Abstract This study presents an artificial sky model to improve simulation accuracies with the ability to include light color information and dynamic daylighting simulations in existing daylight simulation facilities. The image-based lighting simulation method uses sky luminance distribution data to determine the lighting levels. Theoretical analyses and measurements were used to develop a model for the size of the solar disk and its luminance for even the most complex cloudy sky conditions. The model accurately predicts the direct sunlight insolation. Analyses verify the effectiveness of the daylight simulation facility, the design of the luminous part of the hemisphere dome and the control scheme. This facility provides accurate simulations including daylight color information and variable daylight conditions.
