Display Energy Certificates and Advisory Reports are required for all public buildings with a floor area of over 1000m².
A Display Energy Certificate shows the energy performance of a building based on actual energy consumption as recorded annually over periods up to the last three years (the Operational Rating).
The Operational Rating is a numerical indicator of the actual annual carbon dioxide emissions from the building. The Operational Rating is based on the amount of energy consumed during the occupation of the building over a period of 12 months from meter readings.
This rating is shown on a scale from A to G, where A is the lowest CO2 emissions (best) and G is the highest CO2 emissions (worst).
Also shown are the Operational Ratings for the previous two years; this provides information on whether the energy performance of the building is improving or not.
A Display Energy Certificate is valid for one year and must be updated annually.
All of the Display Energy Certificates for Chesterfield Borough Council's eligible buildings are displayed on site but are also listed below.
