박물관 증축에 의한 기능의 공간 및 시각적 위계 변화 분석 연구

Abstract

(Background and Purpose) As museums are a source of national competitiveness, the Korean government has prepared mid-to-long-term plans for promoting museums. Constructing more museums is part of the national plan to encourage the public to visit and utilize them, yet existing museums require additional space for exhibitions due to the increase in collections over time. In response, constructing museum extensions is a common solution to this problem. However, there is a lack of research and data related to museum extensions. Therefore, this study analyzed changes in the spatial and visual hierarchy before and after extending an actual museum to establish basic data for future museum extensions. (Method) Changes in the spatial and visual hierarchy before and after extending a museum were analyzed. Space syntax and visibility graph analysis (VGA) were used to derive index values related to connectivity, global integration, local integration, and clustering coefficients. A hierarchical analysis of the museum extension’s functions was conducted based on the top 10% of values for each indicator. (Results) The results were as follows. 1) Except for design intentions in special circumstances, the museum extension did not cause a significant change in connectivity, which is related to space utilization. Extension buildings are generally used for sub-functions. 2) Museum extensions tend to increase the usage, accessibility, and awareness of public spaces, such as the halls and lobbies, which change the simple exhibition function of museums to various functions of social communication. 3) The results of the VGA related to connectivity and clustering coefficients (visual hierarchy indicators) showed that the visual openness of public spaces increased after the museum extension. In addition, the results of the VGA related to local integration (an indicator of accessibility) showed that the ratio of grids with the top 10% of values changed to public spaces after the extension, which will emphasize the function of these spaces in the future. 4) In summary, the spatial and visual hierarchy of public spaces increased after the museum extension, which should be reflected in the design of future extensions to emphasize the role of social communication. (Conclusions) This study is significant, as it established basic data for future museum extensions by analyzing the spatial and visual hierarchy before and after extending an actual museum. However, it has limitations, as only two-dimensional analyses using space syntax and VGA were conducted. Therefore, further research should adopt various methods in the future.
