 note = {Direct and diffuse solar radiations are necessary when simulating the thermal performance of buildings. In most cases, however, only the total solar radiation on the horizontal surface is observed at the observatories. Therefore the separating procedure from the total radiation into direct and diffuse radiations becomes necessary. In this paper, a new method to separate the global horizontal solar radiation into direct and diffuse components was developed with the Gompertz function. Using the observed solar data of Beijing, Chengdu, Lanzhou, Lhasa, Shanghai, Tsukuba and Ulumuqi, a model for the separation was developed and the results were compared with that from other models., 日本建築学会環境系論文集、第580号},
