As part of the Nordic harmonisation of life cycle assessment, the main objective of the BIM4LCA project is to support regulatory harmonisation and create best practice guidelines for BIM-based building LCA and material declaration.
Information harmonisation
The BIM4LCA project highlights the need for Nordic authorities to set BIM requirements for climate declaration and support information harmonisation in the construction sector. The project emphasises the importance of integrating BIM and LCA processes to achieve sustainable construction goals.
The BIM4LCA project produced several results, which are here shortly summarised:
Generic description of the BIM to LCA process
... supporting the calculation and reporting of normative LCA in building construction projects and a pathway towards automated BIM-based LCA for instant feedback and low-carbon design solutions Go to section 1 in the report
Generic guidelines for reliable BIM-based material inventory (bill of materials)
Specifications for information needed for modelled building components, data transfer from BIM tools to LCA tools, and iterative design and analysis workflow between BIM and LCA tools Go to sections 2-7 in the report
BIM models to download
Two example buildings with BIM models for practitioners to learn BIM-based building LCA Go to section 8 in the report Download BIMs and IFC files here
