According to Mirvac, Sirius House in Canberra has become the first building in Australia to achieve a 6 Star NABERS Energy rating, a 6 Star NABERS Water rating and a 6 Star Green Star Performance rating, without the use of green power or externally sourced recycled water.

Mirvac’s Office and Industrial Sustainability manager, David Palin says, “Being the first property group to achieve 6 Star NABERS ratings across water and energy, and for Green Star performance at Sirius, without Green Power or externally supplied recycled water, is a huge accomplishment for Mirvac, and one that we are all extremely proud of.”

“It’s a testament to the hard work and dedication of a number of teams at Mirvac, and their continued focus on optimising energy and water performance at this asset.”

“In fact, he says,  “…since 2013, carbon emissions have reduced by 33 percent, while water consumption has reduced by over 50 percent.”

Sirius House was also the winner of the Facilities Management Team Award at the CIBSE Building Performance Awards in London, which recognised the Mirvac’s ongoing commitment to reducing energy and water usage.

The A-grade asset, which covers over 46,000sqm of office space, is currently performing 1 Star above its original design and As-Built Green Star ratings, and also 1 star above its NABERS Energy Design target.
