The present work is part of the broad research theme on the design of the components of the building vertical closures for large buildings. Between the different types of building vertical closures, in the present work the curtain wall system, whose performance depends on design choices and on quality of the workmanship in the building site, is taken into account. Among the curtain wall systems, the most efficient is the unitized system which allows in-house component assembly and the related quality controls, reduction of costs and installation time and elimination of works carried out from outside the building. This research aims to identify a construction system com-bining the high quality typical of unitized façade units with the wide design freedom request to the envelope of large buildings, while meet-ing its requirements of energy efficiency, acoustic insulation, fire re-sistance, resistance to weather agents and low maintenance. To this end, in this paper the design of a high-rise building to be constructed in the United Arab Emirates is taken into account where, due to the specificity of its geometry, different types of unitized façade are used.
Il presente lavoro si inserisce nell’ampia tematica di ricerca sulla pro-gettazione dei componenti edilizi delle chiusure verticali per edifici di grandi dimensioni. Tra le diverse tipologie di chiusure verticali, viene presa in considerazione la facciata continua le cui prestazioni dipendo-no dalle scelte progettuali e dalla qualità delle lavorazioni in cantiere. Tra i sistemi per la realizzazione delle facciate continue, particolarmente efficiente è la tecnica a cellula prefabbricata che consente l’assemblaggio dei componenti in officina e i relativi controlli di quali-tà, la riduzione dei costi e dei tempi di installazione e l'eliminazione del-le lavorazioni eseguite dall'esterno dell’edificio. La ricerca mira a indi-viduare un sistema costruttivo che coniughi l’elevata qualità tipica degli elementi di facciata a cellula prefabbricata con l’ampia libertà di design richiesta all’involucro degli edifici di grandi dimensioni, soddisfacendo al contempo i requisiti energetici, di isolamento acustico, di resistenza al fuoco, di tenuta agli agenti atmosferici e di ridotta manutenzione. A tal fine, nel presente lavoro viene preso in considerazione il progetto di un grattacielo da realizzare negli Emirati Arabi Uniti, che per la sua specificità geometrica utilizza diverse tipologie di facciate a cellula.

Abstract
The present work is part of the broad research theme on the design of the components of the building vertical closures for large buildings. Between the different types of building vertical closures, in the present work the curtain wall system, whose performance depends on design choices and on quality of the workmanship in the building site, is taken into account. Among the curtain wall systems, the most efficient is the unitized system which allows in-house component assembly and the related quality controls, reduction of costs and installation time and elimination of works carried out from outside the building. This research aims to identify a construction system com-bining the high quality typical of unitized façade units with the wide design freedom request to the envelope of large buildings, while meet-ing its requirements of energy efficiency, acoustic insulation, fire re-sistance, resistance to weather agents and low maintenance. To this end, in this paper the design of a high-rise building to be constructed in the United Arab Emirates is taken into account where, due to the specificity of its geometry, different types of unitized façade are used.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
