Since the publication of the book, Passive Annual Heat Storage, Improving the Design of Earth Shelters in 1985, a number of PAHS homes have been built around the world. Here are some of the pictures that have been sent to us.
Still, the most advanced book available on the subject is Passive Annual Heat Storage, Improving the Design of Earth Shelters. This 1983 text is still quite up to date as it teaches the basic methods of understanding natural heat flow methods that never change. Other supplementary materials, home plans and instruction videos are available.
You can order books, videos, and papers on a large variety of topics which are available from the Rocky Mountain Research Center.
