INVESTIGATING DIFFERENT STRATEGIES FOR LIGHT AND VENTILATION PROVISION IN VERNACULAR UNDERGROUND ARCHITECTURE AND THEIR INTEGRATION WITH UNDERGROUND MUSEUMS ARCHITECTURE-A CASE STUDY IN IRAN

Nowadays, with regard to environmental problems, environmental sustainability as well as previous vernacular buildings and methods have been specially paid attention. In old Iranian vernacular architecture and in some regions by merging in the heart of the ground, it was possible to provide comfort for residents and optimal condition followed by reduction of energy demand in direction of temperature increase or decrease. The present paper describes significance of environmental sustainability by vernacular underground architecture in Iran based on an analytical method. It is recommended the content be used in creation of underground museums due to its various advantages. Since light and ventilation are two important factors inside museums, in order to maintain invaluable historical and cultural works and also merging at the heart of the ground provides the light required for a museum due to indirect natural and local light with sustainable environmental condition and optimal sufficient ventilation, identification of different kinds of vernacular. Underground architecture in Iran can present different strategies in designing contemporary underground museums. In addition, invaluable works will be more effectively protected. Finally, different kinds of vernacular underground architectures in Iran will be compared and studied based on two factors of light and ventilation through a comparative-analytic method. In conclusion, an ideal underground space that meets requirements of an underground museum is obtained. Its aim is to bring about higher environmental sustainability within larger scales.
