Abstract
Fire spread through the façades is widely recognized as one of the fastest pathways of fire
spreading in the buildings. Fire may spread through the façade in different ways depending on the type
of façade system and on the elements and materials from which it is constructed. Ventilated façades are
multilayer systems whose main feature is the creation of an air chamber of circulating air between the
original building wall and the external cladding. The “chimney effect” in the air cavity is a mechanism that
improves the façade’s thermal behaviour and avoids the appearance of moisture from rain or condensation.
However, in a event of fire, it may contribute to the quickest spreading of fire, representing a significant
risk to the upper floors of a building. This study deals with some aspects of fire propagation through
the ventilated cavity in ventilated façade systems. Also we review the provisions stipulated by the
Spanish building code (Código Técnico de la Edificación, CTE) [1] to avoid fire spread outside the
building.
The results highlight the importance of the use of proper fire barriers to ensure the compartmentalization
of the ventilated cavity, as well as the use of non-combustible thermal insulation materials, among others. In
addition, based on the results, it might be considered that the measures stipulated by the CTE are insufficient
to limit the risks associated with this kind of façades systems. The study has been performed using field
models of computational fluid-dynamics. In particular, the Fire Dynamics Simulator (FDS) software has
been used to numerically solve the mathematical integration models.
