Automation Goals and Definition
Research GoalsCost - Develop low-cost, automation infrastructure to improve DR capability in CaliforniaTechnology - Evaluate “readiness” of buildings to receive signalsCapability - Evaluate capability of control strategies for current and future buildings
AutoDR Definition - Fully automated signal for end-use controlSignaling – Continuous, secure, reliable, 2-way communication with listen and acknowledge signalsIndustry Standards - Open, interoperable standard control and communications to integrate with both common EMCS and other end-use devices that can receive a relay or similar signals (such XML)Timing of Notification - Day ahead and day of signals are provided to facilitate a diverse set of end-use strategies

DR Automation Server and Client
4 Energy Management Control System (EMCS) and other systems carry out shed based on pre-programmed strategies.
3 Polling clients request price level and event data every minute
2 Price-Level and DR event signals sent on DRAS
Utility sends DR notification to DRAS1

Next Steps – Auto-DR and Related Research Complete final draft of Open DR Automation Server and
client specification (May 2008) Facilitate implementation of open standards in state and
national DR efforts Explore links to Building Codes (Title 24) Ensure compliance of Global Temperature Adjustment
in 2008 Building Code (Title 24) Explore continuous energy minimization, energy
management systems, and building codes

Behavior Research
DR is a behaviorally driven systemBehavior research explores “why and
the how” not “who and the what”Current projects – residential and small
commercial DR rates and technologiesField tests in summer 2008
