Energy performance certificates

Energy performance certificates provide building owners, but also potential buyers or tenants, with reliable information on typical energy use, estimated energy costs, and recommendations for improvement. 

These certificates are an essential information tool, which indicates the energy performance of a building, taking into account

  • the building envelope, such as roof and floor insulation and windows

  • the efficiency of the building’s systems, in particular heating, cooling and domestic hot water

  • the use of renewable energy, for example via solar panels

With buildings responsible for 40% of energy use in the EU, they are a cornerstone of the EU’s policies to lower energy bills, fight energy poverty and increase health and comfort at home and at work.

What are the benefits?

The energy performance certificates help you estimate how much it will cost to keep the home or office warm in winter and cool in summer. It helps people make more informed decisions on buying or renting property, based on energy performance.

Buildings with higher ratings, close to A, often sell faster and for higher prices, because they are cheaper to run and more comfortable. 

Energy performance certificates based on the revised Energy Performance of Buildings Directive suggest potential improvements, big or small - like adding insulation or replacing the boiler - and estimate how much energy these upgrades could save you. They will also provide the contact information of the relevant one-stop shop for renovation advice.

An average A-class building typically consumes 10 times less energy than an average G-class building.

How to obtain an energy performance certificate?

Advertisements for buildings on sale or for rent must indicate the energy performance indicator and energy performance class. Prospective tenants or buyers have a right to see the building’s full energy performance certificate.

EU rules on energy performance 

The revised Energy Performance of Buildings Directive strengthens the energy performance certificates and ensures that they are comprehensive, comparable and of good quality across the EU. 

  • The energy performance classes go from A, which represents Zero-Emission Buildings, to G which represents the worst-performing buildings of the national stock. EU countries decide on the specific range of values of energy performance to be attributed to each class in their country. 

  • Energy performance certificates will also indicate the building’s estimated annual energy use, renewable energy produced on-site, greenhouse gas emissions, as well as a set of recommendations to improve the building’s energy performance.

  • The certificates were already mandatory for buildings that are constructed, sold, or rented, with exemptions possible, such as for religious, agricultural and temporary-use buildings. The revised directive includes also renewals of rental contracts and major renovations and improves the control mechanisms.

  • Energy performance certificates must be issued in a digital format and uploaded to national digital databases. Access is open to those with a legitimate interest, notably owners, tenants, building managers and financial institutions holding a mortgage for the building in question. 

  • Energy performance certificates should be affordable and EU countries must consider whether to provide financial support for vulnerable households.

  • The revised directive also introduces voluntary renovation passports, as tailored roadmaps to guide building owners in their renovations carried out in several steps. The energy performance certificates and renovation passports can be drawn up jointly, in which case the renovation passport will substitute the recommendations in the certificate.
