As compared with other heating systems, radiant ones are generally excellent for giving us more thermal comfort, which is mainly due to uniform room temperature distribution and weak cold draft induced by space air movement. In order to clarify air movement and temperature distribution of radiant heating spaces, some experiments were performed using a real-scale model room having electric floor heating system. In addition to the present experiments, the authors were also carried out the corresponding CFD analysis, whose result was compared with that of the experiments. The comparison makes clear validity of the analysis of estimating space air movement in the room of this kind. Furthermore, the space comfortableness was confirmed by bodily sensation of seven persons who spent for about an hour in the model room. The observers sitting down on the floor were all healthy males of from 21 to 25 years old with metabolic rate of 1 met and clothing insulation of 0.8 clo. The data reported from them were compared with PMV values calculated by using measured data on room temperature, mean radiant temperature, relative humidity and indoor air flow velocity.
