DECs were introduced to raise public awareness of energy use and to inform visitors to public buildings about the energy use of a building. A DEC is an energy certificate that shows the operational energy rating of a public building, from A to G where A is very efficient and G is the least efficient. The operational rating is a numerical indicator of the actual annual carbon dioxide emissions from the building. DECs are based on the actual amount of metered energy used by the building over the last 12 months within the validity period of the DEC. The operational rating is calculated according to a methodology approved by the Secretary of State and carried out by an approved energy assessor using a specific software tool.
For more on energy assessors, see Practice Note: Energy performance certificates (EPCs)—energy assessor accreditation and energy assessments.
