The EPB certificate (energy performance of buildings) is the energy ID card of a building. Like the label on household electrical appliances, it contains a classification scale from A (very energy saving) to G (very energy intensive).
The EPB certificate is compulsory for all buildings that are to be sold or rented. It is drawn up by an independent expert after an in-depth technical examination of the premises.
The official document certifying to the energy performance of the building is valid for ten years if no alterations are made to the energy properties of the building.
Since 2011, all homes (irrespective of the surface area) and all offices of more than 500 m2 in the Brussels-Capital Region have to have an EPB certificate before they can be put up for rent or sale.
The expert trained and approved by Bruxelles Environnement/Leefmilieu Brussel (website in French - architect, civil engineer, industrial engineer or bio-engineer) uses a calculation method that takes account of all the energy that enters and leaves the building:
On the basis of these properties, the building is then classified on a scale from A (very energy-saving building) to G (very energy-intensive building), according to the same principle as that applied for the energy labels on household electrical goods.
The certificate is passed on within ten working days of the certifier’s visit. It is valid for ten years, unless the energy properties of the building are altered (boiler replaced, for example). In this case, it has to be updated before any further real estate transactions can be carried out.
