Upcoming workshop of PED initiatives hosted by EERA JPSC

Annex 83 is participating in the Workshop of PED initiatives on preliminary results: Towards a European PED definition. The workshop will be held on the 17th of September 2021, 10:00 – 12:00 CEST and is hosted by EERA JPSC. The workshop aims to discuss preliminary results of the alignment core group on PED definition and integrated approach and also discuss further PED definition process.

Update from Subtask B

In the bi-monthly meetings of Subtask B, members make presentations on urban data and energy modelling of PED to increase the collaboration between partners. In the last meeting on the 24th of June 2021, Subtask B had presentations on district heating networks from the University of Valladolid with a large monitoring data set available and from the University of Catania on agent based modelling.

In the next meeting on the 25th of August 14:00-16:00 CEST, the two following presentations are planned:

  • Xingxing Zhang “Digital Twin for Accelerating Sustainability in Positive Energy District: A Review of Simulation Tools and Applications”,
  • Ursula Eicker “Concepts for an automated workflow of district scale building and energy system modeling”.

  • the established Annex website, Twitter and LinkedIn accounts
  • the PED invited session to be held in the International Conference on Sustainability in Energy and Buildings
  • the published articles by Annex 83
  • the Annex 2nd Working Meeting held in April 2021

The Annex progress was very well received by the ExCo supervising member.


Announcement of a workshop organised by Concordia University

Library workshop for Urban Platform: Use of data libraries and catalogue concepts for energy systems, occupancy, green roofs and other urban domains


Time: Monday, July 12, 2021, 9 to 11 AM EST

Workshop presenter: Kai Brassel, Hamburg/Germany

Participation link:


The goal of the workshop is to understand data modelling for urban scale applications and to implement such data models in catalogues. These catalogues could be a basis to share information with country specific performance and/or cost data.


Background reading: Kai Brassel  shared a tutorial that he wrote especially for domain experts: Kai (Guest): How to Create Parameter Catalogs for Simulations (posted in CERC NextGenCities Platform / Parameter Catalogs at 20. April 2021 19:30:35 MESZ).

NOTE: if you don’t have access to Concordia Teams, you can find it here as well:


The document gives some „historic“ context - IT and project wise - in chapter one. Second chapter, then, explains step-by-step how to practically start with data-modelling. Again, not all technicalities may be important for the first read, but at least you should digest, and ideally exercise, the chapter „How to Implement Parameter Catalogs with Eclipse“. In there you find further references on data modelling, and especially you should carefully look at the 18 slides about Object Oriented Modelling and Domain Models by Steve Easterbrook (University of Toronto,

Paper submissions for SEB21 Conference
The deadline for papers submission for the PED session of the SEB21 conference has been extended to the 16th of June! This will give us the chance to increase the Annex participation to the conference. However, do not wait until the last day and try to submit your paper according to the original schedule by the 4th of June.

Webinar on LowCarbon, Positive Energy Resilient Communities
There will be a webinar that will be held on October 12, 2021, 11:00 am 2:30 pm EST. This Webinar is related to the project: CAE Roadmap to Resilient Ultra-Low Energy Built Environment with Deep Integration of Renewables in 2050. More information at

2nd Working Meeting [April 2021]

THE EBC Annex 83 held its second Working Meeting on 21st and 22nd of April 2021. Around 100 participants from 23 countries took part in several sessions held online. The subtask leaders shared the current status of their groups work and presented the next planned steps.

Since last Working Meeting, Subtask A worked on first version of ST-A data collection table. Subtask B organised two workshops, developed a first version of the PED cases technology review and created a repository for open-source database for PEDs. Subtask C presented the current status of the creation of the repository and informed about upcoming workshop on PED KPIs which will be held on 19-22 of October. Subtask D shared an update on demo case template creation and ongoing collection of PED guidelines. Additionally, all subtasks are working on publications. 

The next Working Meeting is planned for 23-24 of September 2021.

Annex 83 PhD students network
In order to create connection between PhD students who are participating in the Annex for collaboration in their research and publications, a survey has been initiated. PhD students are kindly asked to fill out their data from this Teams link indicating their name, email address, affiliation, country, tentative thesis title or main research filed, brief description about the PhD research, and in which subtask they are participating. Please note that there will be a special session (PhD Talk) on the 2nd day of the next Annex Working Meeting (22 April 2021), where some students can present the progress of their PhD research and can discuss with other students.
