In study of sema and its related architectural spaces in chalabioghlu khanghah, the main goal is to understand the mostimportant principles of spaces formation in the complex.To achieve this goal, at the very first place it’s necessary to study Sema tradition itself in the second step, architecture ofthe complex should be taken to consideration, both as a whole and in details. Acquiring all these information, it wouldbe possible perspective of how the space was shaped and know the prominent factors in this relationship. Also theirfunctions and relations would be completely clarified, in order to have a proper answer for how Sema had effected thesymbolic conformation of the complex. The results will classify the compartments and features which form Khanghahcomplexes in accordance with different levels of Islamic art, as well as the way function had modified the process ofbuilding formation.

Recycling process is one of the most important processes in the trend of sustainable development,a logical reaction against the problems that results from industrial age. Building materials can play an important rolein the process of a building formation or destruction, in fact, materials forms the building nature. Thus, the role ofmaterial and the impact of its recycling in sustainable development context cannot be ignored. Also, due to the rate ofdestruction and renewals that exist in cities and considering to the point that almost half of fuel storages are consumedin the buildings, the mass of materials that are sources of potential energy, should not be ignored. So, it is obvious thatfinding a fundamental solution in this area is necessary. In terms of research performance, this study is qualitative andas descriptive-comparative investigation and selection of the concepts is based on library and documentary methods,surveying some characteristics of recycling which in terms of quality and technique effect on architecture has beenattempted in this research. Therefore, the role of recycling materials and the importance of their potential energy in thetrend of sustainable development are investigated in this paper by descriptive-comparative method and appropriate andoptimum solutions provided in order to reduce energy consumption in the field of construction and building materials.
