Flemish houses now have a building passport

  • February 6, 2019

The Building passport is currently available for single-family homes from private individuals. For apartments or collective buildings, there is usually no building passport available yet.

The following government information is available:

  • general building information such as location and disposition
  • formatted EPCs or EPB declarations of the house and relevant energy information
  • the renewed EPC with renovation roadmap with cost estimation
  • soil data from the Soil Information Register (GIR)
  • solar map
  • environmental information: flood sensitivity, non-movable heritage, area destination plan
  • Roadmap: what to do when you (re) build, buy, sell or rent a house?

In time, the building passport will be extended with more information and functionalities:

  • house quality check tool
  • certificates of house quality such as the certificate of conformity, the technical report for house quality and the decisions regarding unsuitable and uninhabitable dwellings
  • possibility of requesting a soil certificate and additional useful soil information
  • building passport for houses owned by a company
  • possibility for the owner to share his building passport with third parties

You cannot see details of the renovation works that you carried out yourself in the building passport. In the future, you will be able to add and save documents regarding renovation yourself.

Building passport as a catalyst for the Renovation pact

In the Renovation Pact 2050, the Government of Flanders laid down the ambition to make all houses and apartments in Flanders as energy-efficient as a new building today. This would mean a reduction of at least eighty per cent in the greenhouse gas emissions by the residential sector. The building passport clarifies and simplifies the renovation process.

BE-REEL! conducts user tests and uses the housing card for the pilot and demonstration projects of its partner cities in the various segments of the housing market. Feedback rounds are organized with the various user groups. Besides the citizen, various service providers are also offered to assist the citizen during a renovation project. These lead to recommendations for the further development of the building passport.


Hands-on user tests are organized for the citizen, whereby the user-friendliness and the contents of the building passport were questioned at a number of test persons. In addition, each building passport user can always give feedback via a feedback button with questionnaire in the building passport. The first results of this questionnaire show a large general customer satisfaction and energy appears to be the most popular theme in the building passport.

Go for a top score!

The energy performance certificate (EPC) has been thoroughly renewed since 1 January 2019. This new EPC is still mandatory for houses and apartments that are offered for sale and for rent, and it now works with a label going from A + (being a house that produces more energy than it consumes) to F (a very energy-consuming house). This label allows the potential buyer or tenant to assess the energy performance of the house or apartment even faster and compares it more easily with other houses and apartments. This label is already available in the building passport today.

In addition, the new EPC presents the recommendations in a comprehensive, clear roadmap, supplemented with an average cost price estimation and technical information. This shows the potential buyer / tenant quickly and easily what still needs to be done to make the home energetically in order and what the order of magnitude of the corresponding cost.

The owner also finds this information in his building passport if he has such a new EPC.

EPC bannerThe label and the concise advice of the new EPC also offer opportunities for citizens who do not necessarily want to sell or rent. Through the new EPC everyone can check which energetic renovation works are needed to get a house or apartment an A-label. And anyone who has already undergone a renovation can find out which label his renovated house has obtained.

A good label is not only important for your energy bill and your comfort. It also plays a role in the value of your home. Based on research conducted by KU Leuven on behalf of the Flemish Energy Agency, it appears that homes with a B-label have been sold eleven percent more expensive over the past 10 years than houses with an E-label. And while around 2005 the presence of single glazing led to a house that was on average four percent cheaper, by 2017 this has already increased to an average of seven percent cheaper. The reverse is noticeable for roof insulation: from 2005 to 2008 roof insulation led to a house that was on average 1.5 percent more expensive than average; this has already increased to an average of 4 per cent in 2017
