What is a Display Energy Certificate?
A Display Energy Certificate shows the actual energy usage of a public building over the past 12 months. It must be clearly displayed in a prominent location to inform the public how energy efficient the building is. DECs are a legal requirement for many publicly funded buildings over 250 square metres and include:
• A–G energy efficiency rating
• Annual energy consumption and carbon emissions
• Clear recommendations to improve energy usage
You can read more about DEC regulations on the UK Government’s website.
