The objective of this paper is to evaluate the thermal radiation environment using mean radiant temperature MRTr which takes configuration factors and equivalent black body temperatures the effect of the inter-reflection and blocking effect of the human body. Numerical analysis of inter-reflection radiant exchange were carried out using Net Radiation method. MRTr was calculated from radiation rate, emissivity and configuration factors on each surface. As a result, The difference between the MRT considering the effect of inter-reflection and the ordinary MRT stood within ±3℃ when the emissivity of a floor changed from 0.50 to 1.00 under the following floor heating condition : the floor surface temperature 37.5℃ and the other surface temperature 21℃. The MRT was influenced by emissivities of each surface in the non-uniform thermal radiation environments rather than uniform environment. It is necessary to evaluate the non-uniform thermal radiant environment using the MRT considering the effect of radiation inter-reflection and blocking effect of the human body.
