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:
- 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:
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”
