Abstract: This paper studies the impact of changing layering configurations, cavity widths and shading apertures of a shading system on the inner cavity surface temperatures of a double skin facade (DSF) in a hot arid climate. Computational fluid dynamics (CFD) thermo-fluiddynamics modelling is used by coupling RNG k-epsilon turbulence model with Discrete Ordinate (DO) radiation and solar ray-tracing model. The optimized DSF is tested on a peak summer and winter day, at 9:00am, 12:00pm and 15:00pm. A flat-shading with 3 aperture sizes (30%, 50% & 70%) is tested to reduce internal surface heat gains.
Keywords: CFD, DSF, Simulation, Cavity-integrated solar-shading
