AbstractThis paper presents analytical models developed to predict the overall optical characteristics of domed skylights under direct and diffuse light subject to different sky conditions. The specific objectives were to: 1) predict the overall optical characteristics (transmittance, absorptance and reflectance) of domed skylights under direct beam and diffuse light; and 2) compare the overall optical characteristics under standard sky (luminance-based) conditions with those under real (illuminance-based) sky conditions. The models are based on a ray-tracing technique, and can handle domed skylights of different shapes with transparent or translucent glazing.
