[EnergyPlus_Support] Question about "Zone List Multiplier"?

["i50330513" <50330513@xxxxxxxxxxx>]

I make good use of `EnergyPlus' program to predict the energy 
performance of a commercial building which is a 40-story building. I 
had already simulated the 40-story building.

In order to reduce the amount of input of the identical floors and 
have a shorter computational time, Zone List Multiplier field in the 
Zone Group object are used to multiply from 1st to 38th floors. 
However, after simulation of the building with this Multiplier 
field, I found that the total electricity use (Electricity:Facility) 
and the plant loop cooling demand of the building are much less than 
that of the building without using the field of Zone List 
Multiplier. 

Is there any input error in the program? The Zone Group object is 
shown as follows. You can see that the Zone List multiplier is set 
to 38 in the 1st FLOOR. Does it mean that the 1st FLOOR is 
multiplied by 38? If yes, why the total electricity and the cooling 
loads are much less than that of the building without the use of 
Zone List multiplier field.  

---------------------------------------------------------
ZONE GROUP,
    GF FLOOR,			!- Zone Group Name
    GF FLOOR LIST,		!- Zone List Name
    1;				!- Zone List Multiplier

ZONE GROUP,
    1st FLOOR,			!- Zone Group Name
    1st FLOOR LIST,		!- Zone List Name
    38;				!- Zone List Multiplier

ZONE GROUP,
    RF FLOOR,			!- Zone Group Name
    RF LIST,			!- Zone List Name
    1;				!- Zone List Multiplier
---------------------------------------------------------

I hope you make some recommendation for me. Thanks for your 
attention.
