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 come within an energy control and a renewable energy development plan for the reduction of greenhouse gases.
This project was done to renew a 1982 existing solar thermal system. This installation groups together 13 buildings and provide hot tap water production of the dwellings. Hot tap water supplying is realised from twelve substations linked to the central heater.

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.“
