NABERS Energy  
  The NABERS Energy rating for offices, previously known as the Australian Building Greenhouse Rating (ABGR), was launched as ABGR in 1998.

NABERS Energy assists owners and tenants to reduce energy use, reduce energy costs and reduce greenhouse emissions. It benchmarks a building’s greenhouse impact on a scale of one to six, one star being the most polluting and six stars the least. Experience shows that by implementing energy efficiency practices many buildings can save 20 to 40% on their energy bills and reduce the emission of greenhouse gases.

Currently, NABERS ratings for offices include NABERS Energy, NABERS Water, NABERS Waste and NABERS Indoor Environment.
