    Study of Natural Ventilation for a Modular Façade System in Wind Tunnel Tests

    Abstract

    Wind tunnel tests are a reliable tool to determine the effect of natural ventilation on
    buildings. This paper presents results of wind tunnel tests conducted to evaluate the influence
    of ventilation modules positioning on a façade system. Modules positioning was modified,
    resulting in different façade configurations. The tests were carried out with the use of a model,
    varying the position of the ventilation modules in the façade 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 façade. The façade 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 façades 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
    “ventilated window‐sill” is the best solution in terms of natural ventilation.
