Hello everyone ! I just started using EnergyPlus one month ago and I'm struggling a bit. I'm trying to run a simulation but I have this warning :

 ** Warning ** GetInternalHeatGains: People="ROOM PEOPLE", Activity Level Schedule Name values
**   ~~~   ** fall outside typical range [70,1000] W/person for Thermal Comfort Reporting.
**   ~~~   ** Odd comfort values may result; Schedule="OFFICE OCCUPANCY 2".
**   ~~~   ** Entered min/max range=[0.0,] W/person.1.0

I used the same schedules from the exemple AdultCenter2 given in the examples files.

Is there someone that has already had this kind of warning ? I tried to change the number of people and change the schedule but I can't solve the problem.

Thank you in advance for your help ! Samuel

Not sure how the people objects are set up in your input file so I will try to explain the example file inputs. In the example file AdultEducationCenter.idf the People object and the corresponding Activity Level Schedule are shown below. The activity level is set at 131.8 which is within the range of 70-1000 shown in the warning message you show in your question. However, your warning message also mentions OFFICE OCCUPANCY 2 as the schedule being used. So are you sure you are using the correct schedule for "activity level"? Changing the number of people will not get rid of this warning, you must enter an activity level (e.g., seated, walking, running, excercising, etc) that is within the range of 70-1000.

Thank you very much for your answer ! I added a schedule named "Activity Level" that I forgot to add in the section "Schedule:Compact". And I putted the parameters from AdultEducationCenter.idf. into it. Then I linked this schedule with the section "People" and it worked! Thank you for your help and your reactivity !
