Presentations and Minutes

Welcome on behalf CSTB + Presentation of Activities of CSTB relying on CityGML Pascal Schetelat (CSTB) Presentation: PDF file of the slides Brief welcome Presentation of CityGML related work at CSTB unification of data models across domain specific studies developing custom ADEs for specific simulation tools’ needs, integrated to public ADEs when worth sharing biggest challenge: filling the gaps in data! Not reading it! Presentation of EveBIM software: reads IFC and cityGML (visualization purposes) many plug-ins for simulation freely downloadable on CSTB website CSTB Wishlist : a nice way to store ADE files in database a material module independent from energy ADE for cross domain studies -> not planned as yet unique ID reference for materials, collecting all domain specific parameters. On independent ADE -> on unique ID, ongoing work: referent = Thomas Kolbe idem, independent module for occupancy module -> not planned as yet
Report on the last semester (All WG leaders) Romain Nouvel (HFT Stuttgart) Presentation: PDF file of the slides Mentimeter quiz on: CityGML Energy ADE for you... Priorities for the next semester? : Make ADE test cases! Activity : Activity (measured on GitHub activity) is not constant; attendance to workshops is diminishing -> Would be nice to integrate work on energy ADE into projects, to have time and budget (work on ADE is not only standardization, but also interoperability) Many companies/countries are interested, but not necessarily active… -> Build interest through common publications for example Organisation : Wiki page: http://en.wiki.energy.sig3d.org 4 working groups with each 2 coordinators: Building physics: Romain & Mostafa Occupancy: Piergiorio & Giorgio Energy use and systems: Moritz & Silvia Time-dependant data: Alexandru & Kanish Technical committee in charge of XML schema: Joachim & Elisa Problem: there are often collisions between several issues Process: General: Issue created on Github Discussion ongoing, including a feedback from technical committee which has the global overview When discussion has found a consensus, add a “validated by WG” tag TC: Go to modelisation WG: actualize guidelines in the corresponding Github branch, including examples (doc/guidelines/Guidelines_EnergyADE.md, linked to figures in /fig) If need be: feedback from WG, changes by TC Github branches: Master branch = current validated version (today 0.8) When new branch (0.9) is stabilized (including guidelines), merge it to master branch NB: make new branch the default branch, but make the releases clearly visible on the frontpage Deadlines: mid-June: Github issues July: draft modelisation (Joachim) end-July: edit guidelines by WG (in parallel to modelisation) -> edits can be suggested directly into issues, so update is easy and quick a validation by all Mid-August: release of .xsd and guidelines Timeline for v1.0 : Before v1.0 there needs to be testing on real case tools… we need to accelerate on this in upcoming semester Proposals for modeling changes: Energy and system Q/ how to integrate simulation data? With Dynamizer module? Q/ management of codelists -> WG Apache license 2.0: Objective: protect our development, before it becomes an OGC standard Implications: anyone can use it, but need to integrate a specific text in header of documents (text quotes license and participant organisations with email contact) In order to go forward: Mustafa needs an explicit email agreement from each participant partner We need to agree on which organizations should be quoted in license (some participate to workshops but are not active, and some are active but do not participate to workshop) -> criteria proposal: regularly active on Github, reactive to emails (to be discussed further) Next meeting: Karlsruhe Options: 7, 8, 14, 15 November; 4, 5, 6, 7, 8 December Provide feedback to Romain on availability
Codelist concrete implementation Luca Giovannini (Dedagroup Public Sector & Utilities) Presentation: PDF file of the slides Working document on Google doc To do : Link to be added in GitHub readme Add a column “source” or “reference” Verify English translations Discuss unclear points Designate one person per language Discussion: BuildingTypeValue: Source: physical architecture typology comes frome TABULA project (now EPISCOPE) Issues: Make all labels identical: “XX building” Agree on high-level values -> plan an online meeting (Usman, Lydia CSTB, Emilien CSTB, Romain, Mariam, Joachim) Create expanded version (subvalues) for more clarity, precision? -> discussion on subvalues for next version CurrentUseValue: Source: Geomark city project See: CityGML codelist (Joachim to provide URL link) EnergySourceValue: Work on definitions needed -> all OccupantTypeValue: Work on definitions needed -> all OfficialAreaReferenceValue: Issue: not one national way to measure net surface -> should use possibility to define surface type
Store Energy Simulation results / inputs Joachim Benner (KIT) Presentation: PDF file of the slides Issues : Automatic generation of a diagram legend -> optional character string “thematicDescription” in TimeSeriesProperties (a dataType does not have a gml_name!) WeatherData -> need to be aggregated in a WeatherStation Q/ generalization to noise etc.? -> this is domain specific (inside Energy ADE) Q/ what if sensor inside building? -> not weather… Q/ context can sometimes have a big impact on measurements -> add a human-readable description for all additional info Q/ will there be a Sensor module in CityGML 3.0? -> No… EnergySimulationResults: metadata, link to raw data, … Q/ what conceptual difference between simulated and measured data? -> none, but it is difficult to work on too generic feature types -> Pb: some simulation outputs are inputs for other simulations -> this is simulation metadata (input data, simulation model used, date…) Add a code snipet, or contact person? Value: can be Measure or TimeSeries -> include only aggregated values in CityGML? -> Pb: co-simulation needs the extensive simulation results -> Need to look into the Sensor ML (with metadata, sensor can be real or virtual) + Observations ML (supports external references), which are parts of Sensor Observation Service -> dedicated WG/online meeting on simulation results and measurements (Kanish, Joachim, Pascal, Romain) + create a milestone on Github linked to all related issues, with definition of both “measurements” and “results”
