General Information

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:

  • aspect
  • windows
  • thermal mass
  • insulation
  • ventilation, and
  • zoning.

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.
