What egress capacity factor do you use to calculate stairways? In practice, I've always used 0.3 in. per occupant. Some study material I've been referencing is saying to take Exception 1 and use a 0.2 in. per occupant egress capacity factor when the building is Sprinklered. However, as I understand 2015 IBC, Exception 1 only applies if there is a sprinkler system *and* an emergency/voice alarm communication system. So now I'm just confused! Thoughts?
