Today, the main use of 3D building models is for visualisation purposes. However, such models also have huge potential for supporting the 'smart city' concept. Disaster management, 3D cadastres, energy assessment, noise & pollution monitoring and visibility analysis could all benefit from enriched 3D building models. To demonstrate this potential, the authors present three case studies in which 3D building models have been enriched with non-spatial data. The datasets can be visualised and managed online within a web-GIS platform.
