Thermo-hygrometric comfort in hospital rooms conditioned by means of a primary air system and ceiling radiant panels

2008

In this work the first results of experimental research are described, which began in the 2006 summer season and is still underway, on the performance of a primary air system integrated with radiant ceiling panels that runs in the hospital rooms in the maternity ward of the Maggiore Hospital of Bologna. The choice of this kind of environment is based the fact that there is more and more attention toward literature on comfort standards that must be guaranteed in the hospital environment, due to the presence of typically weak users, both from the clinical and psychological point of view. The performance of the air conditioning system is taken into account in relation to the conditions of comf…

Women e-participation: glass ceiling decrease?

2012

This paper aims to review useful theoretical frame work able to encapsulate new frontiers of research on women political participation. In particular based on the feminist dichotomy of public and private sphere it investigates how Internet can enrol women in solving glass ceiling in political activism and participation considering its grassroots networked nature.

Investigation on a low environmental impact solvent mixture applied to a wooden painted slab

2016

Cleaning is one of the most complex and delicate step in a restoration project, often due to the manufacturing techniques of the artifacts and their advanced state of decay. Eco-friendly solvents can permit to execute the cleaning operations with a reduced health impact for the restorers and for the environment. In this work, the performance of the 1,3- dioxolane/methylal (DIOX-MET) solvent mixture is evaluated over a wooden painted slab that had been covered with a thin layer of a protective varnish, probably during a previous conservation work performed in the Sixties. Removal of this varnish has been considered on behalf of its yellowing degradation process, which caused chromatic change…

Fashion versus perception: the impact of surface lightness on the perceived dimensions of interior space.

2011

Objectives: We compare expert opinion with perceptual judgment regarding the influence of color on the perceived height and width of interior rooms. Background: We hypothesize that contrary to popular belief, ceiling and wall lightness have additive effects on perceived height, whereas the lightness contrast between these surfaces is less important. We assessed the intuitions of architectural experts as to which surface colors maximize apparent height and compared these intuitions with psychophysical height and width estimates for rooms differing in ceiling, floor, and wall lightness. Method: Experiment 1 was a survey of architectural experts and nonexperts. Experiments 2 and 3 presented v…

THE PAINTED CEILING OF THE NAVE OF THE CAPPELLA PALATINA IN PALERMO: AN ESSAY ON ITS GEOMETRIC AND CONSTRUCTIVE FEATURES

2010

Il testo illustra gli esiti di una ricerca sulle matrici geometriche e costruttive del soffitto il legno che copre la navata centrale della Cappella Palatina di Palermo. L’opera, già oggetto di approfonditi studi relativi ai temi iconografici delle pitture che la decorano, viene indagata tramite un accurato rilievo condotto con tecniche laser scanning al fine di risalire alle matrici geometriche del progetto; tale indagine viene condotta tenendo in adeguata considerazione la struttura tridimensionale del manufatto, basata sulla tecnica dei muqarnas. Al termine dello studio viene definita una ipotesi che evidenzia una stretta correlazione fra il tracciato regolatore che ne definisce l’impian…

Green Roofs as Effective Tools for Improving the Indoor Comfort Levels of Buildings—An Application to a Case Study in Sicily

2020

In the line of pursuing better energy efficiency in human activities that would result in a more sustainable utilization of resources, the building sector plays a relevant role, being responsible for almost 40% of both energy consumption and the release of pollutant substances in the atmosphere. For this purpose, techniques aimed at improving the energy performances of buildings&rsquo

An Original Approach to Active Climate Control Based on Equilibrium Moisture Content (EMC) as Set Point in a Middle-Age Building in Palermo, Italy

2019

In the frame of a more sustainable approach to climate control, a long term strategy has been developed and is under advanced phase of implementation by technical staff of the University of Palermo in an important building, Palazzo Steri, owned by the University. The monumental room under climate control, the Sala dei Baroni (also known as Sala Magna), has a precious wooden ceiling where the previously loadbearing elements are covered with wooden painted panels. Many of them, painted in the fourteenth c, underwent important restorations in the past due to climate related damage (cracks, warpings, paint layer delamination) and biological infestations. The room is currently undergoing an impo…

Un monte in cinque colline. La figurazione araldica del soffitto della Sala Magna chiaromontana ne La Cartagine Siciliana di Agostino Inveges e nel m…

2020

Il saggio affronta la componente araldica nella decorazione del soffitto dipinto della Sala Magna dello Steri di Palermo, raffrontando gli stemmi ancora esistenti con quelli descritti in due autorevoli fonti scritte secentesche. La seconda di queste, un manoscritto finora anonimo, viene adesso assegnata a Vincenzo Auria e datata ante 1668. The essay deals with the heraldic component in the decoration of the painted ceiling of the Sala Magna of the Steri in Palermo, comparing the still existing coats of arms with those described in two important 17th century written sources. The second of these, a manuscript until now anonymous, is now assigned to Vincenzo Auria and dated before 1668.

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…
