The new Discovery global headquarters in Sandton Central has become the largest new build project to receive a 5 Star Green Star rating by the Green Building Council South Africa (GBCSA) to date.
Developed in a joint venture by two of South Africa’s leading property companies, Growthpoint Properties Limited and Zenprop Property Holdings, the iconic new 112,000sqm resource-efficient, cost-effective and environmentally-innovative Discovery head office is the largest single-phase commercial office development in Africa.
Growthpoint Properties Office Division Director, Rudolf Pienaar, comments: “We are thrilled with the 5 Star Green Star certification achieved for this development, especially considering its scale and complexity. The new Discovery head office is now among the most environmentally sustainable and efficient buildings in South Africa. Green building plays a key role in providing spaces in which businesses can thrive. We are incredibly proud to be part of the creation of the new global headquarters for Discovery in a building that is both spectacular and sustainable.”
Zenprop Property Holdings CEO, James Tannenberger, says: “This is a significant milestone for Zenprop, especially considering our long history of delivering sustainable and environmentally friendly buildings across all sectors of the property market. Zenprop has been involved with developing Green Star buildings since the commercial rating tool was first launched in South Africa in 2008, so we are extremely satisfied with what the development team as a whole has been able to achieve on a project of this magnitude and profile.”
GBCSA Executive Director: Certifications, Manfred Braune, points out: “It is the largest new building certified as Green Star to date in South Africa, which makes it an incredible achievement. A 5 Star Green Star rating for a building of this size would have been a challenge to achieve, and we congratulate the entire team involved in this remarkable project. The combination of low-tech and hi-tech is outstanding, ensuring the perfect marriage of load reduction through passive features with technology that ensures optimal efficiency.”
Aurecon is responsible for overseeing the delivery of the developers’ and Discovery’s green intent for the building. Their role has been to ensure it has been designed and constructed with the highest sustainability credentials to demonstrate leadership in the transformation of the South African real estate industry.
Features of the new building which have contributed to the rating include energy optimisation through the advanced design features of its envelope and building services. High-efficiency air conditioning that leverages an outside air economy cycle and indoor air CO2 monitoring. Added to this is low-energy lighting, occupant control and daylight optimisation, as well as the building’s standout high-performance double-glazed curtain wall.
The building is wrapped around a series of sunlit atria that plug into a central concourse. The design of the atria and skylights result in an abundance of natural light without compromising occupants’ comfort and energy performance. Grey and rainwater systems, efficient sanitary fittings, efficient irrigation system and water-wise landscaping contribute to the building’s optimal water performance.
Yovka Raytcheva-Schaap, the Aurecon associate for environmentally sustainable design consulting and project management for the project, points out that, most notably, the Discovery building creates an environment that is centred on occupants’ health and well-being.
Raytcheva-Schaap reports: “The design provides for an ample amount of fresh air, thermal comfort, daylight and connection to the exterior. A fully equipped gym, running track, yoga decks and multipurpose courts are set in the indigenously landscaped roof and encourage an active lifestyle, in line with the Discovery Vitality ethos.”
Aurecon’s Martin Smith adds that the expansive ground floor of the building accommodates Discovery’s retail partners, client services, walk-in centre, staff restaurants and coffee shops, offering an energising experience to both visitors and staff alike.
Smith says: “Upper floor plates, designed for activity-based working, enhance staff collaboration, enjoyment and business efficiency.”
Located on the corner of Rivonia Road and Katherine Street, diagonally opposite Sandton City and one block from the Sandton Gautrain Station, the building comprises three linked office towers which consist of a ground floor, eight office floors and a roof level, which holds Discovery’s sports facilities. It will also offer nine basements with over 5,000 parking bays.
Discovery is expected to take occupation of the property, which is owned by Growthpoint (55%) and Zenprop (45%), towards the end of this year.
Coveted Green Star rating awarded ahead of World Environment Day
Pretoria, 30 May 2016 – The extension of Menlyn Park Shopping Centre in Pretoria has been awarded a 4-star Green Star Retail Design rating by the Green Building Council of South Africa (GBCSA) for the substantial effort undertaken to develop their first building phase, on environmentally friendly design and construction principles. This forms part of the R2 billion redevelopment of the centre, which began in 2014. Due for completion in November this year, the shopping centre will become the largest centre in Africa, with over 500 shops and a trading area of 170 000m2 on offer.
Significant undertakings were implemented to achieve the rating for this phase of the development. Amongst others, use of post-consumer recycled reinforcing steel, ordinary cement in concrete was reduced by 30% through substitution with fly ash; more than 70 % of waste was repurposed; and cyclists are given dedicated parking bays and showers to encourage cycle use rather than emission-heavy alternatives. Potable water consumption in the phased section was also reduced by approximately 70% in comparison to a conventional building of this type.
“Using GBCSA’s Green Star Retail Center V1 rating tool, the extension of the centre was awarded its design rating, based on an independent assessment. This is a significant achievement for the South African retail sector as it opens the way for other centers to follow suit,” says Yovka Raytcheva-Schaap, Associate in the Buildings Unit of Aurecon South Africa. Similar to the Green Star office rating system, the retail center rating tool assesses the environmental performance of the building in eight categories, including management, indoor environment quality, energy, transport, water, materials, land-use ecology and emissions. The retail sector, however, has been lagging in the application of the Green Star tool for rating of projects in comparison to the office buildings sector.
“Given the nature and the size of the project, the certification process was time and detail intensive, which entailed us working closely with the GBCSA on a number of aspects to attain the targeted points in the various categories,” says Yovka Raytcheva-Schaap.
The design of the reconfigured centre includes facilities for alternative transport, preferential parking for fuel-efficient vehicles, and integration into the region’s mass public-transport system. “We wanted to reward our customers and tenants for using alternative transport,” says Marius Muller, CEO of Pareto Limited, owner of Menlyn Park Shopping Centre. “For example, we provided parking bays for scooters or motorbikes close to mall entrances to incentivise people to be part of our low-carbon-emission philosophy.”
The use of building materials that did not have a negative impact on the environment was vital to keep within the prescribed GBCSA guidelines. “We went to great lengths to source building materials in close proximity to the site,” says Neil Graham, project manager and CEO of Origin Project Management. “Great effort was made to source all material locally, which helped in lowering our CO2 and other harmful emissions from transporting the materials.” Timber had to be from environmentally responsible forests and reinforcing steel used in the project has high recycled content.
Use and disposal of waste was another key issue. “It was essential that waste from pre-construction and construction was either reused or recycled,” explains Graham. “We made mulch from wood offcuts, for example, while surplus building materials, such as bricks, were ground down to be used for landscaping or fill.”
Efficient water use involved several strategies. “The municipal water consumption had to be limited” says Raytcheva-Schaap. “And so we implemented a number of initiatives to optimise the water performance of the centre, of which the most notable are rain water harvesting system with extensive capacity and water wise landscaping. In addition, low flow sanitary fittings and metering of the major water uses for continuous monitoring contribute to reduction of municipal water use.
Other important aspects of an environmentally friendly building are access to daylight, connection to the external environment and air quality. “Many people don’t realise how instrumental fresh air is to your health and wellbeing,” says Raytcheva-Schaap. “We exceeded the minimum regulatory fresh air requirements set out by the South African Bureau of Standards (SABS) by 150%, ensuring optimal indoor environment quality which safeguards against any indoor air pollution.”
Ample access to daylight is made possible throughout the extension via the use of glass and skylights, creating a comfortable and health-wise building. In addition, paints, sealants, and adhesives with low or no volatile organic compounds (VOC) were selected in order to enhance the indoor environment quality.
Energy consumption had to be reduced by approximately 50% when compared to a reference building with design properties as stipulated in SANS204, which would also contribute to lower greenhouse-gas emissions. “We installed an energy-efficient heating, ventilating and air-conditioning [HVAC] system,” says Aurecon mechanical engineer Brandon Huddle. “The chilled water air-handling units run on a 100% full outside air economy cycle when the conditions are favourable and have CO2 monitoring for demand controlled outdoor air, which results in a massive reduction in energy usage by the building. Large fans and chilled water pumps make use of variable speed drives which allows only the optimum quantity of air and water to be delivered in order to meet minimum building demands, which reduces unnecessary motor energy consumption. Thermostatically controlled variable air volume dampers in turn deliver only the necessary quantity of air required by the shop based on the heat load which prevents over supply of air into the shops.”
Menlyn Park runs all proficient lights on occupancy and time controls, which are monitored through an integrated building management system, ensuring energy levels are checked regularly for any incongruities.
“We’ve made a commitment to reduce, reuse, recycle and rethink waste,” says Muller, “and this requires that at Menlyn Park we move away from traditional solutions that focus on waste after it has been generated, to a greener approach that looks at the prevention of waste, as well as minimising waste as a by-product of production.” To this end, a waste and recycling management plan (WRMP) was put in place at the shopping centre, to manage the collection, storage, treatment and disposal of all waste. The end goal is to recycle 57% of waste generated, which will ultimately result in diverting up to 80% of waste produced away from landfill.
“This project took the work of many dedicated people, and we are elated to finally see all our hard work and many hours of planning acknowledged by this prestigious Green Star rating,” says Muller.

The results showcased South Africa as one of the top performers worldwide, reporting the highest percentage of green building projects currently under way. Even more impressive is the fact that South Africa’s commitment to green building isn’t triggered by regulatory requirements, as is the case in many other jurisdictions, but by ‘doing the right thing’.
Dodge Data & Analytics and United Technologies published ‘World Green Building Trends 2016’ this month, on which the World Green Building Council (WorldGBC) was a research partner.
The report states that respondents in South Africa believe the green activity so far is just laying the groundwork for an overall shift in the market. If this degree of commitment to green building holds, South Africa will be a leader in the global green market in the next three years.
The report finds that, internationally, twice as many companies are expecting their building projects to be certified green by 2018 – an increase to 37%. In comparison, respondents in South Africa indicated that 41% of their work is already green.
“South Africa will continue to outperform with almost two thirds of respondents expecting more than 60% of their projects to be green by 2018,” says Green Building Council South Africa (GBCSA) CEO, Brian Wilkinson.
Especially noteworthy is that South African green building is driven by an acknowledgement that green building is ‘the right thing to do’, rather than by regulations, according to the report.
“In South Africa, there is an absence of regulatory requirements – which, in countries like the UK, Australia and Singapore, are in fact the trigger for green building,” explains Wilkinson. It’s testimony to the work being done by the GBCSA.
The GBCSA certified South Africa’s first green building project in 2009. In May 2015, the council certified its 100th building project, and today, there are 167 certified projects.
“It’s a clear sign that green building practices are gaining significant momentum in South Africa, along with an acknowledgment that Green Star certified projects are not only world-class and innovative, but benefit people, the planet and profits,” concludes Wilkinson.
According to a study (see attachment) entitled, World Green Building Trends 2016, Developing Markets Accelerate Global Green Growth, the percentage of companies expected to have more than 60 per cent of their building projects certified green is anticipated to more than double by 2018, from 18 per cent currently, to 37 per cent.
The anticipated growth will largely be driven by countries that still have developing green markets, with firms from Mexico, Brazil, Colombia, Saudi Arabia, South Africa, China and India reporting dramatic growth in the percentage of their projects that they expect to certify as green.
The study, from Dodge Data & Analytics and United Technologies Corporation, on which the World Green Building Council (WorldGBC) was a research partner, features the results of more than 1,000 building professionals from 69 countries – including Green Building Councils and their corporate members, from architects and contractors, to owners and engineers.
The study identified a green project that is either certified or built to qualify for certification under a recognised green standard, such as LEED, BREEAM, the DGNB System, Green Star and many other tools.
Other key findings from the report include:
- Global green building continues to double every three years.
- Brazil expects six-fold growth in the percentage of companies that expect to certify the majority of their projects green (from 6 per cent to 36 per cent); five-fold growth is expected in China (from 5 per cent to 28 per cent); and four-fold growth is expected in Saudi Arabia (from 8 per cent to 32 percent).
- Building owners report seeing a median increase of 7 per cent in the value of their green buildings compared to traditional buildings (an increase that is consistent between new green buildings and those that are renovated green).
- The most widely reported benefit globally is lower operating costs. But around 30 per cent of respondents also consider documentation and certification providing quality assurance, education of occupants about sustainability, and higher value at the point of sale as additional benefits which are important in their markets.
- The top sector for green building growth globally is commercial construction, with nearly half (46 per cent) of all respondents expecting to do a green commercial project in the next three years.
- Reducing energy consumption continues to be the top environmental reason for building green (selected as one of the top two reasons by 66 per cent of all respondents), protecting natural resources ranked second globally (37 per cent), and reducing water consumption ranked third (at 31 per cent).
Terri Wills, CEO of WorldGBC, and who is interviewed as a thought leader in the study, said: “This study offers further evidence on the strong business case for green building – the growth of which is now truly a global phenomenon. Green building is playing a critical role in the development of many emerging economies, particularly as their populations grow and create a pressing need for a built environment that is both sustainable and ensures a high quality of life.
“Green Building Councils and their members around the globe will play a pivotal role in delivering this projected growth, and their leadership and expertise will be vital in realising the multiple social, economic and environmental benefits that green buildings offer.”
Three deserving Professionals and South Africa’s top rated green building picked up the coveted established Green Star SA Leadership Awards at the recent annual Green Building Convention held in Cape Town.
Sponsored by Old Mutual Property, the awards comprised of four categories. For buildings, there are the Highest Rated Building and Best Quality Submission awards, while individual professionals are recognised as either a Rising Green Star or an Established Green Star.
Brian Wilkinson, CEO of the Green Building Council South Africa (GBCSA), comments: “Our convention this year aimed to Inspire Better Buildings, and this is exactly what our leading building professionals and projects are achieving. Like us, they constantly work towards designing, building and operating better, greener buildings that tread lightly on our stressed planet. These winners are at the forefront of making a difference in the built environment. They are leading by example in the greening and sustainability space.”
As the sponsors of the Green Star SA Leadership Awards this year, Regional Manager for Old Mutual Property, Faieda Jacobs, says they are proud to be a part of the event.
“Old Mutual Property is committed to sustainable development, and the breadth and quality of entries submitted only serves to prove there are many corporates out there starting to come on board too. We see our participation in the awards as an important step in building a better future for South Africa,” she says.
Hotel Verde in Cape Town was officially named the winner in the Highest Rated building category for its Existing Building Performance (EBP) Pilot tool rating. Hotel Verde is owned by Mario Delicio, with Andre Harms from Ecolution as the project’s Accredited Professional (AP).
Wilkinson explains: “This award is given to the project that attains the highest points in the final rating for the 12 month period under consideration. Hotel Verde, with its 6-Star Green Star SA EBP rating, showcases some of the most advanced, environmentally conscious technological installations, construction methods, procurement and operational practices of any hotel in the country.”
Runner up in this category, Upper Grayston Building in Sandton Central, Johannesburg was recognised for its 6-Star Green Star SA Office v1 As Built rating. It is owned by Tower Property Fund and its Accredited Professionals were Annelidé Sherrat and Marloes Reinink of Solid Green.
The best quality submission award was won by Solid Green’s Dash Coville, for his work as the green building Accredited Professional on the Monte Circle Building A development. The development received a 4-Star Green Star SA Office v1 Design rating and achieved a score of 98% of points targeted. Monte Circle is owned by Abland.
The runner up in this category was Sally Misplon for her work as the green building Accredited Professional on the Gatehouse Building at Black River Park in Observatory, Cape Town. The building received an EBP Green Star SA rating and is owned by Redefine Properties.
Acknowledging outstanding and ongoing contribution to green building in South Africa, Alison Groves of WSP was awarded the Established Green Star. Jaco Kemp of Arup was named the runner up in this category.
“We consider it very important to recognise those who have continually contributed to the green building economy and, in particular, through Green Star SA buildings,” says Wilkinson.
Mauritz Kruger of RHDVH was named this year’s Rising Green Star and Nick Gorrie of Agama was the category’s runner up.
“The future is indeed bright with professionals like these working together for a better built environment.” Wilkinson says.
In 2009 the country’s first green certification was awarded by the GBCSA. In April 2014 the country celebrated 50 Green Star SA ratings; and, to date, the number of Green Star SA ratings has nearly tripled to 140 certified projects.
Wilkinson concludes: “The significant growth in green building is thanks, in part, to the support of our sponsors. Having achieved 100 certifications in April this year, we have been overwhelmed by the commercial property sector’s commitment to sustainability and resource efficiency.”
Solid Green Consulting has successfully facilitated 20 Green Star SA certifications with the Menlyn Maine Pegasus building marking this milestone.
Menlyn Maine Pegasus received a 4 Star Green Star SA – Office v1 Rating from the Green Building Council South Africa (GBCSA) on 22 September 2015. Solid Green consulting was founded in 2010 by Marloes Reinink and is celebrating its fifth anniversary this year. The company completed its 10th certification in December 2014, four years after it was formed.
In 2015 another 10 ratings have been achieved. These Green Star SA ratings include Design and As-Built ratings for New Office buildings, a Public Education building, a Multi-unit Residential building, Office Interior ratings and Existing Building Performance ratings. The Menlyn Maine Pegasus project is an important landmark to celebrate the company doubling its output over the last year.
Manfred Braune, Chief Technical Officer at the GBCSA says: ‘The GBCSA congratulates Solid Green on achieving this significant milestone and for becoming a leading consulting firm in the green building sector, having been responsible for a very significant proportion of the 130 Green Star SA certifications to date. It is organisations such as Solid Green that are key enablers, working with the GBCSA, to transform the built environment into a more sustainable one. ‘
Menlyn Maine Pegasus was the very first building registered with the GBCSA for a Green Star SA Rating in 2009. It is a located on the corner of January Masilela Drive and Amarand Avenue, Pretoria and will house Regus and BMW amongst others. The developers of Menlyn Maine have their sights set on certifying all the buildings in the precinct. Menlyn Maine has brought together a group of professionals who are already well versed in sustainable building design and construction in order to make a green precinct possible.
Pegasus includes passive design initiatives such as using the building orientation and sizing of the floor plates for optimal daylight in the building, and using the site and building hard surfaces to collect rainwater. Sustainability initiatives have been drawn through design into construction by, for example, making use of coated glazing for improved thermal control, concrete with reduced cement content and recycled steel in the rebar. Building services are optimised to improve building performance and to reduce energy and water consumption which in turn is actively monitored by a Building Management System (BMS).
Solid Green Consulting is a sustainable building consultancy based in Rosebank, Johannesburg. Over and above green building consulting services, Solid Green has also developed building energy monitoring solutions through Solid Insight and building energy modelling services.
