HVAC The underfloor mechanical air conditioning system addresses both energy efficiency and good indoor environmental quality . The system supplies cool fresh air from the raised floor , which then absorbs warmth as it rises and is extracted at ceiling level , thereby effectively preventing the build up of pollutants .
The architectural vision and mechanical design of the building has ensured optimal indoor environmental quality for those work-ing inside the building so as to promote health and wellbeing . Building users have access to striking external views , ample natural daylight and care has been taken to specify paints , wood products and carpets that contain no harmful compounds that could possibly be inhaled by tenants when working inside the building .
Further to this , the building has been designed to also provide quality outdoor environments : a private roof garden , propo-gated with only endemic vegetation , and overlooking the harbour and Cape Town City bowl , provides a space for tenants to relax or work outdoors . A small herb garden helps to contribute to the daily food prepared in the buildings kitchen and composting units will , in turn , recycle organic waste generated in the kitchen .
In addition to the low flow water fittings that have been specified to promote water efficiency , a grey water system has also been installed to save potable water . Waste water from hand wash basins and showers will be collected , and treated within the grey water system , and reused for flushing water in the toilets .
