I am working on an office building that has overhead lighting that is controlled based on occupancy sensors. The fixtures are grouped per 3,6 meters and there is no manual override. Additionally we include task lighting on the desks with on/midlevel/off possibilities. Is this sufficient control to meet the credit requirements? Or do we also have to include a manual override for the overhead lighting in addition to the tasklighting to meet the full "off" requirement?
And suppose we include the manual override for the overhead lighting, is it OK if this is grouped per 3,6 meters (possibly including mutiple workstation?In my opinion is does not make sense to have individual on/off switches for the overhead lighting in an open office environment when there are tasklights that provide sufficient individual control.
