After running my model, and clicking on Open Dview for detailed reports, i keep getting this about unit conversions. Any ideas why? i am unable to view my full results because of this

Thanks in advance

Based on the units, looks like a lighting issue - you might check your luminaire definitions (maybe a divide by zero situation)

Hello! I don’t have any luminarie definitions but I have light definitions, would I have to check my values? They’re all in Watts

Ok, are the light definitions applied to space types? You might also check the eplusout.err file in case there are any clues

Hello again, yes i do have light definitions applied to space types

When you tell DView to view outputs in IP units instead of SI units, it uses an internal list of unit conversions to convert the outputs. There is no "lum/W" unit conversion, so it gives that error. The only way to avoid the error would be to view the outputs in SI units.

What would the IP units equivalent of lum/W -- lum/(Btu/hr)? It's pretty trivial for someone to update DView to include a new unit conversion, though the OpenStudio team would have to package up a new version of DView with this change.

Note that you can file a bug report for DView here. There's at least one existing bug report related to unit conversions.

Hello, how do i view outputs in SI units? When i click No when it asks me if i want to view my Energy+ data in IP units, nothing happens and i still can't get results. I really need to solve this i don't know what to do :(

Maybe there is a more fundamental problem than the unit conversion error. Can you edit your original post and provide a link to your model? You can use Google Drive or Dropbox.
