Heat pumps are a key technology for the heat transition, yet their implementation in existing multifamily buildings is a challenge. These buildings place special demands on the transfer systems for space heating and domestic hot water as well as on environmental heat utilization. In the joint project LowEx in the Building Stock, solutions for heat pump, heat transfer and ventilation systems in retrofitted multifamily homes were analyzed, developed and demonstrated.
In the final project report, the Fraunhofer Institute for Solar Energy Systems ISE, the Institute for Sustainable Systems Engineering INATECH of the University of Freiburg and the Karlsruhe Institute of Technology KIT present the resulting solutions and some exemplary demonstration objects.
