This study presents a simulation method to predict the effect of the outdoor thermal radiation environment on the performance of a direct gain system. As a result of error analyses for the calculation of incident solar radiation on internal surfaces and room air temperature, the error range derived from mesh resolution is revealed. Also, the numerical experiments show that this method is applicable to the examination of the performance of a direct gain system, taking into account the effects of the position and size of trees and thermal storage mass.
