RE: [EnergyPlus_Support] Load Calculations





It should work with sizing (Sizing:Zone) periods from the weatherfile though those are not necessarily the peak days from the weather file.

You do not need to add a ficticious system -- that is taken care of by the sizing parameters.

Thank you Mahabir, Joe and Jean,
 
If I understood, this Zone Component Load Summary provide a similar rapport than DOE-2 LS-B with some differences listed by Joe. The first difference is the user-input design days but If we choose SizingPeriod:WeatherFileDaysâ?? instead â??SizingPeriod:DesignDayâ?? the peak days would be the same that LS-B report, will not be? Anyway, we have to add a fictitious system to work.
 
In my specific and actual case, I have to output the zones air temperatures to analyze the performances of a passive building. I donâ??t create any fictitious system so I canâ??t see the components loads. However, I can get a hourly report with the variable â??Zone Air Temperatureâ??. How energy plus calculates theses temperatures without calculate heat transfers by the walls and by the others zone surfaces? I didnâ??t set any indoor temperature setpoint to the building.
