In this paper, the simplified model of occupant for evaluating a radiant cooled space was proposed. The model was constructed by combining some kinds of cylindrical and rectangular parts to simulate a shape of the real subject accurately. The geometrical validity of the model was examined. As a result, an effective body surface area which contributes to a radiation and convection heat transfer and an effective radiation area of the real subject agreed well with those of the model. Furthermore, a skin temperature at some typical positions on the body surface and a partial thermal resistance of clothing were defined respectively on the basis of measured values and they were added to the model as thermal properties. Finally, the model was applied to an analysis of thermal environment in the radiant cooled space and a local thermal environment around the model was evaluated quantitatively. The analyzed value of a mean surface temperature on the body agreed well with that on the real subject. The practical validity of the model was verified.
