General / Re: Import of a NXT Efficiency Model posible?
« on: June 02, 2016, 13:26 »
Hello Christian,

it is not possible to import an Umberto model created in Umberto NXT Efficiency, into the smaller version Umberto NXT CO2. This is because the material and energy flow models in Umberto NXT Efficiency can contain cost data, which is something not available in Umberto NXT CO2.

Also, please keep in mind, that the models typically differ in regard to the setup: While in Umberto NXT CO2 you probably would build a product life cycle model to calculate the carbon footprint of a product, the perspective of the model in Umberto NXT Efficiency is on the material and energy flows and the associated costs within the company or a group of companies, and the company's activities e.g. within a business year. 

BTW, you know that there is carbon footprint data also in Umberto NXT Efficiency? Why do you want to import the model into NXT CO2 at all?

While reading the ecoinvent v3.2 Change Report [Moreno Ruiz E., Lévová T., Bourgault G., Wernet G., (2015). Documentation of changes implemented in ecoinvent database 3.2. Ecoinvent Centre, Zürich, Switzerland], section 2.9 on changes in impact assessment methods caught my attention.

There was no general update for LCIA methods with the changeover from ecoinvent v3.1 to v3.2, but there have been changes to the IPCC2013 implementation, that deserve a mention here, as it will affect the LCA results of our users who work with the IPCC2013 method.

The report on page 16 explains that "ecoinvent has decided to exclude near-term climate forcers and to opt for CFs without the carbon-climate feedback effects". Also, some characterization factors (CF) had to be corrected. Therefore, "due to these significant mistake corrections and  change in methodological choices, we recommend not to use the impact assessment scores calculated for 3.1 for IPCC2013".

Apparently, when the IPCC Fifth Assessment Report (AR5) was released in 2013, due to some changes and differentiations in the method, the extraction of the most appropriate characterization factors (CFs) wasn't really trivial. Values with and without carbon feedbacks were given. For example, for methane, a GWP100a value of "28" was suggested if not considering carbon-climate feedback (CCFB), and a value of "34" was proposed including the carbon-climate feedback. ecoinvent at the time of releasing ecoinvent v3.1 had opted to go for the higher value with CCFB (see screenshot).

This decision has now been rectified and the implementation of IPCC2013 has been corrected.

Umberto NXT users who install the new ecoinvent v3.2 database and then update their existing LCA projects should be aware that the results of their LCIA may change, if they are using the IPCC2013 method. The characterization factors are attached to the elementary flows (e.g. methane, fossil) and thus when updating from v3.1 to v3.2, this may eventually lead to new LCIA results.

Please see the attached screenshots to see the difference for the elementary flow "methane, fossil". In IPCC2007 the GWP100a value was "25" (from AR4, 2007). In the implementation in ecoinvent v3.1 the CF was changed to "34". In the new release ecoinvent v3.2 it was changed to "29,7", based on the unrounded original value of "28,5" from source table 8.SM.17 in AR5 and an addition of "1,2" to account for the difference in impact on climate change between "methane, non-fossil" and "methane, fossil" as described by Boucher (2009). The GWP100a CF for "methane, non-fossil" is at "28,5" rather than using the rounded value "28" given in source table 8.A.1 given on page 731 of the AR5.

ecoinvent has published a 14-page report on the issue that explains in detail the reasoning for the changes in the implementation. This report [Bourgault G (2015). Implementation of IPCC impact assessment method 2007 and 2013 to ecoinvent database 3.2] is available to users logged in to the database in the 'Files' section (file 'IPCC implementation_v3.2.pdf'). Make sure you read it should you be using the IPCC2013 method in your LCA project.

Global Temperature Potential GTP20a and GTP100a characterization factors are now also given in the IPCC2013 implementation and can be used in addition to GWP.

The CFs are the ones without climate-carbon feedback (CCFB). According to the above report "the values of GWP and GTP with CCFB are not published for all gases [in the AR5]. Only the values without CCFB are available for CO, NOx, SO2, VOC and fossil methane. Until all CFs are available with CCFB, only the metrics without CCFB are implemented."

ifu Hamburg can assist you with your LCA project. Should you need help or wish to discuss the implication of the changes described above, please contact our Umberto Support Team.

Click on the below screenshots to enlarage them. The first screenshot is from ecoinvent v3.1 in Umberto NXT, the second one for ecoinvent v3.2 in Umberto NXT (currently being tested, release is imminent). Boths show the CFs for 'methane, fossil' from the IPCC2007 and IPCC2013 LCIA methods (other LCIA methods are collapsed and values not visible).

Data (ecoinvent v3, GaBi) / What's new in ecoinvent v3.2?
« on: December 11, 2015, 09:59 »
I am currently previewing (beta testing) the implementation of ecoinvent v3.2 LCI data in Umberto NXT LCA.

ecoinvent has published the datasets on Nov 30, 2015 and ifu Hamburg (just like other LCA software makers) now has the task to include the datasets in their software, test them in their LCA models and ship the new software package with ecoinvent v3.2 database to their customers.

An official shipping date for Umberto NXT with the new database has not yet been announced. Christmas holiday season is just not the best time of year to deliver a new product to the market...

Here are a few impressions regarding the new database. This is a subjective selection only. Those of you interested in a comprehensive summary of the changes and new items in ecoinvent v3.2 should read the official Report of Changes provided on the ecoinvent website. [Moreno Ruiz E., Lévová T., Bourgault G., Wernet G., (2015). Documentation of changes implemented in ecoinvent database 3.2. Ecoinvent Centre, Zürich, Switzerland]

  • Many updated datasets, a number of new datasets: Approximately 2200 datasets have been updated, an estimated 300+ datasets have been added. Updates may be due to changed energy input, new, split or modified geographies, new technologies, or simply due to removal of errors detected.
  • New energy datasets: News energy data for 32 regions in China.
  • Many new activity datasets for Quebec (geography CA-QC). The cooperation between CIRAIG and ecoinvent continues to yield many new datasets. Good for Canadian/Québécois users
  • New agriculture activity datasets, e.g. swine production, oat grain, maize solage, various grains used as feed.
  • New refrigerated transport datasets: refrigerated transport for different modes of transport (cooling container on ship or train, cooled goods on aircraft and cooling truck). A good addition especially for LCAs in the food sector.
  • Introduction of market groups: This will probably be the most helpful feature for many users, particularly in Europe. Market groups comprise several (national) markets. They are available e.g. for energy and heat in Europe or for China. Market group datasets merit an own post (coming soon)

It should also be noted that the system model that has been previosly recommended as the default for allocation has been renamed in ecoinvent v3.2 to system model 'Allocation at the point of substitution' (abbreviated as "APOS"). The APOS system model is explained on the ecoinvent website: "The APOS system model was previously called "Allocation, ecoinvent default". The name was changed with the release of ecoinvent version 3.2."

It was probably not a light-hearted decision by the ecoinvent experts to return to advising the use of the cut-off approach: "For users new to LCI databases, ecoinvent recommends using the cut-off system model when starting to work with ecoinvent version 3. This model can be easier to understand for first time users. The cut-off system model applies the same modelling choices as ecoinvent version 1 and 2. This system model is therefore also recommended for experienced users looking for continuity with their previous work."

As for the impact assessment methods (LCIA) it is worth mentioning that the implementation of the IPCC2013 method in the ecoinvent v3.2 release has been modified, and that its application will most likely yield results different to the ones of the the IPCC2013 method provided in ecoinvent v3.1. A more detailed description of this issue can be found in this post.

This page on the ecoinvent website is also a good starting point to learn what's new in ecoinvent v3.2

General / Re: Paste of Live Link data failed
« on: December 10, 2015, 09:44 »
The issue is being handled bilaterally with alex111 via our Umberto Help Desk. Users can always send their support inquiries directly to support@umberto.de. It is recommended to include the log file that includes further leads as to what may have caused the error.

In the case described, the creation of the Live Link failed. There may be several reasons for this: The Excel file ist not accessible. It might have been renamed or modified, it might be on a disconnected network drive, or it may be read/write protected. The log file gives further details on the issue.

Hallo Sabrina,

der Prozess war zunächst mit Input/Output-Koeffizienten linear spezifiziert. Wenn jedoch zusätzliche Funktionen/Formeln angegeben werden sollen (hier für die Kostenrechnung), so wandelt man die Transition um in eine Spezifikation 'User Defined Functions' (der Button mit dem Wurzel-Zeichen). Man wird dann darauf hingewiesen, dass man von der linearen Spezifikation mit Koeffizienten weggeht, und die Spezifikation mit mathematischen Formeln macht will.

Der Assistent im 'Edit User Defined Fuctions' Fenster erlaubt zunächst mit einem Klick die Input/Output-Koeffizienten als Zuweisungen zu übernehmen.

Die Kostenentstehung in Abhängigkeit von der durchgeflossenen Menge im Prozess und/oder in Abhängigkeit von anderen Bezugsgrößen (Cost Drivers, z.B. Maschinenstunden, Wartungsintervalle, ...) kann man darunter mit Formeln eingeben.

In diesem Fall arbeitet man nicht mehr mit der Spalte der Koeffizienten, sondern eben mit den mathematischen Formeln.

Wenn man das versehentlich von 'Input/Output Coefficients' in 'User Defined Functions' umgewandelt hat, und das wieder rückgängig machen will, so kann man es mit dem entsprechenden Befehl aus dem Kontextmenü der Transition versuchen. Das geht aber nur wenn man noch nicht weitere (nicht-lineare) Formeln eingegeben hat.

Im Benutzerhandbuch ist das alles ganz gut beschieben.

Noch eine zusätzliche Bemerkung. Die Version Umberto 3.6 ist ja schon recht alt. Ich glaube aus dem Jahr 2004 oder so. In der aktuellen Version von Umberto (Umberto NXT) kann man inzwischen die lineare Kostenverursachung auch wie einen Fluss mit Koeffizienten angeben.

Viele Erfolg weiterhin mit dem Masterprojekt.
