Geothermal heating and cooling systems are sustainable methods of temperature control utilizing renewable energy. These systems leverage the subsurface temperatures of the Earth by transferring heat between a fluid and its surroundings underground. This transfer of energy provides heating during colder months, and cooling during the hotter times of the year due to the consistency of the temperature below the Earth’s surface year-round. Implementing a Geothermal heating and cooling system can save a significant amount of money annually in the form of decreased heating and cooling costs for both residential and industrial applications. Geothermal systems are versatile in the ways that they can be used, for not only residential buildings, but also large commercial buildings. The Massachusetts General Hospital (MGH), located in Boston, MA, is known as one of the top hospitals in the country and therefore utilize a significant amount of energy for heating and cooling. This provides an excellent opportunity for a Geothermal heat pump to be implemented at the MGH. This paper explains how installing a Geothermal vertical closed loop system at the Gray Building of the MGH can significantly reduce costs on heating and cooling. Currently, 37% of the total yearly energy consumption by the MGH is used for heating and cooling of the facility. By implementing the plan outlined in this paper, the MGH facility would see up to 60% savings in heating and cooling costs annually, resulting in a savings of $1,218,626 per year.
