Zone multiplier doesn't impact Output:Variable value for lights and equipment

[aaron-boranian]

Issue overview

In a test, I modified the 5ZoneAirCooled.idf example file to apply a multiplier of 5 to the SPACE1-1 Zone object, then renamed the model to 5ZoneAirCooled-test.idf. After running a simulation and comparing results across the generated ESOs for both IDFs, InteriorLights:Electricity and InteriorEquipment:Electricity output meters change as expected but Zone Lights Electric Energy and ZoneElectric Equipment Electric Energy output variables remain the same. Refer to table below for annual results for SPACE1-1.

IDF	Interior Lights Meter [MBtu]	Interior Equipment Meter [MBtu]	Lights Variable [MBtu]	Equipment Variable [MBtu]
5ZoneAirCooled	16.262	95.479	16.262	95.479
5ZoneAirCooled-test	81.311	477.398	16.262	95.479

I tested individual Lights Electric Energy output variables as well and got the same results as the cumulative Zone Lights Electric Energy output variables.

There are similar closed issues on Github from previous CRs: #745 for zone multiplier for lights and equipment and #1137 and zonelist multipliers for lights and equipment. These may have addressed applying multipliers to meters and report variables, but not output variables viewed in ESO and CSV files.

If people want to recreate the test, I have attached the two input files (change the extension from .txt to .idf)
5ZoneAirCooled-test.txt
5ZoneAirCooled.txt

@aaron-boranian This is the way it's designed to be. Zone-level outputs should be unmultiplied - they are per instance of the zone.
