Re: [EnergyPlus_Support] Inability to output data for days other than Design Day



Not sure if it was called this in v7, but looking at v8, you need to tell EnergyPlus to run the simulation for weather file run periods.. that's in the SimulationControl object.
 
Often, it will look like this:
 
SimulationControl,
    Yes,                     !- Do Zone Sizing Calculation
    Yes,                     !- Do System Sizing Calculation
    Yes,                     !- Do Plant Sizing Calculation
    Yes,                     !- Run Simulation for Sizing Periods
    No;                      !- Run Simulation for Weather File Run Periods
 
In that case, you'll get sizing calcs and simulation results for ONLY the sizing periods. If you just want simulation results for the run period (and autosized equipment), you'll need to change it to:
 
SimulationControl,
    Yes,                     !- Do Zone Sizing Calculation
    Yes,                     !- Do System Sizing Calculation
    Yes,                     !- Do Plant Sizing Calculation
    No,                      !- Run Simulation for Sizing Periods
    Yes;                     !- Run Simulation for Weather File Run Periods

Hi there,


I'm very new to EnergyPlus and am trying to do a very basic model of a one-zone house for the months of February and July, profiled four times an hour, with outputs such as temperature, sensible heating/cooling etc. For some reason, however, I can only get the program to produce hourly data for my two designated Design Days in February and July (rather than for both whole months).

I am using Version 7.0 of EnergyPlus. I have defined the Timestep to be 4, the RunPeriod to be for the months of February and July and I have also designed two Design Days as 21 February and 21 July.

I just can't figure out why it will only produce data for the Design Days. Is there anywhere else I need to tell the program that it should be profiling for the RunPeriod? I'm also not really sure why I need the Design Days designated, but the program won't run without these definitions.

If anyone has any ideas to help me, I would really appreciate it!

Thanks very much,
Dave
