NABERS Energy and Water for Offices Rules

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 Version 4.1

A minor update to the Metering and Consumption Rules was released on the 1 August 2021. As changes are non-technical, a short transition period has been implemented during which Assessors may use: 

• The Rules – Metering and Consumption v1.2, or 

• The Rules – Metering and Consumption v1.3. 

The transition period ends on 30 August 2021, after which only The Rules – Metering and Consumption v1.3 may be used. 

For more information, see the Metering and Consumption Rules.
