Abstract |
This study examined the impacts of compositional factors and three-dimensional physical environments on surface temperature in the 340 apartment complexes in Seoul, Korea, using the satellite image data of Landsat8. The results indicated that compositional and three-dimensional physical elements are important factors that affect surface temperatures in apartment complex. The lower building footprint, the higher proportion of green space, and more shadows were critical factors for the lower surface temperature. In addition, natural environment such as wind speeds, slope, hillshade, and building direction showed statistically significant relationships with surface temperatures. Regarding threedimensional variables, layout variables of apartment complex showed statistically significant relationships. In particular, apartment complexes with a closed layout were more likely to show higher surface temperatures than those with an open layout. In addition, this study found that surrounding environments of apartment complex such as built area ratio and distance to green space are strongly associated with surface temperatures. The analysis results will be helpful to develop mitigation strategies for the lower surface temperature and to improve thermal environment of residential apartment complexes. |
