Minimisation of Greenhouse Gas Emissions associated with operational energy consumption is reduced . An energy model of the building was generated and in the design stages of the building compared to a notional building model . The building design showed an improvement of 100 % ( net zero operating emissions base building ) over a SANS 10400 notional building .
The buildings peak electrical demand is actively reduced by the use of photovoltaic systems .
The office lighting design ensures the use of artificial lighting with minimal energy consumption as the energy use of 1.5W / m 2 per 100 Lux was set for the office lighting power densities .
All selected gaseous and fire suppression systems and thermal insulants used for the development have an Ozone Depleting Potential ( ODP ) of zero , to eliminate any contributions to long-term damage to the earth ’ s stratospheric ozone layer .
A project specific Environmental Management Plan was developed and implemented throughout the duration of construction to establish guidelines to follow to minimise the environmental impact associated with construction activities .
A project specific Waste Management Plan was developed and implemented to minimise the contribution of waste going to landfill . And reduce the environmental impact of the project .
The building achieves a savings through the use of water efficient fittings that limit the occupant water usage to 0.56 L / day / m 2 .
Sub-metering of major water consuming systems is in place . Gathering information is key to understanding and managing building systems and to assess opportunities for water savings .
The project is targeting more than one certification , i . e ., Green Star Office v1.1 Design and As-built ; Net Zero Carbon and Interior v . 1 .
