Project SummaryData centers require continuous air conditioning to address high internal heat loads (heat release from equipment) and maintain indoor temperatures within recommended operating levels for computers. Air economizer cycles, which bring in large amounts of outside air to cool internal...

Project SummaryFume hoods keep laboratories safe and clean by removing unwanted gasses through filters and exhaust fans. But in the process, they consume considerable electricity. One laboratory fume hood uses as much electricity as three homes and produces the greenhouse gas emission equivalent of...

Project SummaryIntroduction During 2006 Lawrence Berkeley National Laboratory (LBNL) and the Demand Response Research Center (DRRC) performed a technology evaluation for the Pacific Gas and Electric Company (PG&E) Emerging Technologies Programs. This report summarizes the design, deployment,...

Project SummaryThis project demonstrated the functionality of a refrigerant based energy storage (RBES) for air conditioning (A/C) system under different cooling load conditions. The RBES A/C system is designed to shift on-peak A/C demand to non-peak periods. It applies to buildings with a cooling...

Project SummaryIn this project, a demand control lighting (DCL) system was installed in a portion of a retail hardware store to evaluate the demand response effectiveness of this technology. Most lighting control systems turn lighting circuits on or off and are hardwired to an energy management...

Project SummaryProgrammable communicating thermostats let home owners adjust their thermostat to reduce cooling/heating loads and save money. The technology also gives Southern California Edison (SCE) the opportunity to better understand usage patterns and reduce demand during peak periods. But...

Project SummaryThis report describes data sources, results, and provides links to spreadsheets containing the input data and calculations used in the 2008 Time Dependent Valuation (TDV) update to include demand response. There is an accompanying report that describes the methodology used to develop...

Project SummaryThe Building Energy Efficiency Standards (Title 24) are based upon the cost-effectiveness of efficiency measures that can be incorporated into new buildings in California. Historically, the method to assign value to energy efficiency measure savings has been calculated on the basis...

Project SummaryOccasionally, the utility electric grid systems undergo voltage fluctuations caused by faults. These faults are caused by storms, accidents, debris on lines, and equipment failures. Normally, protective relaying is used to disconnect the problem lines and then voltage automatically...

Project SummaryThis project explored the communications technologies and products needed for a Southern California Edison summer load control program for swimming pool pumps. The program work consisted of: ~ Identification and analysis of communications technologies for use with pool pump load...
