Abstract

Purpose: The aim of this study was to analyze the reduction in the Urban Heat Island (UHI) effect by site type according to the reflectivity of the roof surfaces. Methods: First, the intensity and current state of the UHI effect in Seoul was analyzed using Automatic Weather System (AWS) data. Subsequently, after categorizing the studied sites by type into middle and low-rise residential site (Gwangjin-gu), high-rise residential site (Songpa-gu), and commercial site (Seocho-gu), the temperature reduction effect was analyzed according to the reflectivity of the roof surfaces using simulation. Results: The temperature reduction in the middle and low rise residential site was more significant than that in the high-rise and commercial site due to the difference in the density of the buildings. Furthermore, the temperature reduction in summer was more significant than that in winter.
