So, you want to build a passive solar-powered house. Let's just call it a solar house for brevity, shall we? There are big house plan catalogues online that will just let you order some plans, but if you want to understand the ins and outs and have some input on the design, you might want to grab a book.
Here's what Amazon has on the topic:
The Solar House: Passive Heating and Cooling
-- the book has excellent reviews: "Thorough, concise, and up-to-date info for solar designs"
The Solar Electric House: Energy for the Environmentally-Responsive, Energy-Independent Home
-- aside from having a tediously long title, this book also has good reviews at Amazon.
The Complete Idiot's Guide to Solar Power for Your Home
-- The reviews for this one make it sound like it's pretty basic; if you already have some knowledge of solar homes, the other two would probably be better.
Whatever book you decide to get (if you decide to get one), make sure it's a recent publication (or at least recently updated) as the technology is always improving and evolving.
Also, if you don't mind buying an online book, JC Solar Homes has their own product for sale, a 123 page books with emphasis on solar house plans and how solar houses work. I have not seen the book, so cannot attest to how good they are. If anybody orders one, please leave a comment and tell us if it's worth the money. Solar Home Plans
