Re: [EnergyPlus_Support] electric energy consumptions do not line up

["Michael J. Witte" <mjwitte@xxxxxxxx>]

Are you using zone multipliers?  Or do you have multiple electric equipment 
objects in the same zone?

There is a known bug related to multiple electric equipment objects in version 
1.1.1 (CR 6036):

If there are multiple ELECTRIC EQUIPMENT objects in the same zone on the same 
end-use, the report variable for "Catnn Electric Eq-Consumption" shows up 
multiple times and the energy is overcounted on the meters.  For example, if 3 
objects in ZONE1 are on Category 01, there will be three occurences of 
"ZONE1:Cat01 Electric Eq-Consumption[J]" in the eso file, and it shows three 
times on each applicable meter in the mtd file.  Each occurence will report the 
total consumption for all three objects.  The meters will incorrectly total all 
three occurences of these, so for 3 objects, the meters will report 3 times the 
correct value.

This problem has been fixed for the next release, version 1.2.0.  You can check 
the meter details (mtd) output file to see exactly what is being reported on 
each meter.  If you are using multiple electric equipment objects in the same 
zone, you can work around this problem by setting each one to a different end 
use category.
