(1) Evaluation of human thermal model by experiments with subjectsExperiments with 188 subjects were made in winter and summer from 1998 to 2000. Skin temperatures of each subjects were measured and calculated with human thermal model and compared each other. Calculation results of human thermal model shown agreement to experimental results except in hand or foot. But thermal comfort index. SET* calculated with human thermal model did not agree with subjects' votesr(2) Refine of CFD calculation method and coupling with radiation interactionThe calculation method of shape factor between each wall and human surfaces were hemi-cube method used by Imano et al. and were able to reduce calculation time very much. Calculation method of CFD on curve-linear coordinates was coupled to radiation interaction in walls and human body. But calculation results did not agree with experimental results in whole human surface.(3) Future investigations・refine of human thermal model on thermal comfort index・refine of calculation method of radiation interaction between each wall and human surfaces.

(1)1998 ~ 2000年冬、夏季对188名受试者进行了实验研究。采用人体热模型测量并计算每个受试者的皮肤温度，并进行比较。人体热模型的计算结果与实验结果一致，除了手和脚。但热舒适指数。（2）CFD计算方法的改进与辐射相互作用的耦合各壁面与人体表面间形状因子的计算方法采用Imano等人提出的半立方体法，可以大大减少计算时间。将曲线-线性坐标系下的CFD计算方法与墙体和人体的辐射相互作用耦合起来。但在整个人体表面的计算结果与实验结果不一致。(3)未来的研究·关于热舒适指数的人体热模型的改进·每个墙壁和人体表面之间的辐射相互作用的计算方法的改进。
