Should decorative lighting be included to Options B&C ? This decorative lighting is not within 15ft of windows and is independently controlled by occupancy sensors.
Connected lighting load include exterior lighting?

Vacancy sensors in place of occupancy sensors
CI-2009 EAc1.2:Optimize Energy Performance—Lighting Controlsposted by Heather Dorer on
Can vacancy sensors be used in place of occupancy sensors in appropriate spaces? Vacancy sensors, like occupancy sensors, will turn the lights off when the room is deemed vacant.
