Project SummaryThe introduction of the low wattage ceramic metal halide (CMH) lamp and associated luminaires has created a new, efficacious lighting alternative to incandescent. This report evaluates the practical application of the CMH lamp in the retail environment. The objective of this report...

Project SummaryThe development of reduced wattage 4-foot linear fluorescent T8 lamps and research into spectrally enhanced lighting have both provided new avenues for potential energy savings. This project takes a look at the two new areas to see if spectrally enhanced lighting can expand the...

This project implemented demand response strategies for interruption of pumping of well water during periods of high electric demand. The goal was to determine if water agencies can maintain their water supply and pressure to their customers during an extended shutdown of all their supply well...

This report compiles and summarizes current information on market-ready evaporative cooling technologies based on reviews of published literature, public agency studies and manufacturers’...

Project SummaryThis project evaluates the demand response effectiveness of a demand control lighting (DCL) system during peak use periods. The DCL system was installed at a retail hardware store to verify the technology capabilities and to test it in real world conditions. This demand response...

Project SummaryManufacturers of energy storage modules (ESMs) claim that their systems, in addition to providing load shifting capabilities, can also deliver energy savings to end-users. While previous studies have shown that, given the right set of circumstances, an ESM system can be used for...

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...
