Green features include a basement sewage plant that recycles 90 percent of the building waste water, solar panels on the roof and air conditioning by chilled beams. It is Australia’s first major high-rise building with a full double-skin façade with external louvres. These conserve energy, eliminate sky glare and optimise user comfort. The angle of the louvre blades is automatically adjusted according to their orientation to the sun. A naturally ventilated, full height atrium, on the southern side of the building, maximises natural light to each office level.
