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…

CLCA for Assessing Environmental Impacts of Power Sector in the GHG Policy Context
2020
Purpose: Current greenhouse gas (GHG) policy aims at reducing emissions from power sector. However, there are some known trade-offs of GHG emission reductions, in terms of other types of environmental impacts and impacts on other economic sectors. Consequential life cycle assessment (CLCA) has been developed to assess the environmental impacts of the power sector in relation with changes in the policy and its indirect impacts on other economic sectors. Methods: A systematic review of CLCA method is conducted in the power sector. CLCA studies since 2005 are reviewed in terms of obtained results and methodology to identify whether CLCA is a more suitable approach for assessing environmental i…
A Review on Consequential Life Cycle Assessment in the Power Sector
2020
The existing policy for greenhouse gas (GHG) abatement aims at decarbonisation of the power sector. The interrelations between the power sector and other economic sectors raise a question of whether the GHG emission reduction policy in the power sector is as effective as it is claimed. Consequential life cycle assessment (CLCA) has been developed to assess the environmental impacts of any industrial/productive sector in relation with changes in the policy and its indirect impacts on other economic sectors. This review is conducted on CLCA studies in the power sector in terms of system boundaries expansion and socio-economic interactions and the ability to quantify indirect environmental imp…
Environmental assessment of a new building envelope material derived from urban agriculture wastes : the case of the tomato plants stems
2023
Abstract Purpose Decarbonizing cities is one of today’s biggest challenges. In this regard, particular attention has been paid on improving the environmental performance of buildings. In this framework, this work consists in assessing the environmental impact of an innovative building envelope component derived from urban agriculture (UA) wastes. In fact, rooftop UA seems to be a possible solution to the rising food demand due to increasing urban demographic growth. Consequently, rooftop UA wastes need to be treated in sustainable ways. Methods This study aims to determine the carbon footprint and embodied energy of a new infill wall material, derived from UA wastes produced by a building r…

ECO-PROFILES OF INNOVATIVE ENERGY SYSTEMS FOR DOMESTIC AND RESIDENTIAL APPLICATIONS
2015
The exponential growth of distributed generation systems (mainly from solar energy through the use of photovoltaic) and the new release on energy markets of new generation technologies, with smaller dimension, are pushing towards rethinking energy systems. "Smart buildings" with the capacity to produce, store and manage flow of information's and energy will become the milestone of the future distribution networks (smart buildings to smart grid). The goal of this study is to evaluate the ecoprofile of 1 kWh of electricity, selected as a functional unit, generated by microcogenerator fuel cells as SOFC. The analysis was performed using the Life Cycle Assessment methodology, which allows to co…
