Re: [EnergyPlus_Support] Problems with extracting hourly variables from EnergyPlus

I'm with Jerimia on this one:
Specify the output variable dictionary to output an .rdd file in IDF format.
Run the simulation to produce the rdd file (which will list all the possible output variables for your simulation). 
Open the rdd in a text editor, and copy paste the output variables that you want to include in your simulation and re-run.

The trickiest part are the definitions of the different outputs. You'll have to search the documentation for the ones which look interesting.

I'm doing some diagnostic simulations comparing EnergyPlus to another program (not DOE-2 :-)), and need to extract hourly variables for zone air temperature, inside surface temperature and heat fluxes through an interior wall.  I took some old IDFs from 6 years ago, ran them through the IDFVersionUpdater to get Version 8.0 IDFs, and used the resultant reporting for the zone air temperature, but I'm not getting anything in the output *.eso.

  Output:Variable,*,Site Outdoor Air Drybulb Temperature,Monthly;   < this works
  Output:Variable,*,Zone/Sys Air Temp,Hourly;                  < this does not work
  Output:Variable,*,Zone Air System Sensible Cooling Rate,Monthly;    < this works
  Output:Variable,*,Zone Air System Sensible Heating Rate,Monthly;   < this does not work

 Also, what is the syntax for specifying the heat flux for a particular surface ?  I tried this but it doesn't work:

    *,                       !- Key_Value
    HOUSE:AT-FLOOR2 Heat Flow,  !- Variable_Name
    Hourly;                  !- Reporting_Frequency
