I have a scenario where the core is offset, and is tight to the building envelope on one side. As a result, the egress path around the core on this side falls within the 15' perimeter. We have 2 fixtures in the egress path on this side that are tied to the building's emergency circuit and therefore are not on the same circuit as those tied to the daylighting controls. All other fixtures within the 15' perimeter zone are on daylighting controls.
We received the following review comment: "Not all lighting within the daylit zones is being controlled by the daylight responsive controls. Emergency lighting fixtures adjacent to 2917 Files are on a separate circuit that is not controlled by the lighting control system. Provide additional information confirming that 100% of lighting in daylit zones within 15’ of windows and under skylights is controlled by daylight responsive controls."
I have never had a problem with emergency lighting conflicting with credit compliance for daylight controls. Thoughts / recommendations?

If they are in a corridor that is not a regularly occupied space. Dimming is only required in regularly occupied daylit spaces.
