[EN]The aim of this study is to show an increasing tendency in modern building design. The
work can be divided in three parts. First, contain information about mechanical properties of
perforated metallic materials as strength and stiffness, which are based on the equivalent solid
material concept. This concept is based on the evaluating the effect of the perforations and
analytical results of the behavior of the solid or unperforated materials under bending and
stretching. Next, is present a yield criterion for the perforated sheets with low ligament ratios. In
second part is presented an experimental investigation whose purpose is to analyze the effect of
perforated elements on pressure drops in a double skin cavity. Three different air flow rates and
two different perforated plates are used in order to assess the experimental results. The paper is
ending with the principal material used for manufacturing perforated sheets facades.
