OGC standard CityGML opens up new applications in the energy simulation of buildings

The transition in the energy sector in Europe and other countries induces a strong need for calculation and simulation of all building energy demands, energy generation and energy supply. While building information models such as IFC focus on individual buildings and their neighborhood, and (2D) GIS on urban level and beyond, there is a gap for a 3D building model that suits the needs of an urban wide energy planning including simulation of demand, storage, and local infrastructure networks.

CityGML as a standard of the Open Geospatial Consortium (OGC) is a comprehensive open data model for modeling, storage and exchange of virtual semantically enriched 3D city and landscape models in different levels of detail. The OGC, the Special Interest Group 3D (SIG3D) of the Spatial Data Infrastructure Germany and the Stuttgart University of Applied Sciences have held a first workshop on the development of a CityGML Energy Application Domain Extension (EnergyADE).

The aim of the EnergyADE is to act as an information model for energy planning on urban scale as well as an interface to share information between existing energy planning and simulation systems. A consolidated version of a harmonized EnergyADE is expected to be finished until the end of 2014 and in addition, there are various efforts for a mapping between CityGML and IFC.

CityGML as a standard for modelling 3D city and landscape models opens up new applications in the energy sector of buildings

Against the background of a turnaround in the energy sector in Europe and other countries there is a strong need for the calculation and simulation of all building energy demands, energy generation and energy supply. While building information models such as IFC focus on individual buildings and their neighbourhood, and (2D) GIS on urban level and beyond, there is a gap for a 3D building model that suits the needs of an urban wide energy planning including simulation of demand, storage, and local networks.

CityGML as a standard of the Open Geospatial Consortium ( OGC ) is a comprehensive open data model for modelling, storage and exchange of virtual semantically enriched 3D city and landscape models in different levels of detail. The OGC, the Special Interest Group 3D ( SIG3D ) of the Spatial Data Infrastructure Germany and the Stuttgart University of Applied Sciences have initiated a first workshop to start the development of an Energy Application Domain extension (EnergyADE). The aim of the EnergyADE is to act as an information model for energy planning on urban scale as well as an interface to share information between existing energy planning and simulation systems (to build up a system of systems).
