Abstract Ground source coupled heat pump systems are increasingly popular for heating and cooling buildings due to their energy efficiency and environmental benefits. However, current standardized calculation methods for determining the actual heat demand mostly consider long-term average boundary conditions, limiting the accuracy of system efficiency predictions. This study presents an innovative approach for coupled modelling of ground source heat pump systems, using the open-source software OpenGeoSys for underground heat transport processes and Modelica for surface facility simulations. By coupling the subsurface simulation with thermal facility simulation results and mutually influencing each other, runtime-updated results and integrative system considerations can be achieved. The proposed co-simulation method allows for more accurate predictions of ground source heat pump system performance and enables comprehensive system design considering both subsurface and building systems. The potential implications of the study include improved system design and operation, which can support increased energy efficiency and reduced environmental impact.
