Abstract
Abstract Urban Heat Islands (UHI) affect building energy use in many cities worldwide. The correlations between UHI and building energy use have mostly been studied via city-scale modeling simulations, making validation of the obtained results challenging. In this study, we use clustering and statistical methods to examine the relationship between various indicators of UHI and building energy use, utilizing archived empirical data on energy consumption in office buildings across the entire country of South Korea. Our findings reveal considerable differences in UHI behavior across provinces and cities in the country. These variations are driven by a complex interplay of factors related to geographic locations, urbanization levels, and the topography of the provinces. These results suggest that mitigative efforts for UHI in South Korea should consider targeted measures tailored to specific locales. We also identify strong positive correlations between various UHI indicators, particularly monthly average Urban Heat Island Intensity (UHII) and cooling energy consumption in office buildings. However, the relationship between UHII and heating energy consumption was largely non-existent. These findings offer an empirical foundation for the development of efficient and inclusive policies that promote livability in urbanized areas.
