SA's largest green building gets 6-star rating

Cape Town has made green building history with the announcement by the Green Building Council of South Africa that No 1 Silo at the V&A Waterfront has been given the country's first 6-star Green Star SA 'As Built' rating.

The No1 Silo office building at the V&A Waterfront.
The announcement was made at FNB's Portside building during the Green Star Leadership Awards 2014, which form part of the Green Building Convention in Cape Town this week.

The No 1 Silo has previously received the Western Cape's first 6-star Green Star SA rating for design from the council. This makes it the first development to receive six green stars for both its design and the completed building.

The 18 500m2 office building was designed and built to be the new headquarters of blue-chip tenant Allan Gray.

The building was also the overall winner at the prestigious SA Property Owners Association (Sapoa) Innovative Excellence in Property Development Awards 2014 earlier this year, when it also won the corporate office development category and the overall green award.

Brian Wilkinson, chief executive of the Green Building council said: 'We're thrilled to award the maiden 6-Star Green Star SA As Built rating to such a deserving development.'

Manfred Braune, chief technical officer of the Green Building council, said the Green Star SA Design ratings were important as they showed green and sustainable elements were being considered in a new building development, right from the start.

'But 'As Built' ratings are perhaps more crucial as they show developers are following through on the green objectives set out in the design of the buildings.'

The No 1 Silo is one of two buildings that make up the first completed phase in the new Silo Precinct of the Waterfront.

It includes electric-car charging points in the basement, low-flow water fittings and a private roof garden. Key sustainability features include the high-performance, fully glazed, double-skin glass façade that maximises views, including those over Silo Square and Table Bay, and it also ensures optimal use of natural light.

It has a seawater cooling system and uses seawater to reject waste heat from the cooling plant which allows for significant potable water savings and improves the overall efficiency of the building.
