Government guidelines state that public authorities must have a DEC for a building if it meets the following requirements:
• It’s at least partially occupied by a public authority, examples being a council, leisure centre, college, NHS trust
• It has a total floor area of over 250 square meters
• It’s frequently visited by the public
To comply with government guidelines, buildings which meet the above requirements must display a valid DEC and a valid Advisory Report (AR), or face a total fine of £1,500. A DEC is valid for one year and promotes good energy management within organisations based in public buildings.
It shows how much energy is being used in the building and provides a rating based on how much energy has been used over the previous 12 months for similar buildings. The ratings range from A-G (A being the most energy efficient) and indicate to your service users and stakeholders the progress you are making towards energy efficiency.
