171 Collins Street, BHP Billiton’s Global Office Headquarters in Melbourne, has achieved a 6 Star Green Star “As Built” rating from the Green Building Council of Australia (GBCA).
The building is owned and was jointly developed by Cbus Property and Charter Hall. It is the first Premium Grade, 6 Star Green Star (v2) Office Design facility to be constructed in Melbourne and features 31,500 square metres of high quality commercial office space.
The latest 6 Star Green Star “As Built” rating was officially awarded in October 2014.
During construction, A.G. Coombs was responsible for designing, installing and commissioning specialist HVAC and mechanical services to both the base building and BHP Billiton’s tenancy, whilst also contributing towards the Green Star building tuning process.
A.G. Coombs is proud to have been involved in both this landmark Collins Street development and the achievement of its 6 Star Green Star “As Built” rating.
