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 homethe construction of its roof, walls, windows and floorthe 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. |
