Abstract: As complexity in terms of pressure, e.g. to achieve time-framed global goals regarding climate change, diversity, e.g. of different themes or involved stakeholder, duration, e.g. of planning phases as well as corresponding planning horizons, is continuously on the rise, an integrated planning of urban (energy) systems has to be increasingly supported by IT-based planning and simulation tools. Up to now various existing simulation tools share a common problem as their capabilities rely on the data that is available for the local situation that shall be analyzed. Here, there often is a lack of comprehensive and up-to-date information on the build environment and energyrelated infrastructure as needed for input to the energetic simulation. On side of assessment methods typology data can help to fill the information gaps in available local data. However, again due to missing common data the compilation of these typological information on base of literature data is often individually done by experts in a locally specific manner that can’t be generalized. In order to address this problem field an ongoing research project pursues solutions for energetic urban simulation that base to the most extend on established standards. For the side of simulation technology on the level of building there has been vast developments in standardized and therefore interchangeable performance simulation technology within the framework of Modelica. As effort to buildup component libraries for the building performance simulation on a common base has been accomplished to some extend and is currently further optimized (c.f. IBPSA Project 1), the next frontier for developed libraries is to be applied in the simulation on the urban scale. On side of planning parameters bidirectional exchanged with simulation by means of extended CityGML-models builds the target regarding standardization. In this contribution a tool chain to support urban energy planning following this approach is presented.
