Digital information and data flow management for building envelope solutions: the MEZeroE BIM dataset tool as an Open Innovation Service

Data inconsistency and limited interoperability among various stakeholders compromise data uniformity and hinder digitalization across all stages of the construction life cycle, thereby inhibiting effective collaboration in the development of innovative envelope construction solutions. To address these challenges, the MEZeroE project developed a novel standardized Building Information Modeling (BIM) dataset tool that enables stakeholders to access consistent, high-quality and application-specific data in a unified digital environment. This study presents the development and implementation of the MEZeroE standardized digital dataset tool, which introduces a structured and interoperable framework for data flow management specifically tailored to innovative building envelope solutions. By combining a systematic literature review with a Grounded Theory approach, the study identifies critical gaps in current practices and defines nine Construction Segments and fourteen envelope parameter categories, which represent a new standardized data structure for envelope solutions. The tool is integrated into the MEZeroE Virtual Marketplace, providing a practical digital infrastructure that supports BIM object creation, facilitates Digital Product Passport compliance, and enables real-time collaboration among designers, manufacturers, and other stakeholders. This integration enhances decision-making processes and accelerates the adoption and deployment of innovative building envelope technologies in real-world construction projects.
