BUILDING: Aurecon Gets First 5 Star Green Rating
Recent Western Cape Business News
AURECON’s office building in Century City, Cape Town is the first building in South Africa to be awarded a 5 Star Green – Office Design rating by the Green Building Council of South Africa (GBCSA).
Developed by the Rabie Property Group at a cost of around R130 million, the 7 000 sq m office block is also the first building in Cape Town and only the fifth country-wide to achieve Green Star accreditation from the GBCSA. The four other buildings all achieved a 4 Star rating.
The new building will serve as the new regional offices for engineering, management and specialist technical services group Aurecon who were responsible for the design of all the engineering services on the project and also the Green Star Rating application.
Rabie director Colin Anderson, who was responsible for the development, says they were pleased with the achievement which was “doubly amazing given that we had to complete the building within a normal commercial budget”.
“Increasingly, it has become important to demonstrate that our own buildings and facilities have been built in a sustainable manner. The group is committed to ensuring that we design and execute sustainable and environmentally responsible infrastructure projects and we have ensured that our teams include suitably trained and registered professionals, including environmentalists and Green Star SA Accredited Professionals,” says Albert Geldenhuys, Aurecon’s general manager: South Africa.
Anderson says the 5 Star rating was achieved for the design of the building. “However, as the building has been built to design there is no reason stopping us from also applying for an As Built Green Rating from the GBCSA. Only one other building in the country has so far achieved a Green Star rating in two categories and this was the Nedbank building in Johannesburg which achieved a 4 Star Green Star SA – Office Design v1 and a 4 Star Green Star SA – As Built v 1,” he says. Aurecon fulfilled the role of mechanical engineer and carried out specialist modeling for the green star submission for this project.
Anderson said in their quest for a Green-Star rating the professional team and building owners took into account the Green-Star SA criteria, namely Management, Indoor Environmental Quality, Energy, Water, Transport, Materials, Emissions, Land Use and Ecology and Innovation.
Finance for the development was provided by Nedbank Corporate Property Finance who has a long-standing relationship with the Rabie Group.
The four storey building, which has been constructed on a podium covering a naturally-ventilated semi-basement of covered parking, was designed by MaC Architects and its orientation ensures maximum indirect sunlight and reduced east and west direct sunlight.
Other green measures undertaken include:
• A modern air-conditioning system with a full economy cycle to provide free cooling when outside conditions are favourable
• A modern Building Management System which monitors and controls energy consumption
• Treated effluent irrigation and the harvesting of rain water for flushing of toilets
• High-performance glazing on the windows to reduce glare and radiant heat
• Innovative measures include the implementation of a ‘Green Lease’, believed to be the first in the country, in terms of which both the landlord and the tenant have undertaken to run the building as it was designed in terms of Green building principles.
