Natural light should be effectively used for a low - energy - consuming daylighting design. A useful sky luminance distribution model is thus required for estimating and evaluating a daylit environment as a standard sky. We previously developed a standard sky model named the ALL SKY MODEL. It can represent the sky luminace distribution from clear sky to overcast sky continuously. We have now modified the procedure for constructing the model so that the index for estimating the sky luminance distribution can be derived easily. The standard global illuminance was defined based on global illuminances of clear skies. The normalized global illuminance was obtained by dividing the measured global illuminance with the standard global illuminance, and was selected as the index for estimating sky luminance distribution. This paper describes the new construction procedure : the gatheing of raw data, the arrangement of data, and the selection of indices for estimating the sky luminance distribution. It also reviews various standard skies pruoposed by researchers worldwide.
