Display Energy Certificates (DEC)
DECs are a way of showing the operational energy efficiency rating of a building. The DEC must be displayed clearly in buildings occupied by public authorities and institutions that provide services to the public, have a floor area of over 1,000 metres squared and are frequently visited by the public. It must be updated every year.
Public authorities include central and local government, schools, courts and prisons. Institutions that provide services to the public include organisations that provide services paid for by the taxpayer.
The operational rating is a measurement of the energy efficiency of the building, on a scale from 'A' to 'G'. 'A' is the most efficient and 'G' is the least efficient.
The certificate also shows the operational ratings for the last three years. You can use these ratings to check whether the energy efficiency has improved or not.
