“…The model, by means of clustering techniques, helps obtain the tilt and azimuth of each surface on any rooftop, with a level of detail 2 (LoD2) in 3D models according to the CityGML standard [37]. A filter is also applied to consider a minimum rooftop area and width and to remove the small rooftop spaces [38]. For the centroid of each of the remaining surfaces, the global irradiance is applied for all combinations of azimuth and tilt using the Liu and Jordan isotropic irradiance model [39], which is widely employed in urban areas due to its accuracy and simplicity [40,41].…”

Solar photovoltaic self-consumption is an attractive approach to increase autarky and reduce emissions in the building sector. However, a successful deployment in urban rooftops requires both accurate and low-computational-cost methods to estimate the self-consumption potential and economic feasibility, which is especially scarce in the literature on net billing schemes. In the first part of this study, a bottom-up GIS-based techno-economic model has helped compare the self-consumption potential with net metering and net billing in a Mediterranean municipality of Spain, with 3734 buildings in total. The capacity was optimized according to load profiles obtained from aggregated real measurements. Multiple load profile scenarios were assessed, revealing that the potential self-sufficiency of the municipality ranges between 21.9% and 42.5%. In the second part of the study, simplified regression-based models were developed to estimate the self-sufficiency, self-consumption, economic payback and internal rate of return at a building scale, providing nRMSE values of 3.9%, 3.1%, 10.0% and 1.5%, respectively. One of the predictors with a high correlation in the regressions is a novel coefficient that measures the alignment between the load and the hours with higher irradiance. The developed correlations can be employed for any other economic or demand scenario.

“…In the same line, the directive for boosting renewable energy sources [15] says that moving towards such energy sources the GHG emissions will be substantially reduced while the human health and air quality will be improved. Different studies regarding improvement of energy communities have already analysed the agreement of their results with the "Fit for 55" package [16] or, at least mentioned their awareness and importance of such piece of legislation [17,18]. From the depicted literature review, one can verify the attention that the scientific community has given to enhancing energy communities' performance.…”

Several literature works have highlighted that the expansion of electrification across all sectors is a crucial factor in promoting the transition of energy systems towards carbon neutrality by mid-century. However, polygeneration systems through the appropriate integration of different renewable energy sources are expected to play an important role in such transition by effectively reducing the total primary energy demand, as explored in the present work for an energy community (EC) case study. Therefore, this paper presents the optimal synthesis, design, and operation of an EC system working under three different scenarios and evaluates the trade-offs between the total annual costs and greenhouse gas (GHG) emissions (evaluated as CO2 equivalent emissions). The EC is a District Heating and Cooling Network (DHCN) composed of nine third sector buildings in the northeast of Italy. The DHCN superstructure includes several possible energy supply components for each EC member, a central unit, and heat and/or cooling connections between buildings. Moreover, peer-to-peer electricity sharing is allowed among EC members, through a local electricity grid, before buying/selling electricity from/to the main grid. The superstructure was optimised through a mixed integer linear programming (MILP) model considering a multi-objective optimisation for the total annual cost (for owning, operating, and maintaining the entire system) and the total annual CO2eq emissions as the objective functions. The three scenarios through which the EC system is optimized and evaluated consider the type of consumed gas (natural gas or biomethane) and the electricity consumption configuration (on-grid or off-grid). Results have shown that the cost (per ton of CO2eq) to reduce emissions is too high if the European Union's carbon market is considered. This was especially critic for the natural gas scenario, where the cost per ton of CO2eq (between two optimal solutions) was about four times higher than its cost on carbon market.

“…Other studies have investigated the link between RECs and domestic hot water (DH) demand. The work by Masip et al [22] was centered upon a community of 150 residential buildings connected to a PV system and heat pumps. Again, it was shown that consistent emissions savings (up to 85% for thermal demand and 23% related to electricity) can be achieved.…”

Renewable energy communities (RECs) have been gaining momentum around the world, as a way to promote sustainable development and combat climate change. These communities are typically composed of individuals, businesses, and organizations that come together to invest in and promote the use of renewable energy sources, such as solar, wind, and hydraulic power. This article focuses on the benefits that renewable energy communities bring to a territory through the diffusion of renewable energy systems, tackling different issues like local depopulation, increasing energy prices, and a lack of jobs, while reducing greenhouse gas emissions and improving air quality. The novelty of this article lies in the results from the first-of-its-kind national call within the Next Appennino program, part of the National Complementary plan, aimed at the formation and proliferation of RECs in the area severed by the 2009 and 2016 earthquakes in Italy, as a way to add social, environmental, and sustainable value to the reconstruction of this territory. The data refer to the municipality of Castelraimondo and Unione Montana dei Monti Azzurri (a consortium of mountain municipalities), both located in the Marche region. Analysis of the consumer and prosumer energy needs, as well as the quantification of the exploitable production from the new renewable generators installed, showed that a total of 6.134 GWh/year can be shared by the community.
