Wireless Measurement Control

• Objective
• Study how small multi-modal sensing technology
  could affect the operation of buildings

• Motivation
• Wireless (50-90 of sensor cost due to wiring)
• Small, could be embedded or attached to
  furniture, ceiling tiles, walls (smart dust)
• Self locating, could also be used to keep track
  of furniture and equipment
• Low cost (gt5 possible)

Wireless Measurement Control

• Issues
• Power sources
• What to do with additional data points?
• Method
• Collaboration with other UCB research groups
• Sensor development
• Computer simulations of sensor networks
• Demonstration projects on UCB campus

Mixed-mode Buildings

• Field Study Findings
• Buildings energy efficient
• Occupants prefer ventilation and IAQ over
  conventional systems
• Occupants preferred window control to HVAC
  control
• Engineers very concerned about how to control the
  HVAC systems
• Potential to control via wireless sensors in
  windows and space
