For this credit, what constitutes "unoccupied times" for lighting control systems?
We have a lighting control system that sweeps the building at 7pm to ensure lights in the building are off after-hours and every two hours thereafter. However, the lighting system does not sense when an office, conference room, or the restrooms are unoccupied and will not turn off the lights during technically occupied times of the day. Will this type of lighting system work, or does the system need to sense when every room is empty and switch off the lights?
Thanks for your feedback.

After reading the credit again, I think your existing lighting control panels will be fine. Although it mentions occupancy sensors as potential retrofit strategy for buildings without automatic lighting controls, the intent is to turn off the lights when the building is unoccupied. If the HVAC requirements are also met by a BMS sounds like your team is almost there.

Does your BAS control lighting in your offices, conference rooms, and restrooms generally, as in it shuts off all the lights at 7:00PM? Thanks!
