Query: Good overview of passive solar designs

Everyone I talked to stated this as the first book someone should read to come up to speed on passive solar designs. And it is a good overview. But only an overview, providing lots of concept and a few "rules of thumb" only. Taken for what it is, this is a very good introduction to passive solar concepts. You'll have to look elsewhere for more detailed information if you plan to participate in the design phase of a passive solar building, or to learn enough to evaluate another's design. There are a few good references in the book to other materials as well.
