La LCA di sistemi di accumulo impiegati nel settore edile
2017
L’edilizia è uno dei settori più rilevanti in termini di produzione di ricchezza e di occupazione, ma è anche responsabile di significativi consumi di risorse naturali e impatti ambientali. Si stima, infatti, che nell’Unione Europea l’edilizia sia responsabile del 50÷60% del consumo di risorse naturali, e tali percentuali sono destinate ad aumentare senza l’avvio di strategie e azioni orientate alla riduzione dei consumi di combustibili fossili e alla promozione delle risorse rinnovabili. Per migliorare l’eco-profilo del settore edile, la riduzione del consumo di risorse e la minimizzazione degli impatti ambientali negli ultimi anni costituiscono gli obiettivi principali da perseguire nella…
Life cycle energy sustainability assessment: an expanded framework for energy technologies
2018
Life Cycle sustainability assessment is one of the most relevant tools delving in sustainability science, based currently on the triple bottom line idea, that is identified in the use of the three tools of Life Cycle Assessment (LCA), Life Cycle Costing (LCC) and Social Life Cycle Assessment (S-LCA). The methodology is structured on international regulations and is currently being applied to a wide set of products and systems. However, when targeting specifically energy technologies with this methodology some specific issues need to be taken in consideration before applying tout court the standard LCSA methodology. Energy systems – in particular those where fluid streams are used – have an …
Life Cycle Assessment of solar heating and cooling systems: the tool “ELISA”
2018
Solar heating and cooling (SHC) systems play an important role in the achievement of energy and climate European goals. The benefits of these technologies should be evaluated taking into account their lifecycle energy and environmental impacts, calculated by applying the Life Cycle Assessment (LCA) methodology. The development of a complete LCA can be difficult and time-consuming particularly for no-LCA experts, discouraging them in the inclusion of the lifecycle perspective in their assessments. To overcome this limit, the paper presents “ELISA - Environmental Lifecycle Impacts of Solar Air-conditioning systems”, a user-friendly simplified tool for estimating the lifecycle energy and envir…
The role of LCA in reporting emission inventories for municipalities: experiences from the Convenant of Majors

A Mathematical Model For Evaluating Energy Consumptions In Life Cycle Assessment.
2014
This paper takes up the ecobalance topic giving prominence to a calculation procedure of necessary energy consumptions for the production of a product in the different phases of a whole life cycle. Are used to identify all stages of the life cycle are determined and simplified formulas for the calculation of specific energy consumption. Is also examined a case where the components of the final product are up to 8. The model is valid for any type of product and through operations research (ie, placing constraints on the variables) you could get to optimal solutions minimizing the objective function.
An overview of sustainability issues in manufacturing and building sector: a life cycle assessment approach
2014
In the latest decades, the industrial consumption of materials and energy has undergone a growth which may exceed the limits of earth resources. Therefore, a strong awareness of the need to use materials and energy in a more efficient way has arisen. A wide research interest on sustainability is present in the modern technical literature: Life Cycle Assessment (LCA) methodology and Design for Environment (DFE) procedures are nowadays widely investigated in many research labs all over the world. In this context, this paper focuses on LCA approaches in two main fields: manufacturing and building sector. As the former is regarded, sustainability issues are crucial topics and the reduction of e…
Life cycle assessment of a solar PV/T concentrator system
2011
The paper shows the energy and environmental analysis of a solar low Concentrating Photovoltaic-Thermal (CPVT) system, installed on the roof of the Energy Department building at University of Palermo (Italy). LCA methodology was applied to assess the whole life-cycle of the selected Functional Unit. Data survey from the producing company regarding the consumption of energy sources and of materials were developed. The assessment allowed to identify the steps and the system components addressing the highest energy and environmental impacts. Energy and environmental benefits and drawbacks related to the CPVT system. The research was developed within the National Relevant Research Programme (PR…
Resource depletion of a Lithium ion battery cell technology
2018
Lithium-ion batteries (LIBs) are the dominating storage technology for electric vehicles (EVs). Different types of LIBs, using diverse cathode materials are available in the market, such as LiMn2O4, Li(Ni1/3Co1/3Mn1/3)O2. The cathodes contain a wide range of raw materials (RMs), among which e.g. cobalt is in the 2017 list of CRMs for the Europe Union (EU). CRMs are both of high economic importance for the EU, and vulnerable to supply security. In the last years, the increasing demand of LIBs has triggered a growing interest in the need to ensure the security and the sustainability of the supply of the CRMs used in LIBs and in general in EVs. In this context, lithium rich layered oxides from…
Luminescent Solar Concentrator (LSC): principio di funzionamento e fasi preliminari dell’analisi LCA applicata alla Smart Window-LSC
2019
Una delle tecnologie più promettenti nel panorama dei sistemi fotovoltaici integrati negli edifici è quella dei concentratori solari luminescenti (LSC - Luminescent Solar Concentrator). La peculiarità di questi dispositivi risiede nel fatto che possono essere installati in zone dell’edificio difficilmente sfruttabili da altre tecnologie fotovoltaiche, in particolare in sostituzione di aperture quali lucernari o finestre, grazie alla loro caratteristica di essere semi-trasparenti e di funzionare sia con radiazione solare diretta che diffusa. L’obiettivo del presente lavoro è stato ricostruire i percorsi di produzione dei principali componenti del pannello LSC, in modo da ottenere un parziale…
Life cycle assessment of solid oxide fuel cells and polymer electrolyte membrane fuel cells: A review
2017
Fuel cells (FCs) are among the key technologies that Europe will have to rely on in order to comply with the most recent environmental targets inspired by decarbonization and circular economy. The assessment of the real advantages of using FCs for producing energy must include a reliable analysis of the energy and environmental impacts during the life cycle of these systems, including the raw materials supply, production, use, and disposal. In this context, the life cycle assessment (LCA) is a well-established methodology for assessing the eco-profile of products and services and for identifying the components and the life cycle steps having the largest contribution to energy and environmen…
