[EnergyPlus_Support] Heating Load zero

["harshana.thimmanna" <harshana.thimmanna@xxxxxxxxx>]

Hi all,

I am a research assistant at IDL, Boise. I am new to the job and presently working on the energy plus simulation. During the simulation, i ran into many errors.I appreciate if any one help me figure things out.The problem is as follows:

The building has various zones and the error occurred in the zones which do not have any exterior contact(surrounded by other zones).The HVAC system is VAV and there is zero heating load in the above mentioned zones. Below attached is the error message,

** Warning ** Calculated design heating load for zone=L1ESTAIR is zero.
   **   ~~~   ** Check Sizing:Zone and ZoneControl:Thermostat inputs.

Could anyone help me as to how to get heating load in those zones.the VAV system and thermostat inputs described is

HVACTemplate:Zone:VAV,
    L1EStair,          !- Zone Name
    VAV1,         !- Air Handling System Name

     Clg-SetP-Sch,          !- Heating Setpoint Schedule
     ;                      !- Constant Cooling Setpoint {C}

with a normal schedule as in examples.
I really appreciate the help.
Thanks
