Presents simulation studies that examine and compare the thermal performance of some of the more common types of ground heat exchangers, such as single U-tube, double U-tube, concentric tube, and standing column well (with no ground water bleed), using a mathematical description for the thermal resistance of ground heat exchangers. The system simulations are based on a short time step ground heat exchanger model and are conducted under an equivalent set of conditions considering a small office building. A comparative life-cycle cost analysis was also conducted considering a 20-year system operation.
