How to Work with a Building Information Model (BIM) for Life-Cycle Assessment?
BIM & Life-Cycle Assessment (LCA)
• BIM (Building Information Modeling)encourages integrated design & enhances collaboration amongst stakeholders throughout project life-cycle phases.
• Life-Cycle Assessment (LCA), on the other hand, is an appropriate technique for evaluating environmental performance.
Design guidelines for a BIM appropriate for LCA automation: • Apply uniform & clear material labeling • Prefer layered elements for multiple • material items • Model objects as hollow • An export model with steel reinforcement • Verify elements & categorize them as per IFC • Never be concerned about problems in model • components needless for LCA
•
Apply uniform & clear material labeling
• Ensure that the labels are legible and accurate (using specific technical references).
• Instead of Airspace, Foreground, White, etc., use ready-mix concrete, cast-in-place, or steel steps.
• Speak in your native tongue.
• Avoid definitions in conflict with one another by using precise material designations whenever possible, like ‘Concrete’ for one object's material & ‘Brick’ for another.
2. Prefer layered elements for multiple material items • Apply objects that have the necessary materials with applicable thicknesses, including potential airspaces • Apply labeling like an interior wall, gypsum and steel studs to your objects' labels if they are specified as solid objects
Model
hollow • Model items as hollows or else indicate in labeling when they are intended to be hollow. • You should refer to your slabs as hollow core slabs if hollow items are shown as solids.

4. Export model with steel reinforcement
• Structural models can be saved with or without reinforcements for ease of use.
• While utilizing a model for LCA, it doesn't have reinforcement steel incorporated in the concrete
• You will need to manually add the proper amount of reinforcement.
5. Verify elements & categorize as per IFC
• To prevent ambiguity & mistakes in the application & analysis of the model, BIM engineers have to verify elements & categorize them related to IFC.
• If the classification is incorrect, your scope may be incorrect because it will be utilized for filtering.
6. Never be concerned about problems in model components needless for LCA
• Only the structure & enclosure should be included in LEED v4 LCA • Verify the necessary scope with your client, and then concentrate on it
