OSM Electric Equipment Multiplier Interpreting to IDF

asked 2018-07-06 13:00:05 -0500

updated 2018-07-11 13:16:24 -0500

I am now working with internal electric equipment load, and when I converted the osm file to idf, I could not find the multiplier information anywhere in IDF. I have changed my system in IDF and need to run simulation with this IDF, but I also need to change the equipment multiplier. Does anyone know where it was and how osm interpreted equipment multiplier to idf ?

It appears to be applied to the Design Level, Watts per Zone Floor Area, or Watts per Person, depending on which one exists. I figured it out by looking at the OpenStudio source code.

But the design level(watts) in IDF is not scaled by the multiplier (1700 as is shown in the picture)

Are you sure you're looking at the right objects? You're showing Electric Equipment 2 in the OSM while Electric Equipment 1 in the IDF.

It might help to include the ElectricEquipmentDefinition object from your OSM so we can see its design level.

I am sorry, I just checked the value, yes you're right!! It does scale the value, my mistake. Yeah, the picture is just showing the structures of the block in different formats. Anyway, thank you very much!! It's really helpful!
