Re: How you design an off-grid home to deal with extreme heat

In my house and Earthship, the tire walls keep it cooler. There is less solar gain from the tilted windows. It got up to 92*F here at 8,880′ 39* latitude, but the tire wall areas stayed around 72*F. In Phoenix, Arizona the underground temperature is 70*F and an Earthship there faces north. Unless you have ground water problems, going down into the ground can cool a house.
