Heating setpoint decreased by 2°C but the overall energy requirenment increses

Hello, I have concern about getting the cooling and humidification load increased drastically for the model by decreasing heating setpoint by 2°C.

I have just changed the class list - Shcedule:Compact from

Schedule:Compact, Htg-SetP-Sch, !- Name Temperature, !- Schedule Type Limits Name Through: 12/31, !- Field 1 For: Weekends HoliDay, !- Field 2 Until: 7:00, !- Field 3 16, !- Field 4 Until: 14:00, !- Field 5 16, !- Field 6 Until: 24:00, !- Field 7 16, !- Field 8 For: SummerDesignDay, !- Field 9 Until: 24:00, !- Field 10 16, !- Field 11 For: WinterDesignDay, !- Field 12 Until: 24:00, !- Field 13 21, !- Field 14 For: AllOtherDays, !- Field 15 Until: 5:00, !- Field 16 16, !- Field 17 Until: 6:00, !- Field 18 20, !- Field 19 Until: 20:00, !- Field 20 22, !- Field 21 Until: 24:00, !- Field 22 16; !- Field 23

to

Schedule:Compact, Htg-SetP-Sch, !- Name Temperature, !- Schedule Type Limits Name Through: 12/31, !- Field 1 For: Weekends HoliDay, !- Field 2 Until: 7:00, !- Field 3 14, !- Field 4 Until: 14:00, !- Field 5 14, !- Field 6 Until: 24:00, !- Field 7 14, !- Field 8 For: SummerDesignDay, !- Field 9 Until: 24:00, !- Field 10 14, !- Field 11 For: WinterDesignDay, !- Field 12 Until: 24:00, !- Field 13 19, !- Field 14 For: AllOtherDays, !- Field 15 Until: 5:00, !- Field 16 14, !- Field 17 Until: 6:00, !- Field 18 18, !- Field 19 Until: 20:00, !- Field 20 20, !- Field 21 Until: 24:00, !- Field 22 14; !- Field 23

but instead of decresing energy demand it increased because of the sharp rise in cooling and humidifcation demand, even though rest of the setpoints have not changed.

Why is the increased cooling load ?
