Hello all - We have a CI project that has "Occupancy Sensors" around the perimeter of the space within 15' of the windows. The occupancy sensors have a "Low Light" option that controls the sensors to turn lights ON automatically ONLY in low ambient light conditions (10 Lux/1fc); the sensor turns lights OFF automatically when occupants aren't detected. Does this meet the requirements for daylight controls/sensors under Option A (even though the manufacturer's cutsheet calls the device an "Occupancy Sensor" in lieu of a "Daylight Sensor"?

Maybe. It does sound like a daylighting control as defined in the credit language. You will need to address the issue of the control "option". Obviously this option must be engaged. It must also be permanently set to that option and changing it cannot be accessible to the occupants.

Thanks for the quick reply Marcus - we will look into how to permanently set it to the "Low Light" option and let you know if anything comes out of the LEED review.
