2016 W Minutes of the Workshop

Presentations and Minutes

Welcome from the organisers Giorgio Agugiaro (AIT) Presentation: PDF file of the slides Brief welcome and introduction about AIT Some notes about projects and research topics in AIT which are related to the Energy ADE Short introduction round of all participants. The new participants have known of the Energy ADE and the workshop mostly by word of mouth (from AIT, HFT, etc.) or because of European projects which might benefit from the Energy ADE.

Introduction to the Energy ADE, current status Romain Nouvel (HFT Stuttgart) Presentation: PDF file of the slides Short description of how the Energy ADE is structured and works in organisatorial terms. Review of past and future dissemination work Presentation of the first guidelines document for version 0.6 Notes about cooperation with other OGC standards and/or parallel research topics TimeSeriesML 1.0 Dynamizer Module integrated in CityGML 3.0 UtilityNetwork ADE INSPIRE/BEDES data specification and codelists Brief notes about the UtilityNetwork ADE: development started at TU Berlin, now continued at KIT and TU München. In general: great interest due to the complementarity of the UtilityNetwork ADE with the Energy ADE. About Energy ADE and CityGML 3.0: In general, the Energy ADE is currently tailored to CityGML 2.0, as this is the currently available latest CityGML version. It will be adapted and made CityGML 3.0 compliant when the new version of CityGML is released.

Report from the WG Energy Use and Systems Moritz Lauster (RWTH Aachen) Presentation: PDF file of the slides to be uploaded soon Due to the complexity of the module, some changes have been made towards simplification Nevertheless, more use cases and examples are needed. Proposition: move workflows for request of changes in github wiki, make list of examples and tools supporting the ADE. About Units of Measure: Currently two proposals, one from J. Benner (KIT)) (an informal standard) and another one (ISO DIN80000-1). For long term consider a proposal from N. Ghiassi (TU Wien) regarding using ontology as a standard to replace the current ones.

Report from the WG Building physics Romain Nouvel (HFT Stuttgart) Presentation: PDF file of the slides Further discussion needed due to the different modelling approaches in CityGML, gbXML, IFC and EnergyPlus. Further explanations to be given by J. Benner (KIT) in his presentation (see later)

About CityGML Dynamizers Kanishk Chaturvedi and Thomas Kolbe(TU München) Presentation: PDF file of the slides The Dinamizers allow to store dynamic values separately from the original attributes Although conceived as part of CityGML 3.0, it is planned to be released also as ADE also for CityGML 2.0 (late 2016?) Supports patterns, possibility to integrate sensors and observations Please refer to slides for details.

About Energy ADE licensing Thomas Kolbe (TU München) and Volker Coors (HFT) First possibility: approach OGC, i.e. write best practice paper, it later becomes an official position, then it becomes a standard. All the copyrights then belong to the OGC (as CityGML now). In the case of an OCG licence, it remains to be clarifies whether the Energy ADE "belongs" to CityGML or remains "outside". Second possibility: adopt an open source licence like Apache (or GPL, GNU, MIT, Creative Commons). All the original contributors have to be renamed if we use this. T.H. Kolbe's (TU München) suggestion: go with Apache solution and then everything that is done afterwards will always have to mention previous contributors. The MoU SIG3D–OGC could be used to create one for Energy ADE–OGC. P. Cipriano (Sinergis) suggests ISA Core Vocabularies – Open Metadata License. R. Nouvel (HFT): The license should be part of the 0.7 release. An email exchange and a discussion on the issue will take place.

Report from the WG Occupancy Piergiorgio Cipriano (Sinergis) Presentation: PDF file of the slides Presented an exaple of a building that has: post office, company office and public dwellings. Please refer to slides for details

Linking CityGML with EnergyPlus Patrick Holcik and Giorgio Agugiaro(AIT) Presentation: PDF file of the slides Master thesis from TU Wien/AIT: define a bidirectional interface between CityGML and EnergyPlus Issues, constraints and workarounds are discussed

About the thermal boundary concept in BIM Joachim Benner (KIT) Presentation: PDF file of the slides Presentation and discussion about main differences in the BIM modelling of thermal boudaries Examples with IFC Example with gbXML Please refer to slides for details

Different approaches for simulation of energy performance at district level based on CityGML Iñaki Prieto Furundarena (TECNALIA) Presentation: PDF file of the slides to be uploaded soon Brief overview of TECNALIA's projects with CityGML and energy Parallel experiences so far, similar ADE developments. Please refer to slides for details

Ideas for including industrial buildings in the Energy ADE Wolfgang Glatzl (AEE-Intech) Presentation: PDF file of the slides Brief overview of AEE-Intech About relevance of industrial buildings at city scale, some examples First reasonings on how to adapt the Energy ADE Please refer to slides for details

Ideas for a database implementation of the Energy ADE Richard Redweik (virtualcitySystems) Presentation: PDF file of the slides Brief presentation of virtualcitySystems and how they related to the Energy ADE Possible strategies to implement the Energy ADE withing the 3DcityDB Some (partial and tailor-made) implementations already exist. TU Münich is working on a solution to automatically manage _any_ ADE with the 3DcityDB Please refer to slides for details

Consclusions and next steps Romain Nouvel (HFT Stuttgart) Presentation: PDF file of the slides Final work is needed before release of Energy ADE v.0.7 (expected end June/July 2016) Close few remaining open tickets Further update/improve guidelines Choose a license Topics for the following releases: Application/Integration of dinamizers DB implementation Ontology concept for measures Adaptations for industrial buildings More applications and case studies are welcome! Next workshop: very probably in northern Italy around second half of November, details will be given asap by P. Cipriano (Sinergis).
