Ecoinvent 3.1 - Different Files

Until now I was working with OpenLCA Version 1.3.4 and econinvent 2.2, but yesterday I tried to update my system. OpenLCA 1.4 looks really finde, but I habe problems importing the right econinvent file, because there are 6 zolca-files offered. Whats the difference between the _LCI and the other file...

Creating flows and processes

1. If I'm creating an elementary flow, i don't know what I can do with it. I can't define a process for this flow, which means that the "value" of this flow is zero. What's the intention of the possibility of creating an elementary flow? 2. Is it possible to re-model a flow (e.g. from ökobaudat or s...

Elementary Flows

If you create a new database including reference data, you get a lot of elementary flows. I was very surprised, that also many ecoinvent flows are using these elementary flows. Where do these elementary flows come from? And what will happen with my ecoinvent data, if I'm deleting these elementary fl...

Re: Importing Ökobau.dat

Hello Andreas, thank you for your prompt reply. We are a University of Applied Sciences (http://www.technikum-wien.at/studium/master/erneuerbare_urbane_energiesysteme) and would like to offer the Ökobaudat Database to our students. Is there a way without paying for the database? Thank your very much...

Re: Importing Ökobau.dat

Hello Andreas, I have the same problem like Juan. I downloaded the database vom http://www.nachhaltigesbauen.de/baustoff-und-gebaeudedaten/oekobaudat.html and tried to import it (ILCD). It seemed to work, but making a product system out of a process, everything is 0.00. Is there a reason for this pr...

Import Single Process

I have 2 questions, concerning the import procedure in openLCA: 1. Sometimes I need only 1 process from from a database (e.g. bioenergiedat) for my data model. I don't want to import the complete database. In case of bioenergiedat I have the possibility to Import a single process via ILCD network im...

Re: Using Ecoinvent in OpenLCA (for the beer bottle case)

I just found out, that ecoinvent will work, if i'm importing the nexuspack-file into an empty projectdatabase. Importing it to the database from the beer bottle sample results in strange results. Do you have an explanation for this behaviour? It's the same with NEEDS... ELCD still not works, no matt...

Re: Using Ecoinvent in OpenLCA (for the beer bottle case)

Thanks for your reply. I'm not re-modelling the whole beer bottle example. I'm trying to compareonly one concrete process - from NREL the electricity, at grid, US and from ecoinvent the electricity, medium voltage, at grid, US. To compare it I made 2 productssystems based on these processes, to comp...

Re: Search Flows and Processes + Allocation method

Thank you for the prompt reply! 1. great! thank you - i haven't found it myself! 2. and what if a process has more products? 3. yes, I can have a look at the processes, but if I would like to know the fossil energy consumption of a flow or a process, I have to make a produktsystem out of it. Do you ...

Re: Using Ecoinvent in OpenLCA (for the beer bottle case)

Thanks for your prompt reply. I'm aware of the fact that there are diffences, but not with a factor 1.000.000.000.000 - this seems to me more or less like a calculation error... maybe a problem with the unit... and the NREL data is at least plausible, but the ecoinvent data is wrong. I have the same...
