buildings. This paper presents results of wind tunnel tests conducted to evaluate the influence
of ventilation modules positioning on a fa{\c c}ade system. Modules positioning was modified,
resulting in different fa{\c c}ade configurations. The tests were carried out with the use of a model,
varying the position of the ventilation modules in the fa{\c c}ade configuration. The cases tested
were six ventilation modules positioned below the window-sill (ventilated window-sill), and
three ventilation modules positioned above and below the fa{\c c}ade. The fa{\c c}ade system proposed
was movable and interchangeable so that the same basic model could be used to test the
possibilities for ventilation. 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. Single-sided and Cross ventilation were considered for wind speed measurements.
Results show the use of six ventilation modules positioned below the window-sill, forming a
{\textquotedblleft}ventilated window-sill{\textquotedblright} is the best solution in terms of natural ventilation.
