A daylighting calculation method for a domed stadium is presented. Based on this method, a computer program has been developed to predict illuminance distribution by daylight in a retractable domed stadium. Direct sunlight and skylight are considered as the daylighting sources in this program. Skylight model is based on the C.I.E. (Commission Internationale de l’Eclairage) Overcast and Clear Sky functions. For the purpose of examine the accuracy of the prediction by the computer program, the calculations were compared with the scale model measurements. A retractable domed stadium was designed and the 1:200 scale model was made. Illuminance measurements were carried out by setting the scale model under an artificial sky. The measured values were compared with the predicted values for the same conditions simulated by the computer program. As for this stadium, the predicted values agreed well with the measured values.
