The thermal renovation project of the Stendhal residence in Mérignac built in 1984 and comprising 61 collective housing units (3 buildings) is part of the overall renovation process. The objective of the thermal renovation of the Stendhal 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 114,55 kWhep/m².an (the energy label C) which could represent a gain of 170,99 kWhep/m².an.
