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.

Jeong, Woon Seon 한국의류학회 2001 한국의류학회지 Vol.25 No.9

여성의 생리주기가 행동성 체온조절에 미치는 영향을 관찰하고자, 본 연구에서는 6명의 건강한 여자대학생을 대상으로 하여 22.5℃와 55%RH의 환경에서 피험자 스스로가 의복을 선택하는 쾌적의복선택 실험과 피험자 스스로가 온도를 선택하는 쾌적온도선택 실험을 각각 수행하였다. 평균피부온은 생리주기에 관계없이 쾌적온도선택 실험보다 쾌적의복선택 실험에서 높게 유지되었고, 생리주기에 따른 쾌적착의량과 쾌적온도의 차이는 보이지 않았다. 그러나, 6명의 피험자 중 4명의 피험자가 선택하여 착용한 착의량은 황체기보다 여포기에 더 많았고 (p<0.05), 5명의 피험자가 선택한 쾌적온도 역시 황체기보다 여포기에 평균 1.4℃ 더 높은 것으로 나타났다(p<0.01). 이러한 결과는, 피부의 온도를 조절함으로써 여포기보다 황체기에 심부체온을 높게 유지하기 위한 행동성 체온조절반응을 나타낸 것으로 보이나, 보다 명확한 결론을 내리기 위해서는 다양한 환경조건에서 다수의 피험자를 대상으로 하는 후속연구가 지속적으로 수행되어야 할 것이다.

Most energy using in building part is mainly consumed for heating and cooling to meet occupancy's comfort temperature. Generally, heating energy consumption show high value than cooling energy in Korea because of high temperature difference in winter season as compared with summer in apartment building. The efforts to develope mechanical performance have been studied to reduce energy consumption in building energy field until now. However, the energy consumption in building is impacted by not only system performance but also PMV particularly at temperature and Clo value. This means that energy consumption can be changed by occupancy's comfort setting temperature in apartment building. This study investigated the passibility of overheating in apartment building by occupant's low Clo and its setting temperature from preceding research and then the heating energy consumption by setting temperature was calculated with ESP-r. The effects of heating energy and CO₂ reduction are also evaluated quantitatively with Clo value. The results showed that keeping ISO-7730 standards can reduce heating energy up to 21% in compared with option 2; also, wearing underclothes with ISO-7730 standard can considerably reduce heating energy consumption up to 50%. As compared with option 2, the reduction of CO₂ emission for option 3 showed 0.63TCO2 of kerosene, 0.49TCO2 of LNG and 1.09TCO2 of electricity. The option 4 can be reduced by 1.48TCO2 of kerosene, 1.16TCO2 of LNG and 2.57TCO2 of electricity respectively.

The studies for mechanical performance development have been examined to reduce energy consumption in building construction field. However, The energy consumption using in building for heating is impacted by not only system performance but also PMV particularly at temperature and clo. Most energy using in building part is mainly consumed for heating and cooling to keep comfort temperature. Heating energy consumption is bigger than cooling energy in Korea because of temperature difference in winter in comparison with summer at apartment building. This means that energy consumption can be changed by occupancy's comfort setting temperature in apartment building. This study evaluate actual comfort temperature range by clo and examined heating energy consumption by Esp-r and CO₂ reduction possibility. The results show that keeping ASHRAE standards can reduce heating energy up to 23%; also, wearing underclothes with ASHRAE standard can reduce heating energy up to 47.8%. Option 4 showing Maximum CO₂ emission reduction indicates that kerosene. LNG and electricity can reduce 1.5t, 1.7t, 2.46t respectively in comparison with option 2.

The purpose of this study is to confirm the necessity and significance of applying a dynamic clothing insulation for controlling the thermal environment. For this purpose, the comparative analysis of indoor thermal comfort in the residential building was conducted with three different control methods: 1) DBT (dry-bulb temperature)-based control, 2) PMV (predicted mean vote)-based controls reflecting the fixed clothing insulation, 3) PMV-based control reflecting the dynamic clothing insulation. DesignBuilder was employed for a residential building modeling and the thermal comfort analysis which was accessed with PMV and PPD (predicted percentage dissatisfied) indicators. As a result, the PMV-based control applying the dynamic clothing insulation satisfied the comfort ranges of the PMV and PPD at all times regardless of the season. On the other hand, in the case of the DBT-based control, the average PMV value was out of the comfort range in both seasons, and the PPD value was more than twice that of the PMV-based control reflecting the dynamic clothing insulation. In addition, PMV-based control reflecting fixed clothing insulation resulted in a slightly cold condition in the morning and at night in both seasons as presenting PMV values below –0.5 and PPD values over 10%. In conclusion, from this study, the possibility was confirmed that the PMV-based control reflecting dynamic clothing insulation can provide a comfortable thermal environment for the occupants. Therefore, it is necessary to apply the accurate value of the clothing insulation in order to comfortably control the thermal environment, and a follow-up research should be conducted to develop a prediction model of the real-time clothing insulation.

In this study, comfort temperature is studied and how clothing influence occupants' thermal comfort is also investigated through literary review of present researches. A change of clothing insulation value according to the passage of time is especially studied by collecting and analyzing data and result from other references. Total 53 reference between 1983 and 2006 include articles in journals and proceedings as well as master's or doctor's thesises, and mainly conducted experiments in chambers or field study at residential buildings. As a result, residents indoor clothing is steadily decreased. It is regarded as building insulation technology has been greatly developed. Accordingly, indoor temperature and comfort temperature which residents reported have a tendency to be increased. This result intimates excessive heating during winter and would be contributable to future researches about energy consumption and CO₂ emission.

서울·연변간 착의실태 조사분석 : 착의량을 중심으로 Focusing on the clothing weight

이원자,오순 한국의류학회 1999 한국의류학회지 Vol.23 No.7

In order to find out the influences upon not only the thermal resistance of human body but also the clothing action and the clothing weight, which are caused by the differences in the thermal living conditions by using air conditioner and so on, to adapt themselves to the changes of their residential environment according to the changes of seasons, we investigated the clothing practices upon the male and female students in Seoul and Korean male and female students in Yanbian who are estimated to have different thermal living conditions in spite that they are same folk as well as living in the same age. 1. The total clothing weight of body surface erea was increased in order of summer, autumn, spring and winter seasons and by seasons, the changes of the clothing weight were found in both areas. In Seoul, the changes of upper outwear clothing weight were found on both sexes but in Yanbian, the changes of underwear weight were found on both sexes. And the underwear weight of both sexes in Seoul was lighter than that of both sexes in Yanbian. 2. Those in Seoul tended to fell colder in winter and hotter in summer than those in Yanbian on account that the formers are more sensitive of thermal conditions than the latters. 3. Comparing clo-value calculated by the fomula of 稻垣 with the Winslow's clo-value, those in Yanbian had higher thermal resistance than those in Seoul. Consequently, those in Seoul adapted themselves to the seasons by controling the upper outwear weight but those in Yanbian did it with underwear weight. The male and female students in Seoul, tended to feel colder in winter and hotter in summer than those in Yanbian because the thermal sense of the former is more sensitive than that of the latter.
