green building

The self-contained dwelling where man simulates the ways of ecosystems, i.e. his wastes are converted to fuel by anaerobic digestion for methane production and the residues from the digestion are used for growing food. The food residues are composted and/or used for methane production. Solar energy is trapped by the greenhouse effect and used for house, crop and water heating. A windmill would be used for electricity. Thus, given sufficient space, sunshine, rainfall and wind, the ecohouse is in theory a self-contained system recycling its own wastes and using the sun as its energy input. (Source: PORT)
