I cant see ideal air load in output variables or BCL

edit

If you're successfully running OpenStudio models with zones having the "Turn On Ideal Air Loads" option, open the (EnergyPlus-generated) run/.rdd file and search (CMD-F) for "ideal". You should get around 60 hits, e.g.:

Output:Variable,*,Zone Ideal Loads Supply Air Sensible Heating Energy,hourly; !- HVAC Sum [J]
Output:Variable,*,Zone Ideal Loads Supply Air Latent Heating Energy,hourly; !- HVAC Sum [J]
Output:Variable,*,Zone Ideal Loads Supply Air Total Heating Energy,hourly; !- HVAC Sum [J]

If you're not able to add these directly in OpenStudio Application's Output Variables tab, open the .osm file using a text editor, and add them directly, e.g.:

OS:Output:Variable,
  {1e353f85-11a8-4495-a2ed-be20a1a827a3},              !- Handle
  Output Variable 3,                                   !- Name
  *,                                                   !- Key Value
  Zone Ideal Loads Supply Air Sensible Heating Energy, !- Variable Name
  Hourly;                                              !- Reporting Frequency

Make sure the handle is unique (change one or more characters if needed). Tested - works. Should do the trick.
