  1. What’s Really Happening?

  2. Building Smart, Building Green… • Smart building technologies can improve buildings’ energy efficiency and indoor environmental quality.

  3. Definitions Smart Building: A building that provides a productive and cost-effective environment through optimization of its four basic components - structure, systems, services and management - and the interrelationships between them." Source: Intelligent Buildings Institute (IBI)

  4. Commonalities Green Building Smart Building Integrated design Individual comfort control Indoor environmental quality Productive workplace Flexibility Energy efficiency Automatic climate response Advanced controls Eco-friendly materials Ecological site planning Advanced security and communications systems Water efficiency Advanced structural system Transportation efficiency

  5. 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 (>$5 possible)

  6. 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

  7. Task-Ambient Conditioning

  8. 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
