The major innovation in ESD is the fully glazed double skin façade with ventilated cavity and automated venetian blind system. It provides shading for the building while maximising views to the harbour and optimising daylight levels. A naturally ventilated glass atrium ascends the full 130 metre height of the building, providing transparency and fresh air to every floor.
Solar thermal collectors inject high temperature energy into a cooling system that provides enough energy to allow 100 per cent more fresh air to be pumped through the building without any additional running costs. The solar cooling system feeds into a tri-generation system that provides free cooling and heating to the building, minimising strain on the CBD grid infrastructure.
A black water recycling system - the first in a Sydney CBD tower - reduces water consumption by providing clean water for the washroom flushing system.
