This study notes that energy consumption in the domestic building sector recently accounts for more than 20% of the total final energy use, with residential buildings representing the highest share—approximately 54.9% as of 2024. This outcome results from multiple factors, including an increase in the number of households, diversification of housing types, and improvement in living standards, indicating that the residential sector has emerged as a key area in national energy policy and carbon-neutral strategies. Therefore, this study aims to analyze temporal changes in energy consumption and energy use intensity (EUI, kgoe/㎡) for detailed residential building types——single-family house, lodging house, multi-family house, low-rise house, medium-rise house, and apartment house—using multi-year integrated data from 2018 to 2024. Through this analysis, the study seeks to identify the effects of housing-type transitions on energy consumption structures and to provide foundational data for developing housing-type-specific reduction strategies and low-carbon residential policies.
