Which individual occupant lighting control meets the requirements of Indoor Environmental Quality Credit, Interior Lighting?

The Indoor Environmental Quality Credit, Interior Lighting, requires the project team to provide

individual occupant lighting control for at least 90% of the individual occupant spaces, or at least 50%

of the shared multi-occupant spaces. The lighting control must enable occupants to adjust the

lighting to suit their individual tasks and p

, and must have at least three lighting levels,

excluding off1. Therefore, a three level (on, 25%, off) lighting control meets the requirements of this

credit, while a two level (on, off) lighting control does not. A three level (on, 50%, off) or a three level

(on, 75%, off) lighting control may also meet the requirements, depending on the lighting power

density and the daylight availability in the space2.
