed-metal roof sheeting for the South African market.

Sans 10400-xa poses new challenges for the roofing industry The energy efficiency legislation for new buildings, SANS 10400-XA, has been published by the regulator (NRCS). All new buildings will have to comply with the performance parameters, which means that insulation will have to be installed to achieve the stipulated R-values. Words by Dion Marsh The new SANS 10400-XA legislation requires far deeper sections of uncompressed insulation in the roof cavity to achieve the new prescribed R-values. For insulation to perform effectively it needs to be installed in a continuous layer, without compression and with minimal thermal bridging. It is widely accepted that the ideal location for this insulation in the roof space is over the purlin. Over purlin installation avoids the obstructions imposed by trusses, bracing and reticulation systems which invariably would contribute to excessive thermal bridging. The challenge in the roofing industry is the interface between the outer roof covering and the underlying structure when accommodating these deeper depths of insulation. Until recently the roofing industry attempted to create roof cavities with various forms of steel U-spacers. These spacers were only partly successful, were labour-intensive, and still compromised the performance of the outer roof sheeting. The loose U-spacers did not support the longer fasteners which exceeded their design lengths, in turn increasing the risk of failure due to expansion and contraction of the outer roof covering. It is for this reason that most roll-formers of concealed fixed steel roof sheeting will not give a warranty on their product if installed over uncompressed insulation exceeding 50mm in depth.

yield galvanised bars of the ASHGRID SPACER SYSTEM by means of conventional self-drilling fasteners. The ASHGRID SPACER SYSTEM accommodates all forms of pierced and concealed fixed steel roof sheeting manufactured in South Africa.

Thermal and acoustic performance

Although the new SANS 10400-XA legislation only places emphasis on energy efficiency it is critical that roofs also perform well acoustically. There would be no point in having an energy-efficient roof on a school which amplified the drumming sound of rain and other external sources of noise. The ASHGRID SPACER SYSTEM allows the professional design team to combine configurations of rigid and cumulus insulation without compression to achieve a roof that is aesthetically pleasing while offering high thermal and acoustic performance.

The ashgrid spacer system has all the answers

It is critical that the interface between the roof system and the insulation should be considered during the design phase. The ASHGRID SPACER SYSTEM is designed to suit all SANS 10400-XA legislation building types and climate zones, including cyclonic regions. It raises the roof sheet above the purlin, creating a defined space for the insulation material to recover to its optimum design thickness and insulation value. The ASHGRID SPACER SYSTEM is an engineered system which transfers the loads of the outer roof covering evenly into the underlying roof structure. The outer roof covering is simply installed to the high

project focus The Trust Centre was originally an old beer hall. Structures were added from time to time as the need arose. When the beer hall burnt down and went up for sale, a few friends established the Greater Stellenbosch Development Trust (GSDT), bought Erf 27 with the help of donors, and rebuilt the buildings as a Trust Centre in 2002. By 2008 the building was in bad need of repair. Additional space was needed for various new facilities. The trustees, with the help of architects, planners, educationalists and members of the community, then created a long-term plan for Erf 27. The aim was to design a Trust Centre that would accommodate various uses and needs of the community that might arise in the future and also make the best possible use of the available land. The design process involved demolishing certain old components of the building and structuring the design into a more clearly organised spatial whole. Separate buildings, such as a day-care centre, an afterschool care centre, a multi-functional hall, an administrative and adult education block, a restaurant and an amphitheatre are linked through outdoor spaces, courtyards and walkways, giving it the feel of a small village.

This exciting collection of spaces of different scales achieves a range of strongly identifiable internal and external spaces, situated on an exciting topography. The building fits well into its surrounding township context but also adds a positively reinforcing atmosphere to the surrounding area.

Community spirit

Local labour, contractors and artisans participated in work and decision-making on the building. The handcrafted scrap-metal gates, for example, which are one of the features of the project, were made by local artisans. It was important to local residents of Khayamandi that bright colours be used. Neutral backdrops allowed for key spaces to be highlighted with bright colours. Vibrant red is used for the roofs of common areas while a quiet blue-grey defines spaces of learning and concentration. Green walls

embrace places of gathering and a yellow wall stimulates creative playing. The zinc cladding of the new section, which rises out of the ground and sprawls over and towards the older buildings, is symbolic of the spirit of the community rising up and growing into something greater. The corrugated sheeting and randomly placed windows are also reflective of the surrounding township context. As a whole the combination of old and new and of different textures represents the vibrancy of Khayamandi. The open, flowing design of the new restaurant component welcomes people in from the street and provides uninterrupted views through to the amphitheatre and the majestic Stellenbosch Mountains on the northern side. It creates a space where all people can come together and open up new conversations. Since its original completion in 2010, KR2 architects

have been asked to design further extensions to AmaZink Eatery due to the great amount of interest and visitors to the centre. The iKhaya Trust Centre has now become a significant new space for the benefit of people in Khayamandi and Stellenbosch. The Greater Stellenbosch Development Trust, the owner of the centre, and key tenants and partners AmaZink and Vision K continuously push the initiatives of the centre and have introduced a number of events and activities at the centre to benefit the community. These include The Annual Kayamandi Arts and Cultural Festival hosted by the Vusisizwe Community Theatre Project, a non-profit organisation with offices at the centre.

The InZink amphitheatre at the iKhaya Trust Centre is a popular venue for a variety of cultural activities and is used for screening sports events, films, live music and opera and monthly poetry sessions. KR2 and the iKhaya Trust Centre in Kayamandi, Stellenbosch, received a prestigious Merit Award from the Cape Institute for Architecture in October 2011. The Cape Institute for Architects noted that â&#x20AC;&#x153;materials and detailing are modest yet highly skilful. Careful selective elaboration teaches that considered detailing can make gutters and downpipes beautiful. The architecture is restrained yet sophisticated. The architects are commended for a job well done and are encouraged to enrich the lives of South Africans in this way.â&#x20AC;?

Advancing into commercial carpet space A new entrant has entered the commercial space in the carpeting industry, with the aim of offering flexibility, style and quality to the specification market. Derived from the French word for ‘advance’, Avance Carpets boasts locally manufactured product and is ready to tackle the commercial carpet space. Despite challenges in the property market, not unique to South Africa, Avance Carpets believes the commercial property market is showing healthy potential, with many opportunities. The company aims to become a strong player in this space. It’s a tough market for small businesses in South Africa, however Avance already has a competitive advantage premised on the backing of 50 years of innovation in the carpeting industry. This is combined with investment in technology that ensures a range of product is made available and enables flexibility to meets clients’ requirements for small, medium and large commercial projects. Entering the commercial space is backed by positive yet cautious sentiment expressed in the market. This includes the Broll Annual Market Report – a review of the global, continental and local retail, industrial and office sectors – released earlier this year. Malcolm Horne, CEO of Broll Property, states that despite challenges there are several indicators of an increasingly vibrant local property sector. “In addition, growing interest in Africa as a destination for many multinational businesses is resulting in a significant uptick in the demand for quality retail and office space in several countries to the north,” Home adds. In fact, the Investment Property DataBank (IPD) Global Cities Report states that Johannesburg has avoided being hit by the global property crash as its offices, shops and warehouses outperformed those in every other global city outside of South Africa over the past decade. The report states that commercial property is a key measure of economic vitality, since strong retail, leisure and industrial performance encourages investors such as pension funds to buy up buildings to earn income through rental income and capital value increases. “Capital value appreciation in Johannesburg has hit 6.8% over the 10 years to 2011, compared to 2.9% for New York, 1.8% for London and -0.1% for Munich over the same period. Like Johannesburg, Sydney, Melbourne and Seoul remain (relatively) untainted by European contagion, and investor appetite has been growing in these locations,”

Advanced unique offerings

The plan to establish a new brand providing products for the commercial property sector came to the fore a year ago, with the management of Avance officially launching the company in August 2012, following compliance with all necessary legislation.

Avance Carpets provides colour customisation for a range of carpet tile and broadloom options for projects over 500m2. He adds that, based on international trends and updates in the market space, ranges are available in both carpet tile and broadloom formats, which are vibrant, trend-conscious and available in a wider offering. “The niche service of allowing clients to choose their own colours and designs is possible, as the company believes it has the flexibility as a small manufacturer to undertake such a service”. The strong drive to invest in technology is validated by the acquisition of a tile manufacturing plant in Harrismith which enables the company to meet the capability and capacity requirements of the unique service it offers clients in the commercial space.

The team

Avance is backed by a strong team with significant experience in the carpet industry. Karl-Heinz Lutze, innovation manager, has been trained in traditional and modern carpet manufacturing techniques. Equipped with the latest software and with modern machinery at his disposal, he is able to work on new designs in various synthetic and natural fibres. There are also three consultants based in Durban, Johannesburg and Cape Town who will be working to grow the Avance brand and drive business growth. Cape Town consultant Hecéle Campbell has eight years’ experience in the carpet industry. In Durban, clients will deal with Janice Steyn, who has been working with the building industry for seven years. Nickey Cloete, based in Johannesburg, has 16 years of carpeting experience to her cap.

The future

For now, employees at Avance are focused on driving a strong marketing campaign to create awareness and promote the brand. The company confidently forecasts a project portfolio that will gain momentum in 2013. “As a proudly South African business, we hope to contribute [in line with business growth] in time to employment creation. “As a small business that is looking to survive the challenging market for new companies, we believe that despite the backing of 50 years of experience, we need to establish a strong brand, ethos and service offering in South Africa.”

Modular timber eco home designs Marc Lüdi, owner of Swissline Design and master carpenter from Switzerland, has extensive experience in Europe with the modular concept of building homes or businesses with eco-friendly timbers. He noticed a gap in the market in South Africa which prompted Swissline to start the manufacture of these modules. By using eco-friendly construction timber and raw materials such as Siberian larch timber for wall cladding and European pine (Spruce) which is grown vastly and sustainably in controlled forests in Europe. These modular homes are quick to assemble, sustainable and affordable but in keeping with a more modern appeal compared to the typical wooden home. The desire for clients not to have imposing building work on site continuously for long periods of time and not wanting on-site mess during the building phase has become increasingly relevant in the building of homes in South Africa. Who wouldn’t want a holiday house erected in a maximum of two weeks without hassle? The fact that these modules can be erected on site without destroying any environment is a further benefit. Also, the client can choose all their fittings and fixtures beforehand and have them installed before delivery to avoid numerous contractors on site, obviously making it more cost-efficient. The modular designs are very interchangeable and additions can be done in future according to the client’s budget or special requirements. The materials Swissline Design use are of the highest quality, from the roof to sliding doors and decking.

Exposed timber roof trusses

Swissline Design, through experience and expertise, are leaders in the manufacture, assembly and installation of virtually any shape roof trusses. We import our timbers such as Spruce directly from

a reputable and top-notch supplier in Germany, supplying us with the best-quality construction timber from sustainably controlled forests. Thanks to wood finger joints, trusses can be manufactured in virtually any shape, size or length in Spruce. There is a growing trend to use exposed roof trusses due to their aesthetic appeal and double-volume capability.

Renew, recycle, re-use

Wood is the only 100% renewable, recyclable, reusable and biodegradable resource we have, making the stewardship of wood products an invaluable step in conserving resources. As a modern-day building material, wood delivers exceptional possibilities. The potential for form and engineering is limitless and one of the greatest benefits is that wood is the most environmentally friendly and sustainable building material in the world. 3.4 billion cubic meters of timber is grown annually in Germany alone, thus 31% of the country is producing spruce without harm to the environment. An obvious beneficial reason to use timber is that it is the only building material that is grown from the ground up with very little chemical manipulation and therefore has a small carbon footprint. A fact that proves this point is that more than 25 tonnes of greenhouse gases could be saved if timber products were used instead of the common alternatives when building a home. As a natural building material wood proves itself for its good characteristics such as ease of manufacture, weight-carrying capacity, natural look and natural climate control abilities.

THE FUTURE OF WOODEN WINDOWS AND DOORS

Evolved to Perfection Wooden window and door manufacturer Swartland is launching a South African first that will revolutionise the building industry: pre-finished wooden windows and doors. Wooden windows and doors add warmth and elegance to any home. Current window installation methods can’t guarantee a perfect result every time, because of the varying industry skill levels. Additionaly, once purchased, windows and doors can stand around until the builders are ready to install them. Even once installed, until they are adequately glazed and sealed, exposure to the elements can damage the raw timber. With Ready-2-Fit windows and doors from Swartland, this problem is a thing of the past by offering both a solution with a professional finish and glazing ready for installation. What is the Ready-2-Fit range? It’s a range of wooden windows and doors that are sealed during the manufacturing stage. Glass is then installed before they leave the Swartland factory, so when they arrive on site, they are ready to be installed, with no further labour required to seal and glaze them. This not only saves the builder and homeowner time and money, but it also ensures that the windows and doors are protected against any exposure to the elements. The overall building quality is therefore increased with significant time and ultimate money saving. Ready-2-Fit windows and doors will be available in the Cape Culture and Winsters Collections.

About being pre-sealed Increasing their ability to withstand the elements, the wooden frames are sealed with Swartland’s new high-quality Maxicare water-based sealant. With very low VOC emissions, it’s an environmentally friendly option. It boasts a number of other benefits – it is UV-resistant, non-flammable and leadfree and will protect the wood from the damaging effects of extreme temperatures, humidity, cold, rain and sunlight for years to come. It is also stain-resistant, waterrepellent and durable. Darker colours such as Teak and Imbuia contain heat reflective pigments, which results in a lower surface temperature of the wood and reduces movement. Furthermore, it contains antifungal agents to protect the wood against fungus, and especially dry rot.

How to order the Ready-2-Fit windows and doors Swartland’s pre-sealed, pre-glazed options are available for all its Cape Culture and Winsters products. They can be ordered through all leading building merchants. When ordering, be sure to specify one of the Maxicare colours below. IMBUIA

Sanding is so last year with Wash n’ Wipe A major advantage of the water-based Maxicare sealant is that it makes these products easy to maintain. Instead of sanding, simply Wash ‘n Wipe your timber windows and doors to restore them to their original beauty. All you need to do is inspect your windows and doors before the onset off summer and winter and apply the specially formulated Wash n’ Wipe Maintenance and Touch-up Kit. No sanding is required. The pack comes complete with the Cleaning Agent, Protective Emulsion, Protective Glaze and a sponge, and is available from top building merchants nationwide.

Effortless 3-step maintenance procedure Step 1: First clean the casement using a wet and lint-free cloth. If necessary, a mild cleaning agent can be added to the water. Step 2: Apply the Cleaning Agent to the window frame surface. Allow it to work for a few minutes and then remove, using the enclosed sponge and lots of water. Then let it dry. Step 3: To protect the surface and preserve the original colour of the wood, you can maintain the surface once or twice a year. After Step 2 is complete Simply spray the Protective Emulsion evenly on to the Sponge and Wipe surface evenly . Allow to dry and polish the surface with a clean cloth. Touching up: Repair small scratches and hairline cracks with ease (max 2cm in diameter). Roughen area briefly and apply Protective Glaze.

All Swartland windows come pre-glazed with standard 4 mm glass or 6.38 mm Safety Glass, in accordance with SANS 10137. Double-glazing and Low-E glass is available on request, depending on the application and level of thermal insulation and acoustic performance required. In cold weather Low-E glass reduces the amount of heat loss by reflecting it back inside.

In warm weather Low-E glass reflects the sun’s energy and reduces heat gain in the home.

Mechanical properties Swartland is currently testing all its windows with Safiera (South African Window Energy Registration Council) – a division of AAAMSA. To comply with the SANS 613 (Fenestration Products) mechanical performance criteria, the windows are tested for deflection, structural strength, water resistance, air tightness and operating

forces. The result is that Swartland’s Ready-2-Fit windows will have unique mechanical property values, from A1 – A6, assigned to them. Sub-frame system coming soon Swartland is about to launch an innovative sub-frame system. Made from PVC-U, these cavity closers will make fitting their windows and doors simple and precise, especially when installed by accredited installers. The Sub-frame System offers the Architect & Builder with a fast effective installation method that will ensure superior building quality.

Saves Money Not only does one save time and money by not having to seal and glaze on site, every square metre of cavity closer should also save you around 10 bricks.

SA coatings sector training centre set to open mid-year The new and long-awaited SA Paint Manufacturing Association (SAPMA) Centre of Excellence training centre is set to open around May or June this year.

Above: An exterior view of the new SAPMA Centre of Excellence training facility in Springs. Above right: The SAPITI training management team (from left): training administrator Mandy Linossi, national training manager Toni Stella (seated), and national training co-ordinator Tina Taylor.

The Centre of Excellence will operate from the old BIFSA Training Centre in Springs following a revamp and modification of the premises as well as accreditation granted to the SAPMA training programmes by the Chemical Industries Education and Training Authority (CHIETA). The Centre will be able to increase SAPMA’s capacity for the training of paint applicators from 50 to 500, says Mandy Linossi, administrator of SAPMA’s training arm, the SA Paint Industry Training Institute (SAPITI). She says SAPITI is currently finalising recruitment of training staff for the Centre of Excellence. A South African doyen in coatings training, Toni Stella, was recently appointed as SAPITI national training manager and Tina Taylor as national training co-ordinator. Further appointments will follow shortly. Deryck Spence, executive director of SAPMA, says the association has been inundated with calls from the coatings sector and allied industries to send staff to attend the SAPITI training or establish their own training programmes at the Centre of Excellence. “The opening of the training facility has been particularly

welcomed by painting contractors who will now, for the first time, be able to send staff to a five-day fulltime, intensive training course involving both practice and theory, followed by SAPITI ‘on-the-job’ monitoring.” Spence adds, “Training is vitally needed in the coatings sector – not only from a technical and production point of view but also from an application standpoint. About 80% of all painting and application problems arise from inferior surface preparation and the new Consumer Protection Act’s regulations hold a minefield of potential problems for companies using untrained staff.” “Fortunately government has now at last empowered the coatings sector so we can train workers at our new Centre of Excellence to boost the national economy and create badly needed jobs,” Spence concludes. SAPITI has – despite the previous lack of accreditation – trained over 7 000 employees in the coatings industry since 1987. SAPMA’s quest for government accreditation, which spawned the Centre of Excellence, has stretched over a period of more than a decade and is set to come to fruition soon.

advertorial Cool Powder Coatings

2013 will see the launch of our low solar absorption range of architectural powders. This unique range of powders reflects the solar infra-red radiation, preventing transmission and convection of heat. This means: • l ess heat transferred through window frames, reducing the need for cooling • l ess heat radiated into the atmosphere, reducing heat island effect. The low solar absorption range achieves this by: • i nnovative coating pigments that result in lower surface temperatures, even for dark colours. • u nlike traditional coatings, reflecting a large part of the invisible near infra red radiation (NIR). AkzoNobel’s Cool Powder Coatings reflect up to 45% of the total incident radiant energy from the sun.

Approved applicators

Currently there are eight Interpon-approved applicators nationally that are also SABS or Qualicoat approved. Project guarantees are available only through AkzoNobel’s approved applicators network, to ensure quality and consistency.

AkzoNobel technicians make regular visits to approve applicators to provide support, as well as to conduct audits. Only those applicators whose coating and testing meets the required standards are granted approved applicator status.

Versus Paint Specialists We are here to help you make a better choice in wall coatings Versus Paint Specialists offer an environmentally friendly alternative to normal paints. They have formulated wall coatings that considerably decrease the amount of pollution released into the immediate environment and the environment as a whole. Indoor air is three times more polluted than outdoor air and, according to the Environmental Protection Agency (EPA), is considered to be one of the top ﬁve hazards to human health. Paints and ﬁnishes are among the leading causes of this pollution. “Ideally, you want to use paints that meet better health criteria,” says a Versus Paint Specialists spokesperson. “This means looking out for low-volatile organic compounds (VOCs), low biocides and natural pigment paints.”

Versus products are environmentally friendly as they contain less than 25 grams per litre of VOCs, use nontoxic pigments, are water-based and have minimal biocide content. “Many paints contain VOCs, which refers to a class of chemicals that evaporate readily at room temperature. When these VOCs give off gas, a process that can last for weeks or years depending on the type of paint, they may cause a variety of health problems like nausea, dizziness, irritation of the eyes and respiratory tract, heart, lung, or kidney damage, and even cancer,” says the Versus spokesperson. “Versus produces low VOC coatings. These paints are durable, cost-effective and less harmful to humans and environmental health than conventional paints.”

Dulux: Paint going Green About Dulux South Africa

A household name in South Africa, Dulux was owned by South African chemicals giant AECI until 2007 when it was acquired by British chemicals group ICI. AkzoNobel acquired ICI at the beginning of 2008, bringing Dulux under the same umbrella as well-known global coatings brands such as Sikkens, International and Eka. With its local headquarters in Alrode, Gauteng, Dulux has a major manufacturing facility at Umbogintwini in KwaZulu-Natal and a regional distribution office in Cape Town. Dulux currently locally manufactures or imports around 1,000 product lines for supply to its South African market and export markets in various African countries. Dulux recently confirmed its reputation as a household name in decorative paints when it was selected for the second year running as the winner of the TGI Iconic Brands paint category and positioned among the top 14 overall brands of South Africa. Dulux South Africa is currently headed up by CEO Johann Smidt.

About AkzoNobel

Headquartered in Amsterdam, AkzoNobel is a Global Fortune 500 company, the largest global paint and coatings company worldwide, and a major producer of specialty chemicals. Our portfolio includes world-renowned brands such as Dulux, Sikkens, Dulux Trade, Rockgrip, Fix It, International and Eka. Our iconic brands are manufactured and distributed from operations in more than 80 countries and across 5 continents. Driven by our vision for future-perfect products, we offer practical solutions with minimum environmental impact. With scale comes responsibility. And as the largest player in the paint and coatings industry, we understand our role in meeting the needs of the present without compromising the ability of future generations to meet theirs.

Our approach to sustainability

“Sustainability is core to everything we do. We are committed to systematically improving our performance across the entire sustainability spectrum. We have been striving to be a more sustainable business for some time, and have made real progress, but the more we understand about the issues, the greater we see the need for more radical action. It is our ambition to reduce the whole-life ecological footprint of the decorating process and to contribute to more sustainable home, work and leisure environments, as well as minimise the

environmental impacts of our own operations” says Frank Wagner, Marketing Manager for Trade. ‘Step Towards Greener’ explains this approach.

Light & Space

Dulux Trade Light & Space is an innovative water-based paint that harnesses advanced LumiTec technology to reflect significant amounts of light back into the room and therefore save energy by requiring less artificial lighting.

Light & Space Case Study

Light & Space has been used in the restoration project of the Oyster Box in Umhlanga Durban. “Light & Space was used on all the ceilings, cornices and the administration wing. I was very impressed with this product as it really creates more light. The white is very Brilliant White. I highly recommend this product to any architects looking at opening up a room and creating a feeling of space.” Anton de Kock, M2K Architects, Cape Town

Dulux Trade Environmental Wash System

This unique system allows customers to wash out their brushes, rollers and other painting tools with minimal impact on the environment. Waterbased paints are converted into clean water and a small, manageable amount of solid waste. The water can be re-used and the disposal of the solid waste has been rated as a low-risk activity by The UK Environment Agency. The Dulux Trade Environmental Wash System is also used in the Dulux laboratories and training centre.

Environmental Wash System Case study

The environmental wash system was used on the Durban Moses Mabhida stadium. Smith & Winfield Painting Contractors painted the stadium. “The Dulux Trade Environmental Wash System has really added value to our contract in painting the New Moses Mabhida Stadium as it has allowed us to comply with Best Practice not only for the main contractor but also for ourselves. Once we had installed the unit and were trained, we were able to put into practice the great benefits of this Environmentally Friendly Water-based Paint Wash-Up System. We felt that we were actively involved in trying to reduce hazardous waste from entering our water systems on this enormous site. We would recommend this Envirowash unit as it greatly added to the sustainability factor of this project, something which all manufacturers and contractors are striving towards.” Nigel Murray-Rogers from Smith & Winfield Painting Contractors, Durban

Highveld landscape is continued on the stepped, grass-planted roofs. Access from the existing facility is afforded along an axis that extends from the existing conference venue all the way to the new extension. A new courtyard space is created inbetween the existing buildings and the new facility, where a water fountain enlivens and cools the transitional space. Essentially this space holds the built masses together as a central datum point, with access to adjacent new spaces along a covered outside stoep area. Visible from afar, a high screen to the east announces the

Building depths do not exceed 10m, a measure that is advantageous in terms of environmental control â&#x20AC;&#x201C; both relating to natural light and the reduction of air conditioning. While the flat, planted concrete roof has thermal advantages, it steps to allow light to filter into spaces. Rain water is harvested for internal use. Materials and finishes had to match and complement the existing

building, resulting in a low-maintenance face brick finish. A structural grid of 5 x 5m is used for the new building. This allows for an ideal building width to accommodate environmental control, structural efficiency and spatial flexibility. Passive environmental design strategies are applied in the design for the new facility. The layout, insulation, window size, orientation, shape and proportions have all been optimised in order to use the least possible external energy for thermal comfort.

Lighting

The section of the new building was carefully considered to allow reflective light through clerestory openings. Incoming light falls on reflective surfaces to distribute light evenly. Ceilings are placed at angles to help distribute and guide light to maximum benefit while also providing acoustic buffering. The placement of workstations was carefully aligned with the lighting strategy whilst allowing flexibility. In addition, efficient lights and occupancy/ light level switching is applied to save energy consumption. Screens play a major role in controlling the

environment, especially for the diffusion of direct sunlight along horizontal strip ribbon windows.

Solar PV generation

Most strategies are above target maximum demand but have a huge secondary benefit of reduced consumption. In order to ensure the total consumption reduction of 88.5MWh/annum, a further grid-tie PV generator of 12.6kWp produces approximately 22 517 kWh/annum. The photovoltaic array is approximately 100m2. This system provides an additional 3% of the total Vulindlela complex energy consumption.

project focus Air conditioning

Air conditioning is the single biggest load and consumer in office buildings. The strategy for the new extension is four-fold: Reduction of need by passive design and fresh pre-cooled/heated air supply, reduced load through energy-efficient equipment, under-floor heating through a solar heater and lastly solar cooling with an air ventilation system. In line with the energy strategy of the building, a chiller is installed on the concrete roof over the store area. This feeds cold air via the light shaft to the central spaces in the office and hot air is introduced by means of air pipes feeding hot air from the ground level.

Sustainable landscaping

Existing trees are preserved as far as possible. New trees are all indigenous and landscaping water-wise. In addition, as part of the environmental strategy, it was decided that a planted roof will harvest water. Water is channelled into a storm water system to

a lower level sump in the courtyard. A solar pump distributes water to tanks on a level higher than the roof where it can be gravity-fed for landscaping and grey water purposes.

Solar warm water

The conventional electrical geyser is replaced with a solar hot water system.

Generator switching

The standby generator is equipped with a new panel. This allows the system to switch on the standby generator once a critical demand level has been reached. The effect of all the above systems is that a 10% saving for the whole Vulindlela Complex is afforded. Despite the integrated approach to systems, the language of the new addition is in no way dictated by systems per se. Architectural design strategies around proportioning, horizontality and simplicity are therefore not compromised as a result.

Avoiding mine closures Moves are afoot to manage the execution of controversial Section 54 of the Health and Safety Act which some quarries allege is misused on occasion by authorities to shut down mining operations for reasons other than the legislation intended. Promulgated in 1996, the Act was designed to give the Department of Minerals and Energy (DME) inspectorate the instruments required to enforce health and safety legislation and to shut down operations if deemed necessary. In a number of instances, however, quarries contend that the legislation was unfairly invoked for reasons unrelated to health and safety and was even used as a bullying tactic by some unscrupulous officials. Following some disagreement with the Mine Inspectorate it was decided to establish a committee to investigate the matter and to ensure future execution of Section 54 is done in accordance with the Act and its guidelines.

Moving the bar

The Aggregate and Sand Producers Association of Southern Africa (Aspasa), which sits on the newly established committee, has also taken additional progressive steps towards ensuring that its members do not fall foul of the legislation. In future all Aspasa member companies will be made fully aware of all legislation relevant to the Act and its annual Implementing Safety Health Education (ISHE) audits will be intrinsically linked to the guidelines. “Sand and aggregate quarries have been closed in the past, some due to bad practices and others as a result of officials’ poor interpretation of the Act and guidelines. The establishment of the committee is a move in the right direction and we feel that our moves to link our ISHE audits with Section 54 legislation is yet another step towards a safer industry,” says Aspasa director Nico Pienaar. “Aspasa is in total support of addressing unsafe practices on mines and we have been undertaking ISHE audits of member quarries for the past 15 years. We fully support the DME’s attempts to enforce health and safety, but do not support any kind of bullying tactics used by officials,” states Pienaar.

Early warning

He adds that by further linking ISHE audits to Section 54 requirements members will have forewarning of any transgressions and audit findings will immediately be made available to quarry management as well as

owners to give them an opportunity to take corrective measures and get their houses in order. Millions of rands are lost due to unnecessary mine closures. In the sand and aggregate industries these can have devastating knock-on effects for critical infrastructure development as well as the building industry, which relies heavily on the localised supply of sand and aggregate. “By taking every step possible to ensure our quarries remain open and operational at all times we feel we are not only ensuring the future sustainability of our industry, but also ensuring critical construction projects remain on schedule,” says Pienaar. He also stresses that health and safety is a critical focus for quarry owners and role-players.

Non-members involved in the mining of sand and aggregates should contact Aspasa for more information about joining the association. Call Aspasa on Tel: 011 791 3327 Fax: 086 647 8034 E-mail: nico@aspasa.co.za

Illegal mining hurts everybody Selling sand and aggregates from illegal mining operations is a criminal offence that deserves to be punished just like any other serious economic crime. So says Nico Pienaar of the Aggregate and Sand Producers Association of Southern Africa (Aspasa), who is urging authorities to prosecute owners and operators of illegal mines and quarries to the full extent of the law. Despite clearly defined laws, acts and regulations that govern the industry, illegal mining is still commonplace and the will to prosecute transgressors has been nonexistent. “Illegal mining and quarrying operations have a massively unfair advantage over legal operators in the industry. They don’t pay royalties, tax or make any other statutory contributions to government or towards the sustainability of the industry. Nor do they need to observe safety, health, environment and quality legislation which means they can expose their employees to inhumane working conditions, as well as cause untold damage to the environment without fear of retribution,” Pienaar adds. Amazingly, Pienaar says, the practice of illegal mining is not only confined to dubious cloak and dagger syndicates, but is also being practised by certain municipalities and even some large-scale construction companies. “Whether these operators feel that they are above the law or simply claiming to be ignorant remains to be seen. Either way they are committing a serious crime that can no longer be ignored,” he says.

Change is coming

But Pienaar expects that this is about to change following two constitutional court rulings recently that finally clarifies the basic requirements to operate a mine or quarry in South Africa. In both cases – against Swartland Municipality and Maccsand – mining rights were granted prior to all zoning or environmental requirements being satisfied. As a result, protracted legal battles ensued which tested the roles of local,

regional and national government departments in allowing mining operations to go ahead. In both cases the court ruled that mining operations may only go ahead with necessary permission from local government departments regarding land use and the correct zoning of land according to requirements. In addition, regional and national environmental legislation needs to be obtained and observed for the duration of the lifespan of the mine. “In summary, it means that all legal requirements need to be met on a local, regional and national level and that the granting of a mineral rights permit does not mean that all other legal requirements are superseded. As an association we are heartened by the verdicts and call on all illegal operators to comply with the laws of the land or face possible criminal prosecution,” states Pienaar.

Blowing the whistle

“Aspasa has called on its members to blow the whistle on illegal mines and quarries regardless of the size or who owns the operation. With the direct involvement of the Department of Mineral Resources, as well as relevant law enforcement agencies, we hope to formalise the industry and eradicate illegal mines,” says Pienaar. “For the sake of law enforcers and mine operators alike we have even compiled an easy-to-read, comprehensive document that outlines legal requirements for operating a mine. In this way anyone can determine if an operation is legal or not. “If we are able to stop illegal operations we will be in a better position to ensure sustainable practices are upheld, both in terms of the economic development of the industry as well as ensuring the environment is protected,” concludes Pienaar.

Environmentally friendlier quarries Operators of pits and quarries belonging to the Aggregate and Sand Producers Association of Southern Africa (Aspasa) are continuing to clean up their acts with everimproving scores being reflected in the association’s environmental auditing program. Yet independent auditor Alan Cluett of Alan Cluett Consulting says most operations are easily complying with requirements in practice but need to keep better records in future to prove conformance to authorities as well as to outline implementation of their environmental management plans. Aspasa director Nico Pienaar says the association is pleased with the overall results of the audit and urges member companies to administer environmental matters more carefully to avoid falling foul of

legislation. While members do pay careful attention to compliance, he agrees they need to keep better documentary records in order to be able to provide proof of compliance if needed. While better administration is required across all areas, some of the main concerns include poorly written letters of appointment for responsible managers. The majority of these viewed by the auditor covered only an appointment in terms of Section 3.1 (a) of the Mine Health and Safety Act.

130

128-131_ASPASA.indd 130

2/5/13 6:25 PM

advertorial At best, reference in the letter of appointment to the managers’ environmental management responsibilities were contained in a reference to the National Environmental Management Act, the National Water Act and in some rare instances the “Minerals Act”. “These letters need to be amended to include the manager’s responsibility for environmental management at the operation with speciﬁc reference to the Mineral and Petroleum Resources Development Act (as opposed to the Minerals Act) and must pay reference to the management of the requirements of the Approved Environmental Management Programme for the operation. After all, it is a document that allows for the issue (and withdrawal) of the operation’s mining license,” stresses Pienaar.

Legal registers

Legal registers are another area of concern as these are often found to be complicated compilations of some applicable legislation interspersed with volumes of irrelevant legislation not applicable to the operation or the industry. In many instances these “registers” were found to be simply an index of South African legislation. “What is of particular concern is that some consultants to our operations have completed a ‘compliance audit’ against the register and simply inserted the word ‘Complies’ adjacent to headings

such as The Constitution or NEMA or MPRDA,” cautions Pienaar. “This is misleading and absolutely unprofessional. Members should remember that the purpose of the register is to be a tool to assist the manager in the achievement of legal compliance, which in all cases is an objective environmental policy and provides protection from having licenses suspended or withdrawn, signiﬁcant ﬁnes for responsible persons, a prison sentence, or both,” Pienaar warns.

Valuable exercise

Results from the previous year’s audits showed that nearly 100 operations were assessed by the association’s auditor and that audited scores improved based on Aspasa members’ sustainable and environmentally friendly mining practices. The association’s “About Face” audits are designed to assist members to comply with all relevant legislation, as well as Aspasa’s own environmental guidelines. Furthermore, the audits benchmark operations against all other participating quarries to provide a snapshot of the entire industry’s performance against environmental regulations and guidelines. In addition, information gathered may be used by the Department of Mineral Affairs as an additional means of assessing applications for future mining license decisions.

priority

he National Home Builders Registration Council’s (NHBRC) mandate is guided by the Housing Consumers Measures Act, 1998 (Act No. 95 of 1988) (as amended) whose objectives, inter alia, are to regulate the home building industry, provide protection to housing consumers in respect of the failure of home builders to comply with their obligations in terms of the Act, to provide warranty cover against defined structural defects in new homes, to establish and promote ethical, quality and technical standards in the home building industry and in so doing protect the interests of housing consumers.

By law all new home builds have to be registered with the NHBRC irrespective of the value of the planned house development.

Need to be registered In terms of the Act, any person in the business of building homes must register with the NHBRC. Registration with the NHBRC provides a licence and a right to build homes. To qualify as a registered NHBRC home builder, applicants are assessed on their technical, construction and financial capability. By law all new home builds have to be registered with the NHBRC irrespective of the value of the planned house development. This ensures that the home build has warranty cover against defined defects and that through the comprehensive NHBRC inspection process, the construction is structurally sound and meets NHBRC technical standards. In instances where builders do not meet their obligations (as stipulated by the Act) and where poor workmanship has been uncovered, the NHBRC has a complaint and remedial procedure to resolve such cases.

Home consumer protected The NHBRC may suspend a home builder’s registration and/ or right to enrol homes where it has information that the builder

has failed to rectify reported defects by either the consumer or the NHBRC inspector and/or where the NHBRC considers that immediate intervention is in the best interest of the home consumer.

Subsidy housing At the onset, the mandate of the NHBRC did not cover the low cost housing (subsidy) sector. Unregulated, a number of builds in this sector did not meet technical and industry standards. In some instances the product delivered was of a substandard technical quality, inferior materials were used and substandard building practices were employed. Currently the majority of the houses that are to be demolished or are undergoing major repair were built pre 2002. In February 2002 the Honourable Minister of Housing announced that the NHBRC Warranty Scheme will apply in the housing subsidy sector. In the subsidy sector, the NHBRC has initiated remedial works of housing subsidy failures. The organisation enrols new housing builds, conducts

A winning partnership Improving the lives of the South African people through the provision of quality homes is a collective responsibility. The NHBRC is in continuous engagement and consultation with provincial governments to sensitize them on the risks of utilizing unregistered builders. And partnerships with the private sector remains crucial to ensure that rules and regulations are followed, and standards in the building industry is maintained.

Increased awareness critical to the future of alternative building technologies Alternative building technologies (ABTs) are considered by some to be the future of construction in South Africa and the key to delivering housing to the homeless. However, the lack of awareness of this exciting technology in the country has kept it largely under wraps. Sasol ChemCity, Sasol’s business innovation incubator, has been at the forefront of developing businesses with ABTs in South Africa for more than ﬁve years. They believe more should be done to educate existing and future engineers, architects and contractors about the beneﬁts and uses of ABTs. Serenta Ramraj, a specialist business analyst at Sasol ChemCity, reiterates that South Africa needs to increase awareness in the country regarding ABTs. “Alternative building technologies have been around for years but it is only now that we have seen some movement in the market with regard to the acceptance of ABTs. We’ve started to see some of the entrepreneurs we have assisted secure projects,” she states.

What are alternative building technologies?

ABTs are types of building technologies which conserve or renew natural resources in the construction industry while remaining environmentally friendly. Popular ABTs include structural insulated panels, insulated concrete forms, radiant wall systems, timber frames, cob, stabilised mud blocks, straw bales, logs, adobe, rammed earth, plastic forms and earthships (houses built with recycled materials such as tyres). Due to the wide range of ABTs available in South Africa, there is no set way in which ABTs are commonly used by local contractors and engineers. “Once the South African market experiences the beneﬁts of these technologies, I believe the market will grow signiﬁcantly,” adds Ramraj. In 2010 Vela completed 1 200 affordable housing units for mineworkers in North West Province. The company used steel trusses in roof construction instead of conventional materials and currently has projects underway in Mozambique and Namibia.

More education opportunities are needed

Sasol ChemCity has attempted to spur awareness through educating engineers and contractors. “It is imperative to include modules related to ABTs at

Serenta Ramraj

universities and technikons. This will enable the ABT industry to become fully established,” explains Ramraj. In 2012, Sasol ChemCity prototyped an ABT programme. They took 13 students from the University of Johannesburg (UJ) and trained them in the various ABTs available. “With this programme we brought together all the right technical information of the various ABTs in use so that architects would be equipped to design houses or large-scale developments using these technologies. The students had to study the handbook and go and develop a few proposals,” says Ramraj. Due to the success of the training programme, Sasol ChemCity believes it has planted the seed for the use of ABTs in future architects. Through various projects, more and more contractors are being empowered to utilise the technology. “So the next time there is a similar contract, there are skilled contractors available who are capable of building houses or whatever else is required using ABTs,” adds Ramraj. Sasol ChemCity encourages other South African organisations to work with and fund development programmes on ABTs that can eventually lead to the establishment of businesses, create jobs and help address the current housing backlog faced by the nation.

Local government starting to see the potential of ABTs

Sasol ChemCity believes ABTs won’t replace conventional building methods or be a threat to the prosperity of current construction and building material companies. “We know there will always be demand from the corporate and private sector for conventional building techniques,” says Ramraj. “With the changes in the building regulations, which is believed will become more stringent over the next few years, companies in the construction industry need to consider the use of ABTs and the only way that’s going to happen is when they understand the technology. At the same time, we need to make sure we have businesses that can deliver on that, because if a construction company says ‘Build me 50 houses’ we need to have businesses that can deliver. ChemCity’s value-add in this space is to establish and grow such businesses,” she adds.

ABTs are not more expensive than conventional techniques

Sasol Chemcity – an incubator of ABT innovation

The Western Cape has embraced ABTs in an effort to provide sufficient housing for the homeless in the province. “The Western Cape is definitely introducing ABTs into their strategy. We are reaching the point where government is buying into ABTs but we still need to see more of it. However, this is not just from the government – we need to see more from the industry as a whole. One of the major hurdles to bringing these technologies to market is funding,” notes Ramraj. Late last year President Jacob Zuma called for a prompt solution to the housing needs of mining communities. This could accelerate the roll-out of ABTs in the human settlements arena of community infrastructure in the country.

The elimination of long labour hours on construction sites has made it relatively cheaper for contractors and engineers who use ABTs. “The speed of the technologies as well the need for lower-skilled labour makes development projects core feasible. Some of our entrepreneurs have secured large contracts for this reason. From the examples we have seen through our entrepreneurs, it is definitely cheaper to build with ABTs than conventional methods and allows the end user to enjoy a comfortable living space,” says Ramraj. ABTs won’t replace conventional building techniques

Last year Sasol ChemCity handed over newly built classrooms to the Department of Education at the Thistle Grove Combined School in Kinross, Mpumalanga. To meet the exponential growth in student numbers quickly, a new technology using fine ash to create a foamed cement mixture developed by Sasol ChemCity and Tower Technologies was used to build eight new classrooms for the school. The walls and roof of an 85km2 ash building take five days to assemble, making this a highly efficient and cost-effective building material. It has also been approved by the South African Bureau of Standards (SABS). Fly ash is an excellent extender for cement and gypsum is a good building material Sasol ChemCity not only used this opportunity to

help the local community but also to pilot the ash technology as a demonstration of alternative building materials that will help address the housing backlog and job creation opportunities in various communities. “Taking this innovation from idea to market has been particularly rewarding. By supporting the development of this technology, Sasol is showing its ongoing commitment to reducing its environmental footprint. A number of entrepreneurs and private institutions are additionally starting to explore the affordable housing space, identifying it as a market which is ripe with potential,” says Sasol ChemCity managing director Bridgitte Backman.

Extravaganza – an ABT success story

Martin Paulsen formed Extravaganza in 2004 after a research and fact-finding mission overseas. He observed that the pace of technology in the local building industry was not in touch with the technology and methodologies employed overseas. The company then started exploring more efficient methods of construction where the utilisation of bricks had almost become obsolete. “We started with the horizontal insulated concrete form (ICF) system and later progressed to the vertical ICF system known as the ThermoForm system (TF). This system reduced the installation time and increased efficiency,” explains Paulsen. ICF is a system of formwork for concrete that stays in place as permanent walls, floors and roofs. The forms are interlocking modular units that are dry-stacked (without mortar) and filled with concrete. The forms lock together somewhat like Lego bricks and serve to create a form for the structural walls or floors of a building. ICF construction is becoming increasingly commonplace for both low-rise commercial and residential construction as more stringent energy-

efficient and natural disaster resistant building codes are adopted. Through the system and the growth in demand, the company currently employs 60 full-time contractors and created jobs for 350 people. “Currently we are in the process of completing five projects valued in excess of R15 million. The growth can be seen in the number of new projects the company has. We have two additional projects in Pretoria, a 50-unit project in Lanseria, a frail-care centre and a multipurpose centre in Johannesburg. We also have eight units in Swaziland and Cederburg,” states Paulsen. Extravaganza acquired the rights from an Americanbased company to produce the panels, tracks and rails locally. It has also commissioned two plants to produce the material. One plant focuses on the rails and the second produces panels, corners and the tracks from aluminium. Presently a few entrepreneurs who purchase their building materials are being trained but this focus will shift once the plant is up and running.

Be water wise with Cobra The new water-wise shower range from Cobra combines performance with style.

Cobra Watertech has introduced a new range of contemporary styled overhead rain showers and hand-held showers which combine optimum watersaving efficiencies with superior performance. A key innovation in all the new products is a 9-litre per minute flow restrictor. Compared to conventional showerheads, which typically use between 15 and 20 litres of water a minute, Cobra’s new range ensures water and energy savings without compromising on water delivery or spray patterns. The showers deliver a gentle spray of water, similar to raindrops, providing an ecofriendly option with exceptional design. For larger shower spaces, Cobra has introduced a range of brass overhead showers in various shapes and sizes, including round (350mm and 300mm), square (250mm and 350mm) and oval (300mm x 200mm). The 160mm diameter overhead rain shower is ideal for standard-sized shower spaces and all designs are ultra-slim for a modern, contemporary look and feel. All have a ball joint connector and ½-inch BSP female inlet. Cobra’s new offering also includes the budgetfriendly Liana range of square or round chrome-plated polymer overhead rain showers, which also have the water-saving 9-litre flow restrictor and easy-to-clean anti-lime nipples. A range of smaller shower heads and hand showers with an on-trend grey face and anti-lime nipples and Cobra’s revolutionary 9 litres per minute flow restrictor completes the new range.

This category also includes the multifunction Alto hand shower and 120mm diameter shower head, designed for consumers wanting a hydrotherapy experience. The water spray functions are classic, massage, aerated and a combination of classic and massage and classic and aerated. Cobra’s new range is the answer to consumer demand for stylish water-wise showerheads and hand showers across all budget ranges, shower sizes and showering preferences. For example, the Exilis hand shower (product code 007-EXILIS1) has a round face with a classic spray pattern while the Pluvia (code 007PL) hand shower has a modern square face with a classic spray. There are also two linear hand showers featuring modern, sleek lines – the lightweight 007TN which is well suited to Cobra’s popular Tapno range and the 007-LE, which complements the Leading Edge range. For consumers wanting a multifunction hand shower, Cobra’s latest range offers several different designs, including the new Cumulus hand shower which has a classic spray option, a pulsating option and a classic and pulsating combination. New hand shower rails, 002/4LE and 002/5CL, have also been released. These innovative products complement Cobra’s existing shower collection and further cement its reputation as South Africa’s leading manufacturer of high-performance quality tapware and accessories.

Cobra’s future-forward new kitchen mixers Due to the overwhelming popularity of its existing Flex Supreme kitchen sink mixer with flexible hand spray and increasing consumer demand for other similar products, Cobra has introduced two new cutting-edge kitchen mixers – the Erie and the Huron, the latter of which also features the popular retractable hand spray.

The new mixers (ER-971 and HR-971 respectively) are right on trend with current international mixer designs and marry the very latest in form and function to deliver two outstanding kitchen mixers that are as chic as they are sophisticated. The mixers cut elegant figures in any kitchen setting with their sweeping, arched swivel spouts and elongated single-lever handles. Both are manufactured from robust dezincification-resistant (DZR) brass and finished off in sleek, top-quality chrome. DZR brass is a copper alloy with more than 60% copper content, which is much higher than the vast majority of plumbing fittings currently found in the market. This composition, together with the extra grainrefining processes employed during manufacture, makes Cobra DZR brass corrosion-resistant and eliminates the risk of growth of certain pathogens such as Legionella (Legionnaire’s disease). Another benefit of DZR brass is that the bodies of the mixers are superstrong and durable, promising years of hassle-free service. The Huron features a 1.5m flexible, retractable hose that allows the hand spray to be pulled into

the desired position during use to concentrate water flow exactly where it’s needed and conveniently retract to its original position once done. This feature is becoming increasingly sought after in the hardworking modern kitchen where ease of use when it comes to washing fruit and vegetables and rinsing oversized crockery, pots and chopping boards has become a priority. The original Cobra kitchen mixer with retractable hand spray – the Flex Supreme (FX100) – features a standard swivel outlet and large decorative, chromeplated spring-mounted hand spray that lends an almost industrial edge to contemporary kitchens. As single-lever mixers, both the Huron and the Erie have been designed for maximum efficiency in the kitchen. The lever allows for easy operation, including selecting either hot or cold water or mixing it to the preferred temperature as well as selecting the desired water flow. The two new mixers form part of Cobra’s accelerated product development programme which aims to continually bring to market pioneering new products that meet the ever-changing needs of today’s consumers.

Cobra heat pumps raise temperatures at Jackal Creek Demand for Cobra Watertech’s hot water heat pumps for the second phase of the residential development at Jackal Creek Golf Estate has surpassed expectations.

Jackal Creek in Northriding, Johannesburg offers young executives a unique lifestyle experience which blends modern living with premier golf course living. Wayne Anderson of Cobra Watertech attributes the massive demand at the estate to the growing awareness about the benefits of heat pump technology, and more specifically awareness around Cobra’s offerings, which have several unique features. “These innovations, combined with Cobra Watertech’s reputation for professional technical advice and after-sales service, have given us a clear competitive advantage,” he says. The unique features of Cobra heat pumps include: • a manual override switch that can be activated in the event of a lighting strike or power surge • a 2kW geyser element which allows for electrical back-up in the event of equipment failure • a weekly anti-bacterial cycle which prevents the spread of Legionnaires’ disease, a serious and sometimes fatal form of pneumonia • a thermostatic diverter valve that only allows hot water to be sent back into the geyser, preventing cold water circulating through the hot water pipes when opening a hot tap. “The Cobra heat pump is also smaller and more compact than others on the market, which allows for

a very neat and unobtrusive installation,” Anderson adds. “Heat pumps are easy to install and regulate and provide a reliable source of hot water while complementing the modern, urban-chic lifestyle offered at Jackal Creek. “The demand for heat pumps at Jackal Creek mirrors the national trend for Cobra machines, where sales are on a significant upward path,” he adds. “Heat pump technology is clearly becoming a first choice when it comes to energy-efficient hot water, especially when the products are of high quality and backed by professional service.” Cobra heat pumps are designed in South Africa for optimal performance in local conditions. They use three times less electricity than conventional electrical geysers to generate the same amount of heat, which translates into savings of up to 62% on geyser electricity bills.

Solar control

is one of South Africa’s highest priority, when designing a new building or refurbishing an existing one.

Aluglass Bautech has recently completed a specially designed “Butterfly Blind” system for Absa Head Office in Johannesburg, integrating it into the building management system. With this system, the blinds are fully automated and no user is required to operate and control the blinds.

CMY

The material used is produced by Verosol Fabrics B.V. and Aluglass Bautech are the sole distributors for this in southern Africa. 875 sq.m of Verosol EnviroScreen fabric were transformed into “Butterflies”. EnviroScreen is a highly reflective, robust, transparent, metallised fabric which provides visual and thermal comfort. It is woven in a screen-like construction, but with a clear textile appearance, suitable for roller blinds. With its high reflectivity, these blinds can lower the heating and cooling costs substantially, resulting in a reduction of CO2 emissions and therefore minimising the greenhouse effect.

Furthermore, EnviroScreen is truly a green product, in that it is formaldehyde and PVC-free and the fabrics are produced in compliance with ISO 14001, the international environmental standard, as well as being Öko-Tex and Greenguard certified – which means it will contribute significantly to obtaining points in green building rating tools. The metallised fabrics of Verosol are made of Trevira CS or 100% polyester and are vacuum-bonded with aluminium on the reverse side which doesn’t allow light through, it has excellent reflection properties, it can be applied in very thin layers, it leaves pores open, shading properties are colour independent and it has an excellent colour rendering.

Becoming an industry-leading chairman A guide to selecting ergonomic office chairs Despite good intentions, those responsible for selecting task seating still tend to rely on the familiar criteria of chair aesthetics, price and a brief superficial “test-drive” that does not adequately serve anyone. A first step towards understanding how chairs should function is to ask what happens when people sit for long periods of time.

So how does one go about unpacking the jargon inherently existent within the task seating environment? This article provides a step-by-step how-to guide for deciding on one of the most important aspects of work space design without compromising on either aesthetics or functionality. Adjustability for ergonomic chairs has long been understood to be a prerequisite to accommodate the 90th percentile of users and therefore alleviate injury and risk. In a recent study one manufacturer found that nearly two-thirds of workers in an office made no adjustments to their chairs, even though they knew they could. In another study, less than 2% of the subjects in a laboratory setting were able to identify the purpose of the back tension adjustment knob on a variety of chairs. When a chair isn’t adjusted properly, it can create health problems, as people will adjust their bodies to fit the chair instead of the other way around. Today’s chairs have simply become too complex to operate and the end result is that the vast majority of high-performance office chair adjustments are not used correctly – if at all. This conundrum has led to new design ideas which provide all the correct ergonomic support without the menagerie of manual adjustments that are not understood by the average chair user.

Seating as a dynamic activity The very basic criteria of seat depth, seat height, lumbar height and arm rest height adjustment are understood as must-haves, but the race by manufacturers to produce chairs with more and more adjustability has had the opposite effect they set out to achieve. Irrefutable data collected conﬁrms that billions are being lost annually in medical claims, lawsuits and productivity, all due to repetitive use of ofﬁce equipment combined with ineffective equipment.

Pain and injuries occur when muscles become fatigued as they work at maintaining posture. These can also occur if a posture is retained for a length of time without movement. Sitting should be a dynamic activity and therefore the ofﬁce task chair also needs to be dynamic to support the user’s many macro and micro movements throughout the day. But supporting the user is not sufﬁcient anymore. The new revolution in chairs must support the user in the context of working, while he or she is doing different tasks such as reading documents, viewing the monitor, writing by hand or keying on the keyboard.

The Basics

Industry response

Some manufacturers have responded by providing weight-recognition technology that dynamically adjusts backrest resistance to perfectly support each user. Some adjustments, such as chair height, remain the responsibility of the user, but others are best accomplished through automatic mechanisms in order to avoid injury and restriction of movement. Locks and manual recline tension devices fall into the “restriction of movement” category and should be avoided. Superior ergonomic chairs on the market have automatic and dynamic recline adjustments that accommodate both the 45kg woman and the 150kg man, thus allowing spontaneous movement and continuous support for users when they recline. Locking mechanisms have become obsolete. Dynamic headrest support, synchronous armrests attached to the back and not the seat and better cushion support have all been developed to allow the user to perform the multiple tasks needed with maximum comfort through supported movement.

How do you decide?

Knowledge of the different features of chair construction is important in understanding the implications of adjustability and ultimately the choice of ofﬁce chair. Armrests that are connected to the seat, for instance, may cause shoulder extension during recline, while armrests connected to the backrest will move with the body when the user reclines and provide continuous support. Adjustable seat pans for shorter individuals together with a full range of the features described below will allow you to make an informed choice. Faced with extensive human factors research and dozens of ofﬁce chairs on the market, today’s designers and facility managers have the daunting task of selecting the “right” chair out of a sometimes formidable choice of features and an equally vast choice among reputable manufacturers. The table on the right lists the basic ergonomic minimums, features to avoid and if you prefer to look at the Rolls Royce features, a list of ultimates!

1. Adjustable seat height Must allow for a healthy knee angle of at least 90 degrees with feet ﬁrmly planted on the ﬂoor. 2. Capability to recline Supported recline is critical for optimal comfort and minimal stress on the intervertebral discs. 3. Adjustable lumbar support Lumbar requirements vary greatly among individuals, so adjustable lumbar support is vitally important in reducing back stress. 4. Adjustable armrests This reduces muscle loading and helps accommodate a variety of tasks. 5. Arm supports that connect to the backrest Armrests must move with the user and therefore must not be attached to the seat pan. 6. Adjustable seat pan Especially pertinent to shorter users, this feature will allow optimum contact with the back support.

High-Performance Features for maximum ergonomic beneﬁt

1. Dynamic weight-sensitive recline Sufﬁciently tensioned to enable spontaneous recline and encourage regular, natural movement. 2. Dynamic lumbar support Automatically adjusts to the unique needs of each individual. 3. Synchronously adjustable armrests To prevent possible discomfort from uneven positioning. 4. Gel seat cushions Displace weight and reduce contact stress. 5. Dynamic headrest Offers added support in reclined positions to reduce upper-body muscle loading.

Things to Avoid

1. Manual recline tension These are seldom used, cumbersome and generally leave the chair incorrectly adjusted, resulting in vulnerable work postures. 2. Recline locks or limiters Restricting movement through locks and limiters is a no-no. Users should be able to move freely in their task chair. 3. Mesh seating surfaces Mesh does not distribute weight as well as contoured foam or gel cushions unless a tripanel mesh is utilised to disperse the user’s back weight, thereby avoiding point load pressure.

Technical Conservation Services for the Built Environment...

When engaging with the inherent challenges of historical sandstone structures, decorative bronzes, terrazzo, iron, marble, ceramic mosaics, granite or traditional mortars, the prevailing scarcity of traditional artisan’s skills, and a wide-spread lack of specialized conservation proficiency, can meaningfully jeopardize the success, integrity or the aesthetic results of such a project. Founded in 1993, The S.A. Institute for Objects Conservation fields the expertise to train, consult, analyse and generate fundamentally appropriate treatment specifications, on the one hand, and the experience to act as specialized sub-contractor on the other - undertaking technical conservation treatments through its field unit, The Heritage Conservation Group. On sandstone, conservation services can be deployed to consolidate granulating stone, to stabilize laminar exfoliation, to re-instate lost portions, to provide breathable, mineral-based weather shielding, algaecidal treatments, to remove paint layers and/or black sulfite staining, to repair rust jacking and oxide stains, and similar.

150_The Heritage Conservation Group.indd 150

Outdoor bronzes typically require the stabilization of deleterious chlorides, the maintenance of protective, microcrystalline coats, the casting and replacement of missing portions, hot patination treatments, and so forth. In turn, other metals such as iron (forged or cast), lead (monumental lettering and elsewhere) or brass, each have unique requirements. Marble objects and surfaces may invite specialized vortex cleaning, or chemical poultices to remove sulﬁte or oxide stains, algeacidal treatment, polishing and waxing, or the sculpting and replacement of missing portions. In the case of granite, both laminar exfoliation and iron oxide discolouration are common. Grafﬁti may also be present, grouting may have been lost or repairs may be needed to damaged portions. Historic brick and mortars (hydraulic or otherwise) cold stone, mosaics and similar ceramics, encaustic surfaces, terrazzo and many such round out the rich range of architectural components that invites the expertise of conservators...
