“…Groningen followed a similar approach at this stage, and later on will need to implement monitoring solutions and control strategies to measure the achievement of the energy surplus. Note that for PED studies in general, one has to aggregate and disaggregate energy balance calculations, see [13].…”

The calculation of the energy balance at the district level is complex since it includes a diverse set of loads, technologies, energy carriers, trading interactions between users and external grids (power, district heating/cooling, gas, etc.) and assumptions such as the identification of Primary Energy Factors (PEFs) in different contexts. This research validates the H2020 MAKING-CITY methodology for calculating the energy balance of Positive Energy Districts (PEDs) in two case studies: the cities of Groningen and Torrelago. For each case, the steps defined in the methodology are followed, dealing with assumptions on non-renewable Primary Energy Factors and critical elements regarding the district boundary. This research shows the applicability of the developed calculation methodology for cities in the design phase as well in the implementation phase of PEDs.

“…In 2018, the European Strategic Energy Technology (SET) Plan Action 3.2 Smart Cities and Communities Implementation defined the concept of positive energy district (PED) [47]. PECs and PEDs are regarded as effective solutions to facilitate energy transition and reduce CO 2 emissions in cities [48,49]. The goal of PECs and PEDs is to realize a balance between energy efficiency, energy flexibility, and energy production in order to achieve climate neutrality and energy surpluses [50].…”

Achieving climate neutrality requires reducing energy consumption and CO2 emissions in the building sector, which has prompted increasing attention towards nearly zero energy, zero energy, and positive energy communities of buildings; there is a need to determine how individual buildings up to communities of buildings can become more energy efficient. This study addresses the scientific problem of optimizing energy efficiency strategies in building areas and identifies gaps in existing theories related to passive design strategies, active energy systems, and renewable energy integration. This study delineates boundaries at the building and community scales to examine the challenges of attaining energy efficiency goals and to emphasize the intricate processes of selecting, integrating, and optimizing energy systems in buildings. The four boundaries describe: (B1) energy flows through the building envelope; (B2) energy flows through heating, ventilation, air conditioning and energy systems; (B3) energy flows through individual buildings; (B4) energy flows through a community of buildings. Current theories often treat these elements in isolation, and significant gaps exist in interdisciplinary integration, scalable frameworks, and the consideration of behavioral and socioeconomic factors. Achieving nearly zero energy, zero energy, and positive energy communities requires seamless integration of renewable energy sources, energy storage systems, and energy management systems. The proposed boundaries B1–B4 can help not only in analyzing the various challenges for achieving high energy efficiency in building communities but also in defining and evaluating these communities and establishing fair methods for energy distribution within them. The results demonstrate that these boundaries provide a comprehensive framework for energy-efficient designs, constructions, and operational practices across multiple buildings, ensuring equitable energy distribution and optimized performance. In addition, the definition of boundaries as B1-B4 contributes to providing an interface for energy-efficient designs, constructions and operational practices across multiple buildings.

“…PEDs make optimal use of elements such as advanced materials, local RES and storage (Ala-Juusela et al, 2016), smart grids (Castillo--Calzadilla et al, 2022, demand-response, energy management (electricity, heating, and cooling), user interaction or involvement by the means of ICTs tools. When analysing PEDs, the self-sufficiency (Ala--Juusela et al, 2016;Cauševi et al, 2021) and the neutrality of the buildings implementing a local energy share scheme is crucial (Fichera et al, 2021).…”
