Abstract
Engineers use double-skin façades (DSF) to lower the energy consumption of buildings as they can potentially control incoming wind speeds and the amount of solar heat gain. The purpose of this present study was to (1) evaluate the use of DSFs, (2) its efficacy in improving the energy performance of high-rise office buildings in the hot, dry summer climate of the Mediterranean, and (3) to develop an optimum DSF model for this climate based on industry standards and recommendations for high-performance DSF parameters. In order to determine the efficiency of DSFs, two distinct variables, building orientation and the number of DSFs used, were taken into consideration. This study adopted an experimental (generate and test) research design and used Autodesk® Ecotect® Analysis software to develop computer simulations with which to assess 15 single façades, juxtaposed façades, three façades, and four façades on cardinal orientations. The recorded energy consumption and savings were then compared with that of the reference model. The results indicated that the three DSF model, i.e., the S14 model, reduced energy consumption during heating by 28% and by 53.5% when cooling a high-rise office building located in the hot, dry summer climate of the Mediterranean (Csa).
