The Partnership for Advancing Technology in Housing (PATH) is an industry-government initiative that provides builders with reliable assessments of new practices and technologies in construction. Their mission is dedicated to accelerating the development and use of technologies that radically improve the quality, durability, energy efficiency, environmental performance, and affordability of housing.

Their website offers an A-Z index of many of these new technologies that range from green technology to building and material technologies.

Currently, PATH is working to develop protocols that home remodeling contractors can use to incorporate best practices for energy efficiency into their projects.

The protocols assess the specific contractor practices that affect energy efficiency of an existing home and identify improvements that offer the greatest economic returns and other important benefits to the homeowner over time. They provide guidance to remodeling and trade contractors as well as homeowners, and help ensure that dollars invested in different kinds of home improvements result in maximum energy savings. Remodelers will be able to identify and evaluate potential energy improvements, either as stand-alone "home performance" projects that can improve comfort and reduce energy bills ("Level 1"); in conjunction with other work, such as room additions, bathroom or kitchen remodeling ("Level 2"); or as part of a whole-house approach ("Level 3").

Final draft protocols will be piloted in the industry. Results from the pilot will be assessed and incorporated into a final version, to be released by the end of 2008.
