Question-and-Answer Resource for the Building Energy Modeling Community

The short answer is yes. The long answer is that "energy transfer" data is organized on system, zone, facility, building, heating, or cooling meters.
Energy transfer meters refer to air or water energy transfer. The electric meters report electrical energy use. Each meter is described in the meter definition file (mtd). At the top of this file is a list of all energy and electricity report variables and on which meters those variables are reported. For example one energy transfer variable shows the multiple meters where this energy data is stored:
Meters for 306,SPACE1-1:Zone Air System Sensible Heating Energy [J]
OnMeter=EnergyTransfer:Facility [J]
OnMeter=EnergyTransfer:Building [J]
OnMeter=EnergyTransfer:Zone:SPACE1-1 [J]
OnMeter=Heating:EnergyTransfer [J]
OnMeter=Heating:EnergyTransfer:Zone:SPACE1-1 [J]
In the above example, the Zone Air System Sensible Heating Energy is included on meter=Heating:EnergyTransfer as well as four other meters. One could infer that all zones would be included on the same heating energy transfer meter and finding this specific meter in the mtd shows that the Heating:EnergyTransfer meter contains information for each zone.
For Meter=Heating:EnergyTransfer [J], ResourceType=EnergyTransfer, EndUse=Heating, contents are:
PLENUM-1:Zone Air System Sensible Heating Energy

SPACE2-1:Zone Air System Sensible Heating Energy
SPACE3-1:Zone Air System Sensible Heating Energy
SPACE4-1:Zone Air System Sensible Heating Energy
SPACE5-1:Zone Air System Sensible Heating Energy
All energy data contained on a single meter is summarized at the bottom of the file. In this example, the energy transfer data for SPACE1-1:
For Meter=EnergyTransfer:Zone:SPACE1-1 [J], ResourceType=EnergyTransfer, Group=Zone, contents are:

Zone Air System Sensible Heating Energy [J]
This output variable represents the sensible heating energy in Joules that is actually supplied
by the system to that zone for the timestep reported. This is the sensible heating rate multiplied
by the simulation timestep. This is calculated and reported from the Correct step in the Zone
Predictor-Corrector module. . This field is not multiplied by zone or group multipliers. Zone Air
System Sensible Heating (and Cooling) Energy (and Rate) all report the heating or cooling
delivered by the HVAC system to a zone. These values are calculated by multiplying the supply
air mass flow rate by the difference between the supply air temperature and the zone air
temperature. This does not always indicate the operation of heating or cooling coils. For example,
cooling will be reported if the supply air is cooled due to the introduction of outside air, even
if all coils are off. Note that these variables are calculated at the system timestep. When
reported at the "detailed" reporting frequency, these variable will never show heating and
cooling both in the same system timestep. If reported at a frequency less than "Detailed"
(for example, Hourly) values may appear in both the heating and cooling variable for the
same hour if the system cooled the zone for part of the reporting period and heated the
zone for another part of the reporting period.
