Re: Normalisation / single score

Dear Andeas, Sorry but my point was not that. Consider a product system that I want to calculate its effects based on eco-indicator 99 (H/A). When any normalization set is not added to the software the results are based on points! When a normalization set is added to the software the results are bas...

Landfill inventory year

Hello everybody, I'm modelling Landfill in OpenLCA and I want to calculate the emissions in a specific year of Landfill's life years. I didn't find anything related to inventory year of Landfill. There is a "Time" box in the process, General information tab. If I select the start date of 1994 and en...

Input/Output method on OpenLCA

Hello everybody, I’m modelling landfill emission by openlca and as a validation method, I want to compare the results of Landgem model (Developed by EPA) with openlca. So I want to convert output flows of Landgem to midpoint and endpoint effects on openlca. I tried that and I entered Landgem emissio...

Re: System expansion: "avoided product" not calculated

Hi Mara, I have an experience with "avoided product" with openlca, actually the avoided emission of electricity production from landfill gas capture. 1- By trial and error, I found out that when the entire supply chain of the main process is available, the "avoided emission" take into account. But a...

Re: Normalisation / single score

Capture.PNG Dear Andreas, Thank you. but the only problem is that when the OpenLCA LCIA method is not added (so there is no normalization and weighing set), calculating the result (say Eco-indicator 99, (H,A)) leads to normalized scores in terms of points. but when the OpenLCA LCIA method is added,...

Re: Normalisation / single score

Dear Andeas, Thanks for your explanation about reference sources of IMPACT 2002+ LCIA method. But I have a question. when I use Ecoinvent LCIA method the impact results are in term of "points", i.e. the normalization process is performed already, although I've not selected any normalization method. ...

Re: Landfill modelling

Hello, After you imported the database (like ecoinvent_consequential) and the LCIA method, you can select some predefined processes (like landfill of municipal solid waste, collection and transportation) and after that you should "create product system". then a product system will be created based o...
