The database imported fine in just a few minutes.ģ) I activated the imported database (Fig.3).Ĥ) I moved all processes to a subfolder called “_LCI” to be able to distinguish these from UPs in the future (Fig.4a and Fig.4b)ĥ) I used the “same” import database function and selected the ecoinvent3_1_cutoff.zolca database (Fig.5a). So I tried the procedure you outlined (Figures are in the attached picture)Ģ) I imported the ecoinvent3_1_cutoff_lci database using the “Import database” function (Fig.2a and Fig.2b). Indeed, the procedure I tried did not yield any fruits: all the process categories from the “importing” database (ecoinvent3_1_cutoff) were copied into the “receiving” database (ecoinvent3_1_cutoff_lci), but no process data was copied. Has anyone else succeeded in merging the databases? How long did it take you? I know that merges can take a long time, but do these times seem OK given the task and my system? I will leave it running for another 8 hours - then I need to turn off my computer. The process has been going on for 12 hours now. Import took about 5 minutes.Ħ-Activated “ecoinvent3_1_cutoff_lci.zolca”ħ-Moved all processes to a folder (child of process folder) called “LCI” to be able to distinguish these datasets from the UP datasets I wanted to import to have a merged databaseĨ-Clicked "Import" and selected “existing database”, then “ecoinvent3_1_cutoff.zolca” from drop-down menu. Import took about 2 seconds.ĥ-Repeated 3-4 for “ecoinvent3_1_cutoff_lci.zolca”. Has anyone else been able to import these databases?ĭid you find a difference in import time between an import in an "empty" database (with only reference values) and a database that already contained process data?īased on your answer, here is what I did:Ġ-Deleted all existing databases (I wanted to start with a "clean slate")ġ-Created an “empty” database with reference dataģ-Right clicked and selected “import database”Ĥ-Selected “ecoinvent3_1_cutoff.zolca”. OpenLCA seems to consume about 20% of my CPU and 25% of my memory during import. Processor Intel(R) Core(TM) i7-3632QM CPU 2.20GHz, 2201 Mhz, 4 Core(s), 8 Logical Processor(s) * I have just launched the import of ecoinvent v3.1 cut-off UP and await results - 7 minutes and running. Again, most datasets seemed to be there, but I could not be sure. * The ecoinvent v3.1 cut-off LCI database was not finished after 12 hours, and I had to kill the application (cancel operation did not function).

Most datasets seemed to be there, but I could not be sure (I don't know how to count datasets in a folder). * The ecoinvent v2.2 LCI database was not finished after 3.5 hours, and I had to kill the application (cancel operation did not function). * The ecoinvent v2.2 unit process database imports like a charm. zolca file", and navigated to the appropriate. >clicked "import", selected "other/database import", selected "from exported. On a side note, these latter services are not free of charge.I have tried importing the ecoinvent database using the import openLCA database import function. Researchers and managers who require further assistance can obtain it along with tailored services and specialized tools that can be more appropriate for their current project. In fact, the framework can be used for uncertainty calculations via the Monte Carlo simulation and later on exported to Excel conveniently.ĭue to the fact that the program is open-source there are several free databases and many of them can be used as background data for a custom LCA or sustainability study. Some features worth mentioning include the GIS integration, the potential to work with very large databases and systems, the possibility to include unassessed indicators as well as automatic and graphical modeling. The program can come in handy in the Sustainability and Life Cycle Assessment, which is quite a vast field with implications in various industries and research, as it focuses on fundamental issues such as Global Warming, CO2 emissions as well as their social and economic impacts, for instance.Īccording to the developer, the latest edition encompasses unique features that can provide accurate predictions for a Life Cycle Assessment research. OpenLCA framework provides you with a user-friendly graphical modeling tool that focuses on life cycle assessments. Process-specific Monte Carlo Simulation results.
