Geothermal heating and cooling systems are a sustainable, affordable, efficient proven technology. Because the ground absorbs nearly half of the solar energy our planet receives, the earth remains at a constant, moderate temperature just below its surface all year round. However, air temperature varies greatly from summer to winter, making traditional air source heating and cooling less efficient. Geothermal heating and cooling systems take advantage of the stable temperature underground using a piping system, commonly referred to as a “loop.” Water circulates in the loop to exchange heat between a building, the geothermal heat pump, and the earth, providing very efficient heating, cooling, and hot water.
This course will provide an introduction to geothermal heating and cooling systems for commercial buildings including the different types, their operation, financial incentives available and case studies that demonstrate these concepts.
