Western Australia is leading the country in reducing greenhouse gas emissions in office buildings according to a new Australian Building Greenhouse Rating (ABGR) analysis.
Energy Minister Francis Logan said WA had more buildings with a 4, 4.5 or 5-star ABGR rating than any other State.
“Nearly 16 per cent of our buildings have achieved this high rating, compared with only 2.7 per cent in Victoria, 3.9 per cent in Queensland, 4.6 per cent in South Australia and 11.8 per cent in New South Wales,” Mr Logan said.
The ABGR program, administered in WA by the State Government’s Sustainable Energy Development Office, uses a one-to-five star rating to benchmark an office building’s energy related greenhouse impact.
One-star buildings have the worst greenhouse performance, with well-designed and managed existing buildings typically achieving a 3 or 3.5 star rating.
A five-star rating shows market leading performance in a building’s energy efficiency.
Some of Perth’s highest rating buildings include the Australian Taxation Office in Francis Street, Wellington House in Wellington Street, The Atrium in St Georges Terrace and NRMA House in Colin Street.
Buildings under construction that have committed to high ABGR ratings include the Century City complex in St George's Terrace, the Raine Square development at the corner of Wellington and William streets and Bishop’s See in St George's Terrace.
The Minister said the average ABGR in the Perth CBD was 3.15 stars, compared with the national average of 2.9 stars.
“These outstanding results indicate that many in the WA property sector are demonstrating a major commitment to energy efficiency and are leading the way in lowering the greenhouse emissions from commercial buildings,” he said.
“Commercial buildings contribute about 10 per cent of Australia’s total greenhouse gas emissions. By using simple efficiency initiatives, it is estimated that savings of 20 to 40 per cent are possible in existing buildings.
“Rating a building’s energy performance allows for potential reductions to be identified, while also allowing for comparisons with other buildings.”
