The developed countries organized in 1980's and began to explore the sustaining development of houses/architectures. For example, the action of "green building challenge" adopted new tech, materials and crafts in their designs, and reduced the use of resource within the permissive range.In a word, the development of modern house experienced next several stages: sun energy house, green building, zoology house, sustaining house and smart house. The relationship of these could be explained by the word "including". The range of sun energy house is the smallest, but its history is the longest, even can be ascent to the 19th century, the green house of the England noble. But the actually sun energy house was invented in 1930's. With the appearance of energy crisis, green house was though much of. It not only included the use of sun energy, but also included the other forms of energy, (such as wind energy, water energy and terrestrial heat and so on.) in addition, it also included the amelioration of house's protection, the improvement of natural aeration and reduces the use of energy by the establishments. So green house was differ from sun energy house, it was a general technical system. Moreover, zoology house combined the saving of energy with the protection of environment, it deal with not only the saving of energy which can not be used and make use of the clean energy which can be reused, but also involved the saving of resource (such as wood and water), reduce the pollution of castoff and the recycle of the materials and so on, so its sight is the highest and its field is the widest too.Step into 21st century, with the development of society and expand of outdoor communication, information become more and more important to people of the world.

That is to say, Internet ought to exert its faction in a certain spaces. Second, house is a product, which has many factions, and with the development of economic and society, the factions of house become more various. It is not only being regarded as a place for living, people pay more attention to its other factions: not only meet the demand of substance, but also the demand of spirit. |
