Positive energy districts (PEDs) are seen as a promising pathway to facilitating energy transition. PEDs are urban areas composed of different buildings and public spaces with local energy production, where the total annual energy balance must be positive. Urban areas consist of a mix of different buildings, such as households and service sector consumers (offices, restaurants, shops, cafes, supermarkets), which have a different annual energy demand and production, as well as a different consumption profile. This paper presents a data modeling approach to estimating the annual energy balance of different types of consumer categories in urban areas and proposes a methodology to extrapolate energy demands from specific building types to the aggregated level of an urban area and vice versa. By dividing an urban area into clusters of different consumer categories, depending on parameters such as surface area, building type and energy interventions, energy demands are estimated. The presented modeling approach is used to model and calculate the energy balance and CO2 emissions in two PED areas of the City of Groningen (The Netherlands) proposed in the Smart City H2020 MAKING CITY project.

The emerging power systems will be proliferated by different distributed generation sources and storage facilities. The adequate modeling of these novel facilities, and power systems in general, is of fundamental importance for the evolution of power systems since the appropriate models are the only tool that can feasibly be used to investigate such diverse and complex multi-domain structures. In other words, the development of digital twins of the distributed generation sources presents a prerequisite for advancements in several domains (technical, financial, social, ecological, etc.). This paper explains several modeling approaches and provides examples of how the models could be used. Full article

This research focused on the development of a Digital Model (DM) of a production line at a medical device company, with the objective of providing decision support to stakeholders based on their energy consumption. This model aims to reduce energy consumption by bringing operational data to process engineers, allowing them to make efficient improvement decisions while in production. In order to achieve this objective, the twin transition of digital integration and energy efficiency was enacted by organisations such as the International Energy Agency (IEA). This two-pronged approach involved working with process owners to understand the decision-making process that they undertook to streamline performance and develop the means to digitalise this data while also working with facilities and maintenance engineers to understand which equipment played the most important roles in the production process from an energy consumption perspective. By bringing the process data and energy data together in a digital model of the process, a decision support system could be developed which would unlock the potential to streamline operations not just from an output perspective, but also from an energy efficient perspective. When examining the process step with data catagorised as energy, operational and maintenance, it was found that only operational data was sufficient to support digital modelling in its current state. Therefore, the installation of a wireless energy metering network would be required to support digital modelling and further digital integration. Full article

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. Full article

The implementation of Nearly Zero-Energy Buildings (NZEB) renovation packages in Europe needs to be accelerated to meet the decarbonisation goals. To achieve this level of performance, building renovation strategies should shift towards industrialised solutions that incorporate a multitude of passive and active components, increasing the complexity and cost of the execution. Moreover, it requires the involvement of different stakeholders of the building supply chain, resulting in additional difficulties in communication and coordination. To address this challenge, this study aims at mapping the renovation process and at addressing the respective bottlenecks. The objective is to identify the type of information that the stakeholders require during the different renovation phases and provide a framework to structure the workflow between all actors. By structuring the information along the renovation process phases, the different stakeholders can identify when the information can be provided and how the different types of information link to each other.

Cost–benefit analysis is a common evaluation method applied to assess whether an energy system is economically feasible as well as the economic viability of energy investment for the energy transition of a pre-existing energy system. This paper focuses on examining the economic costs and benefits obtained through the implementation of renewable energy and smart technology to a pre-existing energy system of two pilot sites—St. Jean and Barcelona. The evaluation process includes all relevant parameters such as investment, operating and maintenance costs, and energy prices needed to assess the economic feasibility of the investment. The results show that investing in energy system development towards a decarbonized future, can provide various benefits such as increased flexibility, and reduced emissions while being economically feasible.

Energy retrofit strategies for buildings represent a major challenge for the achievement of EU decarbonization goals. In 2002, the Energy Performance of Building Directive introduced energy certificates to measure and compare building energy performance, to frame the more suitable renovation actions, and develop financing schemes. However, since its implementation, this instrument remained quite unexploited. In this framework, the EPC RECAST H2020 project aims at developing a new generation of EPCs with a focus on existing residential buildings. Within the project, the paper focuses on the monitoring strategy that has been defined and tested to validate, with real data, what is declared in Energy Performance Certificates. Full article

Energy communities organise collective and citizen-driven energy actions that will help pave the way for a clean energy transition, while moving citizens to the forefront. The energy market is rapidly transforming and so is the role of the consumer. Yesterday’s passive consumers become central actors in today’s energy markets. Today, as prosumers, citizens can benefit from their generation, consumption, and storage capabilities. Moreover, by supporting social engagement and citizen participation, energy communities can help provide flexibility to the electricity system through demand response, storage, and peer-to-peer energy exchange. Based on the collective debate from nine H2020 running projects (Renaissance, COMETS, Sender, eCREW, Lightness, ReDream, HESTIA, UP-STAIRS and NRG2peers), several challenges and key lessons learned can be identified for just social engagement. These challenges and lessons are relevant for the present and future development of EU energy communities. Full article

This paper presents an assessment of the impacts of the different tools implemented within the inteGRIDy project through the analysis of key performance indicators (KPIs) that appropriately reflect the technical and economic domains of the inteGRIDy thematic pillars, comprising demand response and battery storage systems. The evaluation is based on improvements brought about by individual components of the inteGRIDy-enabled smart solution across the Isle of Wight (IOW) pilot site. The analyses and the interpretation of findings for the pilot use case evaluation are presented. The results indicate that the smart solution implementation across the IOW pilot site resulted in achieving the inteGRIDy set objectives. Overall, a 93% reduction in energy consumption, equivalent to 643 kWh was achieved, via the M7 energy storage system and heat pumps developed as part of inteGRIDy solution. Additionally, the grid efficiency and demand flexibility contribution to the distribution network operator (DNO)-triggered DR services, based on a 10% increase/decrease in demand, resulted in stabilizing the grid efficiency.

This article presents preliminary results that assess the effect of electromobility in an archetype Positive Energy District (PED). We present a PED modelling approach that represents renewable energy generation, an energy storage system, the consumption of residential and non-residential buildings, smart lighting services, and the inclusion of electric mobility. We consider renewable energy generation from photovoltaic panels and annual irradiation patterns of the North of Spain to accomplish the electric demands of a synthetic PED. In this general case study, we build up four scenarios where we evaluate at which degree the consumption of EVs would be covered by local Renewable Energy Sources (RES). The simulation results show that the urban areas with great efficiency (in terms of buildings) may support the demand of EVs and even provide a relevant amount of green kms out of PED boundaries.

In this paper, an innovative hybrid modelling technique based on machine learning and building dynamic simulation is presented for the prediction of indoor thermal comfort feedback from occupants in an office building in Le Bourget-du-Lac, Chambéry, France. The office was equipped with Internet of Things (IoT) environmental sensors. A calibrated building energy model was created for the building using optimisation tools. Thermal comfort was collected using a portable device. A machine learning (ML) model was trained using collected feedback, environmental data from IoT devices and synthetic datasets (virtual sensors) extracted from a physics-based model. A calibrated energy model was used in co-simulation with the predictive method to estimate comfort levels for the building. The results show the ability of the method to improve the prediction of occupant feedback when compared to traditional thermal comfort approaches of about 25%, the importance of information extracted from the physics-based model and the possibility of leveraging scenario evaluation capabilities of the dynamic simulation model for control purposes.

The building sector plays an important role in the transition to a climate-neutral society. The international interest in low, zero energy, or zero-emission buildings has grown as a potential means for this transition. A more ambitious step from zero energy buildings is the concept of Positive Energy Buildings (PEB), which are also contributing to the decarbonization of the surrounding built environment, not just minimizing their own carbon footprint. A shared PEB definition is needed in order to enable the design, assessment, and documentation of positive energy buildings. This article describes the ongoing discussions, concentrating on the most essential points. Full article

New energy communities that produce, store, trade and distribute renewable energy guided by innovative digital platforms are currently emerging in many EU member states. Expectations about these communities and their contribution to a ‘just engagement’ of citizens in energy transition are high. However, detailed monitoring of the degree to which these expectations have been realised thus far is often lacking. An innovative way to measure the just engagement of end-users as one of these expectations is based on criteria from environmental justice theories that have developed in recent years. This paper describes the initiation of seven pilot communities in five countries around a specific digital platform, and their assessment with a tailored environmental, justice-based framework. Based on the assessment—part of the ongoing Horizon 2020 project, ‘Lightness’—several challenges to just engagement are identified that are relevant for the project and beyond. Full article

Promoting public participation in urban processes has long been a key issue in discussions about urban governance. However, despite the advantages of more progressive and inclusive city governance, participatory budgeting (PB) often faces challenges to ensure collaboration between different city departments and involved residents. In some cases, residents are unsure about PB models’ transparency, other examples show the way NGOs use the model as a counterforce to central governance and thus local actors lack political and financial support. Moreover, uncertainty and restrictions imposed by the global pandemic in some way also impacted the realization of PB. This research aims to identify stakeholders in the participatory budgeting approach, describing opportunities and challenges of the organizational process and digital technologies as a means of enabling communication and collaboration between actors.

Energy Performance Contracting (EPC) can help the European Union (EU) in accelerating the cost-effective renovation of existing building stock. However, there are many risks and barriers that can inhibit the application of EPC. These barriers include uncertainty about building data, lack of quality assurance regarding the post-renovation energy performance, and process complexity. In order to cross these barriers, this paper presents ModSCO. ModSCO is a web application based on a Reduced Order grey-box Model (ROM) able to systematically quantify the energy savings achieved through Energy Conservation Measures (ECMs) utilising the schema of the International Performance Measurement and Verification Protocol (IPMVP). The benefits of utilising ModSCO in terms of accuracy and time savings are demonstrated with a comparison with a whole building energy model developed with IES-VE. Full article

Energy efficiency in the building sector is a priority of the EU Commission to achieve carbon neutrality by 2050. Renovation of the existing buildings, which are currently responsible for approximately 40% of EU energy consumption and 36% of the greenhouse gas emissions can lead to significant energy savings. This paper presents the EEnvest calculation method for evaluating the financial impacts of technical risks related to energy-efficient renovation of commercial office buildings. The evaluation method aims to increase investors’ confidence and boost investments in the renovation of the existing building. Through a series of Key Performance Indicators (KPI), the technical and financial risks impact is evaluated. The results are strictly connected to building features, climatic conditions, solution sets and mitigation measures specific to the building energy efficiency project. Full article

District heating networks are considered to be a key element for the decarbonization of Europe. The RELaTED project seeks to contribute to the decarbonization of these infrastructures with the demonstration of low temperature district heating networks. One of the demonstration sites consists of more than 50 substations within a subsection of a larger network in the city of Tartu (Estonia), where the temperature was lowered by 10 °C. To ensure the benefits of this new generation district heating network and the fulfillment of comfort requirements, data have been monitored and analyzed at the substation level in an automatic way to facilitate the inspection of every user.
