The NABERS Energy and Water for Offices Rules are used by Assessors to rate the energy and water performance of office buildings.
NABERS ratings must be performed by a NABERS Accredited Assessor and comply with the quality standard set in the principles and rules for gathering, interpreting and using data.
The latest versions of the Rules are:
- Version 4.1 of the NABERS Energy and Water for Offices Rules; and
- Version 1.2 Metering and Consumption Rules.
Transition Period
A transition period for the NABERS Metering and Consumption Rules applies starting from 22 December 2020, during which office energy and water ratings could follow either:
- NABERS Energy & Water for Offices Rules (v4.1) and NABERS Metering & Consumption Rules (v1.1); or
- NABERS Energy & Water for Offices Rules (v4.1) and NABERS Metering & Consumption Rules (v1.2).
This transition period will last until late February 2021 and is tied to the release of NABERS Perform. Further details on the end of the transition period will be sent to all assessors in February 2021.
Rating applications submitted as part of a commitment agreement are exempt from this requirement.
If you have any questions regarding the transition period, please contact nabers [at] environment.nsw.gov.au (subject: NABERS%20%7C%20Office%20Rules%20%7C%20Transition%20period%20query) .
