Energy Performance Certificates

Last updated: 24 March 2021

Since November 2006 all new homes and buildings for sale must undergo an energy performance evaluation (an energy performance diagnostic, or DPE), and receive an energy performance certificate. The certificate indicates both the level of energy consumption and the greenhouse gas (GHG) emission level, on a scale of A to G, with G being least efficient and highest GHG emissions. The diagnostic must be accompanied with recommendations on improving the buildings energy efficiency.


As of 1 July 2007, the diagnostic and certificates must also be provided for rentals, and is to be provided for all new construction where the buidling permit was submitted after 1 July 2007. Since 2 January 2008, the DPE has been introduced for all public buildings, and public display of the certificate is mandatory. The certificates differ from those for residential buildings, and three different categories of certificates are provided based on the buildings function (hospital, offices, educational institution, etc.).
