【 摘 要 】

For shading design and energy consumption simulation, hourly diffuse radiation data is necessary. In order to estimate the total solar radiation on surfaces with different spatial orientations, the knowledge of all components on the horizontal plane is required. Available measured data is, however, typically less. The 2004-2013 year's measured data of Shanghai were localized revising of three categories models, comparing the measured data and estimation data by the correlation coefficient and error index. The results show that the three types of models have high accuracy at higher solar altitude and the accuracy of multi parameter logistic function is best. For stations with only daily solar radiation data, the third types of models can be used to calculate hourly diffuse solar radiation.
