Energy building spatial data interoperability allows us to explore interoperability within domains, where specific data and knowledge paired with established and emerging systems pose various challenges to interoperability and data integration. The topic is hotter than ever before with the current sky-rocketing energy prices. It addresses how to build robust platforms for a specific community that bridges all the way from raw data to decision-makers. The participants and their roles are presented in the figure below:
The Interoperable Simulation and Gaming (ISG) Year 2 initiative will build on momentum established during the recently completed ISG Sprint (year 1), documented in the ISG Sprint Engineering Report. Additional results are demonstrated in this YouTube Playlist. This OGC Innovation Program initiative will advance geospatial interoperability of systems exchanging 3D content. OGC is working with the Khronos Group and various OGC Working Groups to advance interoperability of 3D geospatial and computer graphics using OGC CDB, Khronos glTF, and related 3D standards. Prototyping work is advancing interoperability for Geospatial Intelligence (GEOINT) Processing, Exploitation, and Dissemination, as well as open standard interfaces critical to enabling novel combinations of emerging technologies to bridge Special Operations Forces (SOF) capability gaps.
In the project NeqModPlus we developed models and tools to simulate energy demand and different energy generation systems of buildings and city quarters that can help reach the goal of zero carbon emissions. One of the case studies is a new building of the inner-city campus of the University of Applied Sciences in Stuttgart, Germany. Here we have measured data and can compare this with our models. In this visualization, we compare the measured heating demand with the results of two different simulation models that vary in their complexity. The complex model is a dynamic calibrated white box model that is described in ; the other is a steady-state simulation  according to German norms DIN V 18599 and VDI 4710. Both simulations include detailed building physics data as well as locally measured weather data; the steady-state simulation also uses the calibration results of the dynamic model for temperature setpoints and schedules.
The goal of the Sprint is to advance the use of relevant OGC and Khronos standards in the modeling and simulation community through practical exercise and testing of the draft specification produced by the 3D Data Container and Tiles API Pilot. Of particular interest is the handling and integration of glTF models coming from multiple sources. There is secondary interest in the spec’s implementability, consistency, completeness, and maturity. Implementation experiences obtained from the Sprint will advance the interests and work of the OGC Interoperable Simulation and Gaming Domain Working Group (ISG DWG) and of the OGC Standards Baseline in general.
