ANN modelling of CO2 refrigerant cooling system COP in a smart warehouse
2020
Author's accepted manuscript Industrial cooling systems consume large quantities of energy with highly variable power demand. To reduce environmental impact and overall energy consumption, and to stabilize the power requirements, it is recommended to recover surplus heat, store energy, and integrate renewable energy production. To control these operations continuously in a complex energy system, an intelligent energy management system can be employed using operational data and machine learning. In this work, we have developed an artificial neural network based technique for modelling operational CO2 refrigerant based industrial cooling systems for embedding in an overall energy management s…
Are green bonds a different asset class? Evidence from time-frequency connectedness analysis
2021
Abstract This paper investigates the time-frequency connectedness across the global green bond market and several mainstream financial and energy markets in an attempt to figure out whether green bonds represent a different asset class. The connectedness methodology proposed by Barunik and Křehlik (2018) is employed for that purpose. This approach enables quantifying the dynamics of connectedness in terms of return and volatility over time and across time scales simultaneously. The empirical results indicate that connectedness between the global green bond market and the conventional financial and energy markets mainly occurs at shorter time horizons, suggesting that shocks are rapidly tran…
Assessing the economic profitability of Paulownia as a biomass crop in Southern Mediterranean area
2022
The increase of renewable energy production worldwide, occurred in the last years, is also attributable to some agroforestry species cultivated according to the short rotation coppice technique. Although these species are able of enhancing abandoned or marginal land leading to numerous environmental benefits, an increasing number of farmers are introducing them in place of agricultural crops. Therefore, since for a farmer economic sustainability is one of the main factors to introduce a biomass crop, the study aimed at evaluating the profitability of Paulownia, a species that has been spreading in recent years. In particular, an economic analysis has been carried out in a Southern Italian f…

Agroalimentare e sviluppo economico sostenibile: energia, efficienza energetica, ambiente e cibo
2013
Nell’ultimo decennio, il sistema agroalimentare nazionale nella sua accezione più ampia di agricoltura e industria alimentare, ha assunto una configurazione fortemente sistemica, aperta al contributo di diverse discipline e tecnologie. Tale evoluzione ha consentito al sistema agricolo di raggiungere posizioni ragguardevoli se consideriamo che nel complesso l’agroalimentare rappresenta per l’economia italiana un valore di 250 miliardi €, pari a circa 16% del PIL. Il mondo agricolo, nel suo complesso, costituisce ormai uno snodo fondamentale per attività che riguardano: l’energia, l’ambiente, il cibo, il territorio, il benessere dei cittadini, il sistema economico aree urbane-aree rurali. Il …
Circular business models for lithium-ion batteries - Stakeholders, barriers, and drivers
2021
Abstract Business models for the circular economy, or circular business models, is a growing field of research applied in various industries. Global sustainability trends, such as electrification of the transport sector and increased energy consumption from renewable sources, have led to rapid growth in the number of batteries produced, especially lithium-ion based batteries. Sustainable lifetime management, including end-of-life, needs development to avoid social and environmental harm and potentially to recapture economic value as the use of these batteries increases. Current research primarily focuses on technical and economic issues based on recycling and the second use of batteries rat…
Integration of green roofs&walls in urban areas
2020
Growing urbanization is associated with the emergence of environmental problems, such as the reduction of natural resources, the atmosphere pollution and the increase of the heat islands phenomenon in cities. The integration of vegetation in the urban areas, through the creation of green hanging systems, represents a possible solution to improve the energy sustainability of buildings, to combat meteoric excesses, to improve stormwater management and to reduce pollutant levels. These energy and environmental benefits are related to the properties of evapotranspiration, shading and thermal insulation of the vegetation. The work reports the results of the main studies concerning the use of han…
Green infrastructures for the energetic and environmental sustainability of cities
2019
The inexorable extension of urbanization is consuming huge amounts of soil drastically reducing natural vegetation, replacing it with buildings and low albedo surfaces. The changes due to the different thermal properties of surface materials and the lack of evapotranspiration in urban areas lead to a phenomenon known as "urban heat island effect". By reintroducing the vegetation back into the urban landscape, a partnership between nature and cities should be strengthened to create a new sustainable urban environment. Since the outer surfaces of building offer a great amount of space for vegetation, planting on roofs and walls has become one of the most innovative way to provide several envi…
Evaluation of the optimal renewable electricity mix for Lampedusa island: The adoption of a technical and economical methodology
2020
Abstract Worldwide, the majority of small islands not connected to the main grid is still dependent on fossil fuels. From an economic and environmental point of view, this condition is no more sustainable given the high costs for electricity generation and the high level of pollutant emissions. Furthermore, the dependence on fossil fuel represents a risk for the security of the supply of several small developing Countries since they are obliged to import those resources from foreign Countries. The introduction of renewable energy sources in small islands represents a valid solution to solve these problems. In this context, the paper investigates the case of Lampedusa, a small Italian island…
Performance-based research funding: Evidence from the largest natural experiment worldwide
2023
A performance-based research funding system (PRFS) is a nationwide incentive scheme that promotes and rewards university research performance through competition for government funding. The UK’s PRFS, currently the Research Excellence Framework (REF), is considered the oldest, largest and most developed payment-by-results system in academia worldwide. Surprisingly, and despite the strong criticisms, little has been done to quantitatively and casually evaluate the intended and unintended effects of the PRFSs. In this paper, we evaluate the incremental impact of the REF 2014 in the fields of Economics and Business. We use a synthetic control method to compare the performance of UK universitie…
