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 (人们模仿生态系统所建造的可以自给自足的居住环境，也就是其产生的废弃物可以经由厌氧消化转换为甲烷而作为燃料，而剩余残物则可作为种植肥料。剩余食物可用作堆肥或生产甲烷；太阳能经由温室效应收集后可供给家庭、作物热能或水的加热用；风车则可产生电力。因此，在足够的空间、阳光、雨、和风的条件下，理论上，生态房屋可自成一个独立系统，循环其产生的废弃物并使用太阳为其能源。) |
