Residential Building Thermal Performance
A Building Thermal Performance Assessment also known as a House Energy Rating evaluates
the thermal efficiency of a new house design. In other words, it measures the home's
ability to stay naturally cool in summer and warm in winter.
The Building Code of Australia (BCA) Part 2.6 is the overall regulation mandating
Building Thermal Performance Assessments of residential buildings. The BCA is applicable
in all states except NSW.
In addition to BCA requirements, most state and territory governments have schemes
which specify the thermal performance benchmarks to be achieved and the assessment
procedures to be followed. See Regulating Sustainability for
detailed information on the environmental regulation applicable in your area.
When you need an Accredited Assessor
The Building Code of Australia (BCA) requires that Local Building Approval Authorities
(Building Surveyors at Local Councils) obtain evidence that a design meets the
'Performance Requirements' or 'Deemed to Satisfy Provisions' of the Energy Efficiency
sections of the BCA. This evidence may be in the form of a certificate from an 'appropriately
qualified person'.
ABSA has developed a complete Accreditation Scheme that regulates the practice of
its Assessors that conduct Simulation ratings for the 'Performance Requirements' of
the BCA to provide professionals that are appropriately qualified for this role. ABSA
Accredited Assessors must be engaged to generate a Building Thermal Performance Assessment
under some State regulatory schemes. ABSA has extensive accreditation and Quality
Assurance procedures for assessors, to ensure that consumers and regulators can be
confident in receiving a high standard of professional service. Assessors are also
backed by professional indemnity insurance.
ABSA Assessors provide services in all states and territories and can advise you on
the specific requirements for your area. Go to Find an
Assessor to locate an assessor near you.
Alternatively, you can contact the regulator responsible for your state's requirements
to find out more. These are listed on the Regulating Sustainability page.
