Presentations and Minutes

TOP 1: Welcome Address from the organisers

Prof. Thomas H. Kolbe (TU Munich)

Presentation: Structuring Information Framework

Current research projects taking place at TUM that are closely related to EnergyADE development:

  • Linking sensors and city models
  • Development of the Dynamics part of CityGML 3.0
  • Building a General Indicator Modelling (GIM) and how it can help in understanding building compositions and estimating heat energy demands
  • Demonstration of the Web-Client in visualising 3D City Models and how it can be used for heat energy estimation


TOP 2: Dissemination activities


All this dissemination information must be updated on the public wiki. The private part of the wiki is not useful anymore (all development process is centralized on the GitHub) and can be deleted.

ACTION (ALL) Include the latest dissemination materials (e.g. papers, presentations and posters) and attended conferences in the wiki: http://en.wiki.energy.sig3d.org/index.php?title=Main_Page&action=edit&section=4
ACTION (E. Casper) Make the Wiki fully public. Delete the community portal and forum

TOP 3: GitHub Use: XML Schema, Requests of Change and Guidelines

Olivier Tournaire

Olivier presented how to use the issue. Basically, there are some "developers" (TC comittee + WG leaders) and "users" rights (all others). Everybody can create and comment issues, and write in the guidelines. Developers may set the labels and Milestones.

Process of Issue / request of Change
The process of Issue / request of Change is fully centralised on the GitHub platform. The following process has been discussed and agreed:

  1. Open the Issue and labelling it with the concerned WG(s)
  2. Discussed internally in WG until the agreement
  3. Once agreed internally, recap in a final comment: the motivations + the detailed request of changes (integrated definitions, types etc.)
  4. Check by requested people (TC or WG). If not ok: start agiain from 2. If ok: label the issue accordingly ("Validated by the WG" and "Validated by the TC"), and set the corresponding Milestone
  5. Once integrated in the UML Scheme and agreed with the WG, close the issue


Guidelines
Esteban Munoz presented how everybody can edit Guidelines on the Github: file Guidelines_Energy.md

GitHub open or private?
Calling for making the Github platform totally accessible to non-registered. Pros:

  • Get new fresh out of the box ideas
  • Outreach and spread the word

Cons:

  • It will consume sometime to filter the ideas and make sure that it can really have a positive impact in the EnergyADE development

A vote has been held with 20 Yes's and 1 No. It has been decided to make the Wiki fully public, with a clear link to the Github platform which remain for the moment private. Interested users is to contact Olivier Tournaire (or one of the development committee) to get an access for the Github.

ACTION (Olivier Tournaire): Check if we can open the WGs without the development branch on the GitHub
ACTION (development committee): Olivier Tournaire (or someone from the development committee) may provide a tutorial for using the Github
ACTION (WGs): Contribute to the Guidelines on the GitHub

TOP 4: Work realised in WG Occupancy

Jean-Marie Bahu & Piergiorgio Cipriano (EIFER, Sinergis)

Presentation: EnergyADE Occupancy

Jean-Marie & Piergiorgio discussed the organisation of the WG, activites, request of changes for the EnergyADE v0.6, and what they have tackled within the last 6 months.
Piergiorgio demonstrated the usage of INSPIRE codelists.

Raised Issues:

  • Should we use stick to CityGML codelist or INSPIRE codelist
  • Should we use the INSPIRE registery
  • Where to put the number of watt per person
  • Giving that building is a system, then windows are systems also?
  • CityGML data availability and data availability in general
  • Codelist or enumeration?

IFC specifications are available online
CityGML data can be found at the CityGML official website

ACTION (KIT): Send link schema for OBXML to Occupancy WG
ACTION (KIT): Provide construction types
ACTION (EPFL): Provide time series and systems
ACTION(Occupancy, JMB, EM): Provide occupancy profiles
ISSUE(Occupancy): Specify the description of the Internal Gains into the documentation table and the md file
ISSUE(Occupancy): Improve the documentation and guidelines
ISSUE(Occupancy): Stick to the CItyGML codelist or INSPIRE codelist? Should we use the INSPIRE registery?

Current research projects taking place at TUM that are closely related to EnergyADE development:

  • Linking sensors and city models
  • Development of the Dynamics part of CityGML 3.0
  • Building a General Indicator Modelling (GIM) and how it can help in understanding building compositions and estimating heat energy demands
  • Demonstration of the Web-Client in visualising 3D City Models and how it can be used for heat energy estimation


TOP 5: Implementation of Energy ADE in Software CitySIM

Jerome Kämpf & Silvia Coccolo (EPFL)

Presentation: Implementation of Energy ADE in CitySim
Presentation: Concrete application case of CitySim

  • Concrete application cases of CitySIM
  • How to connect urban simulation tool CitySIM and CityGML Energy ADE (Methodology)
  • Case study: The EPFL Campus in Lausanne
  • Implementation questions (e.g. time series, glazing ratio)

Time Interval problem

  • The simulation tools generally use TMY, so that the dates of the results are not relevant

Mandatory energy unit

  • The energy unit should be a mandatory attribute (but all other units too)

Optional elements

  • Some of the mandatory elements should be optional, some thoughts should be made on that

List of units to use

  • A list of SI units or other should be put in the Energy ADE (maybe as codelist?), otherwise the tools may have difficulties to recognize it

Glazing ratio

  • The glazing ratio should appear somewhere in the Energy ADE.
  • The discussion was that we can have two surfaceComponents, one transparent and one opaque with each the correct surface

LODs in the energy ADE

  • Some thoughts should be made on how to define different LODs not only for Schedules but also for the buildings, thermal and usage zones
  • We can have a generic description that is mandatory and details that depend on the LoD?

TOP 6: Implementation of Energy ADE in EnEff Campus: RoadMap

Mark-Alexander Brüntjen & Christian Fliegner (RWTH Aachen)

Presentation: To be provided

  • Concrete application case of EnEff Campus Project


TOP 7: Implementation of Energy ADE in SimStadt: An Energy ADE Plugin for CityDoctor

Marcel Bruse (HFT Stuttgart - Geoinformatics)

Presentation: Energy ADE Support for SimStadt

  • Concrete application case of SimStadt
  • How to integrate the Energy ADE into SimStadt (Methodology)


TOP 8: Typological Issues around the ThermalZone Implementation

Prof. Volker Coors (HFT Stuttgart - Geoinformatics)

Presentation: To be provided

  • Relations between AbstractBuilding <> ThermalZone <> ThermalBoundarySurface <> SurfaceComponent
  • Adjacency Concept/Specifications


-> ThermalBoundary needs geometry for validation purposes (optional) (Karl-Heinz)

IMG 20151209 083627455.jpg


TOP 9: Work realised in WG ADE Core + Construction

Energy Certification

  • Keep one attribute for energy certification instead of combining attributes (Joachim)
  • DateOfCertification is to be added as an attribute (Joachim & Maryam)
  • LabelOfEnergyPerformance attribute is to be added (Volker Coors)

Code List <-> Enumeration
Discussion to clarify whether we should resort to Code list or enumeration -> e.g. FloorArea and RefurbishmentClass 6 attributes if they should be enums or codelists (depends on availability) it's been concluded that it's better to stick to CityGML Codelist (Joachim, Karl-Heinz häfele)

Date of Refurbishment
->if it's date it will need a day, month and year of refurbishment which is difficult to get. So it's better to change it to PeriodOfRefurbishment? (Joachim, FIXME!)

Measurement Unit
UnitOfMeasurement should be defined as a codelist comprising different system of unit

Scale
Scale needs to be clarified if it's between 0-1 or 0-100?

->Show an error message when incorrect unit is being used e.g. kw for energy

TODO (KIT): provide construction types

TOP 10: Roadmap toward Energy v1.0

Before Energy ADE 1.0

  • More test cases is to be provided
  • Occupancy Profiles -> Occupancy WG, Jean-Marie and EM?
  • TimeSeries + System: EPFL
  • ThermalZone: HFT


TimeSeries

  • State of time series into CityGML

-> Investigate TimeSeries XML and how to integrate it into CityGML. 2 possibilities:

  1. Extern through a reference in the schema
  2. Intern through time series objects
  • Difficulties to combine relative & absolute time values
  • UOM attribute should be added
  • Irregular time series file?
  • Regular time series file with UnitOfMeasure attribute
TODO (Romain & Mostafa): Romain Nouvel, Mostafa Elfouly & Kanishk Chaturvedi from TUM will check the Schedules and TimeSeries and its conformity to the development of the dynamics part of CityGML 3.0 in order to avoid any overlap (some features seem to be very similar)


LevelOfSimplification
->Question (Kolbe): LoD Schedules -> Why not a LoD for Energy values? ->Different level of aggregation for EndUseType

TODO (EnergySystems): Why not a LoD Energy values?


Topological Issues
->v0.6: ThermalComponent is a physical object (e.g. Window or Door) and not directly related to ThermalZone, ThermalBoundarySurface -> ThermalBoundary

TODO (EnergySystems): Add Geometry in the ThermalBoundarySurface as optional attribute
TODO (EnergySystems): Write specific guidelines on the way to proceed on the topic + Explain Geometry in the ThermalBoundarySurface as optional attribute


Openings

  • Doors in ThermalZone is in the ThermalBoundary
  • IFC and GBXML openings are subtractions of the walls
  • Similar behaviour to CityGML -> Thermal Boundary is a Boundary Surface (which is similar)


ADE Core

  • V0.6: Integration of energy performance certification
  • Protected Buildings/Zones: interesting as it seems not to be integrated into INSPIRE or CityGML 3.0, but after discussion, it was decided to not extra change it and keep links feasible with other initiatives.


Certification

  • Different kinds of certifications: Certification processes (law) & Label
TODO (EnergySystems): Add day of certification (date)


Unit

  • Validation mechanism for constraints (e.g. regarding units): schema tron
  • No particular way to put constraints into the schema, just as text in the guidelines.
TODO (EnergySystems): UnitOfMeasure attribute should be mandatory


PV

  • Question: Suitable surface for PV -> rather an indicator?
  • Question: Requirement for covering ratio for PV modules


TODO (EPFL): provide time series and systems
TODO (Occupancy WG, Jean-Marie and EM?): provide occupancy profiles

TOP 11: Planning of Next steps

OGC TC Meeting in Sydney
-> Energy ADE development work was presented by Prof. Volker Coors on the 02.12.2015 at the OGC TC Meeting in Sydney via online conf.

Further process proposed for the ADE development into the OGC

  • Maintain good visibility by regular attendance at the OGC TC Meetings (in the 3DIM or Energy DWG)
  • Discussion paper
  • Best Practice paper
  • Version 1.0 as standard

-> Open question: What is our final objective: CityGML 3.0? Best practice?

Use Case

  • There is a need for more documentation into the guidelines (e.g. definition of internal gains: solar + devices + occupants?)
  • There is a need for providing a list of use cases from the WS in best practice paper
TODO (All WGs): Complete the guidelines per WGs and check the mandatory or optional attributes
TODO (All WGs): Use existing materials (guidelines, WS use cases, UML) for writing a use case: questions + solving process + illustration/visualisation + follow UML schema

Mailing List

  • Provide different mailing lists: Global & WG-specific ones
TODO (Egbert Casper): Provide list of possible solutions

Dissemination Activities till next workshop

  • Silvia Coccolo et al. is to present the EnergyADE at the 14th International Conference of the International Building Performance Simulation Association, BS 2015, entitled Urban energy simulation based on a new data model paradigm: the CityGML Application Domain Extension Energy. A case study in the EPFL campus of Lausanne.

Next Meeting

TODO (Giorgio): Giorgio will setup a doodle for next WS keeping in mind the public holidays
