The thermal comfort conditions in a direct gain cell of the NBS/DoE passive solar test facility were analyzed in accordance with the criteria specified in the recently revised ASHRAE Comfort Standard 55-1981, using test data collected during the month of October 1981 and the month of January 1982. It was found that the daytime operative temperature (as measured by the black globe temperature sensors) in an area near the large south glazing exceeded the upper boundary of the ASHRAE comfort envelope by a large amount in a clear day during both the thermal transition month of October and the cold winter month of January. The generally accepted method of computing the mean radiant temperature based only on the interior surface temperatures was found to produce large errors. The reflected solar radiation from the interior surfaces and the snow covered ground was believed to play a significant role on the measured black globe temperature and should be included in the computation of the mean radiant temperature for a space with large glazed areas.
