APIExecutable4/7Query nowOpen workbench Subscribe🇫🇷France

This API provides geolocated data on the urban heating network (RCU) operated across the Rennes Métropole territory in France. Urban heating networks function by producing heat at central boiler plants and distributing it to subscribers through underground pipelines. The dataset maps the routing of these heating networks, allowing identification of covered areas. It is published and maintained by Rennes Métropole, the local metropolitan authority, as part of its open-data offering, and can support urban planning, energy infrastructure analysis, and studies of local heating provision.Les Réseaux de Chaleur Urbains (RCU) fonctionnent sur le principe suivant : des chaufferies produisent de la chaleur qui est ensuite distribuée aux abonnés via des canalisations souterraines. Cette couche localise le tracé des réseaux de chaleur urbains sur le territoire de Rennes Métropole.
