초록

최근 들어 서울시를 비롯한 대도시에 건립되는 초고층건물은 주변 공기의 대류를 변화시켜 난류현상을 유발하여 빌딩바람과 도시열섬 및 대기오염 물질 집적 등 주변 환경에 영향을 미치고 있다. 그 중에서도 고층건물의 주변지역의 기온의 공간적 변화는 환경 경사가 심한 것으로 판단된다. 이에 본 연구에서는 서울시 강남구의 초고층건물 지역과 인접 지역의 기온차이를 파악하고자 2008년 3월 16일부터 2009년 3월 15일까지 고정관측과 이동관측을 수행하였다. 타워팰리스(TPL)와 숙명여고(SMG)의 거리는 불과 200m이지만 두 관측지점의 연평균 기온차는 $0.7^{\circ}C$로 관측되었고, TPL의 열대야 일수는 13일, SMG는 5일이었다. TPL의 기온이 다른 곳보다 높은 것은 고층건물에 의한 도로협곡으로 인해 sky view factor가 현저히 낮아 장파복사의 대기 중 방출이 억죄되 도시열섬현상을 가중시키고 냉난방의 단위면적 당 전력 수요가 높아, 이로 인한 인공폐열이 도로협곡에 갇혀 고층건물 지역인 TPL의 열섬현상이 인접 지역보다 높은 것으로 관측되었다.

In Seoul, skyscrapers are built in commercial zones known as residential-commercial complexes, which cause such environmental problems as urban heat islands(UHI) and air pollution. To investigate air temperature differences in areas near skyscrapers at Gangnam-gu, Seoul, South Korea, fixed air temperature observation and traverse observations were performed from March 16, 2008 to March 15, 2009. The annual mean air temperature at Tower Palace(TPL) was higher than that at Sookmyung Girls' High School(SMG) by $0.7^{\circ}C$, although the distance between the two observation positions is only 200m. The number of tropical nights at TPL was 13, while that at SMG was 5. The higher air temperature at TPL was due to a significantly lower sky view factor(SVF), which prevented long-wave radiation from emitting into the sky. The highest air temperature increases near TPL occurred on summer nights because of the high-electricity consumption value of $70.22Wh/m^2$ for the TPL block in August due to air conditioning for cooling. It is concluded that the warm air pocket centered on TPL.
