The thermal renovation project of the Clos Monfort residence built in 1989 and comprising 90 collective housing (11 buildings) is part of the overall renovation process. The objective of the thermal renovation of the Clos Monfort residence is to increase the energy performance of the residence in order to improve the comforts of tenants. In terms of energy performance, this project aims, after work, to the primary energy coefficient of 130,31 kWhep/m².an (the energy label C) which could represent a gain of 135,54 kWhep/m².an.
