RE: [EnergyPlus_Support] Internal gains





I have a look at your IDF.
------------------------
ScheduleTypeLimits,
any number, !- Name
, !- Lower Limit Value
, !- Upper Limit Value
; !- Numeric Type

Schedule:Compact,
PEOPLE, !- Name
any number, !- Schedule Type Limits Name
, !- Field 1
, !- Field 2
; !- Field 3
----------------------------------
 
The first schedule belongs to the Type Limits group.  The one for any number is misleading, as it has no other fields. 
 
If you look at the BasicsFiles folder of the EampleFiles folder, there are two tutorial examples.  You will see more limits and the use of compact schedules there.
 
THey are also available in the DataSet folder as Schedule.idf.
 
========
Each campact schedule is expended in the EPlus simulation to a full annual hourly data list before execution.  You may create such a file directly using the Schedule:File object using a spread sheet.
 
However, it is easier to use a compact schdule.  Remember that the compact schedule always starts from 1 Jan. at time 00:00 and must cover all the day types in each period, and must cover a full year to 31 Dec. 24:00..
 
For example:
 
Schedule:Compact,
OCCUPY-1, !- Name
Fraction, !- Schedule Type Limits Name
Through: 12/31, !- Field 1
For: WeekDays SummerDesignDay CustomDay1 CustomDay2, !- Field 2
Until: 8:00,0.0, !- Field 3
Until: 11:00,1.00, !- Field 5
Until: 12:00,0.80, !- Field 7
Until: 13:00,0.40, !- Field 9
Until: 14:00,0.80, !- Field 11
Until: 18:00,1.00, !- Field 13
Until: 19:00,0.50, !- Field 15
Until: 24:00,0.0, !- Field 17
For: Weekends WinterDesignDay Holiday, !- Field 19
Until: 24:00,0.0; !- Field 20
=================
 
Notice that the even fields are missing, because there are two data values on each line.(2 commas)
This schedule has an active group and a non active group.
 
Note that the through: specifies the period covered.  For:  daytype.
Until: is the ending hour:min. It is followed by a value.  The type of this value is defined as "fraction", which is defined in the Schedule Type Limits Name.  There are five or six standard ones.
 
 First starting time is 00:00 and is not shown.  The last Until: should always be 24:00.
 
In the above there there are two complete day schedules, therefore there are two 24:00 definition.
 
The name of the schedule is called "Occupy-1", because you cannot schedule "People" directly.
 
The maximum number of people is specified using the People object for each zone.
If you specify 10 person in a zone, the above schedule will show 10 person between 08:00 and 11:00.
Only 4 person during lunch time.  Not occupied during weekends.
 
It is more flexible to use a multiplier, so that the same schedule can be used for different zones with different number of people, but have a similar occupancy pattern.
 
======================
For your requirement, if the three days are consecutive, you need to use three perioeds.
 
If they are isolated days, then you may need N-A, A1, N-A, A2, N-A, A3, N-A periods.  N-A means non-actimve with one  Until:24:00, 0.0,  entry in each, the last one ends in a semicolon.  Because you may not know the day type, you may use  For:AllDays, to cover the 12 daytypes.
 
For people, you will also need to specify  Activity Level.  about 117 watts per person.  Clothng may also affect the heat load.
 
For simple heat insertion, it is simplar to use equipment with the same multiplyer as the people.
 
Other equipment would allow you to remove heat as well. (+ or = quencity)
