I'm designing a 3-story life science lab building (B occupancy) that will be constructed of CLT. It's not a big footprint (18,000 SF) and a Type V-B gives me the height, stories, and area I need. There are benefits to not using a Type IV (mostly fire ratings) but are there any downsides to using V-B?
For instance - The required Fire Flow (CFC appendix B) for a type V-B is greater than other types. If Fire Flow is high enough you might need a water tank. But on this small of a building, the fire flow requirement (with allowed reduction) isn't any more that any other type.
Can you think of anything else, like fire flow, that selecting a Type V-B "costs" me? If I don't need it for height or area, what benefit is there to calling my building a type IV?
Thanks for any insights!
