Depends on how you've set up your model but for example, in the sizing:zone, sizing:plant, and sizing:system objects you might have instructed the system to assume certain operational characteristics.  

Sizing:Zone,

    f1:airlineops216,        !- Zone or ZoneList Name

    SupplyAirTemperature,    !- Zone Cooling Design Supply Air Temperature Input Method

    12.8,                    !- Zone Cooling Design Supply Air Temperature {C}

    ,                        !- Zone Cooling Design Supply Air Temperature Difference {deltaC}

    SupplyAirTemperature,    !- Zone Heating Design Supply Air Temperature Input Method

    32.0,                    !- Zone Heating Design Supply Air Temperature {C}

...

Sizing:System,

    f0 ahu,                  !- AirLoop Name

    Sensible,                !- Type of Load to Size On

    AUTOSIZE,                !- Design Outdoor Air Flow Rate {m3/s}

    0.3000,                  !- Minimum System Air Flow Ratio

    7.0,                     !- Preheat Design Temperature {C}

    0.008,                   !- Preheat Design Humidity Ratio {kgWater/kgDryAir}

    12.8000,                 !- Precool Design Temperature {C}

    0.008,                   !- Precool Design Humidity Ratio {kgWater/kgDryAir}

    12.8000,                 !- Central Cooling Design Supply Air Temperature {C}

    16.7000,                 !- Central Heating Design Supply Air Temperature {C}

Sizing:Plant,

    Coil Hot Water Loop,     !- Plant or Condenser Loop Name

    Heating,                 !- Loop Type

    98.89,                   !- Design Loop Exit Temperature {C}

    11.11;                   !- Loop Design Temperature Difference {deltaC}
