Italy strives to meet its renewable energy targets for 2030 and 2050, with photovoltaic (PV) technology playing a central role. However, the push for increased solar adoption, spurred by past incentive schemes such as “Conto Energia” and “Superbonus 110%”, raises long-term challenges related to PV waste management. In this study, we present a multi-scale approach to forecast End-of-Life (EoL) PV waste across Italy’s 20 regions, aiming to support national circular economy strategies. Historical installation data (2008–2024) were collected and combined with socio-economic and energy-related indicators to train a Backpropagation Neural Network (BPNN) for regional PV capacity forecasting up to 2050. Each model was optimised and validated using R² and RMSE metrics. The projections indicate that current trends fall short of meeting Italy’s decarbonisation targets. Subsequently, by applying a Weibull reliability function under two distinct scenarios (Early-loss and Regular-loss), we estimated the annual and regional distribution of PV panels reaching their EoL. This analysis provides spatially explicit insights into future PV waste flows, essential for planning regional recycling infrastructures and ensuring sustainable energy transitions. Full article

This paper critically analyzes Italy’s strategies to improve energy efficiency in the residential building sector, focusing on social housing. Using a policy-oriented qualitative research design supported by secondary data analysis, the study examines key instruments such as the Superbonus 110% initiative and the National Recovery and Resilience Plan (PNRR). It explores how these measures align with the European Green Deal and address the dual challenges of ecological transition and social equity. Findings reveal that while the Superbonus and PNRR investments significantly boosted energy retrofitting projects and macroeconomic indicators, access to benefits was uneven, favoring higher-income households. The analysis also highlights systemic barriers, such as bureaucratic complexity and initial cost barriers, that limit participation by vulnerable groups, particularly those living in outdated social housing. The paper concludes that future policies must better integrate social inclusion mechanisms, simplified administrative processes, and effectively target energy poverty to maximize environmental and social outcomes.

This study aims to develop a Secured Fiscal Credits Model to address the challenges of managing Italy’s “Superbonus 110%” tax credit. Using a decentralised governance approach, our research objective is to provide a feasible system to track and control the entire tax credit process, from generation to redemption. The method integrates Artificial Intelligence and blockchain technology within a Decentralised Autonomous Organisation architecture, combined with a Multi-agent System to establish a tokenomics model. The system is structured to prevent accidental errors, such as double spending or overspending, and detect fraudulent behaviours, like false claims of completed work. Our main findings indicate that deploying two Decentralised Autonomous Organisations on the Algorand blockchain significantly enhances trust and security, supporting effective oversight of the Superbonus process and facilitating transparent value exchange among stakeholders. This decentralised governance model introduces substantial automation, reduces biases, and offers a viable solution to strengthen tax credit management. This work proposes an innovative, technology-driven framework that can be generalised to similar fiscal and governance contexts, enhancing transparency and control. Full article

This paper introduces actual considerations for the progressive disuse of residential space in the Alpine territory, considering possible actions. Nowadays, the building complexes built around the 1960s and 1970s (a symbol of mass tourism) are suffering and searching for a new identity. The generation of owners who bought them has aged and the propensities of the new generations for holiday in those places has changed, which means fewer opportunities for leisure, particularly in the winter. Due to the great attention (and seeming opportunities) of current incentive policies toward improving the energy use of the existing stock, the authors investigate the private conveniences of transformations through the refurbishment of these buildings. Starting from a study of the territory and the dynamics of the local population, this research analyzes a possible set of energy works, based on a new (2020) incentive measure, the 110% Superbonus, which consists of a series of facilitation mechanisms, deductions, and reimbursements for building interventions. A large part of the insight is focused on a technical and economic feasibility study of the possible actions, following a process based on the evolution of the legislation. This work is based on a specific case study, located in a small municipality in the Piedmont mountain area, consisting of three apartment blocks of mostly second homes. The methodology adopted lends itself on the one hand, as a guide for preliminary economic energy assessments and, on the other hand, as a policy evaluation tool from the public and private perspectives.

The Superbonus is an Italian tax relief policy aimed at encouraging residential buildings’ energy and seismic efficiency. Only the energy part of the legislation is analyzed here. The tax deductions of the Superbonus exceed the nominal value of the project, making the interventions convenient even for economically disadvantaged citizens and small construction companies. However, the measure has only found wide diffusion in single-family housing, while it proceeds more slowly for multi-family buildings, where procedural complexities greatly amplify the risk of the financial failure of projects. The purpose of the paper is to analyze how urban planning and technical and administrative problems affect the Return on Investment (ROI) when the Superbonus is applied to multi-unit buildings. Therefore, a financial risk analysis is conducted from the perspective of an ordinary Energy Service Company (ESCo), which assumes the burden of carrying out energy efficiency measures. The property considered has all the requirements of an ordinary multi-family building for which the Superbonus is generally used. The works considered are also those carried out most frequently. The study shows that only three out of five energy interventions are financially sustainable. This result is in line with the data provided by the Italian Revenue Agency. Full article

The building sector is crucial in all of the possible net zero scenarios suggested for the European Union. In this area, the Italian situation is exemplary. Italy suffers from an aging and low-performance building stock and needs to increase its annual rate of energy retrofits in order to achieve its 2030 and 2050 targets. Even though since at least 2007, several different incentives schemes intended to stimulate energy-efficiency interventions have been in place, Italy has not been sufficiently able to promote deep retrofits. In 2020, in order to help the economy recover after the lockdowns that were introduced to face the first phase of the COVID-19 pandemic, the existing incentives were increased to up to 110% of investments for interventions that improved the energy class by at least two grades. This so-called “Superbonus” was also extended to the public social housing sector thanks to a credit assignment scheme. Given the results of this provisional phase, a possible policy roadmap for the energy renovation of the residential and educational building stock in Italy is presented in this paper through an analysis of data related to the implementation of current instruments in terms of number of interventions, investment needed, energy savings and evaluation of potential benefits and costs that can derive from an increase in the current deep-renovation rate. Through definition of a long-term renovation strategy, this paper illustrates how market barriers and other issues in instrument design can be tackled and how policymakers can help to develop a sustainable long-term roadmap for energy-efficient buildings. Beyond the residential sector, public buildings, particularly educational buildings, are taken into consideration as well, as they are places of collective use that represent the social values of fairness and sustainability and can therefore have an exemplary role for private initiatives.

In recent decades, the issue of existing buildings’ energy retrofit has played a central role in the context of international and national territorial development policies, mainly due to the obsolescence state that characterizes the housing stock. Since the current need for energy renovation collides with the widespread low spending capacity of the owners, in recent years numerous fiscal incentives have been envisaged, aimed at promoting building initiatives for the improvement of energy performance indices. With reference to the Italian fiscal measure so-called Superbonus, introduced by the “Relaunch” Law Decree No. 34/2020, in the present research, a model for evaluating the economic benefits, in terms of the convenience of the operators involved, generated by energy requalification interventions, has been proposed. The analysis has been developed with regards to the Italian territory and to the prevailing building typology, by considering 110 provincial capitals and the main urban areas into which each city is divided (central, semi-central, and peripheral). Specifically, for each urban area of the Italian capitals considered, the market value differential between the after energy and before energy intervention situations has been firstly determined. Furthermore, assuming an ordinary profit margin of a generic investor interested in this type of investment, the break-even incentive, i.e., the percentage threshold able to ensure the condition of minimum convenience for an investor, has been estimated for each urban area.

The age of the Italian building heritage has prompted the Government to implement regulatory measures aimed at mitigating the seismic risk, encouraging anti-seismic interventions on residential buildings through specific tax benefits. This work intends to analyze the economic convenience associated with these building transformations from an appraisal perspective, proposing an analysis methodology aimed at evaluating the increase in market value of the transformed properties, and at identifying the most convenient among the various feasible interventions. The application to a case study allows highlighting the net economic benefits in the owners’ portfolios able to compensate the logistical inconveniences associated with this type of intervention, soliciting a greater awareness of seismic risk, and favoring private initiative at a widespread level.
