Creating Product EPD from dowloaded EPDs

Question

I am creating an EPD based on imported EPDs for the products suppliers , downloaded fro EPD International by ILCD and via Soda4LCA. Creating Flows and Processes based on the imports for the product im trying to create an EPD from using EN 15802 +A2. Att product system dragging the EPD result from the downloaded to Product system, starting with the A1-A3, and it works so far . After calculation  i only get results on Flow level , not on impact level, impact analysis only gets zeros. Any Tips

Answer 1

Which LCIA method did you select? We are now using UUIDs from EF for the EF-based categories for our LCIA EN15804 method, e.g., so this should work in principle, but I am aware that not all published EPDs use the supposedly to use category UUIDs and thus this will not work. Maybe you could post more details, thank you.

I have used the EPDs as they are imported , used the EN15804 A2 method . I do not really understand the UUID thing here. When i check Database linkage i get a lot of  "Product System Creation :Linking Option"  Process without default providers . im using "OpenLCA LCIA methods 2_1_3 for the 15804 method
When calculation Product System and at the LCIA Checks Tab , there are almost all Flows fom 15804 there not covered . So what to do ??

ah, the "UUID thing": these are ids used to identify (again) things. You see these in openLCA for all larger elements. You need to use the EN15804 method that is part of our EN15804 extension.

Using EN15804 A2 when im calculating Product Systems , but get no data on "Contributing to Impact Categorys" but data on "flow Results" when calculating on Process i get nada.On the Product systems i have graphically linked in the contributing EPDs result on tex A1-A3 level  What im i doing wrong ?

---

the impact method does not fit to the EPDs

---

So how can do this , the EPDs i imported are EN15802 A2 ?
Do i have to key in the EPDs Results by hand and chose the 15802 im using when calculated and then use them in the product systems or is there a sniekey  way of get the in ?


Now using EF 3.1 it somewhat working but all the GWP is zero , hmm

you need to use the EN15804 method available in the EN15804 database, then it works *if* the EPDs follow the common UUIDs for the impact categories (which is often the case but not always, but evidently not in our hands)
