Solar greenhouses

Sunroom end-wall diagramThe purpose of Low-Cost Sunroom is to show how anyone who is of average handiness with simple tools can construct a durable, well-insulated eight-by-eight-foot solar greenhouse.  First, there are a few simple facts concerning the sun and heat retention (insulation) that the greenhouse builder must keep in mind.  For a more complete coverage of the following subjects, The Passive Solar Energy Book, by Edward Mazria, is recommended as a basic primer.

The word “solar” in solar greenhouse means that the greenhouse is designed to do three things an ordinary greenhouse cannot do.  The purpose of most older greenhouses was to let in adequate light to grow plants in winter and spring and to protect the plants from direct contact with the elements.  The old greenhouse had to have a heat source to keep soil and air temperatures warm enough to grow plants.  The solar greenhouse (1) uses the sun as its main heat source, (2) is well-enough insulated that it does not lose too much heat overnight, and (3) has a system of storing and releasing heat obtained from the sun.

To see the complete plans for this greenhouse, download the diagrams in this pdf file.  Then learn to build it with the 99 cent ebook Low-Cost Sunroom.
