In Europa, gli edifici sono responsabili del 40% dell’energia consumata totale, con le rispettive emissioni di CO2 fissate al 38%. Questa situazione porta all’opportunità di ridurre la domanda di energia e a soddisfare le politiche di contenimento dei consumi in Europa, poiché oltre l'80% degli edifici effettivi sarà ancora in uso nel 2050. È in questo momento che nasce il progetto BI-SMART. Lo sviluppo di tecnologie per la riqualificazione energetica degli edifici e l'attuazione del BIM nella progettazione e realizzazione dei progetti costituisce un obiettivo principale a livello europeo. Il progetto BI-SMART sviluppa strumenti e processi volti a ottimizzare l'implementazione del BIM nel contesto della riqualificazione energetica, in particolare, con l'integrazione di strumenti BIM con simulazione dinamica avvicinando le società di ingegneria e automazione. I modelli costruiti, sia statici che dinamici, costituiscono un patrimonio per l'utente e per le aziende della filiera in quanto facilitano la proposta e la realizzazione di eventuali ulteriori miglioramenti futuri come l'introduzione di nuove tecnologie e la manutenzione degli impianti e dell'edificio. L’attività di manutenzione può essere migliorata attraverso un'efficace identificazione di malfunzionamenti e guasti e un monitoraggio continuo delle prestazioni con tecniche basate su modelli. All'interno di questo progetto, tre aziende e il DAISY lab lavorano insieme, ognuna con un simulatore di energia diverso per progettare l’integrazione tra BIM e simulatori. Ognuno riporta i propri risultati permettendo un confronto degli strumenti e delle metodologie utilizzati. Il lavoro contenuto in questa tesi riflette la progettazione, la preparazione, la simulazione e l'analisi con un simulatore di energia dinamico chiamato EnergyPlus di un edificio modellato virtualmente con un software BIM (Autodesk Revit). I file di input sono stati preparati seguendo tutti i requisiti di EnergyPlus e permettono di effettuare un'analisi energetica completa. Viene presentato infine un confronto dei risultati ottenuti con il software utilizzato dalle altre società.

Abstract
In Europe, buildings are responsible for the consumption of 40% of energy, with CO2 emissions at 38% of the estimated total. This situation leads to the opportunity of reducing the demand for energy as well to accomplish the consumption containment policies in Europe since over the 80% of the actual buildings will still be in use in 2050. It’s at this moment where the project BI-SMART is born. The development of technologies for energy-focused improvements of buildings and the implementation of BIM during the development and execution of the projects constitutes a main objective at European level. The BI-SMART project develops tools and processes aimed at optimizing the implementation of BIM in the context of energy requalification, in particular, with the integration of BIM tools with dynamic simulation brings plant engineering and automation companies closer together. The built models, both static and dynamic, constitute a patrimony for the user and for the companies of the supply chain. They make requalification proposals easier and help the realization of any other future improvements, such as the introduction of new technologies and new maintenance activities. Maintenance of plants and buildings can be improved by an effective identification of malfunctions and failures and a continuous monitoring of performance with model-based techniques. Inside this project three companies and the DAISY lab worked together, each one with a different energy simulator in order to design the implementation between BIM and the simulation. Then each one reports the results obtained leading to a comparison between tools and methodologies. The work captured in this thesis reflects the design, preparation, simulation and analysis with a dynamic energy simulator called EnergyPlus of a building virtually done with a BIM-software (Autodesk Revit). The input files have been prepared in order to be able to simulate an energy analysis satisfying all the requirements of EnergyPlus. It also contains the comparison of the results obtained with the software used by the other companies.| File | Dimensione | Formato | |
