Star Rating

The assessment process involves use of approved software to model the design and produce a star rating certificate. Compliance is achieved if a minimum of 6 stars is reached.

Deemed-to-Satisfy (DTS)

The proposed building’s construction is compared to the standards prescribed in the Building Code of Australia (BCA) Volume 2 to determine a strict pass or fail result.


Verification Using Reference Building (VURB)

Essentially this method combines DTS and thermal modelling methods. Using a theoretical reference building, which is a building modelled with DTS elemental provisions, an annual energy consumption is determined and set as a benchmark. The annual energy consumption for the proposed building (including client specifications) is then calculated using the same thermal modelling software along with a set of fixed parameters. Compliance is verified if the proposed building has an annual energy consumption equal to or less than that of the reference building.


The National Construction Code (NCC) requires all new buildings and extensions to be energy efficient.  If you’re planning a new development or extension to an existing building you will need a certificate to certify it complies with the Code.

ESD can provide a commercial energy efficiency assessment to assess if the building conforms to Section J of the NCC.  We assess all classes of buildings including multi-storey units, schools, shopping centres, warehouses, airports, retail and office tenancies.

Deemed-to-Satisfy (DTS)

The most common assessment is a Deemed-to-Satisfy report for commercial buildings that involves reviewing each applicable performance requirement from Section J of he Building Code of Australia (BCA) Volume 1 and providing a certificate that indicates how compliance is achieved for each relevant building element.
