Abstract

Solar radiation has a significant effect on indoor thermal comfort and building energy consumption. In this study, the accuracy of daylight coefficient（DC） method was verified through experiment. Then, the DC method was used to calculate the increment of mean radiant temperature of a manikin（ΔMRT）, and the result was compared with the original SolarCal（SC） method. Afterwards, the revised SC method was proposed to calculate the solar heat gain of the manikin, and compared with the result by the DC method. The calculated results indicate that the maximum difference of diffuse ΔMRT between the revised SC and DC method is optimized from 4.66 ℃ to 0.92 ℃. Further, in this study, the revised SC method was used to analyze the solar heat gain of the human body in the building throughout the year. This study provides some reference for the evaluation of passive solar buildings and the parametric optimization of building HVAC systems.
