Project Summary

Description

The Cimade is an association created in 1939 to accommodate foreigners on regularization waiting. This reception centre was built for 70 persons (about 40 adults and 30 children) is an old building of 668 sqm (heated surface) of the 50’s, composed of two floors and 32 rooms from 12 sqm to 27 sqm.

In order to decrease the cost of hot tap water needs, but also to participate to the environmental protection, the owner hopes to use solar energy for hot tap water production.

The CSTS is composed of 36 sqm of collectors linked to a solar tank of 2,500 litres.

Summary of experiences / Notices to the project performance:

In order to decrease the cost of hot tap water needs, but also to participate to the environmental protection, the owner hopes to use solar energy for hot tap water production. IZUBA, in contact with Emmaus Community, has engaged a feasibility study. After having found financing for this project with ADEME / Languedoc-Roussillon Regional Council subsidies, building activities started at the beginning of 2003 and CSTS operates since April 2003.
