=Introduction=
A greenhouse can actually be built by digging a hole in the ground and covering it with glass. This takes advantage of the heat stored in the earth during the cold season (warmth in winter, cooling in summer). Therefore very suitable for climates with cold winters. At the depth of several meters, there is very little seasonal variation in temperature. The earth around the greenhouse structure has a large amount of thermal mass.
 
The Benson Agriculture and Food Institute at Brigham Young University examined the concept in detail and has [http://www.bensoninstitute.org/Publication/Manuals/Walipini.pdf put together a manual] with specific designs ([http://openfarmtech.org/wiki/File:Walipini.pdf internal copy here]). Their design costs $250-$300 in materials and is designed to provide vegetables year-round for seven people. This is called ''"Walipini"'' (pit greenhouse) in South America. They built it in Bolivia, high up in the Andes. It is an adaptation of the idea of [http://www.earthshelters.com/Ch_1.html passive annual heat storage (PAHS)] to the greenhouse.

Mike Oehler, of [http://undergroundhousing.com/ UndergroundHousing.com], described a similar concept in his 2007 book: ''The Earth-Sheltered Solar Greenhouse Book'' available [http://www.kickasstorrents.com/the-earth-sheltered-solar-greenhouse-book-by-mike-oehler-pdf-t4604164.html here]. This is an adaptation from his earlier work on underground housing for residential purposes.
