Performance Evaluation of Ground Heating and Cooling Systems - Long-term performance measurements of two case buildings
Geothermal energy is one of the oldest and most sustainable energy sources and has been used for thousands of years. The temperature of the ground at shallow depth is fairly constant, above the air temperature in winter and lower than the ambient temperature in summer. Shallow geothermal energy systems can thus be used to provide heating and cooling with or without heat pumps. This study aims to
