Energy Rating

What is House Energy Rating?

It is an index of a building's thermal performance (i.e. heating and cooling requirements) for residential homes in Australia. Home energy ratings can be used for either existing homes or new homes. A home energy rating of an existing home allows a homeowner to receive a report listing options for upgrading a home's energy efficiency. The homeowners may then use the report to determine the most effective ways in which to upgrade the home's energy efficiency. A home energy rating of a new home allows buyers to compare the energy efficiency of homes they are considering buying, as well as specifying the insulation ratings that need to be used.

What is rated?

A dwelling can be rated before or after it is built. The rating depends on:

  • the layout of the home
  • the construction of its roof, walls, windows and floor
  • the orientation of windows and shading to the sun's path and local breezes how well these suit the local climate.

What the stars mean?

  • Zero stars means the building shell does practically nothing to reduce the discomfort of hot or cold weather.
  • A 5 star rating indicates good, but not outstanding, thermal performance.
  • Occupants of a 10 star home are unlikely to need any artificial cooling or heating.
