Automated Demand Response Strategies and Commissioning Commercial Building Controls

National Conference on Building Commissioning: April 19-21, 2006 Automated Demand Response Strategies and Commissioning Commercial Building Controls Mary Ann Piette, David Watson, Naoya Motegi, Sila Kiliccote Lawrence Berkeley National Laboratory PIER Demand Response Research Center Eric Linkugel Pacific Gas and Electric Company Synopsis California electric utilities have been exploring the use of dynamic critical peak pricing (CPP) and other demand response programs to help reduce peaks in customer electric loads. C P P is a new electricity tariff design to promote demand response. This paper begins with a brief review of terminology regarding energy management and demand response, followed by a discussion of D R control strategies and a preliminary overview of a forthcoming guide on D R strategies. The final section discusses experience to date with these strategies, followed by a discussion of the peak electric demand savings from the 2005 Automated CPP program. A n important concept identified in the automated D R field tests is that automated D R will be most successful i f the building commissioning industry improves the operational effectiveness of building controls. Critical peak pricing and even real time pricing are important trends in electricity pricing that w i l l require new functional tests for building commissioning.
