Good job, @TrevorFedyna ! I would say that you’ve effectively converted the sample file over to LBT. There’s only one other suggestion that I have for a case like this where the dynamically-generated unique IDs for the rooms become more annoying than helpful.
You can use the HB Set Identifier component to overwrite the ID of the Room to something constant, which you can reference within your additional IDF String:
1.4.0_cooling_tower_CWM.gh (105.5 KB)
Otherwise, looks good. I know that there are often typos in E+ docs so you might have found one here that could be reported to the E+ Github:
