This multidisciplinary study on the effectiveness of Badgirs uses in-situ measurements, wind tunnel tests, and CFD-based numerical simulations to understand their functioning. The results have shown that Badgirs can be effective in regulating temperature in buildings, particularly in hot and dry climate zones, and numerical simulations have identified the optimal angle for effective use. This research will enable the design of more energy-efficient buildings and improve natural ventilation systems in hot and dry areas.
