DEC

Display Energy Certificates

Display Energy Certificates (DECs) show the actual energy usage of a building, including its Operational Rating, and help the public see the energy efficiency of a building based on recorded energy consumption from gas, electricity, and other meters.

What is a DEC?

The requirement for Display Energy Certificates came into effect on 1 October 2008. A DEC shows the actual energy usage of a building and provides an Operational Rating based on metered energy consumption.

When is a DEC required?

Display Energy Certificates are required for buildings with a total useful floor area over 1,000m² that are occupied by a public authority or institution providing a public service to a large number of people.

The DEC is valid for one year, while the accompanying Advisory Report is valid for seven years.

What does a DEC include?

A DEC must be clearly displayed at all times and be visible to the public. It is always accompanied by an Advisory Report listing cost-effective measures to improve the building’s energy rating.
