Alice Lane Phase II
Alice Lane Phase II, a 16 000 m² building, is the head office of insurance giant Santam/Sanlam. The building is located on Alice Lane in Sandton, Johannesburg, and comprises six office levels and seven parking levels.7
The project achieved a 4-star Green Star SA Office v1 Design certification in December 2013, and a 4-star Green Star SA Office v1 As-Built certification in January 2016.
Sustainable Building Features
- Building is mechanically ventilated. Heating and cooling is provided by means of a four-pipe central chilled-water system, using air-cooled reversible heat-pump chillers and four-pipe in-ceiling fan coil units.
- Chillers placed on the roof make use of the compression cycle of refrigerants in order to transfer heat from the chilled water circuit to the atmosphere.
- The building has reduced energy consumption to 165 kWh/m² /year and carbon emissions to 198 kgCO2 /m² /year.
- The building has a groundwater harvesting system.
- The main electrical supply to the building is made up of two sections, a critical section, which is backed up by a generator, and a non-critical section. The non-critical section feeds items such as the main HVAC chillers, pumps, and items that do not require generator backup during a power failure. All other items are backed up via the generator, which provides the emergency backup required for the building.
- The fire-protection system has been designed to not expel any water during testing. Water is redirected back into storage tanks.
