Modeling, Simulation, and Performance Analysis of a Liquid-Infill Tunable Window

Solar shading is important in buildings for better indoor thermal/light environment and energy conservation, especially the tropical region. Compared with conventional windows additional fixed devices, adaptive self-shading functions take up less space require management labor. The present investigation focuses on a compact liquid-infill tunable window, which can provide colored according to surrounding environment. numerical model of window was established basis law mass enabled prediction response under different boundary conditions. Then thermal performance this innovative analyzed comparison triple-layered clear glass windows. Influences solar radiation level, incident angle, ambient temperature were taken into consideration. proven be efficient reducing heat gain cooling season strong radiation. With an 60° total through reduced by 1.60–8.33%. In future, may inserted existing building simulation software as energy-efficient module evaluate its economic performance. study inspire architectures engineers design near-zero and/or carbon neutral buildings.
