This book describes and illustrates Peter Jon Pearces design for a net-zero energy prototype residence knows as the Pearce Ecohouse. The architecture of this residence embodies new integrated product systems, including structural, space enclosure, floor, and climate management concepts; and it incorporates solar powered heating and cooling systems. This solution comprises a housing paradigm shift, which is intended to further Pearces goal of contributing to the sustainability of the built environment through the implementation of a high-performance design ethic. The Pearce Ecohouse represents a transcendent solution that sets aside sentimental, and nostalgic, approaches to residential building design. The project redefines residential building materials and technology, and conceptualizes an alternative vision of what a house should be.
