“…In an essay titled "The Eff ect of the Central Courtyard Pattern in Adjusting the Hot and Dry Climate Conditions of Kashan Houses", Jafarian S, et al [8] demonstrate that in addition to the spatial division and organization of the house's spaces, the presence of a central yard with the right proportions has signifi cantly improved and controlled the climatic conditions in traditional houses of hot and dry climates, especially Kashan houses, and has led to the adjustment of the climatic conditions in winter and summer. In an article titled "Optimum design of the central courtyard in residential buildings against the 120-day wind of Zabul based on CFD analysis", Khaksafi di S, et al [9] aims to fi nd the best placement and appropriate geometrical shape of the buildings in the central courtyard type as well as ways to lessen wind speed, at least in a defi ned central courtyard area, and to lessen pollution emission in the central courtyard, which is amplifi ed by the rotation. In a study by Mazaheri M, et al [10] titled "Analysis of the role of the yard in the spatial structure of Iranian houses using the space syntax method", the spatial organization of various examples of Iranian homes is analyzed, and the common characteristics and elements of the homes are explained, which show the most characteristics of the courtyard in the architectural space of these homes.…”

One way to achieve high energy efficiency in buildings and a reliable architectural system is to use the experiences of local architecture. In this connection, the central courtyard is an element that was used in the past to create comfort in the hot and dry climates of Kashan, Iran. A large part of the literature in the past has focused on this space and investigated factors such as height, length, and presence of water in the courtyard, which are directly related to the studied space. This study addresses the dynamic behavior of air in the courtyard under the effects of its geometric form and the airflow passing by its walls and floor to ventilate the space, aiming to increase efficiency. The Energy Plus analyzes this component, and Open Studio software and the research uses the descriptive-analytical method to investigate the findings. It is concluded that air circulation is best met by an airflow loop inside the courtyard in the central courtyard and it was ultimately revealed that the central courtyard priority per the geometric form is the oval with rectangular being the next. The circular, hexagonal and trapezoidal shapes of the yard have been shown to understand better the movement of the wind adjacent to the bottom of the yard (south-to-north) and the flow of the upper layer (north-to-south).
