종합병원의 유연한 내부변화를 위한 설비 공간 계획

Abstract

Purpose: This study aims to identify the importance of building service space planning in securing spatial flexibility within general hospitals in response to changes in medical environments and societal demands. Hospitals undergo continuous expansion and remodeling due to advances in medical technology, regulatory shifts, and evolving patient needs, with service spaces playing a critical role in the reallocation and expansion of internal functions. Focusing on the National Cancer Center and Seoul National University Bundang Hospital—both of which have experienced large-scale extensions and comprehensive restructuring—this research analyzes the changes in air handling units and utility shafts, and their relationship to internal space reorganization. The ultimate goal is to derive planning strategies for service spaces that enhance adaptability and support functional modifications in future hospital designs. Methods: This study analyzes two general hospitals that underwent large-scale extensions and restructuring, examining changes in AHUs and utility shafts to assess their impact on spatial flexibility. Results: The conclusions of this study are as follows: First, to secure spatial flexibility within hospitals, service spaces should be recognized and planned as fixed elements from the initial design stage. Second, vertical shafts should be concentrated near staircases, elevators, and public corridors to minimize the scope of modifications during future departmental rearrangements. Third, adopting a one-floor-one-AHU system allows functional changes through simple duct extensions or reductions without additional vertical shafts. Finally, utilizing dry areas or external piping reduces the footprint of internal service spaces and secures usable floor area, forming a key strategy for flexible adaptation to future hospital expansions or functional changes. Implications: In the initial hospital design, it is possible to plan a spatial structure that allows flexible departmental arrangements and enables adaptable internal modifications during large-scale remodeling.
