Green Star assesses the sustainable design, construction and operation of buildings, fitouts and communities. There are four Green Star rating tools available for certification of design, construction and operation of buildings, fitouts and communities. The tools cover a broad range of sustainable topics including energy and emissions and provide an overall rating, with 4-stars meaning “best practice, 5-star meaning Australian excellence and 6-star meaning international excellence. The program is voluntary and covers the residential, office, retail, accommodation, education and public buildings
The Australian Government's National Carbon Offset Standard for Buildings (the standard) provides industry a recognised, streamlined and agreed way to claim to be a carbon neutral building in operation.
The GBCA now offers a certification pathway against the standard through integration in Green Star – Performance v1.2.
Buildings in operation can be assessed for carbon neutrality at the same time as seeking a Green Star – Performance rating, and benefit from synergies of parallel assessment to achieve certified ratings.
The Australian Government's National Carbon Offset Standard for Buildings has been established through collaboration between the Australian Government Department of the Environment and Energy, GBCA and NABERS.
