IWAES – Integrative consideration of sustainable heat management in urban districts

Well-adjusted heat and cold balance for sustainable urban development processes

Energy-efficient districts are important for the implementation of the government’s climate protection goals. A well-adjusted heat and cold balance in each district is a prerequisite for sustainable urban development.

Objectives and procedure
The overall objective of the project is to acticate the existing infrastructure systems of urban water management usable for the storage, transport and retrieval of heat and cooling energy within a city district. The infrastructural coupling of the cooling and heating requirements of different consumers forms the basis for a well-adjusted heat balance in urban districts. On the basis of measurements and simulations, existing technologies for heat and cold transport will be further developed, and concepts will be established for integrating the approach into urban planning.

Expected results and transfer
The project provides concepts and technologies for the thermal activation of infrastructures in urban water management. Using a model district in Stuttgart, their implementation and integration into the urban development process will be tested.
