Display Energy Certificates (DEC)
What is a Display Energy Certificate?
A Display Energy Certificate (DEC) shows the energy performance of a building, based on the operational rating, on a graphical scale from A (very efficient) to G (least efficient). A DEC must be accompanied by an advisory report which outlines how the organisation can reduce their energy consumption.
When are Display Energy Certificates required?
A DEC is required:
- If the building is a frequently visited public building
- If the building has a total floor area of over 250 m²
- If occupied by local authority or any public used building
For a building to fall within the requirement for a DEC it must:
- have a roof and walls; and
- use energy to condition the indoor climate. This is the case where the building has any of the following fixed services: heating, mechanical ventilation or air conditioning.
The penalty for failure to display a DEC is £500 and a further £1000 for failure to obtain an advisory report.
How long is a Display Energy Certificate valid for?
Where the building has a total useful floor area of more than 1,000 m², the DEC is valid for 12 months. The accompanying advisory report is valid for 7 years. Where the building has a total useful floor area of between 250 m² and 1000 m², the DEC and advisory report are valid for 10 years.
Why do I need a Display Energy Certificate?
DECs were introduced to help improve the energy efficiency of buildings and to inform visitors about a building’s energy usage.
The energy efficiency rating provided by the DEC allows Compliance365 to make recommendations to you that should improve your building’s energy efficiency.
