In today´s urban planning, vertical greened buildings and innovative horizontal vegetated areas are more commonly implemented which leads to an increase of physical comfort in people living or working nearby. Especially sophisticated, technological greeneries as green facades on roofs require holistic approaches and planning which integrate the on-going operation as well as the maintenance- apart from the conducting and installation process. Still, it looks quite differently in practice. It is still very uncommon to consider the whole lifecycle of systems from the very beginning. These problems are addressed by the research project “Green BIM” to eliminate them.
Building Information Modelling, abbreviated BIM – a modelling database containing all necessary information for optimized planning, conducting and management regarding buildings – is already implemented in (general planning-) agencies and involved to a standard tool of successful, holistic planning. Yet, a widespread implementation in the field of landscape architecture is missing. The project “Green BIM” faces the challenges and implements greeneries both in and outside (on the facades) of buildings in the BIM process and edit existing standards (IFC/ISO 16739) according their planning and life cycle- implementation in BIM.
In this project, comprehensive status-quo-analysis of existing vegetated buildings are the basis to elaborate criteria for holistic and whole life cycle (planning, conducting, care, maintenance) considering BIM-based planning. “Green BIM” determines with specific case studies both how to model greened systems using BIM and how to successfully digitalize existing greened systems retrospectively. By analysing the case studies, “Green BIM” examines to what extent typical steps in planning regarding greened buildings can be edited by characteristic software programs in a BIM-equitable way.
The aim is a fusion of greenery and BIM planning to achieve a friction-free conducting and maintenance. The findings and outcomes are of utmost relevance for all organizations related to both building and greenery planning or maintenance, technology suppliers, authorities and administrative bodies, energy/building consultants, planners, building-services engineers and facility management.
The final outcomes of the research project are supplements to international standards for data structures in civil engineering (IFC / ISO 16739) which are further on added to BIM applications by the software industry. This enables the accessibility of this research projects` findings for a broad spectrum and mass of users.
