맞통풍 평면형 아파트의 여름철 실내온열환경 조절효과

The purpose of this study is to make clear the indoor thermal effect by cross-ventilation plan type in apartment house during summer. The questionnaire survey was carried out during the 26<SUP>th</SUP> of August～the 4<SUP>th</SUP> of September 2004. The respondents were 174 residents living in two subject apartment estates. One subject estate (we call A estate) was consisted apartment houses having cross-ventilation floor plan. The other subject estate (we call B estate) was constructed apartment houses having ordinary floor plan. The field measurements of indoor thermal elements reflecting natural cooling effect by cross-ventilation were carried out at A house in A estate and at B house in B estate. The measurements in two subject houses were taken on simultaneously the 27<SUP>th</SUP> of August. The residents living in A apartment estate planed cross-ventilation type show positive responses on thermal sensation and airflow sensation. The averages indoor temperature and air velocity in the A house were 0.9 ℃ lower and 0.29 ㎧ higher than the B house. Therefore, it was found that indoor thermal environment during summer in the house having cross-ventilation floor plan maintained more comfortable than the house having ordinary floor plan by natural cooling effect of cross-ventilation.
