What does a NABERS star means?

NABERS is a national rating system that measures the environmental performance of Australian buildings, tenancies and homes. Put simply, NABERS star measures the energy efficiency, water usage, waste management and indoor environment quality of a building or tenancy and its impact on the environment.

It does this by using measured and verified performance information, such as utility bills, and converting them into an easy to understand star rating scale from one to six stars. For example, a 6 star rating demonstrates market-leading performance, while a 1 star rating means the building or tenancy has considerable scope for improvement.

NABERS for Offices

NABERS star ratings for offices can be used to measure the performance of a tenancy, the base building or the whole building:

  • The tenancy rating includes only the energy or resources that the tenant controls.
  • A base building rating covers the performance of the building's central services and common areas, which are usually managed by the building owner.
  • A whole building rating covers both the tenanted spaces and the base building, and is typically used in an owner-occupied building, or where there is inadequate metering to obtain a base building or tenancy rating.

Program using NABERS: Commercial Building Disclosure (CBD) Program

The Commercial Building Disclosure (CBD) Program is an initiative of the Council of Australian Governments (COAG) and was established by the Building Energy Efficiency Disclosure Act 2010 managed by the Australian Government Department of Industry.

The CBD Program requires most sellers and lessors of Office buildings or tenancies with more than 2000 m2 of net lettable area, advertised for sale or lease, must disclose a BEEC (Building Energy Efficiency Certificate).

The BEECs valid for 12 months and consist of:

  • NABERS star rating
  • Tenancy Lighting Assessment
  • General energy efficiency guidance
