Issues writing amounts
Hi I am using a new Mac OS High Sierra 10.13.4, a 2.3 GHz Intel Core i5, 2 memory slots, 4GB Ram (8GB total); 1 TB SATA Hard drive and the new openLCA version 1.7, just downloaded today. I have ecoinvent database 3.3 (both unit and system processess). Every time I write the amounts for each flow, in...

Water footprint Assessment AWARE method
Hello OpenLCA Team As I understand ecoinvent 3.2 datasets are now balanced. From the inventory results I get some water flows represented in Kg, and others in m3. I am attaching image of and excel sheet I used to understand LCI results from coal power generation model. Inventory_Analysis.png In exce...

loops in electricity losses, ecoinvent 3.2 (cut-off)
Hi I am trying to understand how are electricity lossess modelled in ecoinvent 3.2. cut-off system model. For this I am using the Mexican electricity datasets. My confusion arises from the fact that in the version 3.2 of ecoinvent datasets, electrical lossess are modelled as additional inputs of the...

Display bugs on openLCA 1.5.0 Beta
Hello Andreas thanks for all your replies to my queries. I´ve notice some display bugs on your 1.5.0 beta version. I am running on a Mac OS X El Capitan, and I have been noticing the model graph from the product system does not update a process once you change it. Instead I need to close the product...

Modelling Transport in Markets or Directly?
Hello I would like to understand how to model a transport process a little better. In the examples on the PET bottle, the weight of the materials (kg) is multiplied by the distance (km). And it is used directly on a transport process. For my case study, I am modelling coal transportation distance in...

Plus signs on graphs and creation of product systems
Hi I would like to understand why when you create a product system using Ecoinvent datasets, there are some additional processess (some times markets) on the output side of the graph even though these are not shown in the output table of the process. Do these have any effects on impact assessment? I...

Modelling approaches using Ecoinvent Datasets
Hi there! I am using the ecoinvent allocation cut-off system models datasets, and I modelling the energy mix for Guatemala as a case study. I am used to copying and pasting processess and then changing values to adapt them to local conditions. Usually reverse engineering entire ecoinvent energy syst...
