If you are planning to, dreaming about or just seeking knowledge about building a home and have a serious green agenda then these are the only books you will need. I cannot speak highly enough of these books in terms of content, writing style and links to suppliers. They are factual - demolishing much oft-espoused greenwash. Written by experts in their field and as up-to-date as rapidly changing technologies allow. Formulae explained with worked examples that even I could follow. Photos and diagrams clarifying difficult details. I love these books.
These books are also appropriate for light industrial and commercial buildings and include many sections relevant to this area.
A useful addition to the Bible vol 1, but could stand alone as there was a lot of duplication of information. More technical info than I needed, yet also glossed over some subjects where I would have liked more info.
I bought this book from recommendation and am happy to say that I have not been disappointed. An excellend reference for anyone interested in sustainable design, including example calculations. Highly recommended.
