Product Description

For the past ten years The Passive Solar House has offered proven techniques for building homes that heat and cool themselves, using readily available materials and methods familiar to all building contractors and many do-it-yourself homeowners. True to this innovative, straightforward approach, the new edition of this best-selling guide includes CSOL passive solar design software, making it easier than ever to heat your home with the power of the sun. Since The Passive Solar House was first published, passive solar construction expert James Kachadorian has perfected user-friendly, PC-compatible software to supplement the design process explained in the book by allowing homeowners/designers to enter the specifications of their design and see how changing a variable will affect its energy efficiency. This is the building book for a world of climbing energy costs. Applicable to diverse regions, climates, budgets, and styles of architecture, Kachadorian's techniques translate the essentials of timeless solar design into practical wisdom for today's solar builders. Profiles of successful passive solar design, construction, and retrofit projects from readers of the first edition provide inspiration to first-time homebuilders and renovators alike.

From Library Journal
Published in concert with the Real Goods Trading Company of California, this book explains in detail the whys and wherefores of a particular form of passive solar design, formerly patented but now in the public domain. The patent was held by the author and used while he was president of Green Mountain Homes, a fabricator of post-and-beam kit homes. The science he used and describes here is settled and elegant, even quaint, and is detailed to a degree that could be off-putting to some readers. On the bright side, the enthusiasm he brings to the subject is useful, even to those prospective homebuilders who may not be interested in solar heating and cooling. The book is suffused with a sensitivity to environmental issues of all sorts, a useful perspective in these resource-limited times. An essentially simple book, elegant in presentation and forceful in argument; recommended for extensive scientific (for the references and associated calculations) and/or broader home-building collections.?Alexander Hartmann, INFOPHILE, Williamsport, Pa.

From the Author
I Am The Author

It's been 3 1/2 years since THE PASSIVE SOLAR HOUSE hit the bookstores and I've been pleased with its reception. The book was written as a "gift" to the public as I realized that the design techniques I used were known only to me. The book has accomplished the goal of having readers of all disciplines read and grasp the theory and go on to design their own solar homes or hire a professional to assist them. Sometimes a little assistance is needed from me but I see the book working as intended.

It's been 25 years since I built the prototype of the system. That building served as my model home and office while I was in the business of designing and shipping solar homes in "kit" form. The building still works like a charm for its new owner.

I've lived in my solar home for 21 years. No problems as the laws of physics are hard to defy. It still amazes me how shortsighted our government's energy policies are. For the last 25 years I have purchased the small amount of fuel oil I need for the year in August when fuel oil prices are at their lowest. I've already made 50% on this year's purchase and the heat season hasn't even begun. It's a nice and secure feeling to be able to heat my home entirely with alternate fuels; or if I chose, to use my back-up oil fired system. My solar home gives me the freedom to plan my purchased energy management to use the least amount possible and obtain the lowest price.

If you decide to purchase the book, I hope you'll find it useful in designing and building your new home to utilize our finite resources in the best way possible and best of all: capturing and storing free solar heat.

About the Author
James Kachadorian is a civil engineer with degrees from the Massachusetts Institute of Technology and Worcester Polytechnic Institute. He is the founder of Green Mountain Homes, which gained national recognition as the first provider of over 300 innovative, "kit" solar homes. He has lived in his own passive solar home in Woodstock, Vermont for over 25 years.

Customer Reviews

Thorough exploration of one type of passive solar system
"The Passive Solar House" explains in detail a system that the author patented (patents since expired) for a passive design using a concrete slab for thermal mass. There are detailed worksheets to let a prospective homebuilder figure out expected temperatures and available solar intake throughout the United States. Along with the formulas and worksheets, you can figure out how much insulation, concrete slab mass, air duct area, and heating plant capacity you'll need to incorporate the author's system into your house plans. While the author's patents were in effect his company sold dozens of passive solar houses in factory-built modules. Many of those houses are depicted in both exterior and interior photographs.

While the thermal slab approach works equally well to buffer temperature swings for both heating and cooling, the book's emphasis is on solar heating. Conventional above-ground construction is assumed for the most part, but the treatment on the "sidehill" variant can be extended to included earth-bermed or buried houses.

The illustrations are generally good. In a few cases they are more diagramatic than detailed; however, with enough attention to the illustrations and the text, most details can be gleaned. (I'm still trying to figure out the spacing relationship between the concrete slab channels and the return air duct, though.) But this is definitely a book more about solar design than engineering or construction.

"The Passive Solar House" could be improved by including more techniques for summer shading (such as awnings and overhangs) rather than just assuming deciduous tree plantings (which are expensive to keep watered in desert regions). Coverage of solar absorption properties of floors and windows would also be helpful.

Summary: while not perfect, this is a very good book for explaining the author's thermal slab approach to passive solar design.

Hit the mark - Excellent book and from Vermont!
Excellent ideas. Well presented. Great reference charts. AND he's from my area so it makes his words that much more applicable to my own situation. This book is a must read (even if you live elsewhere! :-)

A Realistic Option for a Solar Home
I was planning a major two-story, south-facing addition to our home on a slab and wanted passive solar already so I was intrigued by this book. It brings together the need for thermal mass to moderate temperature swings, backup heating needs, and provides much needed cooling assistance. I liked how he determined a practical level of insulation and didn't over engineer that aspect. He also covered air quality issues at length.

One small error, I think, was in his design of thermal shutters saying the foil surfaces would reflect heat back into the room while behind wood veneers. I may be wrong, but reflective surfaces don't reflect heat unless there is an airspace adjacent and not up against a solid surface.

I would like to see spreadsheets on disk to make it easier to run your own calculations for your home design and for your region. I would also like to see a chapter on making additions to your home like I'm planning. Adding more information about solar water heating would help complete the book too. I'm curious about the author's experience in this area.
