Mirvac Group is pleased to announce that 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, said the achievement reflected the Group’s steadfast commitment to operational and sustainability excellence at its assets.
“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, since FY13, carbon emissions have reduced by 33 per cent, while water consumption has reduced by over 50 per cent. This is aligned with our Group target to be net positive on carbon emissions and water by 2030.
“Our relationship with our tenants, the Department of Health, has also been instrumental in our efforts to improve the building’s operational efficiency.”
Located at 23 Furzer Street in Phillip, ACT, Sirius House was the first major office building in Australia to achieve a 6 Star NABERS Energy rating. It was also the winner of the Facilities Management Team Award at the CIBSE Building Performance Awards in London, which recognised the teams’ ongoing commitment to reducing energy and water usage.
The A-grade asset, which covers over 46,000 square metres of office space, is currently performing 1 Star above its original Design and As-Built Green Star ratings, and 1 star above its NABERS Energy Design target.
In 2014, Mirvac installed its first large-scale solar PV system at Sirius House as part of its sustainability strategy, This Changes Everything, and a target of delivering one megawatt of renewable energy by 2018.
