Hi, I'm now using OpenStudio to input my space constructions. I have some radiant heating floors in contact with the ground.

I know I can define these constructions using "internal source constructions", and "F-factor ground floor constructions". Below is an example of how I define the construction set for space 101, when I opened the .idf, I noticed the floor is only specified using "Ground Contact Surface Constructions-floors" without anywhere showing the heated floor feature.

I'm struggling with how to input this complex floor construction, what is the correct way to do it in OS? Thank you in advance.
