A Simulation of The Physical Characteristics of Passively Maintained Closed Cavity Facades
Abstract
In recent decades, numerous innovations have been noticed in the field of facade technologies, particularly
concerning sustainable principles.The adoption of double and multi-layer facades has been increasing, accompanied by a
renewed interest in natural ventilation over the past decade. While both single and double-skin facades possess their benefits
and limitations, the tendencies of sustainable building led to the development of a third type of glass façade, a close cavity
façade (CCF). This mechanically operated façade combines the advantages of both existing types.Integrating these benefits
with sustainable values, a novelvariant of CCF has been developed – a passively maintained close cavity façade that requires
no additional servicing. To achieve this, several physical characteristicssuch as temperature, pressure, and humidityhad to be
observed, providing simulations and experimental results, and giving crucialinsight intothe duration and efficiency of the
close cavity façade system, designed to operate passively throughout its expected service life.
