NABERS provides four environmental rating tools - NABERS Energy, NABERS Water, NABERS Waste and NABERS Indoor Environment - to measure the actual operational performance of existing buildings and tenancies.
NABERS can be used to rate commercial offices, shopping centres, hotels and homes.
NABERS ratings for offices can be used to measure the performance of a tenancy, the base building or the whole building. The tenancy rating includes only the energy or resources that the tenant controls. A base building rating covers the performance of the building's central services and common areas, which are usually managed by the building owner.
A whole building rating covers both the tenanted spaces and the base building, and is typically used in an owner-occupied building, or where there is inadequate metering to obtain a base building or tenancy rating.
