Abstract: This article examines the operating principles of passive ventilation systems in residential buildings under the influence of wind loads, with a particular focus on wind-driven airflow mechanisms. Emphasis is placed on the necessity of experimental validation to assess the effectiveness of such systems under realistic wind conditions. A verification approach is proposed through laboratory testing of a geometrically similar scale model in a wind tunnel, allowing for the controlled simulation of airflow patterns and pressure differentials. Key architectural elements—such as wind catchers, solar chimneys, and strategically placed openings—are considered for optimizing natural ventilation. The study highlights the integration of Computational Fluid Dynamics (CFD) simulations with wind tunnel experiments to ensure design reliability and performance accuracy. The obtained results can be used to improve and optimize architectural and ventilation solutions in the construction of energy-efficient buildings, contributing to enhanced indoor air quality, thermal comfort, and reduced reliance on mechanical systems. By utilizing natural wind forces, passive ventilation systems significantly contribute to energy conservation, reducing the need for mechanical cooling and ventilation.
