Geothermal ground cooling is a passive cooling strategy that uses the stable temperature of the earth to reduce indoor air temperature.

At a certain depth below the surface, the ground maintains a nearly constant temperature year-round - cooler than the air in summer and warmer in winter. In this system, a fluid circulates through underground pipes, allowing the building to release heat into the cooler earth. As warm indoor air passes over cooled surfaces or through a heat exchanger, its heat is absorbed by the fluid and carried underground, where it is emitted into the surrounding soil.

This continuous heat exchange process reduces indoor temperatures naturally, minimizing or eliminating the need for conventional air conditioning and significantly lowering energy consumption.
