I downloaded the NREL LCI database (National_Renewable_Energy_Laboratory_USLCI) in JSON format, as a Zip, and decompressed it. When I try to import it (New Database > Processes > Import > EcoSpold > Choose Directory, it just opens the file (which contains subfolders "currencies", "processes", "dq_systems", "locations", "actors"... etc., which contain the JSON files, and I am thus not able to click Next (it's greyed out).

I also tried importing the .zip file but it is greyed out when I go to choose the directory.

How do I import the NREL LCI database?

Appreciate any help on this!

Dowload the NREL database from https://www.lcacommons.gov/lca-collaboration/National_Renewable_Energy_Laboratory/USLCI/datasets as JSON-LD file. Create a new empty database and import the JSON-LD file (ZIP-FILE without prior unpacking!; select JSON-LD import).

I have tried to follow the instructions provided by Jonas but am unable to import National_Renewable_Energy_Laboratory_USLCI.zip into openLCA. After downloading the JSON-LD file from the website Jonas provided, I created a local, empty database in openLCA. I right click on the name of the new database and select import. A pop-up window appears. I select "Linked Data (JSON_LD)" under the "Other" folder and click "Next." From my downloads directory, I can select the zip file and click "Finish." The window closes faster than I would expect and none of the data is in the new database. That database is still empty. I don't understand what I am doing wrong. I'm using openLCA 1.8.0 and macOS Sierra version 10.12.6.  Thank you in advance for your help!

I have some problems related to this. I have downloaded the NREL database from that link, but as ILCD file. Then, I imported the zip file into openLCA software. but when I click 'Calculate' for the product system, an error occurred. Calculation failed..

Hi hana, your description is somewhat unspecific. Please open a new question with more information and also try JSON-LD which is openLCA's native format.
