This eco friendly Passive Solar House from Green Harmony Home blends a high-performance building envelope with passive solar, zero energy technologies that minimize its ecological impact. Set on a south facing slope, the house takes advantage of natural daylight. A south-facing glazed Green House absorbs sun to heat the house during the cold winters. The clerestory located high in a central wall near the eaves allows additional daylight into a building interior, and may be used for ventilation and solar heat gain. As the sun travels across the sky, its rays hit and reflect through the glass at different angles for an ever-changing spectrum of color and shape. This smart home is 1,500 sq.ft., 1-story, 3-bedroom, 3-bathroom, 1-car garage.
