Transitional Characteristics of Old Residential Areas in Downtown through Context Simulation - Focused on the 39~134 Namju-Dong outside South Gate of Cheongju, Korea -

컨텍스트 시뮬레이션을 통한 도심 옛 주거지의 변화 특성 - 청주시 남문 밖 남주동 39~134번지 일대의 블록을 중심으로 -

With the need for gradual regeneration research that emphasizes existing contexts in the face of indiscriminate development of old urban dwellings, this study aims to examine the transitional characteristics of spatial, visual, and thermal environment from the 1960s to the 2020s focused on the Namju-dong outside south gate of Cheongju through context simulation. In the simulation of spatial change from the 1960s to May 2022, the expansion and construction of buildings have been carried out in the form of old street networks, alleys, and individual lots except for the area around the opening road, In the simulation of visual change, Namju Sangga-ro, Jungang Park Road, and alleyways in the north-south direction still reveal the old scenery, the Gagujeom-gil and Eunhaengnamu-gil in the east-west direction have three or four stories that are 1 to 1.5 times the width of the 6~8m road. In the simulation of thermal environment, wind paths that flowed between narrow alleyways and yards disappeared into the middle-story buildings connected to the opened road and the surrounding high-rise buildings, and the wind speed of 2-3m/s rose to more than 5m/sec. This study remains at the basic production of LOD 1 and 2 in building modeling work. In the future, it can be used as a guide for more convincing gradual regeneration measures by modeling the materials and detailed elements of buildings in stages of LOD 3 and 4, and the planting, fences, and gates in stage of LOD 5.
