Energy performance of building components through a finite-element model

In this paper the authors present the results of some experiences made by using a simulation and analysis model (FEM) which has been suitably studied to assess the behaviour of ventilated and breathing external wall panels. Four types of panels have been realized and submitted toreal workung conditions for about one year during which the parameters whiich have been afterwards used to validate the mathematical model, were recorded. One set of analyses allowed the identification of the most meaningful typology of panel on wich the model was then developed.
