Building-level residential material stock and embodied carbon dataset for South Korea

Data Description: Building-level material stock and embodied carbon dataset (South Korea) Overview This dataset contains spatially explicit, building-level estimates of residential material stock (MS) and cradle-to-gate embodied carbon (EC) for South Korea. The data are primarily provided as an OGC GeoPackage (.gpkg), integrating official building footprints with attributes derived from administrative registries and the modelling workflow of the study. The public release excludes construction year, administrative identifiers, and other raw registry helper fields. It therefore provides only the gap-filled floor-area variables, the final archetype labels, and the final building-level material-stock and embodied-carbon estimates used in the released study outputs. In addition to the regional public GeoPackages, the study also provides tabular datasets and model-parameter tables: • national_300m_residential_stock_EC_v4_5_8.tif: Total residential material stock and embodied carbon in each 300 m cell grid. • provincial_summary_17.csv: Province-level summary statistics for the 17 provinces, including total and per-capita material stock and embodied carbon. • EPD_GWP_factors.csv: Material-level cradle-to-gate GWP factors used in the embodied-carbon calculations. Coverage The dataset covers all building polygons in [REGIONNAME] contained in the final study dataset. Residential outputs are zero for buildings that were not identified as contributing to the residential stock. File Specification File Name: [REGIONNAME]_residential_stock_EC_v4_5_8.gpkg Format: OGC GeoPackage Coordinate Reference System (CRS): EPSG:5179 Attribute Table Schema The attribute table includes the following fields for each building polygon: Field Name Description Unit ArcheType Building archetype used in the stock and embodied-carbon estimation. – ResidFloorArea_gf_m2 Above-ground residential floor area. m² Stock_GF_Resid Estimate of total residential material stock. kg Stock_GF_Concrete_Resid Estimate of concrete-related material stock. kg Stock_GF_Steel_Resid Estimate of steel-related material stock. kg EC_GF_Resid Estimate of total cradle-to-gate embodied carbon. kg CO2-eq EC_GF_Concrete_Resid Estimate of concrete-related cradle-to-gate embodied carbon. kg CO2-eq EC_GF_Steel_Resid Estimate of steel-related cradle-to-gate embodied carbon. kg CO2-eq Height_gf_m Gap-filled building height m GrossFloorArea_gf_m2 Gap-filled Gross floor area m² Note: The GeoPackage may also contain the system-generated field fid. This is an internal GeoPackage feature identifier rather than a study-defined scientific variable. Methodology Summary Building footprints from the Korean Roadname Address Database were linked to official building-registry information through a hierarchical address-matching workflow. Missing or incomplete building attributes were then gap-filled using the study workflow, which combines administrative fallback procedures, satellite-based deep learning for building-height inference (BHE-Net), and statistical models for downstream attribute estimation. Building-height variables are not included in the public release because of licensing constraints. Material stock was estimated using the study’s final archetype-based material-intensity model. The released stock variables summarize total residential stock and its concrete-related and steel-related components. Embodied carbon was calculated under a cradle-to-gate system boundary (A1–A3), using material-specific emission factors compiled from South Korean EPD-based and static factor sources in the final workflow. Usage and Licensing This dataset is intended for research on building stocks, urban metabolism, circular economy, material accounting, and sectoral decarbonisation.
