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 SummaryThis report provides methodology for calculating energy savings achieved by four major energy-saving measures for activated sludge processes. The report also lists software and hardware necessary for the implementations of the above-mentioned optimizations and control...

Project Summary This project develops and implements variable refrigerant flow (VRF) algorithms into the eQUEST building energy simulation program. While VRF systems are applicable to both residential and small-to-medium-sized commercial facilities, this project is limited to residential heat...

Project SummaryThis report summarizes the installation and assessment of light emitting diode (LED) luminaires at a department store in Northern California. Relying primarily on field testing, the project team conducted photometric and power measurements, as well as retailer satisfaction surveys...

Project SummaryThis research project studied the energy efficiency and power quality characteristics of power supplies used in servers. The findings revealed ways in which power consumption could be reduced, and the load capability of the servers increased. Banks of servers (also known as “data...

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 SummaryImplementing electrodialysis wine stabilization instead of traditional cold stabilization is demonstrated to show electrical energy and demand savings. This Project was done on 18,500 gallon of Pinot Grigio in two uninsulated tanks. Results indicated 99% (26,700 kWh) electrcity...

Project Summary:There are a variety of emerging technologies that have potential to save substantial energy and demand in the lodging industry. Some of these are targeted specifically to the hotel and motel markets, while others may have applications in multiple market segments. The nearest term...

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,...
