The main aim of the study was to reduce carbon emissions in the atmosphere using a novel Andropogon narudus (AN) biofuel using higher air temperatures and reducing the consumption of conventional fossil fuel (diesel). The use of a heat exchange chamber within the air intake manifold is a popular method to reduce hydrocarbon (HC) and carbon monoxide (CO) emissions during cold starts. A premixed charged compression ignition engine in the dual-fuel mode was used in this study with raw diesel, raw AN oil, AN70+D30, AN80+D20, AN80+D20 (35 °C), AN80+D20 (40 °C), and AN80+D20 (45 °C). A chamber was designed and analyzed to measure the exit temperature and density change and to determine the reduction in volumetric efficiency of the engine, using Ansys Fluent software. A sustainability assessment study was performed to understand the feasibility of the fuel and the design using the Pugh Matrix. The fuel AN80+D20 with an air temperature of 45 °C was found to be superior to all other fuels in terms of brake thermal efficiency, reaching at 32.1%. D100 used the least amount of energy, whereas AN80+D20 used the most. Engine HC emission was at the lowest (45.01 ppm) for AN80+D20 fuel at 45 °C air input and reached the highest (50 ppm) for AN100 fuel. With an air temperature of 45 °C, CO emission was at its lowest for AN80+D20 gasoline (0.018%) and was at its highest for AN100 (0.072%). Nitrogen oxide emissions were the highest for AN80+D20 fuel with an air temperature of 45 °C, with an air concentration of 1254 ppm, whereas they were the lowest for AN100 (900 ppm). CO 2 values were reduced, with D100 showing the lowest levels and AN100 showing the highest. The smoke emission was minimum for AN80+D20 fuel at 45 °C, with a smoke number of 15 compared to 33 for D100 fuel. As per the Pugh Matrix assessment, AN80+D20 with 35 °C air temperature had higher scores compared to all of the other fuel mixtures.

“…The foresting of strategies and actions to make urban environments and buildings more sustainable, both in the private and public sectors, is a cornerstone of the European Union's long-term vision for a climate-neutral economy. Economic and financial feasibility analysis of energy efficiency measures on the building, district and city scale have been widely applied to the evaluation of energy retrofit projects for near-zero energy buildings (NZEB) and various types of existing buildings [8][9][10][11], as well as for the definition of best urban energy scenarios [12,13], also in the presence of public incentives and supporting public decisions with multi-criteria models [14,15].…”

Energy communities using renewable energy sources directly contributes to reduction of climate change gas emissions and energy consumption in the European Union. In addition, energy communities enable citizens to transform from (passive) consumers to prosumers (active consumers and producers) and to play a proactive role in the deployment of energy transition in urban areas. As the transposition of European rules about energy communities into the national laws of EU Member States is very articulated and differentiated, this study proposes a framework to analyze and compare regulatory and financial instruments. This framework is applied to the analysis of the cases of Italy and Spain as representative of European states in which collective actions in the energy sector are not very common, with the aim of highlighting the main critical issues affecting the effectiveness of energy transition strategies and assessing the economic feasibility of energy communities. Based on analysis of regulations and procedures, including at the local level, it appears that municipalities play an important role as promoters of initiatives among citizen communities, while complex bureaucratic procedure is the most critical issue in both countries and can significantly hinder the spread of energy communities. With respect to the different financial incentives available for the formation of energy communities in Italy and Spain, a few cases studies are hypothesized, calculating the most relevant cost-effectiveness indicators, e.g., Net Present Value. It turns out that a project with the same characteristics achieves greater economic feasibility in Italy than in Spain, depending on the type and size of incentives set by national laws and, above all, that financial incentives are necessary to make the formation of energy communities cost-effective and thus to achieve direct citizen involvement in energy transition actions.

“…In order to promptly support municipalities in their decision-making choices, it is necessary to suggest methods and approaches capable of assessing both efficiency and effectiveness of urban projects, in terms of sustainability and impacts as positive externalities. In urban projects, it is a real challenge for local administrations pursuing European objectives to assess the sustainability degrees of the generated impacts, and to measure the achievement of the required goals D'andria, Fiore and Nesticò, 2021;Nesticò et al, 2022;Oppio, Bottero and Arcidiacono, 2022;Dell'Anna et al, 2023). Literature has already deeply investigated the concept of sustainability, highly quoted by NRRP funds, through performance indicators: the Urban Sustainability Indicators (USIs) (Chao et al, 2020;Feleki, Vlachokostas and Moussiopoulos, 2020;Mangi et al, 2020;Amoushahi et al, 2022;Canesi and Marella, 2022;Robati and Rezaei, 2022).…”

The current economic situation has highlighted the difficulties and fragility of some previous programmatic choices, which have strongly penalized Italian marginal areas. This has been further aggravated by the Ukrainian conflict and by the lengthening of the pandemic recession. Local planning has often proved to be unsustainable in the long-term due to its lack of global sustainability. Local projects are frequently developed and realized in situations of contingent needs, tight deadlines, and by below-strength staff, which do not allow for adequate and accurate overall planning. These difficulties have emerged and have particularly increased during the past year with the rising strain of responding promptly to the copious National and European funds released in support of the dual transition, established by the European Union. In this situation, it seems mandatory to support the marginal areas in their transition process and in their responsive and conscious participation in the allocated funding. The expectation is to finance projects with positive impacts and with long terms sustainable effects on the peripheral territories, increasing their competitiveness but mostly their socio-economic well- being. The aim of this study was to prioritize, through a multicriteria model, different projects in marginal areas according to their sustainability impact levels, in line with the European goals. This paper proposes an Absolute Analytic Hierarchy Process (AHP) model through a targeted selection of Urban Sustainability Indicators (USIs) to define the degree of sustainability of different urban projects. and their ranking in accordance with the National Recovery and Resilience Plan (NRRP) Missions. By examining the efficiency of the allocation of funds in maximizing the expected quantitative-qualitative impacts on marginal areas, this study allows to verify policy objectives. This paper may support future models able of ranking a large scale of urban projects on their sustainability impacts in marginal regions. The definition of scales of priorities can therefore become a useful tool capable of assisting territories in applying awareness to funds for projects with high sustainable impacts. L’attuale congiuntura economica negativa, aggravata dal conflitto ucraino e dal protrarsi della recessione pandemica, ha fatto emergere le difficoltà e le fragilità di alcune scelte programmatiche del passato che hanno penalizzato le aree interne del paese. Spesso l’attuazione e la pianificazione locale si è rivelata non sostenibile nel lungo termine, evidenziando la criticità di alcune scelte a scapito della sostenibilità globale di sistema. Frequentemente gli interventi locali vengono attuati in situazioni di necessità contingenti, scadenze già sollecitate, ed organici sottodimensionati, che non permettono una corretta e adeguata indagine programmatica e d’insieme. Tali complessità sono emerse e si sono acuite particolarmente durante quest’ultimo anno, alla luce della difficoltà di rispondere pronta- mente e strutturalmente agli innumerevoli bandi emanati su fondi nazionali ed europei per attuare la transizione duale in accordo con le direttive e gli obiettivi stabiliti dall’unione Europea. Supportare le aree in- terne nel loro processo di transizione e quindi nella loro partecipazione responsiva e consapevole ai finanziamenti stanziati, assume, quindi, un ruolo rilevante e di grande responsabilità. L’auspicio è che gli innumerevoli finanziamenti vengano direzionati da parte dei territori periferici verso progetti di impatto e con ricadute sostenibili nel lungo periodo, incrementando, non solo la loro competitività, ma anche, attraverso la loro efficacia, il proprio benessere socioeconomico. Lo scopo del presente studio è quello di definire, attraverso l’applicazione di un modello multicriteri, la scala di priorità di diverse progettualità sulle aree interne secondo criteri di sostenibilità, in coerenza con i goals europei. Il presente contributo propone, attraverso la selezione mirata di indicatori della sostenibilità urbana (USIs), un modello Analytic Hierarchy Process (AHP) assoluto in grado di definire il grado di sostenibilità e quindi di priorità dei progetti in coerenza con le missioni del Piano Nazionale di Ripresa e Resilienza (PNRR). Tale analisi permette di verificare gli obiettivi di policy, esaminando l’efficacia della ripartizione dei fondi per una massimizzazione quanti-qualitativa degli impatti attesi sul territorio. Tale lavoro è il punto di partenza per la creazione di modelli in grado di offrire una classificazione della sostenibilità di molteplici interventi urbani da attuare sulle aree marginali. La creazione di scale di priorità può quindi diventare uno strumento in grado di assistere i territori nell’accedere ai finanziamenti con una programmazione consapevole di impatto sostenibile.
