Changes in process input not showing up in results
Hi I have noticed a problem; when I am trying to change the mass input of a flow in a process, the final impact assessment is not changes. I am changing the input with 15% but the final climate impact is exactly the same as before. I have tried to delete the product system and to restart the program...

Re: All the impact analysis results are zero
Hej I have the same problems for some of my processes in my product system, I tried follow your suggestions above but cannot find whats wrong. This is only for two of the processes in the product system (also, these do not show any impacts when running calculations of these separately, not even inpu...

Re: Uncertainty and LCC
Hey Andreas, What I have done is to add different costs to the different processes in the energy system where some costs are dependent on the electricity price and some are not. To calculate the effect of inflation, different impact methods have been created that multiplies the running costs of the ...

Uncertainty and LCC
We are doing an LCC-model for an energy system. We want to know how different energy prices affect the total lifecyclecost of different energy sources. We want, for example, to test different energy prices using the uncertainty function. We have tried to change the uncertainty function both in the p...

Error in impact assessment
I have a lifecycle divided into three parts: manufacturing, use phase and end of life treatment and wants to compare two different products. The manufacturing is different, but the end of life and use phase are the same for the both cases. For case 1, the impacts from the manufacturing are less than...

Cheat Sheet for Recycling wanted!
Hi
I am trying to model a recycling scenario. What is the easiest way to do that? I looked at the tutorial for the Case study: Beer Bottle, but for me, the information given wasn't enough.

Negative Results for Resource Use
Hi I am doing an LCA of bio-composites and the environmental impacts from the choice of polymer (PP, PLA or bio-PE. For my resource use category, the impact turns out to be negative (the most negative for PP). When I make a product system, just comparing the polymers, the results are all positive. I...

Question about System Expansion
Hello I need to do a system expansion for my process in order to give my material credit for the heat gained when incinerated. In the wiki (http://www.openlca.org/documentation/index.php/Advanced_functions#Handling_multi-product_processes) it says that there should be an avoided product box in the i...
