Implementare il patrimonio archivistico: ricostruzione virtuale di una villa non realizzata di Giuseppe Samonà in Sicilia
2023
Questo saggio vuole essere una testimonianza dell’importanza culturale e cognitiva degli archivi (del progetto) intesi come patrimonio pubblico. L’azione di re-immaginarli può costituire un veicolo per la loro conoscenza? Con l’analisi di un caso-studio di un’abitazione non realizzata di un architetto del Novecento come Giuseppe Samonà si prova a verificare l’efficacia degli strumenti digitali per l’interpretazione dell’architettura come mezzi per l’implementazione comunicativa di un archivio.
Environmental assessment of 2030 electricity generation scenarios in Sicily: An integrated approach
2020
Abstract This paper deals with the environmental assessment of two electricity scenarios in Sicily, for 2030, characterized by a high exploitation of renewable energy sources in order to quantify the potential contribution of the local strategies in the achievement of the European climate policies and the potential improvement in the future electricity mix, compared to the current one (2014). In order to match these goals, authors integrate the Life Cycle Assessment with a scenario analysis. The future electricity mix scenarios, characterized by a share of renewables (57% for 2030-BS scenario and 51% for 2030-DS scenario) show a reduction of the greenhouse gases emissions per kWh of electri…

EDIFICI AD ENERGIA NETTA ZERO: UN CASO STUDIO ITALIANO
2011
L’industria, il sistema dei trasporti e l’edilizia sono i tre principali macro settori economici che più determinano un consumo di energia: In Italia, in particolare, ben il 30% dell’energia elettrica e il 40% di quella termica vengono impiegate nel settore civile d’utenza [1]. La necessità di ridurre i consumi energetici, determinata da sempre più restrittivi vincoli di natura ambientale e dal crescente costo dell’energia, gioca un ruolo importante nel modificare i canoni di progettazione e le modalità di manutenzione energetica degli edifici. Da ciò discende anche la crescente attenzione della comunità scientifica internazionale verso il concetto di Edificio ad Energia Netta Zero (EENZ), …
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…
Analysis of the effects of climate change on the energy and environmental performance of a building with and without onsite generation from renewable…
2020
Climate Change is a priority, due to the large variety of implications and importance that it may cause in the next decades. In this context, the building sector is a significant contributor to greenhouse gas emissions. For this reason, buildings should be designed in such a way that they are responsible for fewer GHG emissions. In this context, the paper analyses the potential impact of climate change on the energy performances of buildings, with and without onsite generation from renewable energy, using a prototype building located in Messina (Italy) as case study. The analysis is based on Intergovernmental Panel on Climate Change RCP scenarios and the results confirm the already known ov…
Environmental effects of energy policy in sicily: The role of renewable energy
2007
The saving of primary energy from fossil fuels and the promotion of exploitation of renewable sources are two of the most relevant goals to be achieved in order to match the climate protection target fixed by the Kyoto Protocol in 1997. For Italy, the commitment is the reduction of the greenhouse emissions by 6.5% below 1990 levels over the commitment period 2008–2012. It requires the introduction of suitable political strategies and programmes aimed to establish a sustainable energy system together with the application of a set of actions either at national scale, either at regional one. This study presents the results of a survey in the context of the Regione Sicilia about the potential s…
LCA of a solar heating and cooling system equipped with a small water–ammonia absorption chiller
2012
The development of renewable energy technologies is a critical tool for reducing climate change and the reliance on fossil fuels. However, renewable energy technologies cannot be considered totally clean because they require energy consumption and have environmental impacts that cannot be neglected during their life cycle. In this paper, the life cycle assessment methodology was applied to assess resource use and other environmental burdens related to the entire life-cycle steps of a solar cooling plant. The investigated system works with an absorption chiller assisted by a solar plant. Two back-up configurations (hot back-up and cold back-up) were examined in two localities: Palermo (south…
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…
An Intelligent Car Driver for safe Navigation with Fuzzy Obstacle Avoidance.
2009
In order to respond effectively to the environment uncertainties, autonomous vehicles are generally equipped with sensors. The proposed car guidance system is equipped with an intelligent controller, based on fuzzy logic, which calculates the speed and wheels orientation in order to follow a path while it is avoiding unknown obstacles. Better fluidity of driving are obtained using future-path, car dimension and car position prevision. Vehicle symmetries also speed-up and simplify the guidance system reducing the inputs and the rules numbers.
