Sydney’s first 6 Star Green Star high rise office tower, 1 Bligh Street, was officially opened by Prime Minister Julia Gillard on Tuesday, 30 August 2011.
Through intelligent and collaborative engineering design, Arup helped the client to reach world-leading environmental outcomes for the building.
The 27-storey elliptical building designed by German architect Christoph Ingenhoven and local architect Architectus is a spectacular example of innovation, sustainable design and design excellence, setting a new benchmark for office space in Australia.
Highest green rating
The Green Building Council of Australia has awarded 1 Bligh Street with the highest Green Star rating design rating, which includes the maximum allowable five points for innovation for environmental design initiative and exceeding Green Star benchmarks.
Contributing to its 6 Star Green Star and 5 Star NABERS ratings is the striking double skin façade with an automated blind providing excellent solar control while combined with highly transparent glass allowing maximum access to daylight and views.
Kerryn Coker, an Associate at Arup said: “From the innovative operable double skin façade wrapping the tower, to the 135m tall naturally ventilated central atrium extending from the ground floor wintergarden up to the glazed skylight overhead, the attention to detail is obvious throughout to create an office space of unrivalled quality.”
Arup provided mechanical and electrical services, fire engineering, acoustics, lighting design, structural steel design and façade engineering.
The anchor tenant, occupying 55% of the building, is the law firm Clayton Utz.
