For beginners, this book explains what a passive solar house is (it is NOT the same as photovoltaic (PV) panels that produce electricity for your home), and how to design a home so that you can achieve up to 90% energy efficiency, reduce utility bills, and thereby save money from the time you move in, month after month, year after year, for the lifetime of the home. A passive solar home is SIMPLE: let the sunshine in through south-facing windows (solar south), keep the sun out in summer (properly designed house overhang), store solar gain in thermal mass (in the home's interior), and prevent heat loss (superinsulate the envelope). There are formulas and easy principles and concepts, rules and guidelines to learn how to design your home, which are provided in this easy-to-read book.NOTE: This book was taken out (and included in) my other book "Cheapskates Passive Solar Home: Design for DIY Straw Bale or Green Building: Thrifty Ways to Barter and Find Cheap Used & Free Materials on a Frugal Budget" in its entirety, just in case you'd rather have the larger version that covers all of this passive solar info PLUS much, much more. I made this "Simple Passive Solar House" book for those who just wanted the basics and did not need info on straw bale or 'cheapskates' tricks and tips. At least you know you have a choice.: )
