The Merced campus of the University of California was designed for high energy efficiency and minimum peak loads. An energy management and control system monitors energy use and building performance, providing the fundamental real-time data for continuously improving campus operations and energy efficiency. To minimize peak load, a traditional demand side management technology (a two million gallon chilled water thermal energy storage system) was adopted on campus to shift peak demand from afternoon to midnight permanently. In the summers of 2008 and 2009, UC Merced participated in two demand response (DR) events through PG&E’s aggregator-managed portfolio program. DR programs aim at changing customers normal consumption patterns by changing the price of electricity over time or offering customers incentives to reduce energy use during periods of either high electricity costs, grid constraints, or emergencies. This seminar presents energy performance and demand savings achieved during the two DR events both at the whole campus and individual building levels, followed by a detailed analysis of energy end use for both building systems and HVAC components. It also presents the effects of DR strategies on zone temperatures and CO2 levels as well as DR economics. For more information about this seminar, please contact: Sila Kiliccote (510) 495-2615
