SensOpt – Solar active buildings with 100 percent solar heat fraction

Fully solar heated single and multifamily houses are already technically feasible. The seasonal storage in these systems is associated with corresponding investment cost and demand for storage volume. This project analyses whether cost and used storage volume can be reduced with the combination of solar thermal with a PV driven heat pump system. Therefore, an existing system will be monitored and new innovative concepts are simulated and optimized. The project is carried out in collaboration with Lucerne University of Applied Sciences (HSLU) and Jenni Energietechnik AG.
