Il settore delle costruzioni è sempre più chiamato ad affrontare la sostenibilità attraverso informazioni strutturate, misurabili e verificabili. In questo contesto, il Building Information Modelling (BIM) e gli standard openBIM possono migliorare la gestione dei requisiti ambientali, sebbene la verifica della conformità si basi spesso su documentazione frammentata e controlli manuali. Questa tesi indaga l’uso dell’Information Delivery Specification (IDS) per strutturare e verificare requisiti informativi legati alla sostenibilità, derivati dai Criteri Ambientali Minimi, con riferimento ai CAM 2025. La ricerca adotta un approccio qualitativo e applicativo. Dopo aver definito il quadro teorico e normativo, criteri CAM vengono analizzati in base alla loro natura informativa, alla relazione con entità BIM e IFC e all’idoneità alla verifica tramite IDS. I requisiti sono tradotti in condizioni informative basate sul modello e testati attraverso un flusso BIM–IFC–IDS. Un modello caso studio in Revit viene arricchito con elementi, classificazioni e parametri personalizzati, esportato in formato IFC4x3 Add2, ispezionato in usBIM.browser e validato in usBIM.IDS. La libreria IDS sviluppata include specifiche a diversi livelli: spazi, proprietà di edificio, impianti tecnici, componenti dell’involucro ed elementi di solaio con strati in calcestruzzo. La validazione mostra che IDS può rilevare valori conformi, dichiarazioni non conformi e informazioni mancanti nel modello IFC. La ricerca conferma il potenziale di IDS nel supportare trasparenza, ripetibilità e tracciabilità nella gestione delle informazioni legate ai CAM. Lo studio evidenzia alcune limitazioni. IDS può verificare presenza, struttura e valore dichiarato delle informazioni, ma non può sostituire valutazioni specialistiche, calcoli, simulazioni, certificazioni di prodotto o documentazione tecnica. Deve quindi essere inteso come strumento di controllo informativo in un più ampio processo di verifica della conformità. Sviluppi futuri potranno estendere l’approccio ad altri criteri CAM, documentazione esterna, dati digitali di prodotto e protocolli di valutazione della sostenibilità, come il Protocollo ITACA.

Abstract
The construction sector is increasingly required to address sustainability through structured, measurable and verifiable information. In this context, Building Information Modelling (BIM) and openBIM standards can improve the management of environmental requirements, although compliance verification often still relies on fragmented documentation and manual checks. This thesis investigates the use of Information Delivery Specification (IDS) to structure and verify sustainability-related information requirements derived from the Minimum Environmental Criteria for buildings, with reference to CAM 2025. The research adopts a qualitative, application-oriented approach. After defining the theoretical and regulatory framework, selected CAM criteria are analysed according to their informational nature, relationship with BIM and IFC entities, and suitability for IDS-based verification. The requirements are translated into model-based information conditions and tested through a BIM–IFC–IDS workflow. A Revit case-study model is enriched with elements, classifications and custom parameters, exported in IFC4x3 Add2 format, inspected in usBIM.browser and validated in usBIM.IDS. The resulting IDS library includes specifications at different information levels: spaces, building-level properties, technical systems, envelope components and slab elements with concrete layers. Validation shows that IDS can detect compliant values, intentionally non-compliant declarations and missing information in the IFC model. The research confirms the potential of IDS to support transparency, repeatability and traceability in managing CAM-related information. The study also highlights key limitations. IDS can verify the presence, structure and declared value of information, but cannot replace specialist assessments, calculations, simulations, product certifications or technical documentation. It should therefore be understood as an information-checking tool within a broader compliance verification process.
