I give this book 9 out of 10 acorns. This book's subject was uncharted territory when first published and deserves recognition for its pioneer status. The ideas and techniques presented in the book probably seemed outlandish and impractical at the time, but the world seems to be slowly catching up to what the author was trying to convey. I think this book is an excellent companion to Mike Oehler's "The $50 and Up Underground House Book", and succeeds in providing an alternative for people who think Mike Oehler's homes are just a little too "down to earth".
The information regarding earth tubes for ventilation, and the design and installation of an umbrella are invaluable for anyone contemplating earth-sheltered structures. The science of thermal mass and the process by which soil transfers heat is clearly and comprehensively laid out in easy to understand language.
I have a root cellar that was inspired by this book with earth tubes wrapped around it, and this fall I'm hoping to finally complete the insulated umbrella installation so that we no longer need a refrigerator/cooler during the summer months.

I really like John Hait's PAHS book - I now have the second edition, and hope to incorporate PAHS into a near-future house.
