from SE Controls to ensure the natural ventilation and smoke control system operates effectively at the Department of Environmental Affairs’ (DEA) new head office in Pretoria. The DEA is the first government building in
O
South Africa to be awarded a 6 Star Green rating from the Green Building Council of South Africa (GBCSA). It also achieved the highest score for a large commercial office space of this scale, due to the highly energy efficient sustainable design and the extensive use of ‘green’ technologies. The three-storey head office provides more than 27,000m² of floor space and uses solar shading, water recycling and extensive photo-voltaic arrays in the north car park and on the roof, which provide more than 10 per cent of the building’s annual energy load.
