Suitable standard data on daylight and solar radiation are absolutely prepared and offered for the excellent energy saving interior environmental design. The first step of the modification of the data by real measurements into the useful standard data is to classify the sky, conditions when the data were gained. A proposal of a means is stated in this paper in order to divide the sky conditions into ordered categories. The sky conditions when the data were measured are arranged based upon the comparison with the sky, luminance distribution data obtained by sky scanning and the theoretical results on CIE(Commission Internationale de l'Eclairage) Standard Clear and Overcast Sky and Intermediate Sky by one of the authors. The sky conditions are finally classifred into Clear, Near Clear, Intermediate, Near Overcast and Overcast Sky. This Research work is deeply related to the IDMP(International Daylight Measurement Programme) promoted by CIE. Its result convinces authors of its great contributions to the progress IDMP and development of interior environmental design.
