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."

Wireless Measurement & Control
Objective:Study how small multi-modal sensing technology could affect the operation of buildings
MotivationWireless (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)
Wireless Measurement & Control
IssuesPower sourcesWhat to do with additional
data points?
MethodCollaboration with other UCB
research groupsSensor developmentComputer simulations of
sensor networksDemonstration projects on
UCB campus
Task-Ambient Conditioning
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
