In LEED V4.1 Interior lighting credit, Lighting control. The guide states that we have to "Provide dimmable or multilevel lighting for 90% of occupant spaces." Does it mean that in open office spaces it is now enough to provide multilevel lighting (on/of/midlevel switches) for the whole space without a need of individual lighting controls? Or should individual occupants be provided with access to dimming control through app or an integrated system ?

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!
