As illustrated by this photo, living in a net zero home does not have to be extremely different than a traditional home. Tenants can easily live a normal lifestyle with tv and other modern amenities. Built in the dessert, the outside temperature can range from 100 degrees during the day to 50 degrees at night and the building manages to keep a constant indoor temperature of about 70 degrees without the use of a heater or air conditioner. The heating and cooling of his buildings comes from the earth itself. He often builds homes into a hill to provide a barrier from the harsh sun. As the first few feet of the soil absorbs heat, the next levels remain at fairly regulated temperature. This design allows for an inhospitable environment to become an ecofriendly safe haven.
