Project Summary The hypothesis guiding this project was that a deemed savings model can be created based on the analysis and simplification of variables involving the operation of a small energy management system (EMS)—including market segment, load type, climate zone, building schedule, and...

Project SummaryThis project evaluates the benefits and customer acceptance of electronic high intensity discharge (HID) ballasts in medium- and high-wattage applications, such as warehouses, gymnasiums, and big box retail stores. Benefits of electronic ballasts include increased energy efficiency,...

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 SummaryIn most plastic fabrication processes, plastic resin has to be dried to a specific humidity level before using it for fabrication. The technology under consideration, a new type of dryer for plastic resins, uses a revolving circular bed of desiccant material in a honeycomb structure....

Project SummaryA “control interlock” to stop air entering a dairy milking vacuum system. When milking cows, a pulsation unit lets atmospheric air into chambers at the milking claw which makes a gripping motion and then milk flows from the cow. When milk stops flowing, existing controls detach the...

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...

Project SummaryThis project will demonstrate technologies in the area of air management, operation strategy, and/or heating, ventilation and air conditioning (HVAC) air-side economization. For more information, please contact the sponsoring organization.Related Reports Data Center Energy Efficiency...

Project SummaryThe first phase of an evaporative cooler technology evaluation project conducted 2003 tested the performance of advanced evaporative coolers (AECs) that used 8 inch thick rigid media. The results showed that advanced coolers are 68-70% more efficient than conventional coolers....

Project SummaryThis project is a demonstration of the energy-efficient CFL downlight fixture developed by the California Energy Commission’s Public Interest Energy Research (PIER) program (PIER 500-04-005, December 2003). The project is being conducted in partnership with homebuilders, to...

Project SummaryThe Green Buildings Studio is a web service application designed to support designers who wish to model the energy implications of building and systems designs. It is designed to accept files from 3D CAD software or manual inputs of building designs and produce files compatible with...
