A Green Proving Ground (GPG) study of occupant responsive lighting technology used in five federal buildings in the Pacific Rim Region showed energy savings over baseline conditions:

• 27% for spaces illuminated 12 hours a day, five days a week, with regular occupancy patterns,
• to 63%, for a call center illuminated 18 hours a day, 7 days a week. Payback for the call center was less than 7 years.
