Abstract

This study investigates key drivers of energy use in Korean hospital-grade medical facilities using public datasets. After preprocessing data from 932 facilities, type-specific multiple regression models were developed with stepwise selection. Annual total energy use served as the dependent variable, while gross floor area (GFA), number of doctors (DOC), elevators (ELV), floors (FL), and beds (BED) were candidate predictors. GFA and DOC consistently emerged as major determinants, with ELV influencing general hospitals, and FL and BED affecting long-term care hospitals. Adjusted R² values ranged from 0.92 (general hospitals) to 0.41 (psychiatric hospitals). The negative ELV coefficient likely reflects multicollinearity with GFA rather than a true inverse effect. These results demonstrate that public data can support practical, easily updated benchmarking, and suggest future gains from incorporating operational and climatic factors.
