One of the ways to achieve high energy efficiency in buildings and an effective system is to utilize local architectural experiences. 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 article concerns the hydrodynamic behavior of the wind under the effects of the length-to-height ratio to reduce the temperature of settlements in Kashan's hot and dry climate, aiming to yield the highest efficiency from this element. This study uses Fluent, Energy Plus, and Open Studio software using a descriptive-analytical method to analyze the data. In the end, it is determined that since the prevalent wind in Kashan comes from a northeast front, it can be utilized by placing the longitudinal direction of the central courtyard on its path. In addition, the optimal state in all models suggests the central courtyard has experienced a length-to-height ratio of 1to4, followed by a ratio of 1to5.
