Eco-renovation of 64 dwellings — 1 to 11 rue de Franche County and 4 to 6 Impasse de la Route Romaine in Genlis The project promoter ORVITIS, OPH de Côte d’Or, undertakes eco-renovation works of 64 dwellings, on three buildings, rue de Franche County and Impasse de la Chemin Romaine in Genlis given the energy performance of the buildings getting worse and worse, and old components. The boiler room has recently been replaced, and this action should be supplemented with the treatment of building insulation.
