Investigation of thermal behavior of traditional geometric patterns (khavoon chini) in the external hollow walls of Dezful double-walled walls in order to revive cultural identity

Traditional geometric patterns in architecture and decoration are rooted in the cultural identity of each region and in cities such as Dezful, they display its special cultural and identity characteristics. In Dezful, the geometric patterns of the bricks, known as the khavoon chini are one of the hallmarks of the citychr('39')s cultural identity. Due to the hot climate of Dezful, the architects used hollow walls with the mentioned patterns to shade with climatic purposes. The traditional styles created in each region are the result of the experience of people who tried to create the best performance for the buildings of the region by using local elements and materials. As in Dezful, by using bricks and geometric patterns, in addition to creating special decorative elements of the region (khavoon chini), they have been thinking of creating shade in the high temperature of the city. The important point is that the thermal behavior of these patterns has not been compared and how in contemporary architecture these patterns can improve the thermal performance of walls is unknown. This study tries to revive the cultural identity of the region by using traditional geometric patterns such as khavoon chini, to provide a solution to improve the thermal behavior of hollow shaded walls and by examining the thermal behavior of these designs, to suggest an optimal model that revives the cultural identity of the city. , Have a good performance in terms of climate. The research method of this research is a combined method that in addition to historical interpretive studies, includes experimental and simulation methods. First, with the help of library and field studies, geometric patterns and native patterns were studied and classified, and then the thermal behavior of these patterns on the outer wall of the double-walled wall was analyzed by simulation. In this research, simulations were performed with Energy Plus software. The results showed that the use of traditional patterns in order to revive cultural identity in the form of geometric facades, has a very good climatic performance and reduce the indoor temperature by several degrees in the warmer months of the year. The type of geometric pattern used in the outer wall, the climatic function of the walls is different and each role requires a specific function. Accordingly, cross patterns have performed better.
