Green BIM 2. Green Information Modelling and Operation: Transformation of the Green Sector through digitalisation

Starting point / motivation

The green industry has experienced an upswing in recent years - not least because of the climate and energy crisis. Digitization (EU digital strategy) is creating new opportunities and challenges for the green industry. In order to successfully step forward into the digital future, it is important to know the right tools and use cases.

In the previous project "Green BIM. Building greening as part of BIM-based planning and maintenance", the criteria for BIM-based planning over the entire life cycle (planning, building, care/maintenance) – the so-called "Green BIM-IFC data structure" including information for the buildingSMART Data Dictionary (bsDD) – as well as the corresponding client information requirements (AIA) were developed.

The results were based on a comprehensive status quo analysis of existing building greening projects and were successfully presented to stakeholders and users in fall 2022. In addition to these requirements for the data structure bases, the "Green BIM" research project also developed bases for requirements with regard to different levels of detail of model information in the course of a project.

These refer to different levels of alphanumeric (LOI) and geometric (LOG) detailing as well as detailed specifications for the modeling of green building systems. In addition, phase models and process patterns were elaborated for 3 case studies.

Contents and goals

With the project "Green BIM 2" the technology leap from the previous project "Green BIM" – namely the use of BIM in the field of building greening – is continued for further application fields of landscape planning and the results are transmitted into working practice.

Methods

Specifically, the Green BIM results (IFC data structure, bsDD extensions, adapted AIAs, 3 use cases with the prototypical process patterns) will be tested in working practice by the 7 partners of practice ("Green BIM Users"). This will be done with real planning projects along the entire planning process chain and work phases - from design planning, to detailed planning and construction planning, to tendering, construction and green maintenance, as well as after-use.

After the practical proof of concept, the "Green BIM-IFC data structure" will be updated and complemented in BIMQ for working practice and further fields of application of landscape planning. Focus lies on the one hand on the leap from building greening to horizontal landscape planning as well as from site planning to urban planning, but also in particular on interfaces towards software programs in the field of tendering and green maintenance.

The interfaces of BIM & building certification as well as sustainability assessment will also be analysed. Performance indicators for Green and Blue Infrastructure, BIM workflows for ecosimulations and real-time monitoring concepts for Green and Blue Infrastructure will be defined and it will be analysed how these data could be integrated into BIM.

Further use cases and process patterns will be developed for this purpose. Accompanying learning courses and material for 3D and BIM application in the green sector will be provided to pave the way for the actual application of the results in working practice. Ultimately, it is planned to involve the relevant stakeholders to promote the international certification of the "Green BIM-IFC data structure".

Expected results

The project contributes to advancing digital and data-based climate-resilient urban neighbourhood planning and large-scale greening projects in the horizontal surface. The planned timely integration of landscape architecture in BIM models goes well beyond the state of the art and creates a significant knowledge and technology advantage for the green industry in general.
