Energy transition

Cities and municipalities have a crucial role to play in the energy transition. After all a substantial part of our energy use goes to the urban environment. With "zet je woning op de kaart", an online questionnaire, citizens can discover free of charge how sustainable their home is. The data generated, are gathered and managed in the City Portal Platform of EnergyVille and VITO, an interactive platform, particularly interesting to implement the renovation policy of your municipality and visualize opportunities for collective renovations. Furthermore, the City Portal platform is offered free of charge by Fluvius, now known as Eandis and Infrax, to cities and municipalities.

Plan, implement and monitor renovation actions

How does it work? The data collection goes via the website ‘zetjewoningopdekaart’. Citizens fill in a short questionnaire about their home and discover in four simple steps whether or not their energy use is above average or not. The data is collected in the City Portal Platform which is offered free of charge to cities and municipalities.

What does the City Portal Platform have to offer for cities and municipalities?

  • The platform provides a better insight into the renovation potential of the building in your city or municipality. This can both be done on the level of individual houses as on static sectors or districts.
  • Insight is given in the state of the buildings in the city or municipality: both residential, commercial or mixed use.
  • By means of the tool specific interests in improvement measures can be visualized. Who is interested in which renovation? Where do they live? Can these renovations be bundled? By using handy filers it can for example be shown who is interested in rooftop insulation. This way specific group purchases can be organised.
  • In the future it will also become possible to use the tool to monitor the renovation actions performed.
