I have looked at this question multiple times and I can’t wrap my head around the Black Spectacle correct answer of 93 people for the occupancy.
here is my calculation per table 1004.1.2. in the IBC:
1,000 s.f. coffee area…700 s.f. / 5 = 140 ( standing - assembly)
300 s.f. / 15 = 20 (concentrated - assembly)
1,000 s.f. reading room 700 s.f. / 50 =14 (reading rooms - Library)
300 s.f. / 100 = 3 (stack area - Library)
2,000 s.f. Open office…2000 s.f. / 100 = 20 (Business)
333.3 s.f. Office 1…333.3 s.f./100 = 4 (Business)
333.3 s.f. Office 2…333.3 s.f./100 =4 (Business)
333.3 s.f. Office 3…333.3 s.f./100 = 4 (Business)
my total is 209 people!!!
Here are my questions:
- why is black spectacle not taking into account the 300 s.f. of the table are in the cafeteria?
- why is black spectacle using a factor of 15 in the 700 s.f. coffee area that it is open?
- why is black spectacle not taking into account the 300 s.f. of the stack area in the reading?
Can any one help me understand? I’m really confused, I was the life safety person for 8 years at my previews company, so I thou I knew how to work these numbers pretty good, but apparently I’m missing something here
