How are BEEC ratings calculated?
NABERS Energy star ratings:
These ratings are compared to benchmarks which are developed via actual building performance data. NABERS Energy star ratings through BEEC include a star rating as well as an additional rating based on the building’s annual levels of energy consumption and greenhouse gas emissions.
The NABERS rating for offices are a base building rating which includes areas that are managed by the building owner such as the building’s central services.
If a base building rating cannot be determined because the utility measure cannot differentiate between base building energy and tenancy energy use, an overall building rating may be used instead.
Tenancy Lighting Assessment (TLA):
A TLA is used to measure the Nominal Lighting Power Density of a building’s lighting system once a tenant leaves.
