“…Indeed, this value is evermore increasing when the positive externalities of renewable production are the driving force of the energy transition, and both energy providers and end-users are requested to take bold steps to align with the EU climate targets and put forward the transformation of the global economy from fossil-based to zero-carbon. Previous to the COVID-19 outbreak and the beginning of the war in Ukraine, it was widely acknowledged that to make prolonging the operation of existing biogas plants profitable, the introduction of a new incentive policy would have been necessary [94]. Our findings indeed confirm this sentiment.…”

Energy production from biogas can play a pivotal role in many European countries, and specifically in Italy, for three main reasons: (i) fossil fuels are scarce, (ii) imports cover large shares of internal demand, and (iii) electricity and heat production from biogas is already a consolidated business. Nonetheless, in Italy, current legislation and incentive policies on electricity generation from biogas are causing a stagnation of the entire sector, which may lead to the shutting down of many in-operation plants in the years 2027–2028 and the consequent loss of 573 MWel over a total of 1400 MWel. This work aims to investigate the potential of revamping biogas power plants in prolonging operation until the end of the plants’ useful life, regardless of the implementation of a new government’s incentive schemes. Based on the time-series analysis of electricity prices in Italy and a case study representative of the vast set of in-operation power plants, our findings show that 700 plants will likely shut down between 2027 and 2028 unless the government adequately rewards electricity produced and fed into the grid via incentive schemes. In detail, our results show that the investment to revamp the plant exhibits a highly negative Net Present Value.

“…As aforementioned, we organized a focus group to validate the hierarchy and the weights by dynamic discussion [61][62][63]. During the brainstorming, experts processed data and contributed to discussion according to their expertise, and a moderator helped discussion among experts and favored the process of reaching consensus on the final set of weights.…”

In recent years, governments, public institutions, and local communities have devoted growing attention to the identification of promising strategies for the preservation and valorization of cultural heritage assets. Decisions on the management of cultural heritage assets based on multiple, often conflicting, criteria and on the stakes of various, and potentially non-consensual actors and stakeholders. In this context, in which the trade-offs between the preservation of assets historical symbolic values and the adaptation to alternative and economically profitable uses play a key role in investment decisions, multi-criteria analyses provide robust theoretical and methodological frameworks to support decision-makers in the design and implementation of adaptive reuse strategies for cultural heritage and public real estate assets. In this paper, we provide a multi-criteria decision aiding approach for ranking valorization strategies of cultural heritage assets aimed at promoting their restoration and conservation, as well as at creating cultural and economic benefits. In detail, we present a novel application of the A’WOT analysis to support the design and implementation of alternative management strategies of abandoned cultural heritage assets. The paper focuses on the potential reuse and management of four historical farmhouses (Cascina Mandria, Cascina Lavanderia, Cascina Gozzani, and Cascina Ortovalle) located in the Agliè Castle estate, one of the Residences of the Royal House of Savoy, currently listed in the UNESCO World Heritage Sites.

“…The AHP is based on the assumption that the decision-maker is always able to express a preference and judge the relative importance of (or preference for) the evaluation parameters [30][31][32]. In other words, it orders a finite number of actions Ai [12,33,34], by evaluating them with respect to a finite number k of attributes aj (j = 1, .…”

The occurrence of natural disasters such as earthquakes represent a worldwide challenge in the conservation of cultural heritage (CH), which suffer from damage due to high vulnerability conditions. Therefore, the protection of CH from seismic hazard is of paramount importance. Damage and vulnerability assessment of CH and artistic assets play a key role in the identification of conservation strategies. Effective strategies require the stabilization of severely damaged buildings and the preventive improvement of constructions structural response to seismic actions. Although the operation of emergency inspections is meant to classify buildings on the basis of buildings residual seismic capacity, investment decisions in restoration and conservation strategies of such vulnerable structures must take into consideration tangible and intangible values of both building structures and artistic goods as well as must combine objectives of verifying structural safety standards and preserving cultural heritage significance. Damage and vulnerability assessment depend on different criteria, which, on the one hand, are related to buildings structural characteristics, materials, and geometrical properties. On the other hand, to the peculiarities and uniqueness of artworks and artistic goods present on structural elements. In this paper, an AHP (absolute) model is proposed to rank multi-criteria prioritization of protection and restoration interventions on a set of 15 churches, which were damaged by earthquakes, occurring in Italy in the last decades. In detail, in order to structure the decision problem, identify key factors, and define the hierarchy, we conducted an extensive literature review and interviewed a pool of experts. Focus groups were organized to develop the set of criteria and sub-criteria and validate the hierarchy by dynamic discussion.Sustainability 2020, 12, 1608 2 of 14 considered composed of independent portions whose limits are identified among either crack patterns or construction/vulnerability defects (e.g., large voids, lack in connections, etc.) [3,4]. Such an approach is particularly effective for churches as macro-elements can also coincide with the architectural portions of the building (apse, façade, dome, etc.), whose brittle behavior has been observed even under earthquakes of moderate magnitude [5,6].Hence, to face the seismic post-emergency phase [7] a comprehensive methodology able to contribute in managing the protection of both artistic assets and structural issues is needed. Damage and vulnerability assessment of CH and artistic assets plays a key role in the identification of effective conservation strategies, which require the stabilization of severely damaged buildings and the preventive improvement of constructions structural response to seismic actions. Investment decisions in restoration and conservation strategies of such vulnerable structures must take into consideration the tangible and intangible values of both building structures and artistic goods. It must also combine objectives o...
