CASE STUDIES Assessing the Effect of Prefabricated Double-Skin Façade on the Thermal Comfort of Office Building to Achieve Sustainbility Case Studies of Office Complex, Kuchigoro and Office Complex, Garki, Abuja-Nigeria EHSAN REZA AUWAL SAMINU SULEIMAN ABSTRACT The increased interest in energy effcient construction because of environmental issues and rising energy costs has resulted in the adoption of initiatives aimed at rising energy effciency in the building industry as an energy intensive industry with signifcant potential to decrease energy needs and ozone pollution. Prefabricated double-skin façade (DSF) has been proposed as a sustainable building technology that can be used to boost energy effciency and the indoor thermal comfort of buildings in hot climates. The study aims to test double-skin façade as a means to enhance indoor thermal comfort of offce buildings in Abuja Nigeria. Three types of DSFs will be thermally tested using an environmental analysis software which is used to simulate building performance by designers known as Autodesk Ecotect analysis 2011. The analysis will be carried out on two offce buildings in Abuja. In each DSF type single and double glazing of the outer skin will be tested to fnd out which is more suitable. The result showed that DSF has potentials of improving indoor thermal comfort of offce buildings and reduction of energy usage.
