Earthships are buildings that utilize passive heating and cooling to regulate indoor temperature, usually constructed from local resources.  For example, windows on sun-facing walls admit lighting and heating, and the buildings are often horseshoe-shaped to maximize natural light and solar-gain during winter months. The thick and dense earth-rammed tire walls, through varying amounts of sunlight and shade, provide thermal mass that naturally regulates the interior temperature during both cold and hot outside temperatures.  There are several eartships in Philly, and this one in Bristol is close to completion.
