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

9. Task-Ambient Conditioning

11. 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
