This study describes computational fluid dynamics (CFD) modeling of ventilated façade. Ventilated
façades are normal façade but it has an extra channel between the concrete wall and the (double skin)
façade. Several studies found in the literature are carried out with CFD simulations about the behavior of
the thermodynamic phenomena of the double skin façades systems. These studies conclude that the
presence of the air gap in the ventilated façade affects the temperature in the building skin, causing a
cooling effect, at least in low-rise buildings. One of the most important factors affecting the thermal
effects of ventilated façades is the wind velocity. In this contribution, a CFD analysis applied on two
different velocity assumptions for air movement in the air gap of a ventilated façade is presented. A
comparison is proposed considering natural wind induced velocity with forced fan induced velocity in
the gap. Finally, comparing temperatures in the building skin, the differences between both solutions are
described determining that, related to the considered boundary conditions, there is a maximum height in
which the thermal effect of the induced flow is significantly observed.Mora Pérez, M.; López Patiño, G.; López Jiménez, PA. (2013).
