[Equest-users] Electricity consumption mismatch between model and bill

[Inga Goebel]

Hello,

I am currently struggling with a problem concerning the electricity consumption of the building I modeled in eQuest. eQuest predicts a way higher electricity consumption than it actually was billed for by the power provider. eQuest predicts a usage of about 330 MWh a year and the actual bills were at 73MWh for a year. Being sure that the power provider doesn't give away free electricity, I am currently trying to figure out where I made a mistake.

One possible problem could be, that I included all the mechanicals (like pumps, AHU, fan, unit heater, boiler,...) in the plug loads (misc. equipment), which I read later, I should not do. But I am also not able to find where I can correct it without going back to the wizard and losing all my changes made in detailed mode.  Now it is only shown as equipment load which (if I understand correctly) includes my plug loads and also the electricity consumption calculated by eQuest of the HVAC system. So is the consumption of the HVAC system accounted for twice? Since I only want to redo my plug loads, how can I do that without interfering with the eQuest calculation of the HVAC electricity usage? Any help with that?

Also, these loads should not be a majority of the building and the overall consumption will still be too high (at least that's my guess). Anyone ever had the same problem?
Lights consumption is about correct.

Thank you for your help.
