The performance scores use generally a scale ranging from 0 to 100 or 1 to 5 stars. The value of score is based on the comparison made between the rated house and a reference house that meets a desired energy code or standards.A rating of 50 indicates average energy performance, while a rating of 75 or more indicates best performance.
The Home Energy Rating is an American estimated measurement of a home's energy efficiency based on normalized modified end-use loads (nMEULs). [1] In the United States, the Residential Energy Services Network (RESNET) is responsible for creation and maintenance of the RESNET Mortgage Industry National Home Energy Rating Standards (MINHERS), a proprietary system of standards, [2] which includes ...
Green building in South Africa is overseen by The Green Building Council of South Africa [1] (launched 2007) which has developed Green Star SA rating tools, based on those developed by the Green Building Council of Australia [2] tools, to provide the property industry with an objective measurement for green buildings and to recognize and reward environmental leadership in the property industry.

Energy performance certificates (EPCs) are a rating scheme to summarise the energy efficiency of buildings. [4] [5] The building is given a rating between A (Very efficient) - G (Inefficient). The EPC will also include tips about the most cost-effective ways to improve the home energy rating. Energy performance certificates are used in many ...
