초록

본 연구는 컴퓨터 모델링의 결과를 실측자료 보정없이 이용하였을 때의 문제점을 조사하기 위해, 작은 도시공원을 대상으로 실측자료와 컴퓨터 모델링 결과를 비교 분석하여 보았다. 컴퓨터 모델링 결과는 실측자료에 비해 미기후 요소인 기온과 풍속에서는 과소예측을 보였으며, 상대습도와 평균복사온도에서는 과대예측을 하는 것으로 나타났다. 그 차이는 인간 열환경지수인 PMV와 UTCI에서 최대 2.3 PMV와 4℃ UTCI의 차이를 보였다. 그러므로, 인간 열환경지수 (열쾌적성) 연구에서 컴퓨터 모델링을 이용할 때는 반드시 실측자료를 이용한 결과보정 과정을 거쳐 도시와 조경계획 및 디자인에 적용되어야 할 것이다.

For investigating restriction in the use of computer modeling results without adjusting them with measured data, this study analyzed and compared microclimatic aspects and human thermal sensation between in situ measurement and computer modeling using ENVI-met in and around a small urban park of downtown Changwon in May, 2012. In the results, ENVI-met underestimated air temperatures and wind speeds than the measured ones and overestimated relative humidities. In the radiation analysis, ENVI-met overestimated solar radiation from the sky hemisphere and terrestrial radiation from the ground hemisphere and underestimated terrestrial radiation from the sky hemisphere. Also, the differences of mean radiant temperatures with the measured ones reached up to 19.6℃ which could create an 1.2 PMV difference. ENVI-met overestimated up to 2.3 PMV and 4℃ UTCI at 12:00. The difference was shown clearly in PMV than in UTCI. Therefore, when computer modeling is used in urban microclimate and human thermal sensation (comfort) studies the modeling results should be compared with measured data and adjusted adequately to adopt the results to urban and landscape planning and design.
