Hi All,
I am trying to determine the cause of a discrepancy between "Misc Equip"
in a baseline and proposed model.
I've already done a text file comparison on the .INP files, but have not
yet identified the cause.
Could someone please list any other various energy uses that could be
included in this category (other than the equipment/plug loads)?
So far I've determined that process loads on the Chilled water loop are
reported under Misc. Equip. - any other ideas of items to look for?
Thanks very much for any suggestions.
Kind Regards,
Molly Curtz, P.E.
One thing I typically find is that values were not updated between the
ASHRAE baseline and the proposed when something new is learned about the
project, but an INP review should have caught that. Do you use global
parameters for these W/sqft inputs? I also find that these are sometimes
off or overwritten and that the pink global values looks so much like
the red values that I miss a cell that's off when doing a side-by-side
comparison of the spreadsheet views of each model.
Lastly I would recommend copying all of the equipment schedules from
the proposed INP file and pasting them over the baseline INP schedules,
in case you accidentally modified something in there.
Good luck

There is a description of end use categorizations included in the
following .pdf file:
Help -> Tutorials & Reference -> Detailed Simulation Reports Summary.pdf
The last 3 pages list what energy is grouped into the energy end use
categories.
Hope this helps.

HI Molly,
Another place you may want to check is under the utilitties tab - under the electric meter tab - under direct loads. Sometimes we enter information in the wizard and that becomes a part of this input.
Hope all is well at your end.
cheers

Brian,
I'm not seeing this on the Help menu in eQuest. I'm still running
version 3.60, are you running a newer version?
Thanks,

All,
Thanks for your input. I found looking at the LS-K reports - in fact I did text file comparisons of the LS-K sections of the .SIM reports for the two files - helped to track down the inadvertent discrepancies in the equipment loads I'd assigned to the spaces. Those discrepancies, combined with the CHW loop process load (which was different in the two runs do to the plant efficiency differences) accounted for the different Misc. Equip. end use energy.
I couldn't find the .PDF file that Brian Fountain mentioned - is this because I'm not in the most current version of eQuest? (I'm running 3.60)
Thanks for the help.
Kind Regards,

Thanks Nikola!
