question about regionalized LCIA and what kind of computer can operate spatially explicit LCIA

Question

Hi all, I'm doing the regionalized LCA currently, and I use Impact World+ as the regionalized LCIA, based on the Ecoinvent V3.8 database. But I faced a big problem. Because I found my laptop is not able to operate OpenLCA for spatially explicit LCIA calculation,  it usually quit without any warning. I'm sure it's not the problem of my database or OpenLCA on my side, because when I click the 'Analysis' function, it works perfectly well. I wonder if any of you know what kind of computer or laptop can operate regionalized LCA on OpenLCA, or how big the computing capability should be alright for regionalized LCA operation in laptop or computer.

Answer 1

If you switch to openLCA 2 it should work. In 1.x, the calculation was fine but quite resource-intense, the initial calculation took hours, literally, this is now much improved. Check the handbook e.g. for details: https://manuals.openlca.org/openlca/, and specifically https://manuals.openlca.org/openlca/advanced_top/regionalized.html.
