Full life-cycle calculation (LCA) from the model
DES-LCA · General · Design
Carry component quantities and materials in the model so a full LCA is possible without parallel quantity lists.
Starting point
- Life-cycle assessments need reliable quantities and material data; these are often missing in the model or only live in spreadsheets.
- Manual rework for SNBS, KBOB, or LCA tools is error-prone and delays decisions.
Goal & benefit
- Provide architecture and structural components with material and quantities as the LCA basis.
- Enable earlier, repeatable life-cycle calculations instead of late one-off rework.
Process
- Carry governing components with geometry and material in the model.
- Extract quantities (volumes, areas) and material indicators from the model.
- Transfer the data into LCA/certification tools and compare variants.
Outcome
- Model-based input data for a full life-cycle calculation (LCA).
Deliverables
- Architecture and structural model with IfcProject, IfcSite, IfcBuilding, and IfcBuildingStorey
- Governing components (walls, slabs, roofs, columns, beams, foundations, facade and fit-out elements) with material
- Quantity attributes (e.g. GrossVolume, GrossSideArea, GrossFloorArea) per component
