Whats Really Happening Building Smart Building Green Smart

What’s Really Happening?

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

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)

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

Wireless Measurement & Control Objective: w. Study how small multi-modal sensing technology could affect the operation of buildings Motivation w Wireless (50 -90% of sensor cost due to wiring) w Small, could be embedded or attached to furniture, ceiling tiles, walls (“smart dust”) w Self locating, could also be used to keep track of furniture and equipment w Low cost (>$5 possible)

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

Task-Ambient Conditioning

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