Abstract

This study of the school's outdoor space for relaxing and activity of the two most numerous students, high heat and low heat with a green space, playground targets of thermal comfort indicators UTCI, PMV, WBGT using the thermal comfort students feeling compare the analyzed. The destination of this study, school facilities of Nam-gu, Namdong- gu, Incheon were studied and the investigation period was conducted from July to August. List of measurement, in the case of thermal comfort indicators, UTCI, PMV, WBGT was measured in the case of green, ratio of green coverage and GVZ was measured. GVZ analysis were as follows: A school ($4.71m^3/m^2$) B school ($3.34m^3/m^2$) C school ($0.38m^3/m^2$). Comparative analysis of the results of thermal comfort indicators by schools, UTCI was Green space $26.15{\sim}31.38^{\circ}C$ and playground $40.66{\sim}42.94^{\circ}C$, PMV values were 1.76 to 2.66 as a green space. WBGT was Green space $26.15{\sim}31.38^{\circ}C$, playground $31.67{\sim}34.53^{\circ}C$. Comparative analysis of the results of thermal comfort indicators UTCI, PMV, WBGT all A school, B school, C school, on the green space was comfortable levels more than playground. The results of the school type thermal comfort and green correlation analysis of thermal comfort UTCI, PMV, WBGT all solar radiation, globe temperature, and a positive correlation shown solar radiation, globe temperature is not comfortable, the higher was considered. UTCI, PMV, WBGT of thermal comfort indicator all ratio of green coverage, GVZ and negative correlation appears ratio of green coverage, GVZ was increased due to the lowering of the value of thermal comfort indicators was considered to be comfortable.

본 연구는 학교의 옥외공간 중 학생들의 휴식 및 활동량이 가장 많고, 높은 열과 낮은 열을 가지는 운동장 및 녹지공간을 대상으로 열적 쾌적성 지표 중 UTCI, PMV, WBGT를 이용하여 학생들이 느끼는 열적 쾌적성을 비교 분석하고자 하였다. 연구대상지는 인천광역시 학교시설(3개교)을 대상으로 하였으며, 조사기간은 2013년 7 ~ 8월까지 실시하였다. 측정항목으로 열적 쾌적성 지표의 경우 UTCI, PMV, WBGT를, 녹지구조는 녹피율과 녹지용적계수를 측정하였다. 학교별 녹지용적계수는 A학교($4.71m^3/m^2$) > B학교($3.34m^3/m^2$) > C학교($0.38m^3/m^2$)의 순이었으며 학교별 열적 쾌적성 지표를 살펴보면, UTCI는 녹지공간 $32.30{\sim}35.68^{\circ}C$, 운동장 $40.66{\sim}2.94^{\circ}C$, PMV수치는 녹지공간 1.76~2.66이었으며 운동장은 모두 3으로 나타났다. WBGT는 녹지공간 $26.15{\sim}31.38^{\circ}C$, 운동장 $31.67{\sim}34.53^{\circ}C$이었다. 3개 지표 모두 녹지공간 대비 운동장에서 매우 불쾌적한 수준이었다. 열적 쾌적성 및 녹지와의 상관분석결과, 열적 쾌적성 지표인 UTCI, PMV, WBGT 모두 일사, 흑구온도와는 정의 상관관계를, 녹피율 및 녹지용적계수와는 부의 상관관계로 나타났다.
