There has been some confusion around this issue with LEED users sharing feedback that LEED reviewers are requiring a high level of controllability with both dual switching and dimming for every multi-occupant space. The LEED Reference Guide simply states that you must “provide lighting system controls for all shared multi-occupant spaces to enable adjustments that meet group needs and preferences.”
While it is best to consider the needs of everyone in the space, this does not necessarily mean that you need to have dimmers, multi-switched lighting, or occupancy sensors. As stated on page 522 of the LEED Reference Guide, switched receptacles are appropriate to provide a variety of lighting options within the space; however, the corresponding lighting fixture that will be plugged into the receptacle must also be provided if the control is included in the count of controls for individual workstations or multi-occupant spaces.
