Approximately 40% of total CO₂ emissions originate in the building sector, including public properties and buildings. Therefore, primary energy demand in these buildings must be reduced to a minimum, and the share of renewable energy used in energy consumption in public buildings and infrastructure must be substantially increased.
At the same time, public heating networks play a central role in Thuringia's heat supply, a role that is expected to increase in the future. Heating networks contribute to a resource-efficient and climate-friendly heat supply. The heat to be distributed should be produced with low CO₂ emissions or contain an appropriate proportion of renewable energies or waste heat.
Existing district heating networks must be prepared and adapted for this purpose. At the same time, new and existing district heating networks should be newly constructed, converted, expanded, and densified using intelligent storage devices and sector coupling.
