| Abstract |
This study explores the relationship between building-level vacancy rates and the physical, locational, and facade characteristics of commercial
buildings in a university district. The sample consists of 97 commercial buildings located between Pusan National University and Pusan
National University Station, limited to buildings facing roads at least 6 m wide. Field surveys, building register data, GIS-based
walking-distance analysis, and facade measurements from frontal photographs were used. Variables included gross floor area, total floors,
vacant-storey level, vacant-unit area, year built, primary use, walking distance to the nearest subway exit and bus stop, low-floor and
high-floor sign-area ratios, low-floor and high-floor window-area ratios, facade form, exterior material, and color saturation. The results show
that smaller buildings and lower-floor vacancies are more strongly associated with higher vacancy rates. Transit distance showed limited
explanatory power within the same living sphere. Among facade variables, the low-floor sign-area ratio showed the most consistent association
with vacancy rates, while other facade variables showed relatively limited explanatory power. These findings suggest that vacancy in a
university commercial district is better understood through the combined effects of building scale, lower-floor vulnerability, and lower-floor
facade visibility. |
