What process uses the stable coolness of the earth to cool a building?

The process that utilizes the stable coolness of the earth to cool a building is ground coupling. This method involves using the relatively constant temperature of the ground to facilitate cooling. Ground coupling typically entails the installation of pipes or ducts buried underground where the temperature remains cooler than the surface air during warm weather. The system circulates air or fluid through these underground conduits, allowing the earth's cooler temperature to absorb heat from the air being drawn into the building, effectively cooling it.

Geothermal heating refers to utilizing the earth's stable temperature for heating purposes rather than cooling, making it a different process. Thermal mass involves materials that can store and release heat energy, primarily used for temperature regulation in buildings but does not specifically rely on the earth's coolness. Passive solar design focuses on capturing and using sunlight for energy efficiency, rather than utilizing the earth’s temperature directly. Therefore, the essence of ground coupling lies in its application of the earth's consistent temperature to enhance a building's cooling efficiency effectively.
