Minimization of the Residual Energy Demand of Multi-storey Passive Houses – Energetic and Economic Analysis of Solar Thermal and PV in Combination with a Heat Pump

AbstractThe optimum share of PV and Solar thermal in combination with air sourced heat pumps or ground water heat pumps is determined for multi-family passive houses depending on the demand for heating and domestic hot water. Starting with an actual project, Innsbruck Vögelebichl the optimum configuration is determined by means of simulation. More general results are derived by virtually changing the number of storeys. Results are investigated with respect to energetic and economical aspects
