Solar Thermal District Heating System Gutleutmatten
• Further development of the district heating supply is an
important pillar of Freiburg’s climate protection concept
• Combining the energy management instruments "heating
network and CHP" and "using solar thermal energy" as an
innovative approach
• Future district heating systems must be able to react to the
fluctuating supply of renewable energies (e.g. provide
electricity reliably in times of low availability of renewable
energies based on cogeneration)
• In the procedure of the development plan, in the tendering
process as well as within the purchasing contracts,
Freiburg’s efficiency standard for new buildings was
required and the district heating connection was obligatory
• It was important to have sufficient thermal demand density
within the area and reach climate neutrality with respect to
the heat supply. Heat prices were considered controversial
by some purchasers.
