The use of Nature Potentials in the Interaction with Nature

Among many reasons which can be mentioned for historic settlement in the depth of earth or in the caves, this article pays attention to the motivation of exploitation of soil energy. To this point we attend to introduce special troglodyte architectures in Khoozestan, named Shavadan and Ghomesh, two structures in the depth of the earth. In order to describe unique features of Shavadan and Ghomesh, after a brief overview of effi ciency of soil temperature, an organic – non Iranian case on which many quantitative studies have been done will be introduced. Then a new experiment will be shown briefl y, based on the low temperature of the deep parts of the earth, its restricted oscillation and the ways of transferring this temperature to the interior spaces of the habitats. It is worth mentioning that using constant temperature of soil has been experienced in various forms throughout history and specially in recent decades, but in this article only two cases will be mentioned, which are closer to Shavadan. In continuation, the special functions and effects of Shavadan and Ghomesh will be described in residential tissues and their environments by explaining their history and physical structure. At the end, the necessity of renovation of these structures will be emphasized.
