This study investigates how to effectively integrate lighting design and color material and finishes (CMF) design within Building Information Modeling (BIM) workflows, with specific attention to real-time visualization and the digital project environment.

Questo studio indaga come integrare efficacemente il design dell'illuminazione e il design dei materiali e delle finiture (CMF) all'interno dei flussi di lavoro del Building Information Modeling (BIM), con particolare attenzione alla visualizzazione in tempo reale e all'ambiente di progetto digitale. L'obiettivo principale è fornire ai progettisti e ai team interdisciplinari metodologie robuste e quadri pratici che migliorino l'integrazione e l'affidabilità dei dati di illuminazione e dei materiali nei processi abilitati BIM. La metodologia adottata nello studio è mista: revisione della letteratura, indagini empiriche, interviste con esperti del settore e verifica di casi studio sono combinati per fornire una panoramica solida e completa dei flussi di lavoro BIM. La ricerca ha evidenziato alcune aree problematiche chiave: interoperabilità, mancanza di o insufficiente standardizzazione dei dati, e tracciabilità dei dati non sempre presente. Inoltre, la rappresentazione in tempo reale della luce e dei materiali evidenzia limitazioni e approssimazioni rispetto alla realtà, potenzialmente compromettendo la validità di alcune scelte progettuali. La discussione include un esame approfondito delle informazioni richieste dai fornitori—come i dati spettrali, i file IES e i parametri di temperatura di colore correlati—e valuta se gli attuali standard siano sufficienti per una simulazione digitale accurata e per la presa di decisioni. La ricerca evidenzia quanto sia cruciale promuovere processi trasparenti, standard aperti per la gestione dei dati e una rigorosa validazione. Migliorare l'affidabilità e la qualità dei flussi di lavoro – sia nel BIM che nelle visualizzazioni in tempo reale – dipende da aggiornamenti continui delle metodologie, dalla genuina collaborazione tra diverse competenze e dalla costante crescita degli strumenti digitali disponibili. Solo in questo modo è possibile orientare il processo verso risultati veramente robusti, replicabili e scientificamente affidabili. Infine, la ricerca sviluppa flussi di lavoro e best practices, proponendo kit di strumenti utili per i designer. L'importanza dello sviluppo metodologico proposto in un contesto multidisciplinare è centrale per garantire l'affidabilità e la qualità dell'integrazione del design dell'illuminazione e del CMF nel BIM, insieme a una visualizzazione in tempo reale del progetto.

Abstract
This study investigates how to effectively integrate lighting design and color material and finishes (CMF) design within Building Information Modeling (BIM) workflows, with specific attention to real-time visualization and the digital project environment. The main objective is to provide designers and interdisciplinary teams with robust methodologies and practical frameworks that enhance the integration and reliability of lighting and material data in BIM-enabled processes. The methodology adopted in the study is mixed: literature review, empirical investigations, interviews with industry experts, and case study verification are combined to provide a solid and comprehensive overview of BIM workflows. The research highlighted some key problem areas: interoperability, lack of or insufficient data standardization, and data traceability not always present. Furthermore, the real-time representation of light and materials highlights limitations and approximations compared to reality, potentially compromising the validity of certain design choices. The discussion includes a thorough examination of the information required from suppliers—such as spectral data, IES files, and correlated color temperature parameters—and evaluates whether current standards are sufficient for accurate digital simulation and decision-making. The research highlights how it is crucial to promote transparent processes, open standards for data management, and rigorous validation. Improving the reliability and quality of workflows – both in BIM and real-time visualizations – depends on continuous updates to methodologies, genuine collaboration between different skill sets, and the constant growth of available digital tools. Only in this way is it possible to move the process toward truly robust, replicable, and scientifically reliable results. Finally, the research develops workflows and best practices, proposing useful toolkits for designers.
