GreenBIM – Fundamentals for the integration of building greening in openBIM projects

ABSTRACT: Due to urban overheating building greening systems are becoming more important. Models of greening systems will thus play an important role in future openBIM based planning processes. However, open exchange formats such as IFC do not include attributes for such systems now. To close this gap, the required attributes to describe building greening were developed by a multidisciplinary team of specialists. Necessary attributes were determined based on norms, standards and experience from pilot projects. Moreover, the
attributes were equipped with project phase information and responsibilities. The identified attributes were structured in agreement with the IFC data structure and implemented in a BIM data management platform. The comparison of the identified greening attributes with the IFC standard shows gaps in the IFC standard. It is thus important to enhance the IFC standard and the bSDD. This enhancement would bring benefits for project stakeholders in many use cases alongside an openBIM process.
