Objectives of this rapid review The energy usage of a home is often an important factor for people when considering renting or buying. Using an energy performance rating is one way to show how “energy hungry” a home could be. In some countries, it is mandatory for the seller to obtain, and disclose, a home’s energy rating. For countries in the European Union, this has been the case for 10 years. In the ACT a disclosure scheme has been operating for 20 years.
