This thesis discusses the theme of the energy audit of the terminal 1 of Roma Fiumicino airport and it is mainly focused on its mechanical systems; this work, in fact, is the natural continuation of a previous one in which the attention was principally addressed to the envelope. The thesis was developed in four main phases that are briefly explained here after. The theme was approached from different sides. First, the procedure of the energy audit has been defined and then a research in literature was performed in order to find some previous experiences about energy audits of airports. In the end, a further analysis was developed about the state of art of airports and in particular of their technological systems and their way of exploiting renewable energies. Switching then to the specific subject of analysis, the work followed with the study of, by a side, the characteristics of the building system and, by the other, of all the analysis developed during the previous thesis, assumed as a starting point. The energy audit of the terminal 1 of Roma Fiumicino started then with a detailed characterization on an area and of its air-handling unit, by the construction of a numerical dynamic model and its calibration, activity possible thanks to monitoring data. Energy consumptions and load profiled of these area obtained by the model, were parametrically extended to the whole building in order to have a basis for the following development of energy saving opportunities. In the last phase, the technical feasibility, the energy benefit and the economical convenience of a set of interventions on the technological systems were evaluated. Different kinds of energy saving opportunities were proposed, from the simple adoption of an intermittent regime, to the replacement of the generation system, passing by interventions on the AHU with the adoption of a DEC system. The possibility of exploitation of renewable energies was deeply taken into account, and in particular of sources like the sun, the aquifer and the aerothermal heat.
Il presente elaborato affronta il tema della diagnosi energetica del terminal 1 dell'aeroporto di Roma Fiumicino e si concentra il particolar modo sul sistema impiantistico; il lavoro si configura infatti come naturale prosecuzione di una tesi precedente nella quale è stato invece approfondito il tema dell'involucro. Il presente lavoro è stato sviluppato in quattro fasi principali, di seguito brevemente illustrate. L'approccio al tema trattato è avvenuto su più fronti. Dapprima è stata delineata la procedura della diagnosi energetica, poi si è proseguito cercando in letteratura esperienze in ambito aeroportuale, infine è stato effettuato un approfondimento circa lo stato dell'arte degli aeroporti per quanto concerne i sistemi impiantistici ed in particolare lo sfruttamento delle energie rinnovabili. Passando quindi al terminal oggetto di analisi, si è proseguito studiando, da un lato, le caratteristiche del sistema edificio-impianto, e dall'altro, tutte le analisi già svolte durante il lavoro precedente, assunte in questa sede come punto di partenza. La diagnosi vera e propria ha quindi preso avvio con la caratterizzazione dettagliata di un'area del terminal e dell'unità di trattamento aria al suo servizio, attraverso la costruzione di un modello numerico in regime dinamico e la sua calibrazione effettuata grazie a dati di monitoraggio. Quanto ottenuto a livello di consumi e profilo di carico è stato poi esteso parametricamente all'intero edificio in modo da avere una base per il successivo sviluppo delle opportunità di risparmio energetico. Infine, quindi, è stata valutata la fattibilità tecnica, il beneficio energetico e la convenienza economica di interventi impiantistici che spaziano dalla semplice adozione di un regime di funzionamento di tipo intermittente, fino ad arrivare alla sostituzione dell'attuale sistema di generazione, passando da interventi sulle UTA che contemplino l'adozione di sistemi DEC. Il tutto con una particolare attenzione allo sfruttamento delle fonti rinnovabili, quali il sole, la falda ed il calore aerotermico.

Abstract
This thesis discusses the theme of the energy audit of the terminal 1 of Roma Fiumicino airport and it is mainly focused on its mechanical systems; this work, in fact, is the natural continuation of a previous one in which the attention was principally addressed to the envelope. The thesis was developed in four main phases that are briefly explained here after. The theme was approached from different sides. First, the procedure of the energy audit has been defined and then a research in literature was performed in order to find some previous experiences about energy audits of airports. In the end, a further analysis was developed about the state of art of airports and in particular of their technological systems and their way of exploiting renewable energies. Switching then to the specific subject of analysis, the work followed with the study of, by a side, the characteristics of the building system and, by the other, of all the analysis developed during the previous thesis, assumed as a starting point. The energy audit of the terminal 1 of Roma Fiumicino started then with a detailed characterization on an area and of its air-handling unit, by the construction of a numerical dynamic model and its calibration, activity possible thanks to monitoring data. Energy consumptions and load profiled of these area obtained by the model, were parametrically extended to the whole building in order to have a basis for the following development of energy saving opportunities. In the last phase, the technical feasibility, the energy benefit and the economical convenience of a set of interventions on the technological systems were evaluated. Different kinds of energy saving opportunities were proposed, from the simple adoption of an intermittent regime, to the replacement of the generation system, passing by interventions on the AHU with the adoption of a DEC system. The possibility of exploitation of renewable energies was deeply taken into account, and in particular of sources like the sun, the aquifer and the aerothermal heat.File | Dimensione | Formato | |
