Welcome to our Display Energy Certificates page. The Energy Performance of Buildings Regulations introduced the requirement for Display Energy Certificates (DECs) in public buildings by 1st October 2008. From this date a DEC must be prominently displayed in non-domestic public buildings with a gross floor area over 1,000 m2 (this is the area measured from the internal face of your external walls).
In the context of these Regulations a public building is one occupied by public authorities or institutions providing public services to large numbers of persons e.g. central Government, local authority, NHS buildings etc. Buildings such as leisure centres, theatres and galleries providing services from public funds will also need a Display Energy Certificate. Recent changes have reduced the requirement to only those buildings which are frequently visited by members of the public, and useful guidance on this criteria is provided in the Communities website DEC FAQ section. Smaller buildings will also be ‘caught’ by the Regulations on a site where they have a combined floor area exceeding 1,000 m2 and are connected by a conditioned (heated, cooled or mechanically ventilated) space.
The Display Energy Certificate will convey the Operational Rating of the building, indicating its energy efficiency and CO2 emissions on a scale of A to G. The Operational Rating will indicate how well the building is being managed and operated. Display Energy Certificates are based on the building's energy consumption, but estimated consumption data from energy suppliers is acceptable during the initial implementation period.
What does a DEC look like?
A Display Energy Certificate conveys all the information necessary for the public to take a view on the building's energy performance, and most importantly it will include advice for improvement. An example DEC is shown above. Display Energy Certificates will be accompanied by an Advisory Report highlighting measures which, if adopted, have the potential to save energy and money. A DEC will remain valid for one year and the Advisory Report will remain valid for seven years.
Who can produce a DEC?
Display Energy Certificates and Advisory Reports can only be produced by a qualified and accredited non-domestic energy assessor. Our CIBSE Low Carbon Energy Assessor is fully accredited to produce your DECs and Advisory Reports. CIBSE's world-wide reputation for excellence gives you assurance of our professional competence.
