A calculation method combined with measurements for predicting convective heat transfer coefficient at skin surface of thermal manikin under solar radiation is proposed. Present method is based on a calculation of steady state heat balance on skin surface of thermal manikin by the numerical simulation of solar radiation and thermal radiation combined with measurements of indoor climate and thermal manikin. Convective heat transfer coefficient at skin surface of thermal manikin is predicted in air-cooling conditions including the insulation effect of solar radiation on thermal manikin in an experimental atrium. As results, (1)it is considered convective heat transfer coefficient at each skin surface is affected by the velocity distribution of the thermal manikin. (2)No significant difference is found in convective heat transfer coefficient at each skin surface whether direct solar radiation reaches the thermal manikin or not. (3)Mean air velocity derived by convective heat transfer coefficient of whole body almost corresponds weigted mean measured velocity, and ratio of mean air velocity also corresponds to that of the supply air velocity in each case.
