According to the beta update: The previous option for lighting control has been simplified to a single requirement for dimmable or multilevel lighting in occupied spaces.
What does it mean in practice? Do we still have to provide own lighting control for each individual occupant space, or is it enough that the whole occupied space (eg open plan office) has dimmable or multilevel lighting?
Our issue has always been to provide individual control for the open plan office individual occupant spaces, because the table lamps are not much needed for modern computer work. Would this beta update solve the issue?
Any thoughts? Thanks!

Hi Martina,
I'm assuming when you say the "beta" guide you are referring to v4.1? I just want to make sure other users understand that they are the same.
I don't have any inside knowledge of the change to the credit, but it does seem that you are correct and that the language about individual control has been removed and that multi-level/dimmability simply needs to be provided for an entire space (e.g. an entire open office space), rather than for individual users (via a desk lamp). I know in California there are requirements to break up large spaces into smaller groups which might be good practice, but doesn't seem to even be required here. I would agree with your interpretation and I'm guessing you could make the case with the LEED reviewer since there is no other information provided on compliance (at the moment).
Good luck!

Has this approach been confirmed? Has anybody submitted for this credit without tasklighting at open office workstations and achieved the credit? I have seen "space" interpreted differently and not neccessarily defined by walls. For example there any be several "spaces" within an open office: workstations, collaborative areas, etc. Under this interpretation, each space within an open office would need separate lighting controls (such as task lighting).

So it has been a few months since the last post on this thread, has confirmed the approach? I'm refining the lighting design on a project right now, looking at if we need to introduce tasking lighitng for some individual occupant open office workstation type spaces in order to achieve the credit. I'm looking at introducing the task lighting based on my history with the v4 form of the credit. I agree the way the v4.1 beta guide is written, it sounds like overhead dimmable or multi-level is all that is needed for an entire space, and thus the task lighting isn't needed.
