Il ruolo della Life Cycle Assessment nella decarbonizzazione del 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

Life Cycle Inventory e qualità dei dati
2017
L’analisi di inventario, LCI, è la fase della LCA che comprende la compilazione è la quantificazione dei flussi in entrata e in uscita per un dato sistema di prodotto con riferimento al suo ciclo di vita. Scopo principale di questa fase è la computazione di tutte le materie prime che sono state impiegate e la stima delle emissioni in aria, acqua e suolo che sono state generate durante l’intero ciclo di vita del sistema in esame. Il capitolo descrive i principali approcci metodologici connessi al LCI, le tipologie e la qualità dei dati impiegati nell’analisi.
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…
Life-Cycle Assessment of Buildings
2019
The chapter presents a complete overview of LCA applied to buildings. After a brief introduction on the origin and developments of the LCA, it describes four steps of the LCA methodology, according to the framework of the International standards of ISO 14040 series. Then, the authors focus on the LCA applied to the building sector and on the standard EN 15978. They identify the main issues related to the application of the methodology to buildings, such as the selection of the functional unit, the systems boundaries,the environmental indicators, etc. In the context of the sustainability, a brief overview on the economic and social aspects of buildings and on the available building life-cycl…
