Project SummaryThis energy efficiency study determined the demand reduction and energy savings of 12 vertical sash, variable air volume fume hoods. The assessment compared the volumetric air flow rates of fume hoods with and without automated sash positioning control systems (ASPCS). Twelve hoods...

Project SummaryThe BreezeAir single-stage advanced evaporative cooler is an Australian product that has recently been introduced into the U.S. market. This product differs from U.S. advanced technology in that it uses 4-3.5 inch thick pads rather than 1-8 or 12 inch thick pad. The result is twice...

Project SummaryPumps and fans are responsible for about 40 percent of motor energy use and account for more than a quarter of industrial electricity consumption nationally. The potential savings are more significant in pump and fan systems than for motors alone because pump energy use varies as...

Project SummaryThis technology relies on plastic optical fibers to guide beams of light where the light source is located outside of the refrigerated display case. The fiber optic system is going to replace very high output fluorescent lamps that can be found in low-temperature reach-in...

Project SummaryAir conditioning (AC) is the primary cause of peak electrical demand during California’s hot summers. This project evaluates air conditioners that perform better in hot dry conditions, resulting in reduced peak loads at critical times. The field test compared the performance of...

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...
