Energy-intensive building

General information

Managed by LOGIREM, the residence Le Provence is a set of 122 apartments spread over 3 buildings, built in 1972.

Because of its energy label D and its aging equipments, the rehabilitation of this housing complex was considered as a priority. Respecting its sustainable development policy, the social landlord wished to have a comprehensive approach to promote occupant comfort, reduce rental costs and control energy consumption.

The operations undertaken by the landlord are designed to achieve the minimum C + label. Through various financial aid is an ambitious project that was launched with the aim of reaching a primary energy consumption by 40 kWhep / m² / year, a level corresponding to the "factor 4" covered by ADEME.

Sustainable development approach of the project owner

Each residence managed by Logirem has a technical state record with an overall score. Because of its energy label D and its aging equipment, Le Provence was identified as a priority residence and a thermal audit was performed. Aiming first thermal objectives, the owner nevertheless wished to have a comprehensive approach. Various aids have helped make it an exemplary rehabilitation.

Architectural description

The architect wanted to provide a simple and modern response. To settle with the old concrete facade,the coatings colors were chosen in harmony with the tone of the neighborhood (wet sand).
Silkscreen printed and dune color resin panels, affixed on the length of facade, are providing a contemporary touch. On balconies, vertical guard rails were projecting a negative image. They were replaced by modern guard rails with opalescent glass, that promote privacy and allows light to penetrate.
