In this paper a simple analytical method for design applications, able to provide all the useful criteria for choosing the most suitable ventilated wall, is discussed. As an example two peculiar cases of remarkable importance are investigated: the first in which the inner face is given, and the air duct and the outer face have to be optimized; the second in which, on the contrary, the outer face is given, and the inner face and the air duct have to be optimized. The first case can occur in building recovery interventions, while the second case can occur during the design process. Finally the influence of the variation of some quantities necessary for calculation, such as the heat transfer coefficient of the wall’s outer surface and the relative roughness of the slabs delimiting the air duct, on the energy performance of ventilated walls, is investigated.

Abstract
In this paper a simple analytical method for design applications, able to provide all the useful criteria for choosing the most suitable ventilated wall, is discussed. As an example two peculiar cases of remarkable importance are investigated: the first in which the inner face is given, and the air duct and the outer face have to be optimized; the second in which, on the contrary, the outer face is given, and the inner face and the air duct have to be optimized. The first case can occur in building recovery interventions, while the second case can occur during the design process. Finally the influence of the variation of some quantities necessary for calculation, such as the heat transfer coefficient of the wall’s outer surface and the relative roughness of the slabs delimiting the air duct, on the energy performance of ventilated walls, is investigated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
