La Camera dello Scirocco di Villa Naselli di Gela a Palermo
2022
L'articolo tratta il complesso della Camera (o Stanza) dello Scirocco di Villa Naselli Ambleri a Palermo, una delle poche superstiti e meglio conservate dell'agro palermitano. Tipologicamente, una Stanza dello Scirocco è una struttura sotterranea artificiale, costruita in prossimità di una sorgente d'acqua per riprodurre le piacevoli condizioni di frescura che si possono avvertire in una caverna naturale. I manoscritti e i documenti d'archivio riportano che, in questi luoghi, i nobili amavano trascorrere del tempo in compagnia di parenti ed amici per sfuggire alla calura estiva, banchettando e rinfrescandosi nell'acqua fresca. Dopo aver inquadrato la borgata della Grazia (oggi Villagrazia),…
Aria, acqua, terra e fuoco. Dalle modernità dell’Architettura all’avvenire del progetto nella transizione ecologica ed energetica
2022
Un fronte di ricerca relativamente nuovo è oggi impegnato nella costruzione di un’interpretazione plurale delle Modernità dell’architettura. Identità locali, pertinenze geoclimatiche, politiche energetiche, conferiscono così sfumature inedite al periodo compreso fra gli anni Venti del Novecento e il Team X, che resta fra i riferimenti principali per la fondazione del sapere progettuale nell’Università italiana. Nella coralità di intersezioni che questo approccio disvela, si consolida un nucleo di grande potenzialità formativa, che pone in modo chiaro la piena pertinenza disciplinare del rapporto fra la Composizione Architettonica e Urbana e i fattori climatici e ambientali. Riposizionato in…
Soluzioni basate sulla natura per le città portuali. L’approccio “Building with nature” e i limiti di trasferibilità nel contesto italiano
2022
Achieving sustainable development goals in port cities is an increasingly challenging task as the trend is toward their expansion for global competition, thus increasing their impacts on soil, atmosphere, water, and marine and terrestrial ecosystems. The present contribution proposes to explore the Building with Nature approach developed by EcoShape and Deltares in the Dutch context through the comparison of case studies and to highlight some critical issues in its transferability to the Italian context.
Simplified thermal analysis of naturally ventilated dwellings
1991
Abstract A simplified comprehensive methodology for thermal comfort prediction in a naturally crossventilated room is described. The methodology mainly consists of the following three steps: • - analysis of the dynamic thermal behaviour of the given room, by means of the admittance procedure; • - evaluation of the air flows rates and their velocities in the room, by means of a new simplified method; • - thermal comfort prediction by means of the Fanger's theory. The results obtained appear satisfactory and the simplified methodology makes itself a useful tool for the identification of appropriate choices at the early stages of the design process, regarding naturally ventilated buildings. Th…
Energy Use in the Building Sector and Climate Change: Modeling, Developments, and Future Trends
2020
Climate change is going to have significant impacts among a wide range of areas and domains, including the building sector, characterized by constructions which may not be designed to be resilient to the evolutions in the warming climate that will occur in the next decades. The chapter investigates methodologies and approaches connected to the assessment of the effects of climate change to the energy use within the building sector. Methodologies are compared and the most relevant future trends expected are traced for the current century.

Effect of Climate Change on Building Performance: the Role of Ventilative Cooling
2017
Climate Change represents a priority, due to the large variety of implications and importance that it has reached throughout the last decades. In an effort to address this global and local challenge and in order to restrict temperature rise to 2 °C over the next century, it will need to address this topic from several angles, as confirmed by the last COP meetings in Paris and in Marrakech. In this context, the paper presents the modelling and assessment of ventilative cooling applicability in the future of the Mediteranean area under the effects of climate change. Results show that natural ventilation will continue to be of paramount importance in the Mediterranean climate but its highest e…
Comparison between the performances of daylight linked control system at two different latitudes
2019
The aim of this work is to compare the performance of a daylight-linked control system installed and tested in two different case studies by means of a set of indices. The two case studies are characterized by different geometry, location and windows orientation. The first one is located at the ENEA premises in Lampedusa (IT, 35° 30' N); the second one is located in Palermo (IT, 38°6' N) on the third floor of the building 9 of the Department of Engineering if the University of Palermo. In both cases, the indices were calculated by using the same daylight-linked control system and the same end-use (office). The results were reported and analysed in order to demonstrate as the performances of…
An integrated building energy simulation early—Design tool for future heating and cooling demand assessment
2022
Climate change and its effects are becoming clear on a global scale either from the perspective of global warming and the increase in the rate of occurrence of weather events of extreme magnitude. This has impacts also for sure on the standard building performance analysis approach, since the buildings designed today are supposed to withstand for the following decades climate impacts that may be different than those they were designed for. The paper proposes a simple, easy to use and freely available building simulation utility which performs morphing of existing weather data files and, by connecting to the Energy Plus simulation routine, allows to perform future climate building simulation…
