Summary. The Mobile Hermitage is located in Iowa, where summer temperatures can be as high as 35 to 40 degrees Celsius (95 to 104 degrees Fahrenheit).
Cooling System. The cooling system relies upon shade trees surrounding the home to minimize heat produced by direct sunlight during the day.
At night, two 12-volt computer fans are placed in the main downstairs window that faces south (see photo). These fans exhaust hot air causing cool night air to be sucked in through the upstairs north window at the head of the bed.
Because they run on 12-volt power, without the need for any inverter, they are very efficient and can operate for a month or more on a single battery charge.
During the daytime hours, the windows of the home are closed up to keep the cool night air inside the home. This helps the home stay about 10 to 20 degrees cooler than the outside air – made possible by excellent insulation and the shade from trees.
