ReCiPe08 - LCIA comparison drawing >6 IC with minus values

Post by Ants » 06 Sep 2013 15:12

Dear Forum,

I am actually performing my impact assessment with "more" than 7 impact categories (in this case ReCiPe2008) ... and I found a very interesting system behaviour I would consider as a bug.

Context: I have two product systems which I am comparing within a project
Description step by step:
(1) in the comparison tab of my project I have selected the ReCiPe Midpoint (E) as LICA method with all impact categories to be drawn on the chart - the result you can see in Screenshot 1. A strange behaviour, the water depletion is " minus %" ... so I thought that there must be something wrong with my data

Screenshot #1 _ minus value on WDP

(2) after checking my data in detail I found nothing wrong... so I did a test... I took away the impact category water depletion (remember position No.7) and did the drawing again - please see screenshot 2. Result: Now it is not the WDP anymore... the "minus %" again is on position No.7 but this time it is terrestrial ecotoxicity .

(3) Has to be a bug I thought - therefore now the last test... I randomly took "7" impact categories and made a bet with myself... see the result in screenshot #3 _ PROOF.

Conclusion:
In case you do not tell me otherwise _ if you select more than 6 impact categories (at least valid for ReCiPe2008) .. you receive this bug. I will try to check in Excel if this is somehow a calculation error or only a bug in display.

Or do you have any other ideas?

Thanks for your help,

Andreas

Hi there,
I noticed the same bug using eco-indicator 99, (H,A) concerning position 1,8,10,11,12
