DISTRICT COOLING - Climespace - Paris - France

70 km of district cooling network in Paris

Concession company for the City of Paris since 1991, CLIMESPACE produces and distributes cold energy for air-conditioning. Over the last 18 years, INPAL Energie has supplied a large proportion of the 70 km long network installed in the drains or buried underground. The main "Centre" network extends over the 1st, 2nd, 7th, 8th, 9th and 16th arrondissements. "Bercy", a secondary independent network, is located in the 12th and 13th arrondissements. Most of this underground network is installed in the sewerage structures of the City of Paris or runs under the roads. 85% of the network can therefore be inspected. Regular and daily checks are performed on this fully-meshed, interconnected network. CLIMESPACE has entered a cycle where the new work phase is accompanied by a network operation ramp-up. In 2009, 1,860 metres of ND 500 were laid, Boulevard Saint Germain. The installers for this project were COFELY Installation and SADE.
