Analysis and Improvement of Building Energy Data Collection Systems for Green Remodeling of Aging Small Scale Residential Buildings in South Korea - Comparative Review of International and Domestic Practices
Year: 2026
Type: preprint
Abstract: This study aims to analyze domestic and international building energy data collection systems and propose strategies to promote renewable-energy-based green remodeling in aging small-scale residential buildings in South Korea. A five-step review of the literature and relevant documents was conducted to examine European policies and financial support mechanisms, hybrid geothermal–photovoltaic demonstration projects, and building energy data infrastructure. Domestic conditions were assessed by examining the green remodeling system established under the Green Building Construction Support Act, the policies and regulations of five metropolitan cities, and public data systems, including Seumteo, V-World, Architecture HUB, and the National Building Energy Database. Spatial information was also examined using geographic information systems (GIS). The comparison identified six structural problems: the absence of systematic data collection, a policy focus on public buildings, insufficient renewable energy data, inadequate integration of passive and active systems, limited economic feasibility, and a lack of post-retrofit performance verification. Six corresponding improvement strategies are proposed: mandatory monitoring, national demonstration programs, diversified financing mechanisms, one-stop service centers, integrated design guidelines, and phased regulatory mandates. Finally, the study highlights the need to establish an integrated, multilayered data structure at the building level.
