Abstract: The Australian Building Greenhouse Rating Scheme is an operational energy efficiency rating scheme, using energy bills, floor area and basic occupancy data to create an index from one star (poor performance) to five stars (excellent performance). Two to two and a half stars represents average performance. The rating scheme has been widely accepted as a means of assessing the energy performance of existing office buildings in Australia, being in widespread use by consultants and portfolio owners alike.
In this paper, the background of the scheme is described, covering technical aspects and the basic market philosophy. The operation of the scheme is also discussed, highlighting the accredited rating process which provides quality assurance for the ratings. Accredited ratings have been accepted in NSW as a means of calculating greenhouse gas credits.
The scheme also has found applications in the new buildings sector, where the rating is used to set a post-construction performance target for office building developments.
Overall the rating has had a significant impact on the market and provides a simple, reliable benchmarking methodology for office buildings.
