The project presented by the promoter aims at the energy rehabilitation of 177 social housing units at the residence “La Justice” in Cergy. The project involves the rehabilitation of two buildings (Building A — 125 dwellings — and Building B — 52 dwellings). The residence of Cergy Justice Mauve is a building complex completed in 1978 whose right-of-way consists of 3 buildings built of reinforced concrete on a level of cellars, with roofs terraces and facade covering coated and slates at the top. Although the overall project provides for the requalification of family housing, home dwellings and outdoor spaces, the holder’s request for subsidy concerns only the rehabilitation of the 177 family housing units.
