Underground networks of urban infrastructures channel fluids, water, sewage, air, mechanical and thermal vehicles, store resources of all kinds, and interact with the underground mean, which allows to preserve a moderate rate of intensity and temperature of the thermal energy that they store and transport, all of it very close to the potential users that these resources could serve as primary resources. It is the case of the Municipal Sports Center, CDM, of Moratalaz, an installation that gives sporting services to about 600,000 users per year and has equipment voraciously consumer of energy resources as it is, in our case, the indoor swimming-pool. The heating of the swimming water, the dehumidifying of the air, the heating of the space and the heating of water of the pool are solved with the production of heat by means of gas boilers. The close existence of a municipal waste-water collector, which runs alongside the CDM, has allowed the existing heat production installation to be hybridized with a new one based on a thermal exchanger, directly installed in the collector's gallery. The monitoring of the operation and consumption of the system has allowed to verify a percentage reduction of emissions of 37.5% and a percentage reduction of energy costs of 39.2%, in the first stage of operation.
