The effect of iwan as traditional shading element on indoor temperature: The case of Diyarbakır houses

In this study, the effect of the use of the iwan as a shading element was investigated. Summer iwans used in Diyarbakır traditional architecture are within the scope of the study. To determine the effect of iwan, use on climatic comfort, the relationship between the rooms, iwans, and courtyards of the houses within the scope of the study was analyzed among themselves and with the outdoor temperature. Indoor temperatures were determined by hourly measurements on three different days during the hot summer period. iwan can be said to give his best performance until 15.00. While the daily temperature change is the lowest in the room and the iwan, the maximum and minimum temperatures are generally the lowest in iwan. It was determined that many design parameters, such as the east wall of the courtyard, iwan opening, and iwan depth, affect the indoor comfort of the iwan together.
