Committed to an extensive energy rehabilitation program, CDC Habitat Social carries out ambitious work programmes to reduce the energy poverty of households occupying housing in social residences. The Watteau residence in Sarcelles, was built in 1961. It is included in the Urban Renewal Programme (NPNRU) as a rehabilitation. The operation concerns the first phase of works initiated from 2019 for three towers of the residence comprising 150 dwellings in total.
