ENERGY PILE AND HEAT PUMP MODELING IN WHOLE BUILDING SIMULATION MODEL

Jevgeni Fadejev, Jarek Kurnitski

Abstract: With growing demand in improving building's energy efficiency, utilization of energy from renewable sources becomes more common. Due to lack of design guidelines, some simplified approaches are applied to solve complex building's geothermal heat/cold supply plants. This paper focuses on modelling of the detailed plant with heat pump and energy piles in IDA ICE. The results of commercial hall-type building case studies showed, that energy piles could be effective, as long as the thermal storage is considered. The comparison of results showed, that detailed simulation results might significantly differ from simplified borehole design software. Simplifications in detailed model computational grid can reduce computational time but affect the results accuracy.
