Project Summary

Description

In the sustainable development framework, for service charges control and energy management, the OPAC 75 has chosen to develop solar thermal energy. This desire comes within an energy control and a renewable energy development plan for the reduction of greenhouse gases. This project was done to renew a 1984 existing solar thermal system stopped few years ago. This site is composed of different level buildings seved by 6 stairwells. The installation provides hot tap water production for the dwellings.

Mr. Reignier, in charge of the maintenance department for the OPAC 75:
The OPAC 75 has chosen to develop solar thermal energy for the reduction of greenhouse gases and for service charges control and energy management. In 2006, they expect to install about 3,000 square meters of collectors.
