I'm working on a CI 2009 platinum-seeking restaurant, shooting for all three points in this credit. Here's the catch: it doesn't make sense for us to put occupancy sensors in the dining room, bar, and kitchen, as these areas will be occupied during all business hours, and even if a space cleared out we would not want the lights to turn off for business purposes. Can we interpret the 75% requirement to apply only to non regularly occupied spaces, or is this point only attainable if we add unusable sensors? Thanks very much!
