[E2-02] Analysis of Thermal Environment of Greening Vacant Houses in Old Downtown Metropolitan Areas: A Case Study on Busan Metropolitan Cityclear
キーワード：vacant housing, greening, thermal environment, ENVI-met, old downtown
This study investigates land cover characteristics of vacant lots in the densely populated residential areas of Ami-dong and Chojang-dong, located in Busan Metropolitan City's old downtown area. Furthermore, it evaluates the thermal environment mitigation effects of greening vacant lots after demolition vacant houses using ENVI-met simulation. The simulations were conducted on four zones, considering building density and slope direction, and four greening scenarios were evaluated within these zones. The study found that about 83% of vacant lots were left neglected with concrete pavement. Compared to the current scenario, the concrete scenario showed a 0.51℃ increase in Physiological Equivalent Temperature (PET), indicating significant deterioration in the thermal environment. Conversely, planting trees led to notable improvements, resulting in a 0.65℃ decrease in PET. This study provides crucial data to support intelligent greening strategies for sustainability.
