The National Australian Built Environment Rating System (NABERS) is a performance-based environmental impact rating system for existing buildings. Based on the analysis of real data, the tool allows to understand the environmental performance of any building – from offices over hotels to hospitals, from retail establishments over data centers to apartment buildings. The assessments are undertaken by independent assessors and audited by the government. Thereby, the tool facilitates smart and informed environmental decision making of developers, asset managers, and even tenants.

Tool Outcome

Assessed buildings receive a certification based on a 6-star scale (1 for poor performance – 2 for below average performance – 3 for average performance – 4 for good performance – 5 for excellent performance – 6 for market leading performance).

Sustainability Criteria

NABERS measures the environmental performance of buildings across the following impact areas:
– Energy efficiency
– Water usage
– Waste management
– Indoor environment quality
