Lighting in unconditioned exterior concourses

Since it is a covered space I would tend to treat it as interior corridor. None of the exterior lighting includes spaces that are substantially covered. By way of example take a freestanding parking garage. The parking on the roof is considered exterior. The parking on the decks below are considered interior. These concourses are more like the lower parking decks than they are like an exterior plaza or walkway.

Hello everyone, I want to reopen this thread because I have a similar question regarding lighting, and how to consider some luminaries.

Currently, I am working on a 4 floor residential project where open corridors connect the entrance doors for the dwelling units. However, I am unsure if the lighting in those corridors must be considered exterior lighting (walkway, main entrance, or entry canopy), since the above corridors would function as roofs for the below corridors, for context the corridors have a width between 4 ft and 7 ft, and they are open to the exterior at the extremes.

To me, my first instinct is to consider it exterior lighting, but they could also be considered interior if we were to compare them to the open parking with a roof above situation. What do you think?

Thanks!

I think the same logic I applied above still holds true. The spaces you describe are even more covered than the concourses in the previous example. This sounds way closer to a corridor than it does to any of the outdoor lighting space types you mention.

Another way to view this issue is to apply the "conservative" approach. Essentially which way produces the least amount of savings? This can often be used as justification for a selection you made that is not exactly clear in the standard.
