Thermal comfort is important to provide building occupants with a comfortable thermal environment for their well-being in buildings. Thermal comfort can be obtained by various occupant actions such as clothing adjustments, opening/closing of windows, and the use of air conditioners, among others. In this study, to explore the factors affecting the comfort/discomfort of people, we analyzed the cognitive temperature, that was given by the subjects being exposed to thermal environmental conditions in a climate chamber, together with the thermal sensation and overall comfort. The experiment was conducted assuming a winter-like indoor air temperature of 22°C with five relative humidity conditions at 30, 40, 50, 60, and 70%. Altogether, 1216 votes were obtained. The mean cognitive temperature±standard deviation was 21.4± 3.2°C. The result showed that people assumed the range of temperature representing their level of overall thermal perception to be quite wide even under the constant indoor thermal condition with the air temperature at 22°C. The cognitive temperature decreased for 30% and 70% relative humidity, and the cognitive temperature.
