The imbalance of heat rejection to and heat extraction from the ground has dramatic effect on the performance of a GSHP system, thus affects the heating and cooling energy usage of a building. A parametric study based on different heat rejection/extraction (R/E) ratio was conducted for a 20-year life period to analyze the effect of such imbalance on the energy consumption increment. An analytical relationship between R/E ratio and energy usage factor was concluded for current configuration of ground heat exchanger (GHX). A design guideline is recommended based on the spacing heating and cooling load ratio of a building.
