Abstract :

Thermal comfort in enclosed intermediary spaces is an important aspect of architectural design that affects the performance of buildings during their operational phase.Until optimal thermal conditions are present in a space, an individual cannot make the best use of that space. Most recent studies on thermal comfort in Iran have focused on traditional residential buildings, with less attention given to public and educational spaces. Intermediary enclosed spaces in buildings, due to their stronger thermal connection to the external environment compared to the main interior spaces, require different thermal standards. In contemporary public buildings, these spaces include circulation areas, lobbies, corridors, and atriums. Their location makes them more thermally exposed to the outside, resulting in greater thermal separation from the building's interior spaces. However, ventilation systems and thermal comfort standards designed for main spaces are often applied to these areas, which can increase energy consumption.Moreover, these spaces differ from the main interior spaces in terms of their usage, the duration of occupant presence, the type of clothing worn by users, and their activities. Users encounter these spaces upon entering the building, and their thermal perception in these areas can impact their overall comfort in the interior spaces. This review article, through deductive reasoning and a literature review of previous research, explains the theoretical foundations of thermal comfort and uses observations to examine environmental conditions and occupant behavior in enclosed intermediary spaces of higher education institutions in Iran’s hot and dry climate. Previous research indicates that conventional standards for designing these spaces are unsuitable and that modifying them could lead to energy savings across the building. Additionally, research shows that using the Adaptive Model (AM) to determine neutral temperature and thermal comfort in these spaces is more effective than the Predicted Mean Vote (PMV) model, offering a more accurate assessment of thermal comfort in these dynamic spaces.
