In questo lavoro di tesi viene trattato il tema dell’interoperabilità nell’ambito della gestione energetica degli edifici, nella fase post-costruzione. Inizialmente, viene spiegato chi è l’Energy Manager e qual è il suo compito all’interno di un’organizzazione, facendo anche una panoramica della normativa che ruota attorno alla sua figura. Viene spiegato cos’è il BIM (Building Information Model) e come può essere utilizzato nello svolgimento della pratica dell’energy management, oltre a come può essere integrato all’interno delle piattaforme CAFM (Computer Aided Facility Management) e CMMS (Computerized Maintenance Management System). Come terzo punto si è mostrata la situazione attuale nel mercato energetico, facendo delle considerazioni su come è mutata nel corso degli anni e per quali ragioni economiche e geo-politiche. Infine, è stato fatto un inquadramento generale su come è organizzata la gestione energetica degli edifici all’interno dell’Università di Padova, qual è l’ufficio competente che si occupa di questa disciplina e quali sono le mansioni che devono portare a compimento gli Energy Manager che fanno parte di questa organizzazione. Uno dei problemi principali individuato durante la fase di gestione energetica delle strutture, è quella della reperibilità dei dati che servono nella fase di Operation e Management (O&M): per questo motivo la ricerca di lavoro, si pone come obbiettivo quello di individuare una metodologia per archiviare documenti e informazioni da parte di tutti gli utenti che partecipano al ciclo di vita dell’opera. Per fare ciò, è stato individuato un formato file interoperabile con tutti i maggiori software di progettazione e di gestione dati, che si identifica nel formato IFC (Industry Foundation Classes), in modo che i vari professionisti possano leggere con i propri strumenti i documenti prodotti dagli altri utenti, creando un quadro informativo completo dei vari edifici sui cui si opera. In seguito all’analisi di letteratura svolta è emerso che lo standard IFC non viene sfruttato nelle sue piene potenzialità, ma viene utilizzato quasi esclusivamente come formato file, in grado di importare i modelli BIM all’interno dei software di simulazione energetica. Mentre, sono stati individuati pochissimi articoli in cui gli autori lo utilizzano come database di archiviazione di dati, utili nello svolgimento della disciplina del facility management. Dopo aver redatto una lista con i documenti e le informazioni, che l’energy manager deve gestire, è stata fatta una prima classificazione in Excel delle classi IFC verso le quali può essere indirizzato il dato; poi la referenziazione dei dati è stata messa in pratica all’interno del modello BIM, tramite l’utilizzo di Archicad e completata dalla scrittura di codici su Python, tramite le librerie di IfcOpenshell. La sfida di questa ricerca è di verificare se la piattaforma Geoweb è interoperabile con il datamodel IFC, per quanto concerne l’archiviazione dei dati utilizzati nello svolgimento della disciplina dell’energy management. Infine, sono stati commentati i risultati ottenuti evidenziando le criticità del processo sviluppato e discutendo quali potrebbero essere i possibili sviluppi futuri che la ricerca si potrebbe porre.
