Presentations and Minutes

TOP 1: Organisation of the Energy ADE Development/Revision process

Working Group (WG) organisation

The Energy ADE is structured in separated modules as decided in Stuttgart in May 2014. Each module is developed, documented and updated by a working group with expert participants and two working group coordinators:

  • Energy ADE Core: Romain Nouvel and Mostafa El Fouly
  • Materials: Karl-Heinz Häfele and Joachim Benner
  • Energy systems: Jérôme Kämpf and Moritz Launer
  • Occupancy: Piergiorgio Cipriano and Jean-Marie Bahu
  • Metadata: Volker Krautand Heino Rudolf

In the revision process, these coordinators are in charge of animating the working group with intern online meeting, and centralizing the discussed updates related to their Energy ADE module. Experts can participate parallely to several Working Groups.

Technical Committee (TC)

CityGML standard is formally defined with a XML schema. The same applied to its ADEs. It allows in particular for the automatic generation of class objects within Java, Python etc. using some dedicated plug-ins (e.g. JavaXB), which is essential during the revision process.
In our Energy ADE group, our Technical Committee composed of Olivier Tournaire, Marcel Bruse and Joachim Benner, is in charge of the XML schema development and update. Updates are integrated to the UML model (designed in EnterpriseArchitect) which is converted into a XSD schema (with ShapeChange) compliant with CityGML ADE standard UML. Every revision agreed in the different working groups should be communicated to them, so as to be implemented in the Energy ADE. A central Email address will be created for this purpose.

GitHub, our online platform for the revision process

A GitHub directory "citygml/energy" has been created, hosted by the CSTB since the beginning of the year. This GitHub platform centralizes the issues and discussions of all Energy ADE participants between two ADE releases. Issues are related to specific Energy ADE Modules through its "label". They can be created by everybody. Some specific assignee may be given. Once an issue has been resolved after discussion inside a working group, leading to a solution in the XML Schema, it can be closed.

ACTION (ALL/asap): Every participant of the Energy ADE group should register on this GitHub directory to participate to the revision process (register on GitHub and then ask access to the CityGML/energy directory to Olivier Tournaire from CSTB by providing him your GitHub login).

Wiki page, our support for external communication

It has been decided to use our wiki page hosted by SIG3D only for external communication, using from now only the public page. Our dissemination activities (paper and conference) will be moved from the community portal to the public page. The GitHub platform, more adapted for our revision process, will replace the development part of the "Community Portal".

ACTION (E. Casper/July15):Shift dissemination information from restricted page to the public page. Shift the information related with WG work to GitHub. Work on the wiki interface to make it a bit more fancy. Put onto the wiki: the UML diagrams, the contacts, name of working groups (like the GitHub homepage).

Revision process

  1. Raise issues within the WGs Meeting / on GitHub.
  2. Discuss these issues within the WGs and agree on a solution.
  3. The WG coordinators send a detailed update requirement to the Technical Committee per Email.
  4. The Technical Committee implements the modifications in the XML Schema.
ACTION (TC/July15):Create a Gmail address for contacting TC.

When should be released the next version?

The actual Energy ADE version 0.5 has been released in March 2015, after a 6-month development process. It is compliant with CityGML ADE standard UML modelling and ISO-19xxx. There is presently no documentation about it.
It has been agreed to release a new Energy ADE version before each Semester Meeting, following a 6-month release calendar which leaves time to the developers/users for testing the current version, tackling issues, providing feedbacks. A new version must be then released in October 2015, integrating a documentation of all objects and parameters as well as a guide line.

ACTION (All WGs/Aug15): All Working groups provide modification requests to the TC before the end of the summer, so that they can integrate them in the new release of October
ACTION (All WGs/Aug15): Fill the documentation table and write a Guide lines in a separate documents, integrating examples on how to use the Energy ADE module


TOP 2: Indicators

Mostafa El Fouly. (TU Munich)

Presentation: The INSPIRE Building Model for Energy Applications

Concept: Indicator development and connection between domains. Existing norms for indicators:

  • ISO 37120 for Indicators assessing the performance of the city (KPIs on energy, climate, noise, etc.)
  • ISO 19109 for spatial indicators

Further planned development:

  • Provide General Indicator Model
  • How to evaluate the indicators and impacts
  • How to inform the indicators: Source, accuracy, etc. = metadata


TOP 3: Standard calculation methods and data models

Maryam Zirak (HFT Stuttgart / TU Munich)

Presentation: Proposal of a Material Extension for the EnergyADE

Investigation of the data requirement for different existing standards dealing with Building heating demand calculation: DIN 18599-2, ISO 13790, VDI 6007.

Concept to transform this data requirement into a UML Schema specification: Energy UML Schema >> Object-related UML Schema >> Building UML Schema. Based on this work, Identification of content and structure mismatches between the data requirement of calculation methods and the present version of the CityGML Energy ADE.

ACTION (M.Zirak/Jul15):Report the mismatches as issues on GitHub.


TOP 4: INSPIRE Building - data specification

Piergiorgio Cipriano (Sinergis)

Presentation: Report of the Activities of the Building Physics Group

Inspire directive

  • Latest in 2020, all municipalities have to store and manage geodata, in particular on buildings.
  • In Inspire, 34 data themes are related to energy, but the use cases about energy are limited.
  • Inspire provides technical Guidelines, UML interchange (XMI), GML standards (XSD), etc.

Geosmartcity project (webwww.geosmartcity.org)

  • This project extends the INSPIRE building concept
  • It proposes a template for a table listing attributes and used for documentation

SunShine Project

The European Project SunShine attempts to develop an automatic way to determine building efficiency and (pre)certify buildings based on 3D city model (so-called ecomap). Nevertheless, we must be careful about the validity of the energy labels results due to uncertainty into the input data and the calculation method (missing refurbishment measures for instance).
By certifying all its buildings with a simple generic calculation method based on low data availability, Netherland is a unique case in Europe (webhttp://energielabelatlas.nl). In other countries, less than 10% of the buildings are labelled.

TOP 5: Work in working groups

3 small group have worked in parallel on the class diagram of the version 0.5 of the Energy ADE, discussing with the WG coordinators and identifying some further development requirements.

ACTION (All/Jul.15):Discuss further the points raised during this session, and translate it on Issues/ requirements to add in GitHub.


TOP 6: Urban simulation software CitySIM

Silvia Coccolo (EPFL)

Presentation: Report of the Activities of the Energy Systems Group

Overview of CitySim, an Urban Energy Platform developed in EPFL. Its data model is organised in 4 different modules: Building geometry, Building envelope, Thermal zone, Energy systems.

Silvia and Jerome Kämpf have compared the CitySim and Energy ADE Data models:

  • Difference: Window consider as building geometry, not in CitySIM (ratio of a surface)
  • Similarity: Different usageZones in one building
ACTION (EPFL/Nov.15):1- Export all modules into CityGML format.2- Import CityGML into CitySIM (explore needs to change CitySim model...)


TOP 7: Urban simulation software SimStadt

Romain Nouvel (HFT Stuttgart)

Explanation of data structure of SimStadt and how it is planned to integrate the Energy ADE Schema (XSD file) within it, using JavaXB and some binding functions. For further information, contact Marcel Bruse from the HFT Stuttgart which is realising this technical task.

ACTION (HFT/Nov.15):Implement the Energy ADE v0.5 fully in SimStadt.


ACTION (All/Jun.15):For the persons interesting by the technical implementation of the Energy ADE in software: online meeting before the summer


TOP 8: Metadata development

Volker Kraut (M.O.S.S. Taufkirchen)

Different proposed approaches for Metadata integration

Approach I - Metadata ADE
Pros: ISO19115
Contras: ISO = very detailed and complex, not really readable
-> Metadata related to features and not attributes
Approach II – External references
2nd file with the metadata
Extending the CityModel about capabilities to provide external references stored into the schema
->Metadata for the whole dataset at the attribute level
Approach III – metaDataProperty
GML Tag: metaDataProperty
AbstractMetadataPropertyType for documentation

Decision: Provide a use case based on the approach II and collect requirements.

ACTION (WGs/Nov.15):Provide V.Kraut with specific metadata requirements, corresponding to specific use cases.


TOP 9: Technical implementation of Energy ADE and related Database

Volker Kraut (M.O.S.S. Taufkirchen)

Presentation: Report of the Activities of the Metadata Group

Integration of Energy ADE in Database

To concretly integrate the ADE into their Database (software novaFACTORY), MOSS transforms the ADE into Generic Attributes and store them into an external database. -> Possible problems:

  • Different locations
  • Problem with different version of ADEs but possible way to automatically provide tables.
  • Complex element modelling (nested elements with subtypes) possible solutions

-> Alternative solution from KIT & Claus Nagel (VirtualCitySystem) :Copy the schema into a directory and work on it. VCS deals with the dataset. Extend the table.
Possible solutions are under construction at the TU München: Import/exporter for the timeline to be ready with CityDB (Gia Yao Zihang in TU Munich). Information should be provided in a close future (cf. Mostafa or Prof. Kolbe)

Time Series

We have defined Time Series for the Energy ADE Module “Energy and Systems”. We know that the development team of CityGML 3.0 aims at integrating this concept in the new CityGML release.

ACTION (TUMunich/Summer 15):Check the ongoing process in the CityGML 3.0 WG (Thomas Becker, Klaus Nagel, Thomas Kolbe) regarding Time series


TOP 8: Planning of Next steps
  • Next Meeting
