Summary:In Swords into Plowshares: At Home in a Missile Silo, Tony Crossley says of his underground home: “The winters are bitterly cold, the summers feature spectacular afternoon thunderstorms and occasional tornadoes, and throughout the year we get days when the wind is very strong. Underground it’s always quiet and peaceful, and no matter how cold it gets outside, the interior never freezes, even though we don’t have any heating yet.” Even in an area with an extreme climate, the ground maintains a relatively constant temperature. Because of this, a house that is built partly or entirely underground can be more energy-efficient than a home above ground. During the winter, the ground is warmer than the air. During the summer, it is cooler. Any large mass of earth tends to maintain a constant temperature. You can see for yourself how this works by testing how long it takes for a thermometer buried in sand or soil to reach the temperature of surrounding air.
