Best Book on PAHS

Passive Annual Heat Storage: Improving the Design of Earth Shelters by John Hait
Great book on Earth Shelters and the incredible efficiencies you can achieve, but also general lessons on thermal management and the application of PAHS in super-insulated homes. Old book from 1983, cant get info like this anymore!

Interesting depiction of all the ways thermal energy is universally transferred, in this case through a window.
