The local architecture of each region is influenced by its climatic conditions, and humans strive to create a suitable space for living. Wind plays an important role in this architecture, especially in hot and humid regions where local architects have developed solutions for using wind and natural ventilation. Factors such as building orientation, spatial organization, and the use of windbreaks are important in this architecture. Windbreaks, as a means of natural ventilation, use gravity and air flow to provide effective internal ventilation. They are usually installed on roofs and their ventilation capacity varies between 1 and 3.8 cubic meters per second. Positive pressure on the windward walls and negative pressure on the leeward walls cause fresh air to enter and hot air to exit. Windbreaks, as an example of a design compatible with hot climates, are effective in terms of natural ventilation in hot seasons. Due to their design, they can use up to 80 percent of the prevailing winds in summer. Finally, as energy resources are limited and renewable energies have become more important, examining old structures such as windbreaks can help optimize them and adapt to modern needs. Analyzing the hydrodynamic behavior of windbreaks with the aim of optimizing natural ventilation is examined in this article. The results of your studies indicate the importance of designing windbreaks, especially in the southern regions of Iran. Windbreaks, by creating lower air pressure in their lower part, absorb free air flow into themselves, which causes wind inside the building. Even in the absence of wind in the open environment, the wind exits the windbreak at a speed of about 3 m/s, which helps reduce the temperature of the surrounding environment. Wind blowing in windbreaks is of particular importance, especially in the city of Laft and the southern regions. Also, calculating a relationship for measuring wind speed under the windbreak using the multivariate regression method seems to be able to be used as an input for the design of future wind turbines. If this relationship has an acceptable error and appropriate accuracy, it can be a useful tool for engineers and researchers in future research.
