I'm filling out the Table IEQc9-1 and it asks me for a STC rating for the ceiling assembly. I set the space "adjacent to assembly" to "outdoors " because it is only a 1-story building. How do I find out how to calculate the STC of my roof/ceiling assembly? Thanks.

I think an acoustical consultant is probably your best bet for a roof/ceiling assembly STC rating. You might be able to find something similar in the UL design guide, but I usually don't recommend UL guides for STC ratings because they're often not very accurate.
