NABERS is short for National Australian Built Environment Rating System. It measures the energy efficiency, water usage, waste management and indoor environment quality of Australian buildings, including tenancies and homes, and its impact on the environment. It does this by using measured and verified performance information, such as utility bills, and categorizing it in their 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.
Are you aiming to get a 6 star rating in your NABERS assessment? If you are, then here are the information you need to prepare for:
1. Rating Type
- Tenancy – tenanted space
- Base building – central building services and common areas
- Whole building – combination of a & b
2. Finding an Accredited Assessor
- All of the Accredited Assessors are in the NABERS website (www.nabers.gov.au). Only the assessors in this list are qualified to give your office an assessment.
3. The Rating Application Process
- The Accredited Assessor that you employ will calculate and submit your rating application with the Office of Environment and Heritage (OEH). After verifying your application, OEH will produce a rating certificate within two working weeks from receipt of the application.
