different LCIA results in openLCA 1.3.4 and 1.4?
Posted: 25 Apr 2014 15:03
Because openLCA 1.3.4 runs slow on my computer using the ecoinvent 2.2. (2010) database I installed the openLCA 1.4 demo version. Also because I work with ecoinvent 3.0 and was glad to see that openLCA is now able to handle this version as well.
However, I get different results using the same processes in openLCA 1.3.4 and openLCA 1.4.
I am not a regular openLCA user, so I might did something wrong. Here what I did:
I exported my old openLCA 1.3.4 database (containing mainly ecoinvent 2.2. data) as .zolac file with the openLCA data migration plugin and imported it as a new database to openLCA 1.4. demo.
I created a product system, containing an ecoinvent process on the production of a PV panel. Then I ran the calculation “Analysis” for IPCC2007. The LCIA shows other results (negative values) compared the the results in openLCA 1.3.4 for a product system, containg the same process.
I checked with the ecoinvent database online. The results from the analysis in openLCA 1.3.4 correspond to the results directly obtained from ecoinvent. Why did I get totally different results in openLCA 1.4 demo?
Thanks for your answer.
