The purpose of this paper is to explore the effect of interior wall surface temperature (low and non directional radiant heat) on man's thermal comfort. The tests, composed of both 5 college age females and males, were carried out in the late fall of 1976, using the wind tunnel type labolatory in B.R.I.. Each subject was exposed to four different interior wall surface temperatures; 15, 20, 25 and 30c, in a random order, for periods of two hr. The air temperature was changed gradually within the temperature limits of 15 to 30c and air velocity was held to about 0.1m/sec. The rh varied between 30 and 65%. The clothing used was the subjects' own indoor attire. At every 5min, four subjective votes (comfort vote, thermal sensation vote, radiant sensation vote and sensation vote for current of air), were obtained from the subjects. The relations between subjective votes, such as comfort vote and thermal sensation vote, and the ambient temperature or the surface temperature were examined. For college age subjects, the data show that comfort is not described by any single temperature level, but non discomfort zone is determined by the votes of discomfort. And it is revealed that the low and non directional radiant heat affects on man's comfort or thermal sensations, but only a little.
