Notes

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:
  • 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”
