MIGLIORAMENTO TECNOLOGICO-PRESTAZIONALE DI UN COMPONENTE INNOVATIVO PER L’INVOLUCRO EDILIZIO - PERFOMANCE IMPROVEMENT OF AN INNOVATIVE BUILDING COMPO…
2016
L’articolo illustra l’attività di ricerca che gli autori, cofounder della SBskin. Smart Building Skin s.r.l., start up innovativa e spin off accademico dell’Università degli Studi di Palermo, stanno conducendo al fine di ottimizzare le performance energetiche di un componente innovativo per facciate e coperture di edifici (dagli stessi brevettato) in grado di ridurre i consumi energetici e di produrre energia pulita dal sole. L’attività che qui si illustra è stata finalizzata all’ottimizzazione del design dei sub-componenti che contribuiscono alla realizzazione dei pannelli traslucidi multifunzionali (realizzati con vetromattoni innovativi, preassemblati a secco e precompressi) ed alla scel…
Solai ad orditura metallica. Per una storia della costruzione
2016
Sommario: Il saggio approfondisce gli aspetti storici e costruttivi dei solai ad orditura metallica dalla fine del XVIII secolo all’ultima guerra. Dopo una parte generale in cui vengono delineate le motivazioni e le fasi iniziali dell’uso dei materiali ferrosi in edilizia, si traccia ed analizza una serie di linee evolutive della trave metallica, fino al raggiungimento della sezione a doppio T che, a pieno titolo, si considera il punto di arrivo della ricerca sulla forma più conveniente per evidenti motivi di efficienza statica, pur coi successivi affinamenti nella produzione, nel calcolo e nella messa in opera. Si è ipotizzata l’evoluzione attraverso le strade della combinazione legno-ferr…
Recensione a:Tra tecnica e natura. Problemi di ontologia del vivente in Heidegger, di L. Illetterati, Il Poligrafo,Padova 2002

recensione al testo di Luca Illetterati che analizza il concetto di tecnica dal punto di vista heideggeriano con riferimento al saggio sul concetto di "natura".
The muqarnas ceiling of the Palatina Chapel in Palermo
2018
St. Peter’s Basilica inside the Royal Palace of Palermo, known as the Palatina Chapel, is one of the most popular medieval monuments in Sicily. Built between 1130 and 1163, it contains interesting wooden framings that represent both bearing and finishing structures. Studies about the Arab-Norman church have often concentrated on the very rich and suggestive decorative mosaic apparatus of walls and floorings, as well as the pictorial cycle of wooden ceilings. Knowledge about the constructive techniques adopted and, in particular, about the realization of the coverings, is very limited: there are wooden floors built at different levels, vaults and wooden ceilings and among these is the portio…

SCAN-TO-BIM FOR THE MANAGEMENT OF HERITAGE BUILDINGS: THE CASE STUDY OF THE CASTLE OF MAREDOLCE (PALERMO, ITALY)
2020
Abstract. Conservation and preservation of heritage buildings require the knowledge and sharing of a great deal of data and information about buildings. Such information comes from the different disciplines involved in the restoration and maintenance processes. The integration and use of all this information in a single working environment is a key factor for the success of historical building conservation and management projects. Heritage (or Historic) Building Information Modelling (HBIM) is nowadays the most appropriate tool to collect and manage all data related to Architectural Heritage. The HBIM process requires an in-depth knowledge of the historical building that can be achieved usi…
Experimental Investigation on the Performances of Innovative PV Vertical Structures
2019
The sustainable development of our planet is considerably related to a relevant reduction of CO2 global emissions, with building consumption contributing more than 40%. In this scenario, new technological conceptions, such as building-integrated photovoltaic technology, emerged in order to satisfy the requirements of sustainability imposed by the European Union. Therefore, the aim of this work is to provide a technical and economical comparison of the performances of different vertical-mounted innovative photovoltaic systems, potentially integrated on a building instead of on traditional windows or glass walls. The proposed investigation was carried out by means of experimental tests on thr…
Sustainability in the restoration and management of the historic architecture in Palermo
2015
This research investigates the energy and environmental sustainability in the restoration and conservation of historic buildings. It focuses on the architectural heritage of Palermo, which can be a significant case study for the Mediterranean area. Its objective is to analyse the current energy performance of this historic architecture and its potential for energy improvement. Therefore, it aims at proposing a methodology to combine the enhancement of energy and environmental performances of the historic architecture of Palermo with the need of its material and aesthetic conservation, in the frame of the current regulations.
Rebuilt the space using stone or brick vaulted systems: catching the contemporary challenge of construction tradition
2019
In the recovery and restoration sites, as well as in the versatile word of university research about construction history, its not infrequent to study stereotomy for the re-proposal of stony or tiled vaulted systems, sometimes complex for their constitutive geometry, equipment, preliminary/subsidiary carpentry works. It represents a didactic study-key also in Engineering and Architecture Schools, through laboratories that teach to future designers a know-how that can be easily spent in their professional repercussions.
Innovative, Translucent and Multi-functional Components for the Building Envelope: technological and performance optimization
2017
The paper describes the actions aimed at the technology and performance optimization of an innovative, multi-functional building component made of precast and pre-stressed glass blocks useful for the construction of sustainable building envelopes able to reduce the energy consumption and to produce clean energy from the sun. The design optimization of different sub-components and the choice of the right materials for guaranteeing their good response in terms of mechanical resistance, thermal and acoustic insulation, light transmission, electricity production, integration with other components, dimensional coordination, are particularly described.
