I have been providing energy efficient homes as a home designer and a patent owner of the All Wall System. The AllWallSystem.com is a methods and use patent that makes it so Entry Level employees and Volunteers can build the most energy efficient wall, as proven by Oak Ridge National Laboratory for the U.S. Department of Energy in 2001 when they tested 16 methods of wall construction.
I am a professional engineer licensed in a few US States, but can be licensed in any US State in a matter of a few weeks.
