Abstract	This 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.
