A Zero Energy Home (ZEH) - a home that produces as much energy as it consumes - is an idea whose time has come! Authors David Johnston and Scott Gibson (Green from the Ground Up) explore the design and construction of self-sufficient houses from start to finish. They make the case for a ZEH; cite climate and geographic challenges; describe exactly how to go about building an energy-efficient home; and feature ten houses that were built for zero energy living. With unequaled knowledge and a passion for the subject, the authors walk readers through the process of building and living in a truly green home.
