Sustainability The Stats SA building achieved a 4 Star- Green Star SA Office v1 Design rating in the 1st assessment round. Sustainable building features include:
Energy Efficiency The project reduces its peak demand on energy supply infrastructures by 32.9 % via the installation of an ice storage system. Stats SA has shown a 60 % improvement in predicted Carbon Emissions over a SANS 204 Notional Building, minimising the greenhouse gas emissions associated with operational energy consumption. The building has also incorporated energy sub-metres to accurately record the consumption of power and lighting used within the building.
Other energy saving strategies such as efficient, high frequency ballast have been incorporated in the building and a BMS system has been provided to monitor consumption of the building. Photovoltaic( PV) panels will be installed on a part of the roof to first drawing energy from the panels before using the mains power connection to meet the demand.
of the occupants. Windows are minimised on the east and west façades to minimise the heat load due to the low sun angle on the east and west, which is especially important to avoid in office buildings.
Materials The project has reduced the impact on resources by minimising the use of PVC by 30 % and the minimisation of absolute quantity of Portland cement by 30 % for in-situ concrete, 20 % for precast concrete and 15 % for stressed concrete.
Land Use and Ecology The project has minimised the impact for the need to clear undeveloped land that might cause urban sprawl by reusing a previously developed site and enhancing the ecology value of that site with the large areas of endemic landscaping.
Water Efficiency The irrigation design has reduced the demand for potable water use by 90 %. This is mainly achieved by having a large endemic veld landscaping around the building. A further reduction on potable water consumption has been achieved by the use of water efficient sanitary fittings. Water metres have been provided to monitor and manage water consumption of the office building in conjunction with the BMS System.
Indoor Environmental Quality The building’ s orientation is such that the wings are orientated north / south, meaning that it is well orientated to respond to the climate, enhancing the comfort and indoor environment
