BRGM is carrying out two opportunity studies on the Metropolises of Orléans and Strasbourg for the implementation of 5 th Generation District Heating and Cooling (5GDHC) grids. In Orléans, one considers supplying the extension of an economic activity zone with the 5GDHC powered by a combination of waste heat and shallow geothermal energy. A detailed energy model is being built in TRNSYS, and preliminary results related to the consumer stations are reported in this paper. In Strasbourg, the 5GDHC will supply new residential and tertiary buildings as well as a shopping centre by using the Rhine alluvial aquifer as the main energy source.
