DECC Display Energy Certificates
This series brings together all documents relating to DECC Display Energy Certificates
Public buildings are required to display a Display Energy Certificate (full version attached), which represents actual energy use. The rating is calculated based on historical energy use throughout the previous 12 months and is represented as a letter between A and G, with A being the most efficient. It is also given a numerical score, which represents comparative energy efficiency. A typical score for a building like 3 Whitehall Place would be 100, which is the boundary between a D and an E.
