2023年6月15日 · When assessing the energy efficiency of a domestic building, two key ratings will be published: the Energy Performance Certificate (EPC) rating and the Energy Impact Rating (EIR). These ratings provide valuable information about a building’s energy consumption, carbon emissions, and potential for improvement.

2024年12月4日 · There is also an emissions metric on the domestic EPC, called the “Environmental Impact Rating” (EIR) (see Figure 2). The EIR is calculated much like the EER, with a numerical scale converted ...

2024年12月4日 · EPC metrics should provide clear benchmarks of performance that can be used to aid decision making, set policy targets and establish regulatory requirements, such as minimum energy efficiency...

Environmental Impact Rating (EIR) The environmental impact rating is a measure of a home’s impact on the environment in terms of carbon dioxide (CO2) emissions....

buildings. The rating on the EPC which estimates the CO 2 emissions is the Environmental Impact Rating (EIR), which is to be found on the last page of the EPC. Many members states in the EU, where the EPC originated, use the EIR as their headline rating. At present we have a mismatch between the main policy aim (decarbonisation)

EPCs currently include two ratings: the Energy Efficiency Rating (EER) and the Environmental Impact Rating (EIR). The EER is the main metric used for policy delivery. Energy Efficiency Rating. The EER is a measure of energy costs per square metre per year (it is not a direct measure of energy efficiency). Environmental Impact Rating.

2025年1月30日 · Energy Performance Certificates for domestic properties show an Energy Efficiency Rating (EER) based on estimated fuel costs and an Environmental Impact Rating (EIR) based on CO2 emissions.

EPCs are valid for 10 up to years from the date of issue. You can check the EPC of your property on www.gov.uk/find-energy-certificate. An EIR is a measure of a homes impact on the Environment in terms of Carbon Dioxide (CO2) emissions. It tells you how much of an impact your home is having on the environment.

2019年12月19日 · Domestic EPCs display an Energy Efficiency Rating (EER) and an Environmental Impact Rating (EIR). The EER is rated in terms of energy costs, while the EIR is rated in terms of carbon emissions. Domestic EPC s also have numerical ratings, with a higher number suggesting greater energy efficiency.

Environmental Impact Rating (EIR) − based on carbon emissions. The above Energy Ratings are determined mathematically by the software which also includes the EPC report. Energy efficient improvements in the form of recommendations from the DEA are also included in the EPC report to each recommendation and itemised together with a value that ...
