Cooling and Heating Coils only Assigned to One Air Loop

#1

Using the HVAC System Type 7 Template fairly unaltered except for the addition of a return plenum.

I have 12 floors in my building, so it is creating 12 air loops. When I try to run I get this error:

Program Version,EnergyPlus, Version 8.9.0-eba93e8e1b, YMD=2019.04.11 15:55,

Looking inside of the OS file, I see that the cooling and heating coils on the supply equipment are missing, except for the twelfth and final loop:

Any idea why the coils are not translating to all but one of the air loops?

Since you need 12 airloops, and I think you only have one CoilHeatingWater on the supply side, this is the issue.


You can Duplicate the same amount of CoilHeatingWater on the supply side and match the data structure as same as the demand side.
