EPCs for Commercial Buildings

2.1 What is an EPC and what does it mean?

The EPC looks broadly similar to the energy labels now provided with vehicles and many appliances. Its purpose is to indicate how energy efficient a building is. The certificate will provide an energy rating of the building from A to G, where A is very efficient and G is the least efficient. The better the rating, the more energy-efficient the building is, and the lower the fuel bills are likely to be. The energy performance of the building is shown as a Carbon Dioxide (CO²) based index.

Each energy rating is based on the characteristics of the building itself and its services (such as heating and lighting). Hence this type of rating is known as an asset rating.

The asset ratings will reflect considerations including the age and condition of the building. It is accompanied by a recommendation report, which provides recommendations on using the building more effectively, cost effective improvements to the building and other more expensive improvements which could enhance the building’s energy performance.
