Comparative Study of Architectural Elements to Improve the Wind Environment in Hot and Humid Climates

Abstract

Population growth and building mechanical devices to achieve thermal comfort have increased energy consumption. The hot and humid climates account for high energy consumption in the building sector. Meanwhile, for centuries, vernacular houses in this climate complied with their environment. This paper examined the vernacular architectural elements of two southern cities of Iran with hot and humid climate conditions on the coast of Makran. However, a comprehensive study of these elements and their role in indoor air quality and the creation of thermal comfort has yet to be discovered. This study incorporated climatic information into a computational fluid dynamics simulation to analyze vernacular architectural elements in the study area. By combining the architectural elements of Bushehr and Chabahar vernacular houses, 13 building models were created, with a component of each element to be investigated. Results showed which elements boost the incoming flow and which models become more effective in developing an enhanced model in terms of ventilation. However, a wind exchanger (Dudkesh) works better than a wind catcher and Taremeh in terms of airflow velocity across the buildings. Additionally, models could establish about
