What is an EPC?
An EPC is a document which states the energy efficiency of a building based on the standardised way that the building is used.
Carbon dioxide (CO2) ratings are shown in bandings from A to G, with A being the least polluting. The number in brackets refers to CO2 emissions in terms of kg/m2 of floor area per year.
Since 4th January 2009, every new sale or letting requires that the building has an Energy Performance Certificate (EPC) if larger that 50 sq metres.
Why do we have EPCs?
They are required under EU law by the Energy Performance of Buildings Directive (EPBD). Each member state of the EU is responsible for implementing the directive.The Scottish Government via Scottish Building Standards (SBS) is responsible for the implementation of the directive.
The main focus of the certificate is the amount of CO2 which is estimated to be released from the building. The performance of the building is benchmarked against current building standards and recommended cost effective improvements. It also allows prospective owners and tenants to compare the performance with similar types of buildings.
The certificate must be fixed to the building and will be valid for a period of 10 years.
Which buildings require an EPC?
Generally, all public buildings over 1000m² will need to display an EPC, even if they are not being sold or leased. Examples include colleges, community centres, libraries, hospitals, benefit offices and crematoria. Exemptions to the requirement for an EPC include stand alone buildings less than 50m² , e.g. sheds and summer houses.
