Activities - Site Demonstrations

PATH's Demonstration Sites promote the use of new technologies that will increase the quality, durability, energy efficiency, environmental performance, and affordability of America's housing. These technologies are promoted because they are not generally accepted or understood. PATH works with innovative builders to integrate selected technologies into a demonstration home's design; measure the cost of incorporating the technologies; evaluate how well technologies are accepted by builders, construction trade groups, and homeowners; and assess the technologies' performance.

Most of the technologies on Demonstration Sites have already gone through Field Evaluations, or information on their performance is available from other sources. PATH supports the technologies and their manufacturers, as well as the housing projects and their contractors, through large-scale press events, media coverage, and technical documentation.
