Describes some original thinking into solar houses: This is the first book on solar house design that I've seen where the author is a professional engineer who worked in the housing industry. He built houses of the conventional design when energy was cheap. When the price of energy started going up he began looking into solar heated homes and eventually got a patent on a passive system that is remarkably inexpensive when compared with other systems.

Basically he designed a large mass of concrete that acts as a big heat sink. That is, when the house is warmer than the concrete, heat flows into the concrete, cooling the house. When the house is cooler. Heat flows out from the concrete, warming the house.

There are a lot of solar systems that work this way, the advantage of his is that it uses standard, i.e. cheap, concrete blocks and a poured slab. He further designs the layout of this concrete so that air would flow through passages in the concrete blocks without the necessity of having blowers to force the air through.

All in all, the book contains some very clever ideas, and has both simple explanations of how it works with enough theory and mathematics to enable you to design your own house. This is made easier through using the software contained on the CD supplied with the book. Here is a fairly complete, fairly simple design tool that will allow you to do a lot of the basic design work of your own solar home. This is not the style of your home, it is the design of the solar aspects.

Anyone thinking of a solar home would be foolish to not spend the few dollars this book costs to get and understand Mr. Kachadorian's concepts.
