Birth and affirmation of the principle of "minimal intervention" in the practice of restoration in the United Kingdom (19th c.)
2014
This paper traces the history of nineteenth-century restoration in the UK by high-lighting the events, theories and documents that will lead for the first time in Eu-rope at the maturation of the restoration discipline. The world of architecture and the possibility of a physical survival of monuments found a professional and ethi-cal dimension that can be considered sustainable in many subjects. The confusing and arbitrary stylistic restoration, with all its contradictions and unruly, is recog-nized as a deleterious practice to the conservation of ancient buildings. Some architects addressing the restoration to the stylistic unity became the target of a growing collective movement that chal…
Per il sistema difensivo di Rodi "insigne monumento cioè di tutta la città murata"
2016
Tra la seconda metà del XIX sec. e l’inizio del XX sec. in Europa si assiste alla progressiva distruzione dei sistemi difensivi delle città, in quanto, oramai, considerati inutili ingombri rispetto ai motivi che li avevano originati. Delle fortificazioni delle città, solamente alcuni elementi furono conservati, come, ad esempio le porte urbiche e alcune torri. In particolare la città di Rodi, in Grecia, fino all’arrivo degli occupanti italiani, nel 1912, possedeva un sistema di fortificazioni formato da mura, bastioni, fossati e terrapieni. Quest’ultimi, dopo più di duecento anni, dalla conquista dello stato dei Cavalieri di Rodi, erano stati adibiti a cimiteri israeliani e musulmani. Con l…
Politiche e disposizioni per il ripopolamento dei piccoli centri abbandonati. Alcune riflessioni
2020
The contribution constitutes an introduction to one of the sections of the conference, which highlights the need to put in place, on the issues in question - the depopulation of inland areas - a pre-eminent pedagogical-formative action that helps communities to reverse their gaze by considering small towns a resource.
Comunicare il restauro
2017
The crisis in values and the political-economic problems that plague modern-day society affect, among other things, the topic of architectural heritage protection and enhancement. Given its role as a historic trace of thousand-year-old civilisations, cultural heritage has often been liable to exploitation for religious, political as well as cultural purposes. For this reason, traditional conservation instruments are inadequate if we want to tackle modern-day circumstances, and those who work in the field of conservation should now play an important role not only in the concrete protection of this heritage (through conservation, maintenance, reuse and so on), but also in finding new cultural…
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…
An empirical approach for ranking environmental and energy saving measures in the hotel sector
2009
The energy demand of the hotel sector of an Italian region is here utilized for hierarchizing, by means of an empirical method, efficient measures devoted to energy saving and reduction of CO2 emissions. Due to the large number of consumers present in the selected territorial area and the lack in detailed data, the energy demand assessment is here carried out by the analysis of a sample of representative consumers. A short set of indexes, referring to energy and environmental performances, are defined and calculated for different clusters of hotels, grouped on the basis of site characteristics, opening periods, number of beds, and building age. Such indexes are utilized to establish lists o…
A model for predicting the potential diffusion of solar energy systems in complex urban environments
2011
Abstract The necessity to reduce greenhouse gases emission produced by energy building consumptions and to cut the energy bill (mainly due to the use of fossil sources) leads to the employment of renewable energy sources in new planned scenarios. In particular, more and more often municipal energy and environmental plans pay great attention to the possibilities of employment of the solar technologies at urban scale. Solar thermal and photovoltaic (PV) systems are, by far, the most suitable tools to be utilized in urban areas. Obviously, the proper adoption of such systems in buildings does call for the availability of calculation methods suitable to provide the actual level of exploitation …
Polymer-coated Nanolimes Dispersions for Reduction, Deacidification and Consolidation of Ancient Paper
Nanolimes have been widely explored as nanomaterial for cultural heritage preservation. In particular, they have shown interesting properties to contrast the ageing of manuscripts, books and artistic works, opening up the possibility to store such items in a good quality state for longer. In the present work we reported an innovative nanolime-based formulation for paper restoration, which includes in its composition a reducing agent and a fibers consolidator as well. To formulate an efficient product, we deeply investigated the cellulose oxidation process with a multi-technique approach. The here presented formulation consists in a hydroalcoholic ternary dispersion of nanolimes coated with …
An Adaptive Bayesian System for Context-Aware Data Fusion in Smart Environments
2017
The adoption of multi-sensor data fusion techniques is essential to effectively merge and analyze heterogeneous data collected by multiple sensors, pervasively deployed in a smart environment. Existing literature leverages contextual information in the fusion process, to increase the accuracy of inference and hence decision making in a dynamically changing environment. In this paper, we propose a context-aware, self-optimizing, adaptive system for sensor data fusion, based on a three-tier architecture. Heterogeneous data collected by sensors at the lowest tier are combined by a dynamic Bayesian network at the intermediate tier, which also integrates contextual information to refine the infe…
