Project Summary

Description

The specialised reception centre of Saignon, intended to physically handicapped persons, is an example of a high environmental quality process. This building was designed according to bioclimatic structure, especially with solar structure and was built on one floor to respect handicapped persons’ functionality. It concerns the creation of 21 beds shared out in three life units. This operation has received the first price of the architecture national contest “Solar housing, housing of today 2002” in the category “tertiary buildings”.
The CSTS was designed to produce hot tap water and to preheat water for the balneotherapy department.

Summary of experiences / Notices to the project performance:

This building was designed according to environmental and bioclimatic approach and, logically, CSTS has been integrated for hot tap water production.

A global project has been realised with an architect contest and a commission was created for the definitive project elaboration and to draft the contract in order to choose companies.

The CSTS perfectly running and provides 60 % of hot tap water needs of the building, as determined during the feasibility study.
