Ville et fortifications : de l'héritage à la production du territoire urbain
2015
A large number of french cities host military historical edifices (citadels, barracks, bastions, defensive walls, etc.). Although their initial defensive functions have been lost over time, these edifices remain deeply rooted in the urban fabric of their host cities. They continue exerting an impact on these cities’ urban morphology and modern-time functions as well as the way in which the concept of city is understood. Cities nowadays face some new challenges,the increasing awareness of urban sprawl and its consequences, coupled with an urge to promote a renewed and sustainable urbanism, invites us to adopt new approaches to study urban fortifications. In addition to their symbolic aspect,…
Integrazione di celle solari di terza generazione nel vetromattone per la realizzazione di pannelli traslucidi fotovoltaici. Analisi prestazione e st…
2013
L’articolo illustra i primi risultati ottenuti nell’ambito dell’analisi prestazionale del vetromattone fotovoltaico, un prodotto edilizio innovativo derivato dall’integrazione di celle fotovoltaiche di terza generazione (DSSC) nel vetromattone, ideato per la realizzazione di involucri traslucidi energeticamente effi cienti ed “attivi”, in grado di ridurre i consumi energetici degli edifi ci e di produrre, al contempo, energia verde. L’analisi è stata condotta su quattro differenti ipotesi di integrazione. Attraverso simulazioni numeriche si è effettuata una valutazione dell’energia assorbita dagli strati attivi oltre che delle prestazioni ottiche complessive del dispositivo. Lo studio anali…
Evaluation of innovative thermal insulation systems for a sustainable envelope
2017
La memoria presenta i risultati ottenuti su sistemi di isolamento termico per l’involucro edilizio. Si presentano i risultati ottenuti tramite simulazioni informatiche che hanno consentito di verificare e ottimizzare la trasmissione del calore attraverso un sistema sottovuoto in vetro per le facciate trasparenti. Inoltre la possibilità offerta dal riciclo del materiale di scarto della potatura dell’Opunthia Ficus Indica (fichi d’india) che,opportunamente trattato ha permesso di ottenere un materiale isolante (Brevetto n. 1402131), in forma di pannello o in grani sfusi, (valori di coibenza termica 0.0710.057 W/mK). The paper presents the results of the research on thermal insulation systems…

FROM SCAN-TO-BIM TO HERITAGE BUILDING INFORMATION MODELLING FOR AN ANCIENT ARAB-NORMAN CHURCH
2022
Abstract. One of the most significant issues in Cultural Heritage is the management of ancient buildings to monitor their state of conservation or to plan actions in their maintenance; this issue can be now approached thanks to the use of the Scan-to-BIM process. This method allows the creation of parametric models into a BIM environment, which are capable of enhancing the geometrical representation of building elements and integrating different types of data.This paper shows the results of the research activities carried out by the Department of Engineering at University of Palermo (Italy) on applying the Scan-to-BIM approach to the survey and the modelling of an ancient Arab-Norman church…
The traditional sacral wooden construction in Lithuania. An illustrated catalogue of building techniques for the safeguard and recovery of cultural h…
2015
La Lituania attualmente può annoverare un patrimonio di circa 600 edifici sacri in legno ancora esistenti, sui quali, ad oggi, non sono stati condotti studi approfonditi in merito agli aspetti storico/architettonici e tecnico/costruttivi. Questa tipologia di edifici costituisce un patrimonio della cultura architettonica locale da esplorare e conoscere, per garantirne la corretta conservazione e valorizzazione. La maggior parte di questi edifici di culto in legno versa in condizione di degrado poiché le comunità non sempre possiedono la dovuta attenzione e le competenze tecniche capaci per salvaguardare tale patrimonio. Le cause più frequenti di danno derivano da una inadeguata manutenzione,…
Paving the way for the Paris Agreement:Contributions of SDEWES science
2023
Today, coal is responsible for 40% of annual CO2 emissions. At the same time, global warming causes climate changes accompanied with catastrophic meteorological phenomena all over the world. After the 2015 Paris Agriment many countries set ambitious energy policy to reduce the annual greenhouse gas emission. The 2021 UN Climate Change Conference, COP26 - Glasgow, ended with the adoption of a less stringent resolution than some anticipated: countries only agreed to “phase down” rather than “phase out” coal. Is possible the realization of the Paris Agreement after COP-26? For achieving this ambitious targets in such conditions, the support of the multi-disciplinary scientific knowledge is nee…
Recent advances in methods, policies and technologies at sustainable energy systems development
2022
Following the 2015 Paris Agreement and other agreements which have been signed after, sustainable energy development is becoming the major goal in many countries. EU have set the targets to reduce the annual greenhouse gas emission by 40% in 2030 and 80% for 2050 compared with 1990 levels. For achieving this ambitious energy policy, three major technological changes are available: energy savings on the demand side, efficiency improvements in the energy production, and replacement of fossil fuels by various sources of renewable energy. Also, for realization cited three major technological changes the support of the multi-disciplinary scientific knowledge is needed. Therefore, from the beginn…
Mediating role of job satisfaction, affective well-being and health in the relationship between indoor environment and absenteeism: work patterns mat…
2018
BACKGROUND: Office workers spend long hours in their workplace, and these environments impact their well-being and performance. This relationship can involve different mediation chains. The degree of complexity of this relationship can vary depending on different types of office work (work patterns) employees carry out. OBJECTIVE: To analyze the relationship between indoor environment and absenteeism, and the mediating role of job satisfaction, affective well-being, and health, in different work patterns. METHOD: 1306 office workers from different European countries were classified into work patterns depending on: task complexity and interactivity. RESULTS: Job satisfaction, affective well-…
Load match optimisation of a residential building case study: A cross-entropy based electricity storage sizing algorithm
2015
Abstract The EU EPBD recast regulation marked the application of the net zero energy building (Net ZEB) concept in all fields of building construction in Europe as a building able to generate as much energy as it consumes over a selected time frame. A more detailed insight is however needed, as even if a building achieves a long-term energy balance between energy generated and consumed, smaller time scales must also be considered. For example, from the utility’s point of view, if a Net ZEB is a heavy consumer in the winter, it will appear to be quite similar to a conventional building, requiring the use of additional generation. The increase in the generation-load match means reducing the s…
