I like this credit, but I don't think the language is clear. The beginning of the credit tells me that I need to have at least one main stair. Ok - understood. Now, the second part gives descriptions of other requirements, but it does not say whether this is required of all stairs, some of the stairs, or just that main stair. I believe my project can meet this if it applies to that main stair, but it may not apply to all of the other 4 stairs in this small building or if it applies to exterior stairs.
Has anyone had any experience with submitting this to USGBC? Does anyone have suggestions for the documentation?
