Activity A1: Definition development
1.1 Identification of the main aspects that we think are important in the definition context (possible examples include system boundaries, different localities, different timeframes, comparing energy carriers, embedded energy, etc.);
1.2 Defining scope: deciding what to include in the PED definition (possible examples include life-cycle energy and emissions and consumption based energy use such as mobility and consumer goods);
1.3 Survey development (in collaboration with other subtasks B-D) for collecting information and developing the state of the art. The main output is a review paper;
1.4 The information will be collected according with the following aspects:
Existing definitions (positive energy buildings, positive energy neighbourhoods, PED, etc.);
Initiatives (national, European, international research projects, other initiatives regarding PEDs);
Case studies (PEDs from approved H2020 SCC or other initiatives) that can be described and used for definition validation;
Literature review about positive energy buildings, positive energy neighbourhoods, PED (scientific papers, books, leaflets, etc.), spatial/temporal scales, essential technologies and components/systems etc.;
Categories of stakeholders usually involved in the PEDs activities;
Regulations and existing barriers for energy sharing in PED;

Activity A2: development of a classification of PED typologies
2.1 Characterizing PED according with several factors to try “to understand their needs and history”: geographic, age, population, culture, types of buildings, construction, use;
2.2 Propose a “Reference” PED or PED Archetype. This can lead to the development of a Virtual PED or a digital twin of PED. This will be based on a solution sets for district level systems, integrate the concepts of energy grids, overall performance, business models, the engagement of stakeholders, mobility, carbon footprint, and social adaptiveness.

Activity B1: Mapping technical solutions
The aim of this activity is to identify the different technical solutions that can be triggered depending on the resources and infrastructures available within a city. Visualizations of the collected data will be development, in the city context visualizations could be supported by GIS. To do so, the following methodology could be approached:
1.1 A comprehensive review of the most common technologies applied in PED (or PED-related, such as smart cities, local energy communities, etc.) at building, district and city level will be conducted. Sources such as demo case studies (Subtask D), PED booklet (JPI Urban Europe), other IEA Annexes, SCC and H2020 projects, energy agencies among others, could be revised to create an inventory of the different technologies applied in a PED or cities approaching PED status. Through this exercise, the best experiences and barriers of the different technologies (functionalities) will be identified.
1.2 From the revision and analysis of the different technologies applied, the technologies can be classified into different topics/areas (heating, cooling, electricity, storage) and scope (building, district, city). In each topic/area the technologies can be compared and evaluated (using KPIs from subtask A) in terms of costs (LCoE,etc), regulatory, environmental, energy efficiency, social acceptance indicators, among others. Consequently, the result of this activity will be a review report/paper (or guideline) critically assessing the existing technologies applied in PEDs in a district/building/city depending on different urban contexts
Activity B2: Smart solutions
The focus of this subtask is to review the most common building/district/city monitoring and control systems. The results from the previous task (B1) and demo cases (Subtask D) will highlight and reveal practical challenges regarding the implementation of smart solutions at different levels, and also future research and development needs in PEDs.
2.1 This activity will conduct a literature review on monitoring technologies, sensors, data collection and control solutions and algorithms feed in from the information obtained in Subtask B1 and Subtask D. Research on data analysis techniques and control strategies techniques (more advanced control systems, forecasting, load shifting, peak saving, demand management, Virtual Power Plants) will be conducted. Other issues such as demand response, flexibility, data management (blockchain) that are useful for managing a PED will be considered. The result will be a comprehensive inventory of the different monitoring and control solutions (depending on the technology) that can be applied at building, district and city level.
2.2 Evaluation of the different smart solutions through Strengths, Weaknesses, Opportunities, and Threats – (SWOT) analysis and KPIs to identify the barriers/enablers of the different smart solutions. Recommendations will be produced for overcoming the recognized barriers and to strengthen then enablers.
Activity B3: Modelling, simulation and optimization tools
The focus of this task is to investigate and identify the tools for modelling a PED (from demand to the energy balance calculation) that can be used for designing and operating a PED.
3.1 Comparison between the different modelling and simulation tools (grey box, black box, commercial software like TRNSYS, IESVE, etc.; data-driven tools like machine learning, Etc.) and classification depending on the data availability, complexity, know how, applicability at the different levels (building, district, city) and scope/objective functions (1 year to long term planning). Review available district level simulation tools and compare with techniques using aggregation of single-building level simulations. Review various optimization algorithms and find suitability with the districts level simulation approaches.
3.2 Calibration, auto-calibration, data cleaning and data analyses techniques will be revised as useful tools for operating a PED. Furthermore, how to use the modelling tools for optimization of the control systems will be evaluated.
3.3 Running simulation and optimization cases for validation and producing data on viability of different PED concepts with different technology combinations under different operating and weather conditions.
