Mirvac Group’s One Darling Island office precinct in Pyrmont has scored a 6 star NABERS Energy rating – and it’s been achieved without the use of GreenPower.
One Darling Island is now one of only nine buildings in Australia to hold a base building 6 star NABERS Energy rating and becomes the third asset within Mirvac’s office portfolio to achieve a 6 star NABERS Energy rating.
One Darling Island joins Sirius House in Canberra and the nearby Bay Centre which both boast coveted 6 stars NABERS Energy credentials.
David Palin, Mirvac’s sustainability manager, attributed the achievement to a combination of factors: a high-quality, flexible base building; a “firm focus” on energy efficiency; investment in renewable energy; and partnership with tenants.
“Mirvac designed and constructed the building in 2006 with embedded flexibility and future-proofing which has allowed for continual improvements to be made to its environmental performance,” Palin explains.
“Our team has worked ever since to capitalise on this potential by implementing a range of energy efficiency initiatives and installed 100 kilowatts of solar on the roof of the building in 2017.”
The efforts are reaping rewards. Energy consumption at One Darling Island has been cut by 28 per cent and carbon emissions by 39 per cent since the 2013 financial year.
The A-grade asset, which covers more than 22,000 sqm of office space, is currently performing 1.5 stars above its NABERS Energy target.
A 6 star NABERS rating is the highest, indicating market leading environmental performance.
“Achieving a 6 Star NABERS Energy Rating is a great accomplishment,” says Dennis Lee, senior team leader at the NSW Office of Environmental Heritage, which administers the NABERS system.
“One Darling Island has joined an elite group of buildings in the top one per cent nationally at this level of performance. Mirvac has demonstrated an ongoing commitment to energy efficiency at One Darling Island, reaching 6 stars this year by cutting its energy use by a further 25 per cent.”
Mirvac’s Bay Centre office, also in Pyrmont, was the first building in New South Wales to achieve a 6 star NABERS Energy rating in 2016.
In 2018, Mirvac’s Sirius House in Canberra was the first building in Australia to achieve a ‘trifecta’ – 6 star NABERS Energy, 6 star NABERS Water rating and 6 Star Green Star Performance – without the use of GreenPower or externally sourced recycled water.
Mirvac aims to be carbon positive by 2030.
