Could extra HB face be part of HB model with rooms included?

Hello everyone,

I have a modeling question for energy simulation. In HB model component, I already have an input of honeybee room (A). However, there is a large ceiling space (B) above the room, and I don’t want to ignore it during simulation. The normal way is to model the ceiling space as another thermal zone. But I only want to calculate the EUI of A. So, I think it may be OK to model B as HB faces, and connect them to HB model. I don’t know if it is the right step.

Thanks a lot.

For the HB faces of ceiling space B, I have removed the bottom side of B.
