NABERS Energy and Water for Offices Rules

06 Mar 2023

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 version of the Energy and Water for Offices Rules is v5.0. (please note below the transition period for this version to come into effect).

    What's new in this version?

    • Prioritisation of an Owner/Tenant Agreement (OTA) as the preferred method for determining rated hours for all rating scopes.
    • An allowance for virtual site visits when certain criteria are met.
    • Changes to how data is collected and reported to align with the transition of Offices ratings to the NABERS Perform platform.

    Transition period

    The NABERS Energy and Water for Offices Rules v5.0 will come into effect in Q2/2023. This release will coincide with the transition of Offices ratings to NABERS Perform, the launch of the Renewable Energy Indicator, and release of the NABERS Metering and Consumption Rules v2.0. (NOTE: an exact date will be advised closer to the time).

    Assessors must continue to use the NABERS Energy and Water for Offices Rules v4.1 until the revised v5.0 comes into effect. If this transition is a cause for concern, please contact nabers@environment.nsw.gov.au.
