NREL IPOS Project

Robust hardware/software prototype using image processing technology to:

  • Identify occupancy regardless of motion

(eliminate false positives/negatives)

  • Classify occupancy by capturing additional

information about a scene (such as number and position of occupants and activity level)

  • Communicate with BAS and EMS using a

standardized protocol (BACnet)

slide-16
SLIDE 16

E3 E3T

Energy Efficiency Emerging Technologies

NREL IPOS Project

  • Commonly used motion detectors are only

surrogates for occupancy measurement

  • Image processing to identify occupancy
  • Commodity hardware produced for cell phone

industry

  • Small form factor
  • Low cost
  • Low power consumption
