3. California Energy Commission - Public Interest Energy Research Program Automation Goals and Definition Research Goals Cost - Develop low-cost, automation infrastructure to improve DR capability in California Technology - Evaluate “readiness” of buildings to receive signals Capability - Evaluate capability of control strategies for current and future buildings AutoDR Definition - Fully automated signal for end-use control Signaling – Continuous, secure, reliable, 2-way communication with listen and acknowledge signals Industry 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
