L'applicazione della rete metallica stirata alle facciate degli edifici è diventata molto comune, a causa dei suoi vantaggi nelle prestazioni dell'edificio; così come la sua produzione e l'efficienza dei costi. Poiché una delle aree di utilizzo più significative è il rivestimento esterno, ne vengono evidenziate le proprietà ombreggianti. Le sue proprietà geometriche, quelle cruciali sono la dimensione dei fori, lo spessore e l'angolo delle strisce, influenzano il comfort della luce diurna all'interno dell'edificio e possono essere variate in un'ampia gamma entro i limiti di produzione. Ciò provoca un forte aumento del mercato dei materiali da costruzione, nonché l'interesse nel campo dell'architettura sostenibile. L'obiettivo di questa ricerca è quello di sfruttare la rete metallica stirata come dispositivo ombreggiante nei suoi parametri geometrici; proporre un sistema in cui questi input si adattano in base all'orientamento della superficie vetrata e alle proprietà climatiche della sua posizione. L'adeguamento sarà mirato al raggiungimento di condizioni di comfort dei livelli di illuminamento interno proponendo l'utilizzo della lastra a diverse tipologie di superfici. La metodologia è ulteriormente dimostrata dall'operazione di ottimizzazione su edifici caso studio con diverse proposte per la forma della superficie, esaltando il valore dell'autonomia spaziale diurna di uno spazio sottoposto.

Abstract
The application of the expanded metal mesh to the building façades has become very common, because of its advantages in building performance; as well as its production and cost-efficiency. As one of the most significant areas of usage being the exterior cladding, the shading properties of it are highlighted. The geometrical properties of it, the crucial ones being the size of the holes, thickness, and the angle of the strips, are affecting the daylight comfort inside the building and can be varied in a wide range within the production limitations. This causes a compelling increase in the construction materials’ market, as well as the interest in the field of sustainable architecture. The goal of this research is to exploit the expanded metal mesh as a shading device within its geometrical parameters; proposing a system where these inputs adapt according to the orientation of the glazed surface and the climate properties of its location. The adaptation will be focused on achieving comfort conditions of illuminance levels inside while proposing the implementation of the sheet to various typologies of surfaces. The methodology is further demonstrated by the optimization operation on case study buildings and three critical surface typologies to confirm and improve the efficiency of the shading system. Satisfactory improvements on the daylight comfort, measured by Customized Spatial Daylight Autonomy, have been obtained by exploiting the geometrical parameters of the expanded metal mesh. The advantages of it is offered within variety of design solutions to the field of sustainable architecture.File | Dimensione | Formato | |
