초록

Occupants’ clothing level is an important factor to thermal comfort, which is also affected by dry-bulb temperature, relative humidity, mean radiant temperature, air velocity and metabolic rate. As occupants’ clothing behavior is dependent on the seasonal variation of outdoor air temperature, the proper set-temperature for heating and cooling needs to be determined with the consideration of the seasonal variation of the clothing level. However, set-temperatures for summer (26℃) and winter (22℃) are specified as fixed values in most regulations on heating and cooling of office buildings. In this study, the correlation between mean monthly outdoor temperature (MMOT) and clothing level was investigated. Based on the correlation, dry-bulb temperatures meeting comfort ranges were suggested depending on the clothing level. The MMOT was defined with the 06:00 AM outdoor air temperature using meteorological data for past 12 years in Busan, while the clothing level was determined by conducting surveys targeting undergraduate students. The results show that MMOT at 6:00 AM is 0.84~23.88℃, the outdoor clothing level is 1.56~0.41 Clo and the indoor clothing level is 1.15~0.38 Clo. The correlation between clothing level and MMOT can be expressed with linear regression: y(Clo)=-0.0499x(MMOT)+1.5523, R²=0.8923 for outdoor clothing, and y(Clo)=-0.0305x(MMOT)+1.1779, R²=0.7976 for indoor clothing. Under comfortable condition (PMV±0.5), acceptable dry-bulb temperature depending on the clothing level is 16.65~27.20℃ for outdoor clothing and 19.45~27.35℃ for indoor clothing. The suggested dry-bulb temperature can be used as set-temperature for heating and cooling
