On a related note: There was a fire in Grand Island, NE last week that had 2 "sprinklered" paint booths. The building burned down, but the contents of the booths are salvageable.

The handbook material on the section I mentioned earlier (page 1007 AHJ FAQ) uses a paint booth as one of their examples for precisely this type of scenario with the exception that mine is completely outside the building. And that is my question - since this booth is completely outside the only attachment to the existing building is it's tap from the system riser. I think the case could be made to have a standalone calculation in this instance but wanted to see what the forum thinks.
