171 Collins Street achieves 6 Star GBCA Green Star rating

Just 12 months on from its completion, 171 Collins Street, has become the first premium building in Australia (and the second-largest Victorian building) to achieve the Green Building Council of Australia’s (GBCA) 6 Star Green Star As Built Office v2 rating, scoring a record 83 points. The rating recognises the extensive work done by the team managing the building to meet its targets through constant tweaks, extensive day-by-day monitoring and liaison with tenants on their responsibilities.

The building’s energy performance is now meeting and exceeding the NABERS Energy 5 Star target set. Achieving a Green Star score of 83 is a fantastic reward for our extremely hard working management team and tenants, who take their responsibility to maintaining sustainable practices very seriously.

Designed by award-winning architects Bates Smart, engineered by Umow Lai and managed by Knight Frank Australia, 171 Collins Street features a myriad of best practice sustainability features in an architectural landmark that fuses a heritage façade with modern design.

In addition to the finely crafted façade, the building incorporates key environmental features to easily achieve a 6 Star Green Star and 5 Star NABERS energy rating. In particular, the use of an under-floor air distribution system provides superior indoor air quality, occupant comfort and flexibility.

The development consists of 29,800sqm of premium office space, spread over 17 large campus-style floor-plates, and 1,700sqm of boutique office space in the restored heritage building on Collins Street. The lower levels incorporate a business centre and over 1,500sqm of high-end retail space.

The building employs a number of innovative technologies including an Australian-first ceiling tile system that absorbs office pollutants to create a healthier office environment for workers, as well as grey water treatment that recycles shower water to be used in cooling towers and toilets.

Charter Hall and Cbus Property have long demonstrated a commitment to sustainability, with more than 20 Green Star projects under their belts between them. This newest Green Star rating for 171 Collins Street is a testament to their leadership, and underscores the fact that a Green Star rating is not just a mark of excellence in sustainability, but of quality.
