Public buildings including schools over 250m2 must display a Display Energy Certificate prominently at all times. DECs are designed to promote the improvement of energy performance of buildings. The certificate looks similar to energy labels provided on electrical appliances such as fridges or freezers- it uses a similar scale for energy efficiency, i.e. A-G with A being the most efficient and G the least. A new DEC must be produced every year and an advisory report every 7 years. These services can be purchased from ECCU.
