Abstract: Facade systems, as one of the most complex elements of building, are largely responsible for both the energy-performance and overall aesthetic qualities of a building. With day-to-day innovation in materials & modern technologies, various different materials other than glass are available which can be used for facade of building. Ethylene Tetra Fluoro Ethylene (ETFE) is one of the most exciting materials in today’s design industry and has set the construction world alight with the potential it offers. This research is about study of ETFE; An innovative material & its application as facade material for tall buildings in tropical countries.
