The energy labeling scheme for buildings derives from the directive on the energy performance of buildings (EPBD). The Energy Performing Certificate (EPC) shows the energy condition of the property and consist of an energy label and an energy plan. EPCs are prepared for new buildings and existing buildings that are sold, rented out or transferred.
For publicly owned buildings over 250 m2 the EPC must be reviewed regularly every ten years. Furthermore all large buildings over 600 m2 which are frequently visited by the public must display a valid EPC in a prominent place clearly visible to the public. Buildings are labelled from A to G, A covering low-energy consumption buildings.
