Collaborative project: EnOB: OptiPort – Development and evaluation of optimized climate-neutral refurbishment paths for the portfolio management of multi-family housing stocks taking into account restrictions
Project management: Dr. Andreas Velte-Schäfer
Funding period: 01.10.2024 – 30.09.2027
Funding code: 03EN1100D
Funding body: Federal Ministry for Economic Affairs and Climate Action (BMWK)
Promoter: Forschungszentrum Jülich GmbH (PtJ)
Housing companies play a decisive role in achieving the goal of a climate-neutral building stock. Unlike private actors, they always have the entire portfolio in mind when it comes to energy-efficient refurbishment and replacing heating systems but have so far often taken a less structured approach to developing a refurbishment strategy. Some of the existing tools on the market are not very practical and only take the specifics of companies into account to a limited extent.
Collaborative project: InnoWP - Innovative power electronics for high-efficiency compressor drives in the heat pump mass market; Subproject: System simulation and evaluation
Project management: Dr. Andreas Velte-Schäfer
Funding period: 01.04.2024 - 31.03.2027
Funding code: 03EN4080F
Funding body: Federal Ministry for Economic Affairs and Climate Action (BMWK)
Promoter: Forschungszentrum Jülich GmbH (PtJ)
In InnoWP, improved inverters and semiconductors are being researched for the accelerated market rampup of heat pump (HP) systems. The project addresses the entire performance range of HPs in residential buildings from new single-family homes to existing large multi-family buildings.
Joint Project: EnEff:Wärme: SQ-DurlachII - Demonstration of scalable solutions and development of digital methods for planning, implementation and operation of integrated energy concepts with large-scale heat pumps in existing neighborhoods; Sub-Project: Monitoring of the Durlach neighborhood
Project management: Michael Kropp
Funding period: 01.01.2024 - 31.12.2027
Funding code: 03EN3095C
Funding body: Federal Ministry for Economic Affairs and Climate Action (BMWK)
Promoter: Forschungszentrum Jülich GmbH (PtJ)
The project aims to demonstrate scalable solutions for integrated energy concepts with heat pumps in existing neighborhoods and develop digital methods for their planning, implementation, and operation. This is crucial for accelerating the energy transition in the face of a shortage of skilled professionals and the need for robust transformation pathways in a volatile market and regulatory environment.
Climate and water protection innovation fund: HVAC support swarm: students support the HVAC companies in optimizing heating systems in existing buildings
Project management: Beatrice Rodenbücher
Funding period: 01.07.2023 - 30.06.2026
Funding body: badenova AG & Co.KG
In the course of the climate crisis and, more recently, the energy crisis energy optimization in existing buildings is increasingly coming to the public's perception. As a result, the already urgently needed, fundamental refurbishment of the heat supply in the building sector (“Wärmewende”) is gaining great importance and enormous urgency. It is now important to use this momentum towards a sustainable heat supply. At the same time, the shortage of skilled workers on the one hand and the significant increase in demand for new and innovative heating systems on the other hand leads to overloaded HVAC trade in some regions.

LowEx-Concepts for the Heat Supply of Existing Multi-Family Houses (LowEx-Bestand)
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« (www.lowex-bestand.de) 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.
EnEff:Stadt: Smart Quartier Karlsruhe-Durlach - Focus on evaluation
Project management: Dr. Stefan Hess
Funding period:01.09.2018 - 31.11.2022
Funding code: 03ET1590C
Funding body: Federal Ministry for Economic Affairs and Energy (BMWi)
Promoter: Forschungszentrum Jülich GmbH (PTJ)
The aim of the project is to develop, implement and assess a complex energy supply system for a partially independent power supply in a cluster of five multi-family houses in Karlsruhe Durlach. The planned energy concept consists of a natural gas CHP with local heating supply, two heat pumps and PV systems on the roofs of the multi-family houses. It is meant to minimize up to 50 % of the primary energy consumption and the related CO2-emission in a cost-efficient way. Research partners of this project are the Fraunhofer Institute for Solar Energy Systems (ISE) and the Karlsruher Energieservice GmbH (KES).

Funding code: 03EGB0006B
Funding body: Federal Ministry for Economic Affairs and Energy (BMWi)
Promoter: Forschungszentrum Jülich GmbH (PTJ)
The project EnEff2050Begleit accompanies the funding initiative EnEff.Gebäude.2050. The project is carried out in close cooperation with the Fraunhofer Institute for Solar Energy Systems ISE and the University of Wuppertal (BUW).
ZAFH ENsource: Centre for Applied Science, Urban ENergy Systems and Resource Efficiency (2nd funding Phase)
Coordination: Hochschule für Technik Stuttgart (Prof. Dr. habil. Ursula Eicker)
Funding period:01.01.2019 - 31.12.2020
Promoter: Ministry of Science, Research and the Arts (MWK), European Regional Development Fund (ERDF)
The Research College ENsource (www.ensource.de) develops urban simulation, automation and optimisation tools with associated business models and tests them in practical case-studies of the industrial, commercial and municipal sector. To this end, eight research-intensive colleges, two universities, the Fraunhofer Institute for Solar Energy Systems ISE, and the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) cooperate together with municipalities and associated partners from industry.
