If you report Fan Electric Power, or System Node Mass Flow Rate, you'll see that the air handler is not operating on the design days. That leads to the airloop AvailabilityManager or the schedule in the supply fan object. The schedule referenced by the fan object is
Schedule:Constant,
Always On Discrete, !- Name
OnOff, !- Schedule Type Limits Name
1; !- Hourly Value
No problem there. The schedule reference by the AvailabilityManager:Scheduled is
Schedule:Compact,
On24/7/Weekdays, !- Name
OnOff, !- Schedule Type Limits Name
Through: 12/31, !- Field 1
For: Weekdays, !- Field 2
Until: 24:00, !- Field 3
1, !- Field 4
For: AllOtherDays, !- Field 5
Until: 24:00, !- Field 6
0; !- Field 7
The day types in the design days are WinterDesignDay and SummerDesignDay, so the above schedule is off on those days. Change "For: Weekdays" to "For: Weekdays WinterDesignDay SummerDesignDay," and the system will run.
