Annex 83 Workshop  | Palermo | 12-14 April 2023

Annex 83 organised its 6th working meeting, this time in Palermo. This is the second face-to-face along with online (hybrid) event arranged for the working meeting. Happy to have experts, PED enthusiast and various PED projects under one platform. All participants were excited to discuss and share the ongoing development, future plans with the Positive Energy Districts in Annex83.

During parallel sessions held at the working meeting:
  • Subtask B had the opportunity to discuss how data for modelling PEDs or districts, or energy communities can be organized and used for various modelling software.
  • Subtask C members have been involved in an interactive workshop managed by Eurac and Politecnico di Torino to discuss and identify the expected multiple benefits related to PED implementation. Then, shortlisted benefits have been individually ranked by participants by using the best/worst scaling method. Also, the framework analyses for the three sustainability pillars were presented, with a particular focus on the social aspects.
  • It was a great opportunity to discuss synergies and potential collaborations, also among subtasks (B&C, A&B). 
  • STB and STC will collaborate for the identification and quantitative formulation of indicators.

Subtask B

The Annex 83 Summer school on “Positive Energy Districts: Towards a holistic approach to modeling and performance assessment” was held in Canada in the first week of July. The school tackled issues such as plus energy design, urban energy modeling, energy systems modeling, energy flexbility, environmental analyses, data-driven modelling, business models and experiences from key projects such as Syn.ikia, MAKING-CITY, or ATELIER were presented. More than 30 students from different countries around the world participated and work on energy modelling of different case studies (MONTREAL: DOMPARK, AMSTERDAM: REPUBLICA, BARCELONA: Santa Coloma de Gramenet). The students will continue working on the case studies assessing different topics (energy flexibility, building renovation, renewable energy integration, etc.) that are relevant for realising PEDs, and publishing different articles about it.

Smart and Sustainable Planning for Cities and Regions Conference

Between 19th and 22nd of July we attended the SSPCR conference in Bolzano. First day of the conference was dedicated to PEDs where we held a session on 'Sharing the experiences on Positive Energy Districts: Lessons learned from Annex 83'. At our workshop there were four discussion groups, each for each subtask. The participants were asked to discuss on these questions:


  • What are the essential PED DNAs? Can we create generic PED archetypes based on them?
  • What are the categories of quality of life indicators relevant for PED development?
  • How would you use a database tool to learn about PED development process (ie. using static information for dynamic decision-making)?


  • Which future technologies do you think/expect will be included in PEDs and cities?
  • What can be the challenges/barriers of PEDs in the future (regarding control, smart solutions, modelling, technolgoies...)?
  • What is your expectation for modeling and how models can help to shape cities/PEDs?


  • What is the impact of stakeholders in the PED desing/decision process, what are their "interests" and how are stakeholders likely to be involved in the overall process?
  • What costs do you expect to bear and what revenues do you expect to realize from the PED implementation and, in relation to these, which aspects should be included in the organizational/business models?
  • What would you prioritize in terms of energetic aspects or efficiency and social implications of living in a PED? Which aspects are more relevant for you?


  • STD-CA-JPI are developing a database of PEDs and PED-Labs and it is expected to be partially open for the different stakeholders: What would be your main interest on consulting the Database?
  • In the first phase of the project 25 guidelines were analysed and further guidelines are going to be analyzed. From your point of view, what information would be the most interesting to see (e.g. Inception, Design, Monitoring, implementation, technical aspects, PEDs Phase, ..)?
  • In your opinion who can have benefits from the PEDs studies and Annex 83 results? Which stakeholders are interested?

Subtask A and B held a session on "Planning and Implementing Positive Energy Districts from Concept to Practice: Mapping of Characteristics, Technologies, Stakeholders, Methods and Processes" and subtask C on "Towards a sustainability assessment of Positive Energy Districts: methodologies, case studies and applications".

We will share the outcomes of the workshop in the near future. 

Upcoming event

Annex 83 working meeting is scheduled for 14-16 September 2022 in Finland (if circumstances allow).

Summer School for PhD 

The first summer school for PhD students of IEA EBC Annex 83 just concluded in Montreal, Concordia University.

Newsletter [December 2021]

Subtask B
Is planning many activities for the upcoming year. First of all, a workshop on case studies will be held in March 2022 (jointly with other subtasks), in which the concept of different case studies, data availability and, (possibly) the energy system model and assumptions will be presented. The outcome of the workshop will be to develop a series of PED use cases that are representative enough for the Annex 83 and that will be modelled in the next months by Subtask B. In the 23rd of June an Annex 83 energy systems data and modelling course will be organised by Concordia University in Montreal, using the results of the workshops and subtask B colleagues and studies. Furthermore, a session for the Smart and Sustainable Planning for Cities and Regions – SSPCR 2022 will be organised on the topic “Energy systems, Modeling and Control for Positive Energy Districts”.

Subtask C
is organizing a special session at the Smart and Sustainable Planning for cities and regions (SSPCR) conference in Bozen next July. The title of the session is "Towards a sustainability assessment of Positive Energy Districts: methodologies, case studies and applications". The topics of the session will include - among the others - Positive Energy Districts modelling and simulation aimed at decarbonization, analyses of good practices to achieve sustainability objectives, sustainability assessment frameworks and key performance indicators, sustainability assessment methodologies with a focus on environmental, economic and social impacts.

Subtask D
After completing the scoping phase of Subtask D1, the framework for data collection is being carried out in collaboration with the COST Action (CA19126 – Positive Energy Districts European Network) and JPI Urban Europe. The original template elaborated out of the specific requests of Subtasks A, B and C, has been merged with the COST Action and JPI Urban Europe data collection plans, and the resulting on-line form will be ready by mid-January of next year. The final version of this form will be presented to the Subtask A, B and C leaders to get their final approval and start the data collection phase.

New section on website
We created a new section on our website dedicated to multimedia It is a place where we want to upload input from meetings and other events organised by subtasks. Therefore, we encourage you to share with us interesting content that may be of interest to other participants.

And as always, for further updates we invite you to regularly visit this page.

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,
