The NABERS Water Rating system measures the water consumption of office buildings on a scale from one to six stars. A one-star rating indicates the least efficient performance, while six stars reflect market-leading efficiency. Currently, the average rating in the market is around two and a half stars, highlighting room for improvement in water conservation.
Using the NABERS Water Rating, building owners can benchmark their water usage against others. This tool helps identify areas for improvement, aiming for a higher star rating and better sustainability.
