Is there any way to add an electronic light source to LBT1.4.0?

I just wanted to say that I was able to include lights from IES files in a LBT Radiance simulation but it involves a huge amount of manual work such that I really don’t think that it’s worth it to leave Legacy for this right now. I really just need to sit down for a couple of days and write out a couple of classes and components to automate this. I don’t think I’ll get the opportunity to do so for another week or two so I would recommend sticking to Legacy if you really need this right now.

However, if you are feeling particularly motivated, here is the very manual workflow that I used to include IES files in the LBT simulation:

  1. Use the “HB Model To Rad Folder” component to write out a Radiance folder of a Honeybee model.
  2. Use the Legacy IES components to convert the IES file into appropriate Radiance files and copy them into the scene folder of the Radiance Model folder.
  3. Open all 3 of the Radiance files generated by the Legacy components in a text editor and change all file paths in the files to be relative to the root of the model folder.
  4. Plug the Radiance folder into the recipe.

I will post back here if I manage to get parts of this automated. The toughest part of the manual workflow right now is generating the Radiance files from the IES file and editing the file paths to be relative to the root of the model folder so I’ll see if I can tackle that first in a week or so.
