KomDat: Communication and data exchange concept between district heating supplier - building owner - tenant

Data exchange for holistic optimization

District heating offers great potential in terms of the use of renewable energies, energy savings and cost reduction as well as a reduction in CO2 emissions. Studies of several district heating networks have shown that the 5% most inefficient transfer stations - often due to technical defects such as a “short circuit” between the flow and return - lead to extremely high energy consumption. They significantly increase the need for pumping power and therefore consume more electricity. Projects such as the ML4Heat project have made it clear that optimizations on the grid side alone are not enough. Measures are also required on the secondary side, i.e. in the buildings themselves, in order to significantly reduce energy consumption.

Project objective

KomDat aims to develop a digital and data-based information hub that connects network operators, building owners and tenants. The exchange and joint analysis of existing data should create synergies that benefit all parties involved.
Procedure:

• Promote data exchange: Previously isolated information is brought together in order to obtain a more comprehensive picture.
• Strengthen communication: A communication concept supports an open exchange between all stakeholders.
• Build trust: Transparent and fact-based information strengthens trust between suppliers, owners and tenants.

Synergies and added value - exemplified in three districts

The concept is being tested under real conditions in two Berlin districts and in Cologne. They are investigating how data exchange and communication can be optimized on site.

Expected results:

• Cost savings for all parties involved through more efficient use of district heating.
• Climate protection through reduced CO₂ emissions.
• Greater acceptance for the expansion of green district heating in society.

Long-term vision

The successful implementation of KomDat should demonstrate that an open and cooperative approach leads to a more sustainable energy supply. The knowledge gained can serve as a model for other regions.

Conclusion

The KomDat project relies on cooperation and the intelligent use of existing data to make district heating more efficient, cost-effective and environmentally friendly. Together we are shaping a sustainable energy future for everyone
