Abstract: Geothermal probes are increasingly used for building heating and cooling. This leads to a more complicat- ed dimensioning of the boreholes and the building facilities. There are already many tools to simulate ground probe fields in varying degree of detail. In most cases, these programs focusing either on the soil (eg. EWS, FeFlow) or on the buildings and facilities (eg. TRNSYS, EnergyPlus) and they require a broad range of input data. In early design stages there is often a lack of time for detailed simulations. There- fore, a simplified model is developed during a semes- ter project at the University of Applied Science in Rapperswil (HSR) which contains both system com- ponents and ground probe fields. The model should help to determine important data required in the early project planning phase, based on few parameters to proceed with the project until the more detailed simu- lations are evaluated.
