Abstract
As urbanization progresses worldwide, high density development emerges around major cities. Korea, with an 81.9% urbanization rate (2021), is no exception, especially in Seoul. The central and Gangnam districts have strong street canyon features due to complex land surfaces, urban morphology, and heavy transportation. These factors, combined with polluted traffic emissions, threaten urban residents' thermal and pollutant exposure. Understanding vulnerable areas in terms of microclimate and ventilation is vital for livability, sustainability, and resilience in urban planning. Using Ladybug & Dragonfly in Rhino's Grasshopper, we analyzed the correlation between street canyon morphology, microclimate, and the urban heat island index. The study focuses on the geometric characteristics of urban spaces, particularly high-rise buildings and roads forming street canyons, and their impact on microclimate (thermal comfort). The findings contribute to effective management, fostering sustainable urban forms and redeveloping street spaces with consideration for the microclimate environment.
