Positive Energy Districts (PEDs) are a promising approach to urban energy transformation, aiming to optimize local energy systems and deliver environmental, social and economic benefits. However, their effectiveness and justification for investment rely on understanding the additional value they provide (additionality) in comparison to current policies and planning methods. The additionality perspective is not used yet in current evaluations of PED demonstrations and pilots. Therefore, this paper introduces the concept of additionality in the evaluation of PEDs, focusing on the additional benefits they bring and the circumstances under which they are most effective. We discuss the additionality of PEDs in addressing the challenges of climate neutrality and energy system transformation in three European cities that are funded by the European Commission’s H2020 Programme. It should be noted that given the ongoing status of these projects, the assessment is mainly based on preliminary results, as monitoring is still ongoing and quantitative results are not yet available. The paper discusses the drivers and barriers specific to PEDs, and highlights the challenges posed by technical complexities, financing aspects and social and legal restrictions. Conclusions are drawn regarding the concept of additionality and its implications for the wider development of PEDs as a response to the challenges of climate neutrality and energy system transformation in cities. We conclude that the additionality perspective provides valuable insights into the impact and potential of PEDs for societal goals and recommend this approach for use in the final evaluation of R&I projects involving PEDs using actual monitored data on PEDs.

To achieve the “well below 2 degrees” targets, a new ecosystem needs to be defined where citizens become more active, co-managing with relevant stakeholders, the government, and third parties. This means moving from the traditional concept of citizens-as-consumers towards energy citizenship. Positive Energy Districts (PEDs) will be the test-bed area where this transformation will take place through social, technological, and governance innovation. This paper focuses on benefits and barriers towards energy citizenships and gathers a diverse set of experiences for the definition of PEDs and Local Energy Markets from the Horizon2020 Smart Cities and Communities projects: Making City, Pocityf, and Atelier.

Positive Energy Districts (PEDs) have the potential of accelerating the decarbonization of urban areas and promoting scalability between cities. The development and real-world implementation of such innovative concepts can be enhanced through urban energy modelling. However, assessing PEDs can be challenging, and information on this topic is scarce and fragmented. The main contribution of this paper is collecting and analyzing challenges and limitations of energy modelling software for assessing PEDs through five case studies in Italy, Spain, The Netherlands, Denmark and Canada. Case studies are assessed first from a modelling approach, then the main identified challenges and limitations of modelling tools for PEDs are discussed, and finally, various ongoing trends and research needs in this field are suggested.

BackgroundThis research study applied the 'Integrated Energy Landscape Approach and the Ecosystem Services Framework' to formulate a pre-proposal for a Positive Energy District in the Hoogkerk Zuid neighborhood in Groningen, the Netherlands.ResultsThe proposed energy saving and energy generation interventions are sufficient to cover the energy usage of the district, while an energy surplus is generated. The pre-proposal has been developed within a participatory process, organized by the authors in close collaboration with key local stakeholders. The identification of local ecosystem services served as a crucial starting point for this study, while it also served for the basis for analysing the subsequent trade-offs and synergies derived from the proposed energy transition interventions. Then, a sustainable business case model was developed based on this Positive Energy District pre-proposal. The main outcome of the model lies in the value creation through cost savings from not using traditional energy sources and selling electricity to the grid. In addition, the economic value of the preserved ecosystem services and of the synergies generated by the pre-proposal are also included in the model.ConclusionsBeyond the local case, the results lay the groundwork for more systematic studies on merging the methodologies of Positive Energy District development, the Ecosystem Framework and the Integrated Energy Landscape approach. Finally, by adding the benefits of ecosystem services and synergies as a significant contributor in the financial analysis and decision-making process, this study opens the door to a new approach to the evaluation of sustainable projects.

This research study applied the Integrated Energy Landscape Approach and the Ecosystem Services Framework in order to formulate a pre-proposal for a Positive Energy District in the Hoogkerk Zuid neighborhood in Groningen, the Netherlands. The proposed interventions are sufficient to cover the energy usage of the district, while an energy surplus is generated. The pre-proposal has been developed within a participatory process, organized by the authors in close collaboration with key local stakeholders. The identification of the local ecosystem services served as a crucial starting point for this study, while it also provided the transparent information base for analyzing the subsequent trade-offs and synergies derived by the proposed energy transition interventions. Then, a sustainable business case model has been developed based on this Positive Energy District pre-proposal. The main outcome of the model lies within the value creation through cost savings from foregoing traditional energy sources and sale of electricity to the grid, but also through including the economic value of ecosystem services and synergies when integrating the Renewable Energy Technologies. Beyond the local case, the findings lay the groundwork for more systematic studies on merging the methodologies of Positive Energy District development, the Ecosystem Framework and the Integrated Energy Landscape approach. Finally, by adding the benefits of ecosystem services and synergies as a significant contributor in the financial analysis and decision making process, this study opens the door for a new approach of valuing sustainable projects.

It is assumed by the projects demonstrating Positive Energy District (PED) concepts in cities across Europe that citizens should want and need to be involved in the development of new energy concepts, such as PEDs for these concepts to be deployed successfully. Six different PED research and innovation projects are investigating the types and expectations of citizen engagement. They evaluate the impact of energy citizenship on the success of PED deployment across Europe.

Positive Energy Districts (PEDs) are potential high-impact climate change mitigation actions towards low carbon or even climate neutral cities. This implies that the energy performance and greenhouse gas emissions of PEDs need to be assessed. To this end, an accounting methodology, metrics, supporting (accounting) tools, and reporting are necessary that capture the full energy and climate impact of PEDs. The European Commission's Building Energy Specification Table (BEST) provides a methodological approach for calculating the energy balance of PEDs. The BEST is a formal requirement of the European Commission's proposal process, with respect to the Horizon 2020 funding program. An improved methodology for calculating the annual energy balance of a of PED, based on the international standard ISO52000, was developed by the Making City project in 2020. In this paper, we evaluate and compare accounting methods for assessing the energy performance of PEDs and conclude on their use and shortcomings. The hypothesis to be explored is that current accounting practices are based on accounting at a building level and alternative methodologies are needed to capture the full impacts at a district level. To this end, we apply the current approaches on the ATELIER project's PED pilot in Buiksloterham, Amsterdam, which will serve as a case study to illustrate the differences in outcomes and in the use of the results in evaluation and policy making. Consequently, we reflect and recommend on improved approaches and methodologies.

This report relates to the Horizon 2020 project entitled ‘Making City’. The report was conducted by the Hanze University of Applied Sciences to the benefit of theMunicipality of Groningen and other consortium partners in the Making City project and addresses the legal impediments that may arise when creating and achieving a Positive Energy District (PED). In doing so, it specifically addresses the situation in the city of Groningen and the legal framework of the Netherlands.This report highlights legal developments of (upcoming) EU and mostly Dutch legislation related to a PED, such as the Collective Heat and Supply Act (Warmtewet) and the Environmental Act. Moreover, smart contracts used in the Block chain technology is discussed and a chapter on Intellectual Property legislation is included which becomes relevant when using new innovations and technologies. Furthermore, it identifies certain legal barriers that emerged in the establishment of the Groningen PED.

To help the cities realise their positive energy districts, the Atelier project includes a capacity building programme, in which professionals in the partner cities can learn from each other and experts how to make their ambitions come true. Amsterdam University of Applied Sciences is one of the partners to design the training, learning, and coaching activities. Here are five hard questions to give an impression on what kind of knowledge and expertise is needed.

The paper describes the first implementation of the Unified Citizen Engagement Approach (UCEA), a newly developed design-oriented framework for citizen engagement in the energy transition. The preliminary testing and evaluation of several of its pathways in Groningen, the Netherlands, show that the role of design in the energy transition is not limited to the adoption of (co)design tools and methods. Instead, design should be integrated in the process in a more holistic way and on multiple levels, taking into account broader issues than energy, the maturity of local initiatives, and effective communication with stakeholders.
