Project Overview
Building Applications
 Create the information infrastructure for deep energy reduction
 Existing
systems sized for peak and designed for continuous activity
 Reclaim the idle waste
 Exploit
huge gap in peak-to-average power consumption
 Continuous
demand response
 Challenge “always
on” assumption
 Realize potential of energy-proportionality
 From
IT Equipment …
 Better fine-grained idling, faster
power shutdown/restoration
 Pervasive support in operating systems and applications
…
to the OS for the Building
 … to the Grid
Grid-Building Interface
Applications
 Applications
are multiplexed on top of sMAP
 Google PowerMeter bridge sends live data to
the Google archive
 MySQL adaptor stores readings in a relational
database
 SmapQuery archives data in the
Amazon cloud and provides a
Internet
NoSQL–inspired query interface
 EveryBuilding places sensor streams
in a context with their physical location
 Android interface allows personalized feedback
 Future integration with existing Building
Management Systems

Universal RESTful Sensor Access: sMAP
Transmission
Distribution
 Simple, efficient,
Load
implementable anywhere
 Sharing of diverse physical
information
Conventional Electric Grid
Conventional Internet
 Respond to demand variability
 Expose “slack” in loads
 Overlain on existing internet,
