Environmental impact rating
Energy Performance of Buildings Certificates: glossary, originally published by the Ministry of Housing, Communities & Local Government in 2014, defines the environmental impact rating (EIR) as: ‘…a measure of a home’s impact on the environment in terms of carbon dioxide (CO2) emissions. The higher the rating the less impact it has on the environment. This rating is based on the performance of the building and its fixed services (such as heating and lighting). An EPC for a dwelling will show both the current emissions and potential emissions of a property.’
