EPA Paris-Saclay, the Land Planning Public Authority for the Paris-Saclay urban area, is in charge of the development of one of a world class technology and innovation cluster. It believes that such an urban development must be in advance with respect to environmental issues, using the most innovative technologies to fulfill its high energetic and environmental objectives, in line with the COP21 global and national objectives. Its energetic strategy reflects this ambition.
Paris Saclay District Heating and Cooling network which is one of the most innovative DHC grids in Europe, is the cornerstone of this energy strategy.

5GDHC Principles
Ambiant LOOP
Carrying thermal energy from the Energy Centre to the decentralized plant (“SSTI”), and allowing heat and cold exchanges between building clusters.
DECENTRALIZED HEAT AND COLD NETWORK
Connecting decentralized heat and cold plants to local customers. These heat and cold plants (“SSTI”), located in the basement of major buildings of the urban campus, host the heat pumps supplying simultaneaous heat and cold.
GEOTHERMAL WELLS
Two 700-meter-deep wells into the Albien aquifer are necessary : One pumping geothermal water the other returning it back to the Albien aquifer after extracting its heat. The Albien aquifer is a eep 30°C-water field located under the Paris region. It dates back to -145 millions year.
