The relavance of indoor comfort in the process of prisoners’ rehabilitation: a case study
2016
The history of prisons is full of contradictions in every historical period and the evolution of prison buildings expresses many faces in the history of each country. The concept of punishment imposed on the offender has undergone several changes over the centuries, related to culture, politics, and to the evolution of the human thought. For centuries, tiny closed spaces have been adapted for the offenders' detention, without ever thinking to create an ad hoc functional distribution of spaces. The issue of the design of prisons has often been a reason of debate, and it is still an open field of discussion. From a legal point of view, in recent years there has been a rethinking of the proble…
Integrated analysis of performances of facades for indoor comfort purposes
2002
Some guidelines for a method able to evaluate different physical characteristics of building facades, equipped with glazed surfaces, and of indoor environments in order to attain indoor comfort conditions are proposed. New graphs are introduced, showing at the same time the behaviours of several technical-physical parameters of walls, in order to allow comparative analysis of different design configurations in terms of acoustics, lighting and heat transfer properties. Similar graphs are also constructed with reference to parameters characteristic of indoor environment, in order to allow synthetic analysis of comfort conditions. The method would represent a contribution toward the definition…
I borghi interni in Sicilia: recupero dell’identità e strategie di valorizzazione
2021
La promozione di studi e ricerche volti al recupero e alla valorizzazione delle aree interne marginali e dei centri minori, indirizzati a supportare Regioni, Comuni e cittadinanza locale, estremamente utili all’individuazione di soluzioni più opportune per lo sviluppo sostenibile e la valorizzazione di luoghi e architetture, ha suggerito la ricerca che in questo saggio si vuole illustrare, rivolta a investigare – in prima battuta e in termini generali – i caratteri identitari dell’area montana interna siciliana delle “Madonie” e nel dettaglio, invece, il borgo “Pusterna” del comune di Petralia Sottana. Si verificheranno, per quest’ultimo, i livelli di comfort indoor raggiungibili nell’ambit…
Evaluation of the indoor comfort of the Arabic-Norman architecture for its valorization
2018
Nel 2015 il percorso arabo normanno di Palermo, Cefalù e Monreale è stato riconosciuto patrimonio dell’Umanità. Tra i monumenti del percorso la Zisa costituisce un esempio straordinario di tipologia edilizia con caratteristiche tecnologiche ed ambientali uniche perché, originariamente, era caratterizzato dall'integrazione di alcuni sistemi passivi per il miglioramento del comfort ambientale interno. Fu costruito nel 1160 da artigiani arabi. Era caratterizzato dalla presenza di un sistema di raffreddamento evaporativo e ventilazione naturale che garantiva livelli di comfort che potevano essere soddisfacenti anche ai giorni nostri. La ricerca propone i risultati ottenuti attraverso l’applicaz…
Evaluation of the Thermodynamic Performance of the Traditional Passive Systems
2011
The need to reduce urban consumption of energy in the buildings, one of the major energy waster resulting in emission of CO2, is pushing research in the field of building design to the appreciation of passive air-conditioning systems that can be integrated with conventional systems and determine, therefore, the so-called hybrid systems. Historically this passive systems were developed in the Mediterranean and in the Middle East area. Actually the research activity has been focused on this problem, through an approach that involves the application of design strategies and the development of computational tools and control systems. The synergy between current scientific knowledge, advanced ma…
Liberty winter gardens in Palermo: contamination from solar design
2020
At the end of the 19th century, the city of Palermo boasted a tradition of steel elements that could include the most beautiful railings and light steel structures of the time. The paper shows how the technological, formal and spatial aspects of the metallic construction was derived by the application of Central Europe areas examples to the local reality, providing notions on designs, experimentations and originalities. Canopies, verandas, winter gardens and orangeries are architectural elements in iron and glass that represent an added value for the building, they improve the life quality of the people who live there. In particular, in the Liberty architecture these elements took shape thr…

ANALYSIS OF THE TRADITIONAL PASSIVE SYSTEMS PERFORMANCE THROUGH THE APPLICATION OF CFD SOFTWARE
2012
The need to reduce energy consumption is pushing the building design research to the evaluation of passive conditioning systems, since urban buildings are one of the major energy dissipater resulting in emission of CO2. This approach is not modern, but it is historically rooted in the architectural culture of the Mediterranean area and in the Middle East. The passive systems have ancient origins: they were developed to mitigate the summer heat and the winter cold. To understand the reasons that led to the development of passive systems, it should be remembered that about One-Fifth of the emerged planet surface and One-Third of the world's population live in conditions of warm-dry or hot-hum…
Indoor air quality in schools of a highly polluted south Mediterranean area
2019
This study aimed at surveying lower secondary schools in southern Italy, in a highly polluted area. A community close to an industrial area and three villages in rural areas was investigated. Indoor temperature, relative humidity (RH), gaseous pollutants (CO 2 and NO 2 ), selected biological pollutants in indoor dust, and the indoor/outdoor mass concentration and elemental composition of PM 2.5 were ascertained. Temperature and RH were within, or close to, the comfort range, while CO 2 frequently exceeded the threshold of 1000 ppm, indicating inadequate air exchange rate. In all the classrooms, median NO 2 levels were above the WHO threshold value. Dermatophagoides p. allergen concentration…
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
