Influence of glazing types and ventilation principles in double skin façades on delivered heating and cooling energy during heating season in an office building

Abstract

Double skin fa?ade represents an additional skin on the outside wall of the building with the idea of reducing building?s energy demand. The zone formed by adding a skin can be sealed or ventilated either naturally or mechanically. This paper shows the results of delivered heating and cooling energy for an office building during heating season with 3 different ventilation strategies and 90 double skin fa?ade configurations. The results were obtained by using EnergyPlus simulation program. In all observed cases, adding double skin fa?ade leads to a decrease in delivered heating energy by as much as 55.80%, but delivered cooling energy might increase if proper glazing type is not selected. The best results were obtained by using triple glazing as inner skin of double fa?ade.
