Southeast Asian countries have been experiencing rapid economic growth for decades. As a result, the regional per-capita energy demands are also increasing. Concerns about regional energy sustainability are growing as most of the electricity supplies in the region come from fossil fuels. On the other hand, space cooling is essential to electricity demands. In addition to finding the solution for sustainable energy generation, the conservation of end-user energy utilization is also an important consideration. The use of a Ground Source Heat Pump (GSHP) may be a solution to improve household cooling efficiency in tropical regions. However, study on its application in such climate conditions is limited. This paper discusses the potential application of the GSHP system for space cooling, considering regional climate, ground temperature, and groundwater flow. The numerical simulation evaluates the performance of the GSHP system for a typical detached office building. The ground thermal parameters, building thermal properties, and climate conditions were based on the field data. A year of GSHP cooling was simulated, considering different cases of groundwater flow velocities. The simulation results indicate that the GSHP system can provide a 3.66–3.79 average Coefficient of Performance (COP) over a year of a cooling period in the tropical climate. Furthermore, the results show the effect of groundwater flow in enhancing the COP over a prolonged time.
