Pioneering sustainability

• Sydney’s first 6 Star Green Star workplace. Darling Quarter, designed for Lend Lease, achieved 6 Star Green Star under Office As Built v3 in early 2012.
• The first public library to achieve both Design and As Built 5 Star Green Star ratings. Melton Library and Learning Hub achieved both ratings under the Green Star Public Building pilot tools: Design PILOT in 2013 and As Built PILOT in 2014.
• Air cleaned by plants. At Surry Hills Library and Community Centre, biofiltration planting in a glazed environmental atrium filters air drawn in from outside.
• Cooling from thermal labyrinths. Thermal mass labyrinths cool incoming air at Surry Hills Library, the Tyree Energy Technologies Building and Bankstown Library and Knowledge Centre, where the labyrinth is built from salvaged concrete panels.
• Pioneering carbon-conscious design. At Legion House, the heritage refurbishment was designed to the Australian Sustainable Built Environment Council’s definition of a zero carbon building, and for on-site power from the gasification of materials including waste paper from the adjacent office tower.
• Australia’s first closed cavity facade. At 200 George Street, the closed cavity facade (CCF) is the first in the world to integrate automated timber blinds, which track the sun to control heat gain and glare.
• Powered by the sun. A 150 kW photovoltaic array covers most of the roof of the Tyree Energy Technologies Building at UNSW, which achieved 6 Star Green Star under Green Star Education v1.
