NABERS Indoor Environment for Offices Rules

09 Sep 2025

The NABERS Indoor Environment for Offices Rules are used by Assessors to rate the indoor environment quality of office buildings.

A NABERS Indoor Environment rating assesses a building or tenancy’s indoor environment against a set of benchmarks which reflect current industry standards and scientific research.

The assessment 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 for a rating to be accredited by NABERS.
