Ground source heat pump is a central heating and cooling system that pumps heat to or from the ground. Building Integrated Geothermal system used in this experiment is one of the Ground Source Heat Pump Systems which utilize energy pile. The purpose of this study is to evaluate heating performance of the system. The building is a low-energy experiment apartment in Yonsei University Songdo Campus and the subject is one of the energy reduced houses in this apartment. In the experiment, indoor temperature, outdoor temperature and the inlet and outlet temperature of ground heat exchanger and subject model, were measured. Then the heat pump ' Coefficient of performance(COP) of the heat pump was calculated . As a result, the COP of heat pump is 4-5. Although the depth of the ground heat exchanger in this experment is shallower than usual heat exchanger, the result of heating performance of this system was good as well.
