Energy for Offices

NABERS Energy measures the efficiency of an existing office building and rates its in-use performance. The energy rating works by comparing the energy consumption of a building against a set of benchmarks that have been developed using actual data.

Offices can be rated in three ways: Base Building, Tenancy and Whole Building ratings.

  • Base building ratings allow buildings to be rated based on their central services like heating, cooling systems and lifts.
  • Tenancy ratings enables energy used by the tenant to be rated, typically for lighting and power, plus special tenancy requirements for local a/c. 
  • Whole building ratings provide assessment of energy used by office tenancies and by Base Building services to lettable and common spaces.

To obtain a NABERS Energy rating you need an Accredited Assessor to undertake an assessment of your building.
