Abstract: Urban Building Energy Modelling (UBEM), an analytical method to comprehensively represent buildings on an urban scale, incorporates multiple data formats, modelling techniques and simulation methodologies. Though widely used, UBEM-based formats (such as CityGML) often lack the essential information required for energy performance simulations. An archetype-based enrichment technique suffices for the lack of required parameters, but their reliance on statistical data often restricts precise enrichment for a building's energy-specific parameters. Therefore, this paper presents an opensource CityGML Enrichment Tool (CityEnrich), enabling users to manually enrich CityGML building models and exchange enrichment data in the form of Energy ADE. The presented paper highlights CityEnrich's technical implementation and demonstrates the tool's applicability in UBEM.
