Description of Measure and Categorization

The territory's main social landlord, Advivo, has been engaged for several years in a major program to renovate its energy-intensive housing stock.

After the residences l'Isle 1, St Martin 1, Malissol 1, 2 and 3, Le Mas Charlemagne, it is now in the city centre of Vienne that the Office is carrying out a large-scale rehabilitation operation, the "Champ de Mars" residence. This project concerns 274 rental units, spread over 6 buildings. Work began in September 2016 and was completed in the summer of 2018.

In addition to improving the housing and outdoor spaces, one of the main objectives of this rehabilitation was to improve the energy performance of the residence. The work initiated made it possible to reduce the energy label of the buildings, which were initially classified as energy class E, to class B. This performance was achieved in particular through the replacement of external joinery, the replacement of water columns, the renovation of the thermal insulation, the waterproofing of the flat roof, the installation of individual low consumption gas boilers, etc.

This rehabilitation made it possible to obtain a consequent improvement in the energy performance of the residence, and thus the reduction of its environmental impact. It also permitted to considerably reduce the energy bill of the tenants: according to the estimates of the engineering and design department, the heating and domestic hot water charges was reduced by approximately 60%.

The operation is certified BBC Effinergie Rénovation (Low Consumption Building) and complies with the building environmental quality standard for the Auvergne-Rhône-Alpes region.

Area: Municipal Buildings & Facilities




The renovations benefited from a 2 million euro grant out of the 13 million euro investment. Among the grants: 

- PAM eco-loan in very significant proportions due to the very high energy ambition of the operation

- WFP from EIB resources fixed rate

- WFP Resource-Based Booklet A

- Subsidised equity loan by Caisse des Dépôts et Action Logements.
