This study defines a computational algorithm to calculate and evaluate termical performances of a double skin façade (DSF). The definition of the algorithm, expressed in the unit Simulink of Matlab, has been obtained through: the physical-mathematical treatment of the air stream model and the thermal model; the solution of differential equations through the routine writing in Simulink; the simulations to evaluate the constructive parameters of DSF. Simulations have been made in order to evaluate the ideal depth of a single cell of DSF, establishing its dimensions, deflectors height, the position of Venetian curtains in the interstice and appraising the efficiency of pre-heating “η” in winter and the “g” solar factor in summer. Simulations made possible to calculate an ideal depth of 20-30 cm for no-access cavities and to demonstrate that an ideal depth of 60 cm for accessible cavities.

Abstract
This study defines a computational algorithm to calculate and evaluate termical performances of a double skin façade (DSF). The definition of the algorithm, expressed in the unit Simulink of Matlab, has been obtained through: the physical-mathematical treatment of the air stream model and the thermal model; the solution of differential equations through the routine writing in Simulink; the simulations to evaluate the constructive parameters of DSF. Simulations have been made in order to evaluate the ideal depth of a single cell of DSF, establishing its dimensions, deflectors height, the position of Venetian curtains in the interstice and appraising the efficiency of pre-heating “η” in winter and the “g” solar factor in summer. Simulations made possible to calculate an ideal depth of 20-30 cm for no-access cavities and to demonstrate that an ideal depth of 60 cm for accessible cavities.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
