Ospitaletto District Heating Expansion – Building Heat Demand and Network Dataset

This dataset provides georeferenced building-level annual heating demand estimates and district heating network geometry for the municipality of Ospitaletto (Brescia, Lombardy, Italy), developed to assess expansion opportunities for an existing 5th Generation District Heating (5GDHC) network. The building heat demand layer (Ospitaletto_heat.gpkg) covers 1,957 buildings with 17 attributes including footprint area, building height and volume, S/V ratio, functional use (residential/non-residential), INSPIRE-based typological class (SFH, s-MFH, l-MFH), estimated annual heating demand (MWh/year), distance to the DH network, and priority selection flags under two criteria. The DH network layer (DH_ospitaletto_network.gpkg) contains 21 pipe segments of the existing network. Both layers use the EPSG:3035 coordinate reference system. Heating demand was estimated through a data-fusion methodology combining building geometry (OpenStreetMap, cadastral data), climate inputs (Heating Degree Days, Southern Continental zone), energy consumption density benchmarks (INSPIRE for residential, Hotmaps for non-residential), and available metered consumption data for calibration. Network expansion priorities were assessed using two criteria: Criterion A selects buildings by maximizing the ratio of annual demand to distance from the network (kWh/y/m); Criterion B applies a 250 m buffer around the existing network and filters by minimum demand threshold (100 kWh/y).
