NABERS (National Australian Built Environment Rating System) is a national rating system that measures the environmental performance of existing buildings. For commercial property owners, a strong NABERS rating can significantly impact property value and tenant attraction.
How NABERS Works
NABERS rates buildings on a scale of 1 to 6 stars across four categories: energy, water, waste, and indoor environment. The rating is based on 12 months of actual measured performance data, not theoretical design.
Why NABERS Matters
The Commercial Building Disclosure (CBD) program requires most office buildings over 1,000 square metres to have a current NABERS energy rating when being sold or leased. Higher-rated buildings command premium rents and lower vacancy rates.
Improving Your NABERS Rating
Common improvement strategies include upgrading HVAC systems, improving BMS controls, LED lighting upgrades, optimising tenant sub-metering, and addressing building envelope issues like air leakage and insulation.
