The Sabat is one of the distinctive elements of vernacular architecture in the historic urban fabrics of Iran’s hot and arid regions. By covering part of the passageway, providing shade, and modifying the microclimatic conditions, it plays an important role in moderating the ambient temperature and improving the thermal conditions of circulation routes. Numerous studies have examined the climatic performance of Sabats, yet the relationship between this architectural element and its behavioral and social consequences has received less attention. The present study adopts a descriptive-analytical approach based on library research to reinterpret the role of the Sabat in relation to its physical characteristics, microclimatic conditions, thermal comfort, and social interactions. It seeks to answer the question of how the Sabat can contribute to enhancing social interactions through microclimate moderation and the provision of thermal comfort. Within this framework, the enclosure, shading, degree of spatial containment, and geometry of the Sabat are considered influential factors in reducing solar radiation and moderating the microclimate. The findings indicate that improved thermal conditions provide a more favorable setting for presence, staying, and optional activities in the passageway, while continued presence increases opportunities for encounters and social interaction.
