Evaluation of Environmental Components Affecting Natural Ventilation of theTraditional House of Natanz City

Failure to take advantage of environmental factors in the design and the high consumption of non-renewable energy have caused energy wastage and increased costs in the residential sector. Meanwhile, natural ventilation is one of the most effective factors in creating thermal comfort. The city of Natanz is located in the sub-climate of the foothills. Energy requirements depend to a great extent on the climatic conditions of the environment, and it is possible to position the buildings within the comfort zone for a significant portion of the year by considering environmental factors and utilizing natural ventilation.In the following article, the approach to native housing in Natanz City, focusing on natural ventilation to adapt to thermal comfort conditions, is investigated. Ventilation in four houses from the Timurid to Pahlavi periods in Bagshahr Natanz has been analyzed using Computational Fluid Dynamics (CFD) and the Design-Builder software. The results of the investigations show that the native architecture of Natanz City, incorporating static solutions and mindful consideration of the bed's conditions, has successfully placed these buildings within the thermal comfort zone for many days during the hot season by harnessing suitable natural ventilation.
