Re: Base nomenclature - theory into practice

Miguel Fernández Astudillo


Having a look to the state of the wiki of the openenergyplatform, it does not seem that the ontology has advanced much. but it would be worth double-checking with Ludwig Hulk and or Martin Glauer, I think both involved in the development of an ontology to represent energy scenarios. I'd contact also Daniel Huppmann (IIASA), to see how are they planning to get around this issue in the openentrance ( project.

If there is nothing that we can use, for energy products I think it makes sense to use the UN names as much as possible (

For activities, NACE is very vague, and as you point out it does not make any difference between electricity producers. NAICS provides some more detail

It is quite incredible that with the importance of the electricity sector there are no more standard names to call technologies...

Best, Miguel

Subject: [bonsai] Base nomenclature - theory into practice

Dear all-

PSI and LIST are part of a consortium of research groups trying to make prospective LCA better. To accomplish this, we have decided to create a standard implementation merging LCI databases with scenarios from energy system models or integrated assessment models. The software would be in Python and based on

As our aim is to support multiple systems, we need a reference base nomenclature for products and activities. As far as I can tell, we have invested a lot in building up various correspondence tables, but do not have a lot of development on a base nomenclature with scientific justification. (On the other hand, I think we have made a lot of progress in how to describe any such system.) I assume that such a system will start with a standard classification (e.g. GS1, NACE, etc.), and then use industry-specific classifications when more detail is needed (e.g. One important exception here is electricity, where I don't find a standard system that captures the level of detail we need (e.g. utility versus roof-top solar).

As Tomas N. and I are responsible for the technical foundation of this consortium, we have the chance to build it BONSAI-compatible from the beginning - but we need to make decisions soon on this critical issue.
Any input from the list would be greatly appreciated.
