Experiences with commercial ground-source heat pumps

Although it has been proven that ground-source heat pump (GSHP) systems are effective in reducing building energy consumption, mechanical designers need to consider several factors before recommending their use. In this regard, the American Society of Heating, Refrigerating and Air Conditioning Engineers published several case studies of the design and performance of a wide variety of commercial and institutional building GSHP systems in North America to increase member awareness and understanding of the systems and confidence in this energy efficient heating and cooling technology. Case studies include information on the rationale for installing GSHP and descriptions of the building heating, ventilation and air conditioning (HVAC).
