From novices to pros, this book explains renewable energy and efficient building practices. Great reference to start design and cost estimation from each section. One of the best features of this book is the addition of the National Electric Code for RE systems. It's possible to pick a building material to build a house, design a solar electric system, decide on appliances, determine the use of a greywater system, and more from 562 pages.
