David Bainbridge, founder of the Passive Solar Institute, recently sent us his book Passive Solar Architecture. The book is a great introduction for anyone interested in passive solar architecture. The content is kept simple and straightforward. It allows any novice to become familiar with the main concepts and techniques used in the field. The authors, Bainbridge and Ken Haggard, have also provided a free-downloadable lab manual that students can use to learn concepts and techniques through a hands-on approach.
