Is anyone aware of a CIR or received approval for using vacancy lighting sensors on a LEED project. Meaning the sensor works like an occupancy sensor but does not turn lights on until the user flips the switch. Then the lights automatically turn off after sensing no occupancy for a time. If so, what is the approved percentage deduction off of light power density. I was assuming an additional 10% over regular occupancy sensors but have been told the savings could really be a lot higher than that. Thanks.
