The 12th edition of the International Conference on Solar Energy for Buildings and Industry, EUROSUN 2018, was hosted by HSR, the University of Applied Science Rapperswil. It was a forum for scientists, engineers, architects, and representatives from industry and business to present and discuss their latest findings, developments and perspectives.
Two presentations were given by Task 56 Experts at the EUROSUN 2018 conference.

Potential of covering electricity needs of a flat of a MFH with decentral compact heat pumps with PV – Simulation study for different DHW profiles and PV field sizes
Presented by: Toni Calabrese, Innsbruck University, Austria
Abstract - Heat pumps in combination with PV are discussed as one of the key technologies in a future sustainable energy system. A simulation study of a flat in a multi-familiy-house (MFH) with decentral compact heat pumps and with a photovoltaic (PV) field was performed in the CARNOT/Simulink simulation environment in order to evaluate the potential to reduce the purchased grid electricity. PV electricity is self-consumed covering electric power requests for heating, ventilation, appliances and Domestic Hot Water (DHW) preparation. Three different electric power profiles for DHW preparation and two PV fields (roof, roof and façade) were analysed.The results of the simulations show that just a small percentage (below 26%) of electricity demand can be covered from PV field energy. The installation of a PV field also on the façade of the flat does not reduce significantly the purchased electricity (-11% in best of cases), while the use of daily electric storage could be evaluated to decrease further the purchased electricity (maximum reduction of -27%). The use of annual primary energy factor instead of monthly values overestimates the reduction of primary energy demand in all cases compared to the case without photovoltaic system.
