Basic Principles of Passive Solar Design by Fred Hopman, President of the Taos Solar Association is a manual I got from Weir’s CD3WD set.
True to form, this book starts out talking about experience building in Nepal, and how the Natives of that country build mountain homes using passive solar design.
I do a lot of research into off grid housing, especially in earth sheltering, thermal mass, and passive solar. It is my goal to build a small house with a zero grid footprint. What good is it to build a home with no mortgage if you have to pay $300 or $400 a month on utilities bills.
In passive solar building design, windows, walls, and floors are made to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer.
Building design elements to be considered include window placement and size, and glazing type, thermal insulation, thermal mass, and shading.
Glo Windows has a good basic primer on 10 Principles of Passive Solar Design if you want basic information before digging into this larger book.
I don’t think it is necessary, as the author did a good job explaining the idea.Basic Principles of Passive Solar Design
