Abstract: The AIA (American Institute of Architects) estimates that 48% of all greenhouse emissions emanate from buildings. By increasing a building's energy efficiency, we can reduce the demand for non-renewable (carbon burning) “grid-based” electrical power. Additionally, there is a need to produce buildings for both residential and commercial use that have a low impact on natural resources and on the environment. It is good stewardship to produce a product that uses sustainable materials, does not pollute the environment, reduces energy demand, and is available and affordable to the mass population. The present invention relates to energy efficient buildings, built in a factory environment using sustainable materials and energy efficient technologies, from the ground up. These buildings could be rated by the LEED rating system, or similar rating system, and could carry a LEED Silver rating or better.
