In the project local heating between housing and work in Friedrichshafen, an energy-efficient heat connection between industry and neighbouring buildings (social, public and church buildings, as well as private housing) is established. The construction of two local heating networks is planned in the immediate vicinity of the Leutholdstraße industrial site, as well as the construction of an energy centre east of the industrial site. The local heating network is fed with waste heat from the industrial companies. In the further course of the project, the two districts of local heat will be connected to each other and other industrial companies will be connected. For the future, the local heating network creates the prerequisite for the energetic integration of further waste heat sources of industrial enterprises and thus incentives to use generated waste heat meaningfully.
