LowEx-Concepts for the Heat Supply of Existing Multi-Family Houses

Project management: Stefan Hess, PhD
Funding period: 01.06.2016 - 28.02.2022
Funding code: 03SBE0001C
Funding body: Federal Ministry for Economic Affairs and Energy (BMWi)
Promoter: Forschungszentrum Jülich GmbH (PTJ)

The thematic project network »LowEx-Bestand« comprehensively analyses, developes and demonstrates solutions for the application of electrically and gas driven heat pumps, heat transfer systems and ventilation systems in energetically renovated multi-family houses. Within this network, research institutes, heating industry, building technology industry and housing corporations closely collaborate in different research and development projects. The Chair of Solar Energy Systems coordinates the cooperation within this thematic network.

The projects main objective is to extensively develop LowEx (low exergy) concepts and systems for existing buildings, increase their profitability, ensure their quality of operation and thus contribute to an accelerated launch and market diffusion.

The thematic project network consists of a tripartite structure. Within technology projects, the listed companies develop new LowEx components and systems for renovated multi-family buildings. Research partner in these projects is the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg. In the demonstration projects, housing corporations together with Fraunhofer ISE demonstrate the components and systems developed within the technology projects by applying them in exemplary renovation projects. The overarching research project “LowEx-Bestand Analysis” represents the scientific und communicative link of all activities. Partners in this project are the Department of Sustainable Systems Engineering (INATECH) at the University of Freiburg, the Karlsruhe Institute of Technology (KIT) and Fraunhofer ISE.
