Hello everyone. I am trying to determine the PMV and cooling/heating energy of my first test project on EnergyPlus. However, I am experiencing four major challenges;

I do get an error that says “* Severe * ProcessScheduleInput: Schedule="OFFICE_ACTIVITY_SCHEDULE_01" has values outside its Schedule Type (ACTIVITYLEVEL) range * ~~~ * Minimum should be >=72.000 and Maximum should be <=909.000. However, in my activity settings, the values I set were 72 for periods without activity and 132 for periods of activity.
My PMV is mainly around -0.5 all year round which seems unrealistic.
While trying to improve my PMV, my current cooling energy became 0.
My electricity result is also constant.

Does anyone, have an idea how I can improve the model and correct these errors? I have also attached the idf to this question. I will be glad to receive comments that will point me in the right direction.

Thank you for the help.

If you modify the "OFFICE_ACTIVITY_SCHEDULE_01" from:

Schedule:Compact,
    Office_Activity_Schedule_01,  !- Name
    ActivityLevel,           !- Schedule Type Limits Name
    Through: 12/31,          !- Field 1
    For: Weekdays,           !- Field 2
    Until: 08:00,            !- Field 3
    72,                      !- Field 4
    Until: 18:00,            !- Field 5
    132,                     !- Field 6
    Until: 24:00,            !- Field 7
    72,                      !- Field 8
    For: Weekends,           !- Field 9
    Until: 24:00,            !- Field 10
    72;                      !- Field 11

... to (note the "AllOtherDays" entry) :

Schedule:Compact,
    Office_Activity_Schedule_01,  !- Name
    ActivityLevel,           !- Schedule Type Limits Name
    Through: 12/31,          !- Field 1
    For: Weekdays,           !- Field 2
    Until: 08:00,            !- Field 3
    72,                      !- Field 4
    Until: 18:00,            !- Field 5
    132,                     !- Field 6
    Until: 24:00,            !- Field 7
    72,                      !- Field 8
    For: AllOtherDays,       !- Field 2
    Until: 24:00,            !- Field 3
    72;                      !- Field 4

... you should no longer see a related (severe) error in the eplusout.err file.

Once that's fixed, EnergyPlus will then sequentially trip over other severe errors (e.g. on invalid thermostat definitions). I suggest you fix all of these severe errors, one by one, before attacking (most) warnings. Only then should you really start paying attention to inconsistencies in reported results. My 2-cents.

Thank you once again Denis. Your solution solved the "OFFICE_ACTIVITY_SCHEDULE_01" issue. I will do well to work on the other errors and warning as suggested.

Thank you.
