For the analysis based on the thermal model of human body with a large number of nodes, it is necessary to develop the model of simultaneous heat, air and moisture transfer in and around the clothing. For this purpose, the shape of the air layer between clothing and skin should be quantified and modeled reasonably. From this viewpoint, the relationship between heat conductance (determined from the heat flux at the skin surface and temperature difference between skin and clothing) and the thickness of the air layer between clothing and skin is studied with using human subject wearing T shirt. As the results, it is suggested that the empirical equation for determining heat conductance from the thickness of the air layer could be applied to this problem. At the same time, the methodology of measuring the shape of the air layer with using 3D laser scanner is proposed and an example of test case with using mannequin with T shirt is shown. It is shown that this methodology would be valid for the quantification of the air layer between clothing and skin.
