This "Eco House" is designed for a new era of more socially conscious living in harmony with nature. It repositions the pioneering solar designs of George Fred Keck for a new millennium, combining traditional and advanced low-energy techniques. A compact floor plan and optimum solar orientation and roof overhangs allow desirable passive solar heating in colder months while preventing undesirable heat gain in summer. The home favors sustainable, recyclable materials and eco-friendly construction practices.
