The Natural Fusion house incorporates a green roof with integrated photovoltaics, a system that uses plants to reduce heat. Also included in the house is a water bladder system embedded in the floor that acts as thermal mass and is emptied for transport to reduce fuel use. The house has a southern overhang, which includes a solar awning coated in PV material, that blocks most of the sun in the summer while allowing sun in during the winter. Learn more about this house.
