Linked Geodata: Improving Rooftop Photovoltaic Production Estimates through BIM-GIS Integration using Semantic Web Technologies
Accurately predicting rooftop photovoltaic (PV) electricity output is crucial for sustainable urban energy planning, yet current workflows that rely on 3D city models in CityGML Level of Detail 2 (LOD2) tend to inflate roof areas and, consequently, PV potential. This study develops and evaluates a proof-of-concept framework that integrates detailed Building Information Modelling (BIM) data in Ind
