Energy and Sustainability Hub

The Building Designers Association of Victoria (BDAV) has been appointed an Accrediting Organisation by Sustainability Victoria (SV) to accredit Thermal Performance Assessors (TPAs) - previously known as Energy Raters - who conduct assessments in Victoria.  This section of our website contains information for persons seeking accreditation.

In addition, the BDAV was advised by the Department of Climate Change and Energy Efficiency (DCCEE) on 30 September 2011 of our successful application to become a NatHERS Assessor Accrediting Organisation. In this capacity, the BDAV is able to accredit assessors to perform thermal performance NatHERS assessments under the Nationwide House Energy Rating Scheme. This means that the BDAV can now accredit thermal performance assessors who wish to also operate outside Victoria. This is subject to the BDAV also complying with the requirements of each State jurisdiction, as each State or Territory may have additional regulatory or policy requirements for NatHERS assessors to operate in their particular State or Territory. 

Persons wishing to enlist the services of an accredited TPA to have a thermal performance assessment conducted of their proposed dwelling design should visit the Find a Thermal Performance Assessor section at this website.

Thermal Performance Assessors

Thermal Performance Assessors (TPAs) conduct residential building thermal performance assessments.

Residential building thermal performance assessment is required for all proposed residential construction under current legislation, and measures the thermal performance of a proposed dwelling design.
