The present thesis work aims at analyzing the dynamic simulation of the entire building-plant system of Palazzo Mercanti, a historical building located in Piazza Cordusio in Milan. The dynamic simulation has had a remarkable development only in the last few years thanks also to the increase of the computing power: therefore it is a current theme, more and more in use, and in the future this instrument probably will become mandatory for the analysis of the building-plant system to purposes of reducing primary energy consumption. The first objective is to verify that the plant serving the building is able to maintain the internal thermohygrometric conditions throughout the year through the analysis of 3 rooms considered critical for maintaining comfort, exploiting dynamic simulation. The study also involved the analysis of the coverage of the vertical glass connective: two different types of glass were analyzed to show that the design solution chosen is the only one able to maintain the comfort conditions inside the room. The other result concerned LEED certification and the number of points obtainable for the "Optimize Energy Performance" credit based on the performance increase of the Proposed Building compared to the Baseline Building, in the "Energy and Atmosphere" evaluation area and after have fulfilled the "Minimum Energy Performance" prerequisite. Finally, some significant results were reported regarding the operation of the HVAC system. This analysis was articulated according to a first introductory part to the building which is followed by a section dedicated to in-depth study of the normative and laws in force and then to the descriptive chapter of the HVAC system and the introductory chapter to the LEED certification. Then the dynamic simulation was presented and the program used: IES Virtual Environment. Finally, there is the chapter dedicated to the analysis of the results and the conclusions with suggestions for future improvements and implementations of the model.
Il presente lavoro di tesi ha come obiettivo l’analisi della simulazione dinamica del sistema edificio-impianto di Palazzo Mercanti, un edificio storico situato in Piazza Cordusio a Milano. La simulazione dinamica ha avuto un notevole sviluppo soltanto negli ultimi anni grazie anche all'incremento della potenza di calcolo disponibile: quindi è un tema attuale, sempre più in uso, e quasi certamente in futuro questo strumento diverrà obbligatorio per l’analisi del sistema edificio-impianto. Il primo obiettivo è stato verificare che l’impianto a servizio dell’edificio sia in grado di mantenere le condizioni termoigrometriche interne per tutto l’anno attraverso l’analisi di 3 locali ritenuti critici per il mantenimento del comfort, sfruttando proprio la simulazione dinamica. Lo studio ha coinvolto anche l’analisi della copertura del connettivo verticale vetrato: sono state analizzate due differenti tipologie di vetro per dimostrare che la soluzione progettuale scelta è l’unica in grado di mantenere le condizioni di comfort all'interno del locale. L’altro risultato ottenuto ha riguardato la certificazione LEED ed il numero di punti ottenibili per il credito “Optimize Energy Performance” sulla base dell’incremento di performance del Proposed Building rispetto al Baseline Building, nell'area di valutazione “Energy and Atmosphere” e dopo aver soddisfatto il prerequisito “Minimum Energy Performance”. Infine si sono riportati alcuni risultati significativi riguardanti il funzionamento dell’impianto HVAC. Tale analisi si è articolata secondo una prima parte introduttiva all'edificio cui trova seguito una sezione dedicata all'approfondimento delle normative vigenti per poi passare al capitolo descrittivo dell’impianto HVAC e quello introduttivo alla certificazione LEED. Quindi si è presentata la simulazione dinamica ed il programma utilizzato: IES Virtual Environment. Infine trova ampio spazio il capitolo dedicato all'analisi dei risultati e le conclusioni con i suggerimenti per futuri miglioramenti ed implementazioni del modello.

Abstract
The present thesis work aims at analyzing the dynamic simulation of the entire building-plant system of Palazzo Mercanti, a historical building located in Piazza Cordusio in Milan. The dynamic simulation has had a remarkable development only in the last few years thanks also to the increase of the computing power: therefore it is a current theme, more and more in use, and in the future this instrument probably will become mandatory for the analysis of the building-plant system to purposes of reducing primary energy consumption. The first objective is to verify that the plant serving the building is able to maintain the internal thermohygrometric conditions throughout the year through the analysis of 3 rooms considered critical for maintaining comfort, exploiting dynamic simulation. The study also involved the analysis of the coverage of the vertical glass connective: two different types of glass were analyzed to show that the design solution chosen is the only one able to maintain the comfort conditions inside the room. The other result concerned LEED certification and the number of points obtainable for the "Optimize Energy Performance" credit based on the performance increase of the Proposed Building compared to the Baseline Building, in the "Energy and Atmosphere" evaluation area and after have fulfilled the "Minimum Energy Performance" prerequisite.
