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 a Recommendation Report (RR), which outlines how the organisation can reduce their energy consumption.
A DEC is required when
- If the building is frequently visited by the public.
- If the building has a total useful floor area of over 250m2
- If occupied by a local authority or any public used building.
- Augment Awareness of Energy Use.
- Improve Corporate Social Responsibility
- Avoiding Fines.
