Cité Perrache was designed by Jean Marin and Victor-Adrien Robert during the French hygiene movement. Built in 1934 by Grand Lyon Habitat, the Perrache low-cost housing project featured a large social housing development and a bath and shower building to foster the health of its residents. The entire ensemble is listed as a “Remarkable 20th Century Heritage Site” by the Regional Cultural Affairs Directorate (DRAC). A notable design feature are its three-part corner windows, which were very avant-garde at the time.
RENOVATION FOR ENERGY EFFICIENCY
Cité Perrache has been connected to the wood-fired district heating system (using biomass). The heating and hot water production systems have been standardised. Previously, 80% of the flats at Cité Perrache were heated with gas, and 20% were heated with electricity.
The energy renovation project has divided the apartments’ energy consumption by 6, resulting in a 40% decrease in the tenants’ energy bills.
SUPPORT FROM THE EUROPEAN COMMISSION AND THE JAPANESE AGENCY NEDO
The renovation of Cité Perrache was supported by the Lyon Smart Community programme. It also received the support of the European Commission as part of the H2020 Smarter Together programme, as an innovative, exemplary operation concerning “Health, Demographic Change and Wellbeing” and “Secure, Clean and Efficient Energy”. Finally, it is supported by the French government under the national Ecocité programme, and by Métropole de Lyon.
