The thermal renovation and rehabilitation of the Maurice Thorez residence in Bègles concerns 510 housing units in 10 buildings. The thermal insulation of roof terraces and upper ground floor floors is reinforced and thermal insulation panels are applied to the facades of buildings. Elements of metal cladding or composite mineral dress dress this insulation from the outside and help to give a new image of the residence. From a label D or E, the dwellings are classified after work with a label B. To improve comfort, a VMC is set up with change of the vents of air and ventilation.
