Redefine Properties’ “green over” of The Towers, nearing completion in Cape Town’s CBD has significantly improved energy efficiency at this property.
The Towers, formerly known as the Standard Bank Centre, is likely to get an initial 3-Star Green Star SA rating from the Green Building Council of SA on completion when it is certified. In terms of the existing building rating tool, further annual assessments will follow which allow asset management to improve the rating further as time proceeds.
Daryl Sher, Development Manager of Redefine Properties, said it has been challenging to make changes to an existing building that would have only managed to get a 1-star rating for energy efficiency, while it was still occupied by tenants. The Towers has remained operational throughout the upgrade, and forms part of the Green Star SA Existing Building Performance pilot programme.
“By keeping in tune with environmental innovations and trends, Redefine is able to offer tenants the latest cutting-edge technology in our new and existing buildings. In this way, our properties rely less on the grid and our tenants benefit financially too,” said Xander Rau, Coastal Regional Development Manager of Redefine.
The green refurbishment of The Towers includes a new flushed glazed system on its external facades that will reduce the cooling demand by approximately 30%. Redefine is also investigating the installation of photovoltaic solar panels on the tower roofs, to save energy. The common areas of the building have been fitted with energy-efficient lighting using timer controls and the lights in these areas will be automatically switched off when not in use.
Andrew Konig, CEO of Redefine, said green buildings were more attractive to tenants and investors because of their triple-bottom line commitments to building efficiency, social sustainability and environmental sustainability.
“Businesses are looking for buildings that will complement their sustainability ethos and practice. Turning new or existing buildings into green buildings make them more profitable, which in turn has positive spin-offs for the economy.” Studies also indicate that properties designed or refurbished in line with sustainability guidelines improve tenants’ productivity and wellbeing.
Redefine Properties’ Black River Park office park in Observatory, Cape Town, is also the first office campus in the country to obtain a range of “existing building certifications” from the GBCSA including four, five and six star ratings for eight of its assets.
In addition to new developments and upgrades in Cape Town, Redefine is currently developing several sustainable commercial office buildings in Johannesburg. The company has already achieved a 4-Star Green Star SA design and as built rating from the GBCSA for its 90 Grayston development in Sandton, which has been recognised as one of South Africa’s most innovative and recognisable buildings. Soon to be completed will be the 90 Rivonia commercial offices in Sandton which will be mostly occupied by Webber Wentzel Attorneys (in association with Linklaters), and the Rosebank Towers building in Rosebank which will house amongst other blue chip tenants, Redefine’s new offices. Both these buildings will be 4 star green rated highly functional and iconic assets.
