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 Raise issues within the WGs Meeting / on GitHub. Discuss these issues within the WGs and agree on a solution. The WG coordinators send a detailed update requirement to the Technical Committee per Email. 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 work: Provide General Indicator Model as no GIM exists yet Way to evaluate the indicators and impacts Way 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.
