Provisions |
Preprocessing should be considered in the context of a complete LCA. The manufacture of prefabricated building products should be included in Modules A1–A3, and their transport in Module A4. The impacts related to their installation (waste, machinery etc.) should be included in Module A5. | |||||
Rules from: |
EN 15978: 8.5 Scenarios for the construction process stage (Modules A4-A5) | |||||
Guidance |
The practitioner should use detailed calculation for a complete LCA, based on specific data (e.g. EPD information for Module A5). | |||||
