Other aspects of the building’s
sustainability features include the
following:
• power: the building has a specific
energy strategy with passive and active
energy as well as a solar array on the
roof which harvests additional power
when the sun is shining. In the case of a
grid failure, vital systems in the building
are kept going by means of a standby
generator;
• water resources: the building employs
low water flow devices in keeping
with Cape Town’s status as an arid city.
A 100m3 greywater and rainwater
harvesting system provides water for
toilet flushing and landscape irrigation.
