Aim of the workshop

The OGC CityGML SWG, the SIG 3D, and Hochschule fuer Technik Stuttgart will host a joint workshop to gather requirements, ideas, suggestions, and positive as well as negative experience from CityGML users, data producers, software vendors, and scientists developing and using a CityGML Energy Application Domain Extension. Aim of the workshop is to discuss and define a harmonized version of a CityGML EnergyADE and other development tools like libraries for wide spread use in the development of applications in the energy sector. The workshop will take place on the 27th of May, 2014 in Stuttgart, Germany. Further information on the venue can be found here: Venue.

In the recent years many research groups, companies, and users intensively worked with CityGML on energy topics. In order to promote the use of CityGML in the energy sector e.g. for individual, quarter wide or city wide computations and simulations a coordinated and harmonized version of a EnergyADE is desirable. Participants are invited to communicate their experience in short presentations and to introduce their concepts or modifications or share their experience gained from practical application of CityGML in the energy sector.

Agenda and Addressed Topics

  • TUESDAY, 27 May 2014
    • 10:00-10:20 Welcome address from the organizers
    • 10:20-12:00 Overview over CityGML based activities in the energy sector (data models, simulation and development e.g. libraries )
    • 13:00-17:00 Discussion about the development and harmonization of a CityGML Energy Application Domain Extension

The detailed agenda can be found here: Agenda of the Workshop.
Further information on each topic can be found here: Workshop Topics.

Who should participate

If you are a CityGML user, data producer, software vendor or a scientist working on energy topics based on CityGML, you are encouraged to participate in the workshop.
If you are involved in simulations but not yet familiar with CityGML and interested in an interoperable and compatible exchange model for city simulations you are also welcome.
The organizers will contact a number of individuals and groups from which they know about their CityGML activities in the energy sector and ask them for presentations soon if not done.

If you are developers/users of urban energy simulation models, we would like also to ask you 2-3 slides about the energy simulation model (which physical model? is it a standard?), the data model (UML Schema) and the possible building data libraries you used. Please send us these slides before the 19th of May (Romain Nouvel ). We would integrate this information in a comparison study during the morning session (“Review of urban energy models and their data requirements”). .

Because of the number of active participants, we won’t have enough time unfortunately for a presentation from each participant about its recent developments on urban energy model. We rather want to privilege an open discussion after noon. Nevertheless, if you want to send us presentations (pdf format) relevant for the common development of a CityGML ADE Energy, we will release them on the wiki of SIG3D.

As proposal and example of Energy ADE for the discussion block, the organization committee provide the HFT Stuttgart and TU Munich Proposals for an EnergyADE


Registration is closed. Thank you for your comprehension.

Costs of participation
