In the Bavarian town of Moosburg, a climate-neutral alternative to natural gas and oil-based heating was created by setting up a solar-supported district heating network which supplies the Sonnensiedlung. Since this year, 34 residential units in the form of six semi-detached and terraced houses as well as twelve condominiums in two apartment buildings are inhabited and supplied by solar thermal energy and the heat of a biomass boiler. The power supply is provided by photovoltaics and battery storage enabling the implementation of a mobility concept with the neighbourhood's own loanable e-vehicle and an e-cargo bike. The planning of the energy concept as well as the components of the solar thermal system and storages come from the local company CitrinSolar GmbH.
At the beginning of the excursion, the 25 participants were guided through the company premises of CitrinSolar GmbH by Dr. Hermann Riess and got to know the solar panel production as well as the central district heating station with the wood chip boiler. After lively discussions and the opportunity to see the components of the district heating network up close, Prof. Tobias Schrag gave a brief introduction to the EffNet and LEnZ projects. Afterwards, Hanns Koller, Managing Director of CS Wohnbau und CitrinSolar GmbH, presented the concept and the implementation of the CS Sonnensiedlung as a sustainable housing project with a local supply by solar thermal energy. Subsequently, Mr. Riess and his colleague Mr. Beckenbauer explained the possibilities of solar thermal energy integrated in rural district heating networks and presented planning, implementation and operation options based on scientific results. In the lively discussion that followed, the visitors exchanged views with the speakers, especially on the technology of the solar-supported district heating network and on the implementation possibilities of other innovative housing concepts.
The Technology Transfer and International Projects section of the InES is dedicated to networking applied research with regional and international players in the field of renewable energies. This also includes public events within the framework of the projects located here. These are intended to promote both the transfer of knowledge and the discussion about the future of renewable energies and the associated technologies.
