INFINITE Case Study: France

About this case

«Les Doucettes» residence in Garges-Lès-Gonesse consists of two similar buildings, that might be refurbished together. Built in 1976, they have been classified as energetic class D. The buildings are composed of 71 dwellings. STRUCTURE: assembled deactivated concrete panels.

The challenge

  • Very large areas to be renovated: how much will investors be willing to pay for new technologies?
  • INFINITE will be tested only on one of the buildings. The other one will be an interesting challenge and test bench for the solutions developed by the project. Will the owner decide (and be able) to apply the same approach?
  • Aesthetics is considered very important by the Municipality. The design must fit with the surroundings.

The INFINITE project will implement the all-industrialised BIPV kit on the main façade and roof. The BIST kit will be mounted on the southern façade, while the rest of the façades and roof will host the passive kit and eventually the green kit. The balconies will be transformed into loggias. The smart windows integrating shading and electrochromic systems will be installed on the whole building. The distribution kit will provide fresh air, air-based space heating and possibly cooling. During the project, the partners will evaluate the possibility to expand the area of INFINITE retrofit to other building.
