“…A definition that is to be equally achievable in an urban context must therefore take this into account and refrain from a static target value. There are two aspects to consider here: First, this is simply a consequence of the physical facts, as detailed in [15,31,42]. However, there is a second point: in principle, the PED concept should not be opinionated about when and where it can be achievable and how easily.…”

“…A 2021 study on the PED potential of urban typologies in Vienna, Austria, found that only detached housing districts can achieve a positive annual energy balance (for heat and power) of 110%, whereas more dense typologies fail to achieve the criteria with an annual balance ranking between 61% and 97% [42].…”

This paper presents the goals and components of a quantitative energy balance assessment framework to define PEDs flexibly in three important contexts: the context of the district's density and RES potential, the context of a district's location, induced mobility and the context of the dis-trict's future environment and its decarbonized energy demand or supply. It starts by introducing the practical goals of this definition approach: achievable, yet sufficiently ambitious to be inline with Paris 2050 for most urban and rural Austrian district typologies. It goes on to identify the main design parts of the definition: system boundaries, balancing weights and balance targets and argue how they can be linked to the definition goals in detail. In particular we specify three levels of system boundaries and argue their individual necessity: operation, including everyday mobili-ty, including embodied energy and emissions. It argues that all three pillars of PEDs, energy effi-ciency, onsite renewables and energy flexibility can be assessed with the single metric of a prima-ry energy balance when using carefully designed, time-dependent conversion factors. Finally, it is discussed how balance targets can be interpreted as information and requirements from the sur-rounding energy system, which we identify as a "context factor". Three examples of such context factors, each corresponding to the balance target of one of the previously defined system bounda-ries operation, mobility and embodied emissions are presented: Density (as a context of opera-tion), sectoral energy balances and location (as a context for mobility) and an outlook of a person-al emission budgets (as a context for embodied emissions). Finally, the proposed definition framework is applied to seven distinct district typologies in Austria and discussed in terms of its design goals.

“…Analysis and Evaluation of the feasibility of Positive Energy Districts in selected urban typologies in Vienna is presented in article [4] by Hans-Martin Neumann et al, which investigates the potential of selected urban typologies in Vienna to reach the state of Positive Energy Districts (PED) by achieving a positive annual energy balance. Considering relevant urban typologies in different construction periods, the analysis focused on converting the allocated building stocks into PED by employing comprehensive thermal refurbishment and energy efficiency measures, electrification of end-uses and fuel switching, exploitation of local renewable energy potential, and flexible interaction with the regional energy system.…”

This Special Issue of Energies, “Smart Cities and Positive Energy Districts: Urban Perspectives in 2021”, introduces contemporary research on Smart Cities and on Positive Energy Districts. The present Special Issue, namely the fourth Special Issue, Smart Cities and Positive Energy Districts: Urban Perspectives in 2021, has been dedicated to tools, technologies, and system integration for Smart Cities and for Positive Energy Districts. The topic highlights the variety of research within this field, including research on: tools facilitating the evaluation of Sustainable Plus Energy neighborhoods, of enabling-technologies and procedures for Positive Energy Districts, and of multicriteria assessment for the identification of Positive Energy Districts; system integration related to optimized energy and air quality management in the COVID-19 scenario; system integration upgrading existing residential areas to the status of Positive Energy Districts; and renovation models for large scale actions.

“…For this project, we considered 'innovation' as defined in different fields including 'technology and innovation', where innovation can be understood as connected to knowledge spillovers which can improve energy efficiencies [8], also economics and business, where innovation is sometimes an entrepreurial aim related to profit, and also as understood in the social sciences, urbanism and urban studies fields, connected with justice [9], behaviour change post-Covid [10], learnings for social innovation [11] and about measurement and feedback [12] from emerging Positive Energy Districts (PED). However, as one aspect of the +CityxChange project is behaviour change, and about new and future ways to live and create in the city, we concentrate on bottom-up citizen participation and urban change [13]. In general terms, we accept the definition of Katz (2014) that 'Innovation is when new or improved ideas, products, services, technologies, or processes create new market demand or cutting-edge solutions to economic, social and environmental challenges' [14].…”

This paper poses the question: ‘can energy innovation initiatives in Innovation Playgrounds foster a new ‘energy urbanity’ through active citizen participation in the energy transition?’ The concept of ‘Innovation Playgrounds’ and an accompanying Framework are described and linked to implementation evidence of the EU H2020 positive energy research and innovation project +CityxChange, related to emergent active citizen participation in two cities: Limerick, Ireland and Trondheim, Norway. The purpose of the study is to demonstrate that spatially clustered energy innovation initiatives in urban areas involving active citizen participation contribute to a new ‘energy urbanity’ for the energy transition. The research methods are based on a comparative case study approach and close observation of two case sites, with a focus on the ‘Innovation Playground’ area of each city. The article’s three main conclusions are: that a Framework approach to active citizen participation in energy innovation initiatives in urban areas facilitates new models of active citizen and community participation around energy innovation; emergent active citizen participation in energy innovation initiatives in urban areas suggests a new type of engagement that is information-rich, blended, action-led, citizen-focused, and spatial; and that a new paradigm of ‘energy urbanity’ for the energy transition can be proposed.
