The headquarters of Crédit Agricole du Nord Est in Reims extends over almost 12000 m2. Its refurbishment includes many technical lots totalling 5.5 million Euros gross (electricity, strong & weak currents, heating, ventilation). The prime contractor role has been entrusted to Cap Ingelec. The target gain in energy performance is 65% (from 178kWhap/m2.year to 64kWhep/m2.year*). This objective is achieved through renovating the buildings and installing high performance technical equipment (e.g.
heat-cooling pumps, back-up gas boiler). The works advance in two phases to ensure uninterrupted operation. The delivery of the completed Directors' floor as the first round necessitates the anticipated replacement of all the production systems.
