FEDEFL in openLCA

Creating a FEDEFL Database in openLCA

These instructions describe starting a new openLCA database with the FEDEFL as the reference flow list.

1. Create a new openLCA database with just units and flow properties by right-clicking on the navigation pane and selecting New database.

2. You will need to import the master version of the FEDEFL into your database. To do this you can download a JSON-LD file from the Federal LCA Commons. Select elementary_flow_list repository under the Federal_LCA_Commons Group/Repository.

3. Select Download Respoitory as JSON-LD

4. Once the FEDEFL is downloaded to your computer, navigate to your openLCA database, right-click on your open database and select Import

5. Select Other, Linked Data (JSON-LD).

Select Next and navigate to your JSON-LD file location in Windows Explorer downloaded from the Federal LCA Commons website and click Select Folder. Files in the chosen location will appear in the openLCA import window. Select the master FEDEFL file and click Finish to begin the import process. It will take several minutes for the FEDEFL to import into your database.

6. Confirm that your flows have imported. An example of the FEDEFL flow folder structure in openLCA is shown below.
