Institute of the Holy Heart in Palermo. Architectural and technological proposal of rehabilitation intervention for post-pandemic social housing.

2021

Close to the historical city centre, the prince Pignatelli built his villa-palace in the 18th century. Later it became the headquarter of the Order of the Holy Heart that instituted a school attended by the highest society. The 11430 m2 historical building (ground floor, first and second floor), along with its monumental garden (about 9600 m2), was abandoned by the nuns in 2008. The novel ownership is aimed at restoring and re-functionalising the complex, a kaleidoscope of urban-architectural and technological stratifications, located in a crucial point of Palermo still waiting for a new season of requalification, being also close to the Zisa castle, included in the UNESCO Arab and Norman i…

Tecniche di Produzione del Cemento Traslucido

2012

The aim of the paper is to investigate different techniques used by some companies nowadays involved in the production of panels or blocks made of translucent cement. For doing that, the patents registered all over the world starting from the 2000 have been studied in deep, in order to acquire more detailed information about the techniques of production and to overcome the limits due to the lack of information about this subject that is difficult to find in literature. Particularly, patents by LitraConTM, Luccon, Lucem, Italcementi have been investigated; these last four industries are, at the moment, the only ones able to make in Europe translucent cement elements by using different techni…

L'articolo illustra le diverse tecniche di intervento per il recupero dei solai più diffusi nell'edilizia corrente, evidenziate da un'indagine comparativa sperimentale. Modelli, materiali ed esiti della ricerca.

Pannelli traslucidi preassemblati “a secco” e precompressi realizzati con vetromattoni “modificati”

2011

L’articolo illustra le problematiche connesse al progetto di un pannello preassemblato a secco e precompresso realizzato impiegando vetromattoni “modificati”, energeticamente efficienti. Tra le 21 nuove configurazioni del vetromattone individuate è stata indagata per via analitico-sperimentale quella più efficiente dal punto di vista energetico, al fine di valutarne la resistenza meccanica e conoscere lo stato deformativo che si genera nel giunto adesivo tra conchiglie di vetro e “cintura termica”.Per realizzare un taglio termico tra le due conchiglie di vetro e consentire l’inserimento di una o più lastre all’interno dell’intercapedine del vetromattone è stata, infatti, progettata una “cin…

Upside-down ship’s kel-shaped vaults as a contemporary design criteria. The case of the Palace of the Dukes of Braganza in Guimarães (Portugal)

2015

A contemporary worldwide trend is exposing the structural elements of a building to create an articulate and complex architecture whose lines of force give robustness, stability and, at the same time, a sort of lightness and frivolity to the entire construction. However, the combination between the visual conception of architecture and the principles of statics is not new to the world of construction. Exposed structure as a design approach may be observed in many historical buildings, either public, religious or private, and in several cultural and geographical areas where exposed structures communicate power, solidity, and rigour along with an instance of economy and lightness. In this wor…

Wooden domes, vaulted and flat ceilings, partition walls in the Sicilian constructive tradition knowledge for the safeguard of architecture abd techn…

2014

The domes, vaulted and flat ceilings and also the partition walls built with wood and reeds had a particular diffusion from the XVII century, in Palermo as well as in other countries of Sicily, in many regions of Italy and in the whole Europe. The consolidated constructive tradition made them one of the most appreciated and usual systems for structural frame and for the definition of interior rooms, employed both for the monumental housebuilding and for that of minor importance, also owing to the adoption of economic materials. These wooden structures in the monumental architecture contain the rich pictorial and stucco decoration and define - together with other aspects of quality - the aul…

Photocatalytic nano-composite architectural lime mortar for degradation of urban pollutants under solar and visible (interior) light

2017

Abstract Recent advances in nano-technology and nano-additives can give enhanced properties to natural hydraulic lime (NHL), creating a multifunctional material. We have prepared a novel nanocomposite, made of a commercial mortar with 1 wt% and 5 wt% added titania nanoparticles (NPs). These TiO 2 NPs are themselves doped with 1 mol% silver, to give the material enhanced photocatalytic and antimicrobial properties. The Ag-doped TiO 2 NPs were made from a simple, costs effective, aqueous green nanosynthesis process, and the end material only contains 0.01–0.05% Ag. As this mortar is intended to both combat atmospheric pollution, and create more durable/lower maintenance building facades (plas…
