Project Summary

Description

This installation was designed due to an environmental wish of the public sector housing office and to decrease the yearly energy cost of hot tap water of this multi-family-house building. This building was built facing East in the beginning of the seventies and consists of 99 dwellings shared on 10 floors. The CSTS was achieved to supply the most part of hot tap water heating of the whole building.

Mr. Dunez, in charge of the technical services for the departmental office:

„Solar energy was a great opportunity to be invested in the green house gases reduction. We would show that a social office is able to be involved in Earth safeguard and protection. For us, we thought that interest in new technologies was linked with the city harmonious development.“
