This paper presents a sensitivity analysis followed by an optimization to improve the performance of a ground source heat pump (GSHP) system for an office building located in Norway, for Oslo, Stavanger, and Tromsø climatic conditions. The ground source heating model was firstly validated by available measured data. The sensitivity and optimization simulations were conducted by using IDA ICE software and its integration with the GenOpt tool for optimization. The sensitivity results showed that the borehole depth was the most prominent parameter. Therefore, by increasing and decreasing the borehole length by 20%, for example for Tromsø climatic condition, the energy supplied by the top heating reduced by 22% and increased by 31%, respectively.
