Thermal performance assessment evaluates the thermal performance of the building envelope elements (namely, walls, floors, roof) based on the site’s climatic data and building design to determine how thermally comfortable a dwelling will be throughout the year without mechanical heating or cooling. Performance is dependent on:
- thermal mass
- ventilation, and
A Residential Thermal Performance Assessor is an individual who is qualified and accredited by an Accrediting Organisation to use a second generation house energy rating software program to determine the thermal performance of residential buildings, as specified by the Building Commission Practice Note 2011-55, and the Building Code of Australia, as amended from time to time.
