The tight building envelope requires a HRV to provide fresh air, and the home supplements passive heating strategies with a biomass boiler. A combination solar-electric and solar hot water array provides the home with ample supplies of renewable energy. The home even incorporates Phase Change Materials (PCM) to effectively store heat in the winter and regulate heat in the summer. The rest of the walls are insulated with cellulose, or shredded newspaper. The home harvests roof water for use indoors as well.
The interior finishes include a recycled glass bath floor and recycled tire matting on the main level as well as a tile ceiling that spans the internal boxes. Even the staircase gets into the act with bricks mounted on a parabola span.
