Analysis on the Optical Performances of Window Film in Korea
Recently, high efforts have been exerted all over the world to reduce energy used in buildings and to prevent environmental pollution.However, despite the fact that windows on buildings cause the greatest amount of heat energy loss, the area of windows on buildings is increasing due to the preference of high buildings, increasing demand of comfort, extended balcony based on the maximum use of indoor area, view, lighting, etc.The increase in window area is causing a major social issue, as the cooling load in summer season increased significantly due to the solar heat gain.The Window Film maximally permits the penetration ratio of visible light inflow and blocks UV and infrared rays.In the summer time, it blocks the inflow of solar energy and in the winter time the warm indoor temperature is maintained to enhance heating efficiency.Consequently, this study will examine the current recognition standards of window films within and outside the nation and analyze the insulation performance and the cooling load reduction effects of window films distributed in the nation so as to develop a recognition standard for high-efficiency constructional window films.
