A hybrid façade system was investigated, which consists of single pane (outer skin) and a Triple Glazed Unit (inner skin). The shading element is placed within the cavity between the inner and outer skin. If the system is properly designed, natural ventilation can extract the heat from the cavity, reduce the air temperatures and hence the heat transmission to indoors.

Through a parametric study we analyzed the effect of the natural ventilation and different solar control coatings on the performance of the system. Additionally we provided recommendations regarding glazing build-ups and the need for proper ventilation in different facade areas.
