Assessment of the Inner Skin Composition Impact on the Double-skin Façade Energy Performance in the Mediterranean Climate ☆

Abstract The objective of this paper is to assess the impact of the inner layer composition in a double-skin facade system on the energy requirements of conditioned office buildings. Considering a typical office building in Tunis covered with a naturally ventilated box-facade, simulations are conducted for the hot and the cold seasons. The results show that the implications of the internal glazing type, the glazing surface and the thermal mass are different according to the season.
