'Aquarum deliciae' nei palazzi dei re normanni a Palermo
2022
Il lavoro illustra il forte legame esistente tra gli edifici dei re normanni a Palermo -in particolare i “sollatia”, in cui amavano rifugiarsi, con la loro corte, per cacciare e ripararsi dalla calura estiva, immersi nella rigogliosa vegetazione dei grandi parchi che dalla città si estendevano fino alle pendici della rocca di Monreale e su tutta la cosiddetta piana dei colli- e l’acqua. El estudio ilustra la fuerte nrelación entre los edificios de los reyes normandos en Palermo –en particolar los “sollatia”, en los cuales amaban refugiarse, con su corte, para cazar y reposar del calor estival, inmersos en la exhuberante vegetación de los grandes parques que desde la ciudad se extendían hast…
Centrale elettrica in via Alessandro Volta
2015
Il primo nucleo della centrale elettrica di Via Alessandro Volta venne realizzato nel 1899 in un’ampia area del molo trapezoidale ceduta in concessione alla Schuckert & C. di Norimberga. Prima dei bombardamenti aerei del 1943 la centrale, nella configurazione di maggiore estensione, era composta dalla palazzina per uffici ed abitazioni costituita da tre elevazioni fuori terra ed un piano semicantinato, coerente e tipologicamente conforme alla funzione che ospitava, e dai locali che connotavano non solo funzionalmente ma anche architettonicamente la specificità dell’impianto: la sala caldaie, distillatori e pompe, la sala macchine ed il locale quadro e accumulatori. Dopo la fine della guerra…
Analytical studies of the Sirocco room of Villa Naselli-Ambleri: A XVI century passive cooling structure in Palermo (Sicily)
2015
Abstract This work focuses on a passive cooling architecture particularly popular from the Renaissance in Palermo area, as building sumptuous suburban villas became a real hobby for the Sicilian aristocracy. A Sirocco room is an artificial subterranean construction, built close to a water spring in order to reproduce the pleasant conditions of freshness that could be experienced in a natural cavern. In these places, nobles used to spend their time with friends to escape from the hot summer. The room of Villa Naselli-Ambleri is nowadays the best preserved in Palermo thanks to its owners’ conservation care and it is unique for its cooling operating principle. The above-mentioned consideration…
Conflicting needs of the thermal indoor environment of museums: In search of a practical compromise
2008
Thermal indoor microclimate conditions in museum buildings refer to two important requirements: the preservation of works of art and the comfort of visitors to these buildings and/or those working inside them. Unfortunately, different works of art have different internal parameters which render the management and control of the indoor thermal microclimate difficult. In this work the values proposed by various standards for the thermal environment of museum buildings have been revised. Moreover, the indoor microclimatic conditions relating to people's comfort have been described, with the aim of singling out possible common ranges for these parameters. With this aim, a useful simultaneousnes…
Two operative risk indicators as tools for negotiating contracts between curators of Museums and HVAC technical services providers
2020
Abstract The purpose of Heating, Ventilating and Air-Conditioning (HVAC) systems in museums is to properly control important microclimate parameters; such systems, in fact, apart from ensuring the visitors’ wellbeing, are requested to guarantee suitable indoor conditions for the proper conservation of the important cultural goods hosted by museums. Hence, in case of disservice, or interruption due to maintenance interventions, it is important to quantify the economic damage induced to exhibited and/or stored works of art (or even to the building museum itself). Accordingly, it is essential to guarantee the shortest possible period of disservice during which probable damages for the works of…
A bottom-up harmonized energy-environmental models for europe (BOHEEME): A case study on the thermal insulation of the EU-28 building stock
2021
Abstract The paper presents a methodological approach, called “BOttom-up Harmonized Energy-Environmental Models for Europe” (BOHEEME), that combines bottom-up modeling, energy dynamic simulation, and life cycle assessment for evaluating and comparing the energy and environmental effects of different renovation strategies of the residential EU building stocks, from micro to the macro level. The study defines 672 building models representative of the residential EU-28 building stocks built before 2010, called archetypes, and the improvement of their envelope, applying different insulation materials from a traditional one to bio-based materials and studying their environmental effects via LCA.…
HISTORIC URBAN CENTERS. CONSTRUCTION CHARACTERS AND SEISMIC VULNERABILITY
2018
Parallelamente alla redazione di una micro-zonazione sismica che evidenzi le differenti risposte al sisma che i vari ambiti offrono in termini di amplificazione delle onde sismiche al suolo, in relazione alla stratigrafia e all’orografia del terreno, si rivela fondamentale conoscere e prevedere gli effetti di un sisma sul sistema urbano. È fondamentale quindi effettuare un’analisi del patrimonio costruito esistente al fine di conoscerne le caratteristiche, valutarne il livello di vulnerabilità ed individuare una scala di priorità di intervento, approfondendo in particolare l’indagine sui centri storici, contesti di particolare complessità, interesse storico e potenziale vulnerabilità. A par…
From recovery manuals to historic and construction building information modeling (h-BIM). Strategies for historical Sicilian centres
2018
Il recupero dei centri storici costituisce oggi, oltre che un obiettivo prioritario di qualsiasi politica urbana, anche una attività di grande interesse strategico ed economico. Molte sono state le ricerche e le politiche di sostegno concernenti interventi sull’esistente, dettate da una sensibilità per il recupero del patrimonio edilizio della città storica; ciò ha reso necessario l'analisi e lo studio specifico delle tecniche costruttive. Nonostante il complesso quadro normativo e vincolistico, gli interventi sui centri storici continuano però ad essere in molti casi condotti in maniera impropria. L’uso di materiali e tecniche incolte, trasferite dal cantiere moderno a quello di recupero, …
Artificial neural network decision support tool for assessment of the energy performance and the refurbishment actions for the non-residential buildi…
2017
The public buildings sector represents one of the most intensive items of EU energy consumption; the application of retrofit solutions in existing buildings is a crucial way to reduce its impact. To facilitate the knowledge of the energy performance of existing non-residential buildings and the choice of the more adequate actions, Public Administrations (PA) should have the availability of proper tools. Within the Italian project "POI 2007-13", a database and a decision support tool, for easy use, even to a non-technical user, have been developed. A large set of data, obtained from the energy audits of 151 existing public buildings located in four regions of South Italy have been analysed, …
Energy and environmental assessment of heritage building retrofit
2020
In the transition to a low-energy economy, the building stock renovation should address the reduction of the environmental impacts, by means of suitable energy retrofits oriented to meet current energy efficiency regulations, construction guidelines, and standards on comfort and operation. With regard to the historic segment of the building stock, suitable refurbishment policies are needed to avoid the loss of their heritage values, even if this is a complex issue requiring interdisciplinary approaches, dedicated diagnostic procedures, and specific tools. In this paper a suitable method for energy and environmental assessment specifically devoted to historical building retrofit, following a…
