Building Energy Information Architecture
Create the information infrastructure for deep energy reductionExisting systems sized for peak and designed for continuous activity
Reclaim the idle wasteExploit huge gap in peak-to-average power consumption
Continuous demand responseChallenge “always on” assumptionRealize potential of energy-proportionality
From IT Equipment …Better fine-grained idling, faster power shutdown/restorationPervasive support in operating systems and applications
… to the OS for the Building… to the Grid

Project Overview 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 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
Full TCP/IPv6 in 32k ROM, 5k RAM Allows efficient embedded implementations of sMAP New open-source project started at Berkeley; worldwide user base Platform for experimentation with MACs and Routing Protocols; provide
feedback to standards bodies (IETF) Enable prototype of next-generation smart grid technology
