How Earth Berming Works: The performance of this structure relies on thermal mass and geothermal regulation. The surrounding soil acts as a thermal battery, absorbing and slowly releasing heat (thermal lag) to dampen the effects of extreme outdoor temperatures. At several feet below the surface, the earth's temperature remains relatively constant year-round (typically between 55 and 60 degrees Fahrenheit). By burying the walls beneath this thermal boundary, the house interfaces with a stable temperature zone. This reduces the temperature differential between the inside and outside, making the structure warmer in the winter and cooler in the summer than a conventional home, thereby requiring less energy to maintain a comfortable indoor climate.
