I'm somewhat surprised by the lack of posts for this topic.  We found it matched up nicely with our OPR and desire for appropriate daylighting throughout the project.  We actually fell just under the 75% threshold for the main Daylight credit, but the threshold for the nonregularly occupied spaces were much more achievable, possibly too easily?  We achieved 42% with a 20% threshold.

Does anyone else have experience with this credit?
