Abstract

This study measured the Physiological Equivalent Temperature (PET) of the hottest day time in a day, in order to verify the characteristics of human thermal comfort in case of heat wave during summer time in each region, by subdividing the urban areas in accordance with the climatic characteristics with the use of Local Climate Zone (LCZ) as a method of classifying the type of urban climate and the land cover map, targeting the Homaesil residential development district in Suwon. In the results of measurement, the forest and paddy field showed the moderate heat stress while the urban park showed the strong heat stress. Other developed areas showed the extreme heat stress. Such results show the possibility of institutional utilization for the improvement of human thermal comfort through the verification of climatic characteristics and differences in each type of urban areas, and the efficient placement of green infrastructure and the planning of land use to cope with the heat wave even in the planning stage for the establishment of urban planning.

본 연구는 수원시 호매실 택지개발지구를 대상으로 토지피복지도와 도시기후 유형 분류 방법인 Local Climate Zone (LCZ)을 활용하여 기후적 특성에 따라 도시지역을 세분화하고, 각각의 지역에 대한 여름철 폭염 시 열환경 특성을 확인하고자 하루 중 가장 더운 낮 시간의 열쾌적성을 측정했다. 측정 결과 산림과 논은 중간 열스트레스 값을, 도시공원은 강한 열스트레스 값을 나타냈으며, 기타 시가화 지역은 극한 열스트레스 값을 나타냈다. 이러한 결과는 도시지역의 유형별 기후적 특성과 차이를 확인하고, 도시계획 수립 시 계획단계에서부터 폭염을 대비한 토지이용의 구상 및 그린인프라의 효율적인 배치를 통해 열환경 개선을 위한 정책적 활용 가능성이 있음을 보여주었다.
