## Short definition

Australia's National Australian Built Environment Rating System.

## Full definition

Government-backed rating from 1 to 6 stars on energy, water, indoor environment quality, and waste. Mandatory disclosure for buildings over 1,000 sqm at lease and sale. Trophy benchmark is NABERS Energy 5.5+. The most rigorous operational rating regime globally.

## Example

Salesforce Tower Sydney targets NABERS Energy 5.5.

## Why this matters for Class A leasing

NABERS is part of the esg vocabulary that institutional [Class A](/glossary/class-a) occupiers, landlords, and advisers use across APAC markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks the APAC definition alongside the global standard so [cross-border](/topics/cross-border-expansion) occupiers can translate quickly.
