    In order to verify the results of a numerical analysis of the effects of different dimensional factors on radiant heat coming downward on to an infinitesimal horizontal surface in a gable roofed open-type barn, the authors compared the calcvlatecd radiant heat rate with the measured one in existent barns. The radiant heat rate on the surface of a swine was also measured to evaluate the results of the analysis concerning the radiant heat load of a real swine. Some conclusions follow.
1) Though the calculated values of the radiant beat rate were larger than the measured ones, the calculating procedures seemed to be adequate for practical use in the design of thermal radiant environment in barns (Figs.4, 6, 7 and Table 5).
2) It was suggested that the equations obtained from the results of the analysis could be applied practically to the designed of the radiant environment in barns to easily predict the radiant heat rate (Table 6).
3) From the measurement of the radiant heat rate on the surface of a swine (Fig.8 to 10), the factorial effect based on the radiant heat rate on an infinitesimal horizontal surface tended to estimate the effect based on the radiant heat load of a real swine higher.
