DECs

Display Energy Certificates (DECs) indicate the real energy usage of a building and its operational rating, helping the public see the energy efficiency of a building. This is calculated by examining the energy consumption of the property as recorded by the gas, electricity and other meters.

The DEC must be displayed at all times in a prominent place within the building and be clearly visible to the public. A DEC is always accompanied by an Advisory Report that lists cost effective measures to improve the energy rating of the building.

Currently Display Energy Certificates are only required for buildings that are occupied by a public authority or an institution providing a public service to a large number of persons with a total useable area greater than 1000m2. Display Energy Certificates are valid for one year. The accompanying Advisory Report is valid for 7 years.

In the future, the government has announced itsintention to consult on whether this requirement should include private sector buildings occupied by commercial organisations where large numbers of the public regularly visit the building.

Please contact our sales office if you require any information regarding DECs, the services that Enlighten Enviro offers or if you require a quotation from Enlighten Enviro to undertake a DEC.
