INTERIOR LIGHTING IN OPEN OFFICES

I have the same question! Frustrating that they use the term "occupant spaces" without defining it. Do they mean each cubicle in an open office environment is an "occupant space" or that the entire "occupant space," meaning the entire open office area, has to have dimmable or multilevel lighting control? The v4.1 form and the beta v4.1 guide offer no clarity on this point. After 13 years of certifying building/spaces under LEED its this type of ambiguity and failure to anticipate the most basic questions that makes LEED overly complicated to use! 

I had open office spaces/labs/collaboration spaces with multilevel lighting (on/of/midlevel switches) for the whole space without a need of individual lighting controls (no task lighting) accepted by reviewers.

That's interesting, Kai.  Because for one of the LEED v4 projects I worked on, I was denied one point under lighting controls unless I provide individual dimmable desk lamps for the individual workstations in an open office.  Did you have better luck because your project was under LEED v4.1 or did you provide special circumstances that providing individual dimmable lamps would interfere with the primary function of the occupants in those spaces?
