One Darling Island Scores 6 Star Rating

17th December 2018

One Darling Island, Pyrmont, has achieved a 6 star NABERS Energy rating, becoming the third asset within Mirvac’s Office portfolio to do so.

One Darling Island in Pyrmont has achieved a 6 Star NABERS Energy rating without the use of GreenPower.

It 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 the 6 Star Energy rating. It joins Sirius House in Canberra and the nearby Bay Centre which both hold the coveted 6 Stars for Energy.

Mirvac’s Sustainability Manager, David Palin, said the combination of a high quality, flexible base building, the team’s firm focus on driving energy efficiency, investment in renewable energy and the commitment and contribution of its valued partners made this achievement possible.

“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. Our team has worked ever since to capitalise on this potential by implementing a range of energy efficiency initiatives and installed 100kW of solar on the roof of the building in 2017.”

“As a result, energy consumption has reduced by 28% and carbon emissions have decreased by 39% since FY13, the baseline year of our Sustainability Strategy, This Changes Everything. This performance also directly contributes to Mirvac’s target to be net positive in carbon by 2030. In conjunction with the Mirvac Asset Services team, our partners, including building automation solution and management providers, Alerton, have played a key role in improving the building’s operational efficiency.”

Dennis Lee, Senior Team Leader in the Strategic Delivery Office at the Office of Environment and Heritage said, "Achieving a 6 Star NABERS Energy Rating is a great accomplishment. One Darling Island has joined an elite group of buildings in the top 1% 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%.”
