​Featured on the Discovery Channel’s Renovation Nation, this green solar home built on a narrow infill lot is passively heated, naturally cooled and solar powered. Unlike conventional homes built with wood or masonry, this home is built from the soil from the excavation on site. A machine uses very high pressure to compress the soil into a brick. The compressed earth bricks, wrapped with a continuous layer of foam insulation to retain heat, form a structurally sound massive exterior wall that is an integral part of the home’s passive heating and cooling system. In the winter, the sun coming through the south facing windows heats the house and warms the walls. At night, the massive walls radiate heat back into the home. Features of this house include 3000 gallons of rainwater collection, LED lighting, energy recovery ventilation, and non-toxic materials. The home is certified by EarthCraft Virginia green building program.
