This paper describes fundamental numerical simulation results of the radiative heat transfer among urban structures, non-gray gases, and a human body in an urban street canyon. One-dimensional and three-dimensional numerical simulations were conducted by using Monte Carlo Method and Elsasser's narrow band model in order to verify the characteristic of the effect of non-gray gases (H_2O, CO_2, and CO) on radiative heat flux to the human body. The simulation results show that the effect of non-gray gases increase in proportion to the logarithmic distance between urban structures and human body. These results indicate that the non-gray gases play an important role in the radiative heat transfer to the human body and thermal comfort in the urban street canyon in summer months.
