Double Skin Facades: The Cutting Edge

Ray Brown

Winner of the Best Tall Building Asia and Australasia award in 2012, the 28-story 1 Bligh Street is moderately-sized in comparison to conventional tall buildings, but it is a building packed with many innovative environmental technologies that were being used for the first time in a commercial tower in Australia – including a double skin, fully shaded automated façade, a full-height naturally ventilated atrium with breakout spaces, solar thermal tubes, and a tri-generation system that uses gas and solar energy to generate cooling, heating, and electricity. 1 Bligh’s standout feature is undoubtedly the fully glazed double-skin façade that was specifically developed to optimize amenity for occupants and to facilitate continuous perimeter offices, among other fit-out options, without the complication of external columns that block views, creating a high degree of equitable floor space. This presentation examined the four critical considerations that informed 1 Bligh’s design: the view, the public space, the work environment, and green building.
