Nowadays natural ventilation has gained prominence because its correct use can reduce energy consumption for cooling systems and improve thermal comfort among users. In this paper, we report on the modelling initiative, based on the wind tunnel tests that were carried out for the determination of the influence of natural ventilation in buildings. Indeed, the renewal of air in a closed environment without using an air conditioning system with mechanical elements can lead to energy savings and, in addition, provide air quality. The wind tunnel tests were carried out by varying the positioning of six ventilation modules in the fa{\c c}ade system configuration. The modules were positioned below the window-sill (ventilated window-sill) as well as separately above and below the fa{\c c}ade. The wind speed measurements were taken inside and outside the model for the different fa{\c c}ades configurations to evaluate the best performance in relation to natural ventilation. The results supported the positioning of the six ventilation modules below the window-sill, forming a {\textquotedblleft}ventilated window-sill{\textquotedblright} as the most effective natural ventilation solution.
