【Abstract】 This paper explored a method that can accurately simulate the solar radiation transmittance of multilayer translucent systems, which considers the difference in spectral properties of different layers of materials and the influence of incident angle change. A spectral model was built with its accuracy verified under laboratory conditions and real working conditions. The experimental results show that the simulation results of the spectral calculation model are in good agreement with the experimental results. Under the laboratory conditions, the average relative error between the spectral model and the experimental results is 1.723%, and the Nash coefficient is 0.686, realizing a 46.284% higher accuracy than that calculated by the spectral model. Under real working conditions, the Nash coefficient of the indoor heat gain calculated by the spectral model and the experimental results is 0.989, with a root mean square error of 11.14 W/m~2, while the simulation results of the traditional model have a large error with the Nash coefficient of 0.763 and the root mean square error of 51.23 W/m~2. The comparative analysis of heat gain between the model and the traditional model in different areas, and directions shows that the traditional model overestimates the energy-saving potential of aerogel glass in Harbin, Kunming, and Beijing, and underestimates the same in Guangzhou and Changsha.更多还原
