An Energy Performance Certificate (EPC) sets out the energy efficiency grade of a commercial building. Energy Performance Certificates (EPCs) are required when a commercial building over 50m2is built, sold or rented. There are two grades of buildings under the EPC requirements which relate to the complexity of the building being assessed and will affect the type of EPC assessor you will need.
EPCs are produced using standard methods and assumptions about energy use to enable the energy efficiency of buildings of the same type to be compared. They are valid for ten years but must be renewed if modifications to the property are made.
What an Energy Performance Certificate (EPC) contains:
The EPC has two parts - a graphic rating and a recommendations report.
The rating is calculated on the performance of the building and its building services (such as heating, lighting, air conditioning), rather than the appliances within it. This is known as an asset rating - that is, how energy efficient the building has been designed and modified. The certificate also gives an indicator of the potential rating of the building if all the cost-effective measures suggested in the recommendations are carried out. A building's rating will vary depending on the age, location, size and condition of the building, which are taken into account.
To produce an EPC the assessor will need information on the following:
If you need an Energy Performance Certificate for your building CIBSE certified Low Carbon Energy Assessors (LCEAs) can provide one.
CIBSE certified Low Carbon Energy Assessors (LCEAs) have undertaken additional training so that, not only are they able to provide you with an energy performance certificate, they can also provide tailored advice to help you cut the energy costs and carbon emissions in your buildings.
CIBSE certified LCEAs are not necessarily members of the CIBSE.
Energy Performance Certificates must be produced by a certified EPC energy assessor. To find a CIBSE Certification certified EPC energy assessor in your area search our Register of Low Carbon Energy Assessors.
