DBSM R2025: EU Digital Building Stock Model update including satellite-based attributes and rooftop photovoltaics potential

The EU Digital Building Stock Model (DBSM) is designed to provide a comprehensive and detailed geospatial database of individual buildings within the European Union, focusing primarily on their energy-related characteristics. This new iteration of the geospatial dataset, DBSM R2025, offers significant enhancements over its predecessor, including more precise and detailed building polygons, as well as an expanded collection of building attributes and a complete EU-27 geographic coverage (including Azores, Madeira, and Canary islands). These attributes encompass a range of factors such as building height, compactness, epoch of construction, use type and rooftop solar photovoltaic potential. The technical report linked below provides an in-depth examination of the methodological approach employed in the development of these enhancements and discusses the validation processes undertaken to ensure the accuracy and reliability of the data. The scientific paper on Nature Energy (now in press), will provide a description of the methodology followed for the estimation of the rooftop photovoltaic metrics along with insights on the potential to cover EU electricity needs and policy targets.
