A seguito delle problematiche riguardanti i rifiuti in edilizia e il cambiamento climatico, oggigiorno si stanno sviluppando sempre più soluzioni che mirano al risparmio energetico negli edifici. Una delle nuove tecnologie che soddisfa questa richiesta è la facciata adattiva. Questa soluzione è infatti in grado di sfruttare la luce naturale per ottenere vantaggi dal punto di vista energetico e del comfort luminoso. Al fine di valutare le prestazioni di nuovi progetti di facciate, viene utilizzata un'ampia gamma di software di simulazione per la valutazione delle prestazioni degli edifici (Building Performance Simulation tools BPS ), in grado di condurre calcoli ambientali, termici e illuminotecnici su geometrie complesse. Questa tesi si concentra sull'identificazione degli elementi che causano differenze nei risultati di due software, IES VE e Rhinoceros con i suoi plug-in, per comprenderne le potenzialità e i limiti nell'analisi di una facciata dinamica. In particolare, è stato interessante studiare fino a che punto il primo programma riesca a coprire le ampie funzionalità del secondo, specialmente considerando i calcoli illuminotecnici. Questo lavoro è stato condotto attraverso analisi mirate e confronti critici, nello studio prima di forme semplici e poi di una facciata adattativa; per quest'ultimo caso è stato scelto un ufficio orientato a Sud-Est situato a Siviglia, in Spagna, in cui è stata applicata la facciata. Come risultato principale è stato ottenuto che per questo tipo di studio è possibile sfruttare entrambi i software, per valutare le metriche dinamiche. Quindi, nonostante le diverse potenzialità, è stato possibile eseguire le stesse categorie di analisi. Per riassumere, è conveniente dire che i due software sono compatibili poiché i valori calcolati, raramente presentano grosse discrepanze.

Abstract
As a result of the issues regarding the waste in the building field and the climate change, nowadays more and more solutions that aim to the energy saving in buildings are being developed. One of the new technologies that satisfies this demand is the adaptive façade implementation. This solution is in fact able to exploit the natural daylight to obtain advantages from the energy point of view and the daylight comfort. In order to evaluate the performances of new façades projects, a wide range of building performance simulation (BPS) tools is used, which are able of conducting environmental, thermal and daylight calculations on complex geometries. This dissertation focuses on identifying the causes that lead to differences in the results of two BPS software, IES VE and Rhinoceros with its plug-ins, to understand their potentials and limitations when analysing a kinetic façade. In particular, it was interesting to study to what extent the first program manages to cover the broad functionalities of the second when considering daylight dynamic calculations. This work is conducted through target analyses and critical comparisons, in the study of basic shapes first, and of an adaptive façade afterwards; for this latter case it was chosen a South-East oriented office room located in Sevilla, Spain, in which the façade was applied. As main result it has been obtained that for this typology of study it is possible to exploit both software, in order to evaluate the dynamic metrics of daylight. In fact, despite the different potentials, it was possible to perform the same categories of analyses. To sum up, it is convenient to say that the two software are compatible since the values calculated rarely present large discrepancies.| File | Dimensione | Formato | |
