Case Studies
Résidence Colbert
Colombes, France
Code: OP08
Summary
1970 built residential uilding in the dense centre of Colombes, a western suburb of Paris.
Original situation
The retrofitting process started in 2013, and the project consists of three buildings using the same construction methods (A: 2529 m2, B: 1523 m2, C: 1768 m2). All three buildings were retroffitted together. The buildings were using approximately 250 kWh/m2 of oil heating.
Renovation approach
The main retrofit steps were finished in 2020 after a 2-year delay. Some finishing touches are still being undertaken in 2022.
Modernisation proposal
Global prefabricated retrofit. The facade uses the "Panobloc" pre-fab facade system.
