Abstract: Two multi-family buildings (MFB) with together 26 flats were designed to achieve a net Zero Energy (NZE) balance for heating, domestic hot water (DHW) preparation and auxiliary energies. The roof of one of the MFB is covered by PV, the roof of the other MFB is partly used for PV and partly for solar thermal (ST). A doublestage ground water (GW) heat pump with a hot gas desuperheater (DSH) provides the remaining energy for heating and DHW. The system was designed with a low temperature distribution system (floor heating) and separate decentral fresh water preparation (DHW plate HX) for optimal efficiency. By means of monitoring over a period of three years and by simulation assisted analysis of the main components, the buffer tank, the double -stage HP with DSH and the system, the performance is improved to achieve the goal of NZE.
