| In this study, to determine areas with high thermal stress in the city of Cheongju and properly respond to damage from heat waves, the scenarios of roof greening, cool roofs, cooling fog, clean roads, and urban green spaces were considered. Using the urban-scale microclimate analysis modeling method, it was determined if the heat wave damage reduction facility was effective in lowering the temperature or thermal comfort index. Cooling fog and clean roads, which are implemented on short-term scales, showed temporary temperature reduction effects using water, but also rose slightly with time delay while lowering the universal thermal comfort index UTCI. Long-term green and cool roofs have the effect of reducing the surface temperature by changing the albedo of the building’s roof surface. In the area with a cool roof, the temperature decrease was large initially, while the temperature increase was the weakest despite the increases in solar radiation and radiation during the daytime. Based on a detailed analysis of industrial complexes with the highest heat stress, the scenarios that lowered the UTCI were cooling fog, cool roofs, and urban forest creation. If these three scenarios are properly implemented in industrial complexes and surrounding areas, which are the highest heat dissipating areas in Cheongju, the urban thermal environment and energy consumption will be improved. It is expected that the results of this study will be used to increase the sensitivity of decision-making processes for installing heatwave reduction facilities and heatwave response policies. | |
