What are Display Energy Certificates (DEC’s)?

A DEC shows the energy performance of a building, based on actual energy consumption as recorded over 12 months within the validity period of the DEC (the operational rating).

The rating indicates the annual level of carbon dioxide emissions emanating from the building. This is displayed on a scale from best to worst rating or A to G respectively.

The main purpose of their introduction was to raise public awareness of energy use and to inform visitors to public buildings about the building’s energy use.

What is the legal requirement?

From 9 July 2015, a DEC has been required for all buildings occupied by a public authority where the total useful floor area of the building exceeds 250m² and where the public are frequent visitors.

In order for the building to have a required DEC, it must also:
- Have a roof and walls.
- Use energy to condition the indoor climate, such as with fixed heating, mechanical ventilation or air conditioning services. This can include the whole of the building or part of it, if altered or designed to be used separately.
