Energy performance certificates have been required since 6 April 2008 when commercial buildings are built, sold or rented.
An EPC summarises information about the potential energy performance of a building, its fabric and the building services utilised. The certificate shows the building owner/occupier the Asset Rating and where it fits on a scale of A through to G, based on the CO2 emissions released by the building. As part of the certificate a rating of A to G is also generated for a "typical" new and existing building for comparison with the rating generated for the subject building.
An EPC will be accompanied by a Recommendation Report highlighting measures which, if adopted, have the potential to reduce CO2 emissions and energy costs associated with the building. The certificate will remain valid for ten years unless the building is modified by means of an extension or any major changes to the building services.
edc have trained engineers experienced in SBEM (Simplified Building Energy Model) analysis.
As the actual services and internal layout are key elements in the calculations of an EPC older commercial property will require a site survey to ensure accurate up-to-date data is utilised.
