Is day natural ventilation still possible in office buildings with a double-skin façade?

Double-skin facades are assuming an ever-greater importance in modern building practices. But there are still relatively few buildings in which they have actually been realized, and there is still too little experience of their behaviour in operation. To preserve comfort and reduce cooling loads, it is important to apply natural cooling strategies. This article examines the efficiency of the natural day ventilation in relation to the double-skin orientation and the speed and orientation wind.
