One of the most comprehensive methods to cover all of these factors is natural ventilation, which is known to be one of the most effective factors in providing thermal comfort. This factor has always been considered especially in hot and dry climates, and architects have come up with different solutions depending on the climatic conditions of the area. This study investigates one of the most commonly used natural ventilation elements of traditional, wind-driven architecture in warm and dry climates. Therefore, the main purpose of this research was to study and study the ideas and perspectives of traditional architecture in the field of natural ventilation and the influence of elements used in traditional buildings for thermal comfort and temperature equilibrium in hot and dry climate in order to be modeled. From traditional architectural elements to the design of modern buildings, we improve thermal comfort in a contemporary building. For this purpose, numerical analysis of deflector performance has been performed by applying fluid dynamics science and based on simulation in Ennis Fluent software. The results show that the use of windscreen can reduce the temperature to about 9 ° C in hot and dry climate.
