Project Summary

Description

The 192 dwellings of the five buildings of Canonniers in Strasbourg belong to the locative stock of CUS Habitat, the urban community of Strasbourg public housing office. The office has decided to invest in sustainable development and to involve its tenants in this approach. After a first conclusive operation in 2003 with the installation in Ostwald of 406 sqm of collectors, the CUS Habitat has decided to launch a global tender enquiry on its possible equipped buildings.
300 sqm of collectors fixed on the building containing the heater, and allow covering 35 % of hot water consumptions. Solar storage is of 12 cbm and the back-up is provided by central natural gas boilers.

Mr. Palermiti, CUS Habitat / Building site coordinator:

„A global tender enquiry of the CUS Habitat has been launched on its properties that can be equipped. It represents more than 5,000 dwellings with more than 7,000 sqm of solar collectors that will be installed at the end of the year 2007.“

Summary

The CSTS was composed of 300 sqm of flat plate collectors installed on flat roofs of the building where is located heaters. They are facing south with an inclination of 45°. They are linked to two storage tanks that represent 14 cbm of solar storage and back up is provided by a central heating with natural gas.

Development & experiences

Summary of experiences / Notices to the project performance

The hotel owner has chosen to answer to its clientele environmental concerns, especially the Northern-European one and, also, tour operators more and more sensitive by these processes. This hotel includes a CSTS since its creation date in 1981. In a sustainable development approach, the owners have decided to totally restore the CSTS for hot tap water production and swimming pool heating.

Summary of experiences / Notices to the project performance

In 2000, the CUS Habitat tenants were involved by the “Take by storm to service charges” operation by giving propositions to decrease service charges and solar solution for hot tap water production has been accepted. Two markets have been proposed, one for the hydraulic and installation part specific to each project and one for solar materials for all the different solar projects planned in the framework of the global tender enquiries by the CUS Habitat.
