Anenergy performance certificate (EPC) is arating scheme to summarise theenergy efficiency of buildings or devices.[1][2]
In the European Union, EPCs are regulated byEnergy Performance of Buildings Directive 2010.
EPCs are mandatory when buying or selling property.[3]
Energy performance certificates (EPCs) are arating scheme to summarise theenergy 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 Star (trademarkedENERGY STAR) is a program run by theU.S. Environmental Protection Agency (EPA) andU.S. Department of Energy (DOE) that promotes energy efficiency.[6] The program provides information on the energy consumption of products and devices using different standardized methods. The Energy Star label[7] is found on more than 75 different certified product categories, homes, commercial buildings, and industrial plants. In the United States, the Energy Star label is also shown on the Energy Guide appliance label of qualifying products.
