In order to indicate the effect of floor heating on the human body sitting on a floor it should be taken into account to estimate not only heat convection and radiation but also heat conduction between the human body and the floor. The objective of this paper is to introduce modified operative temperature to accomplish the above, and to verify the temperature using experimental data. Experiments were conducted in winter. Subjects were exposed to the following conditions : combinations of air temperature 20℃, 22.5℃ and 25℃, and floor temperature 20℃, 22.5℃, 25℃, 27.5℃, 30℃, 32.5℃, 35℃, 37.5℃ and 40℃ under still air at 50% relative humidity. The modified operative temperature calculated from the experimental data was compared with the modified operative temperature by numerical calculation of heat conduction and radiation interchange. They were fairly agreed with each other.
