           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.
