This large-scale project will benefit 743 households from a better energy ranking of their homes with a pass from the D or E label to the BBC level. The operation takes place in the city Esplanade in Strasbourg and concerns 12 buildings built in the years 1962-64 and 5 pavilions dating from the 1980s. The buildings require a complete renovation program. In addition to the energy efficiency work on the insulation of the building envelope, the replacement of exterior joinery, the modernisation of the heating and ventilation system, the programme includes work to improve the comfort of the dwellings, to secure and to beautify the common areas. The ERDF shall contribute to the financing of the energy efficiency component of the works.
