This is a useful text that progresses in a step-by-step manner to help us understand passive solar building principles. The author draws upon his experience as a successful builder of passive solar homes to teach us the dos and don'ts associated with this specialized type of construction. He includes information about his own formerly patented technique, the Solar Slab, which uses the home's foundation to store heat from the sun.

Materials used are all ordinary supplies. Techniques can be adapted to any climate. The numerous illustrations do a great job of supporting the text, helping us visualize exactly how the components of a passive solar home work. Mr. Kachadorian has also included worksheets and formulas to help each of us design a home to our exact specifications. This is an excellent resource for anyone who wishes to learn more about passive solar homes.
