Project SummaryThis project evaluates the potential demand response of small commercial HVAC systems and residential central air-conditioners using programmable communicating thermostats (PCTs) assuming PCTs were incorporated into the 2008 California Building Energy Efficiency Standards (Title...

Project SummaryThe objective of this project is to develop, implement, and field test demand response (DR) strategies for fresh water (well water) supply and irrigation system customers while leveraging the customer’s existing control infrastructure. The Rancho California Water District (RCWD) in...

Project Summary: Storage gas water heaters are the predominant residential water heating appliance used in Pacific Gas and Electric Company (PG&E) service territory and throughout California. Gas storage water heaters are characterized by low first cost, hot water delivery characteristics...

Project SummaryCalifornia and other states with hot dry climates need air conditioners that maximize indoor temperature reductions for the expended energy. This is particularly true at high outdoor temperatures. This study found that existing single speed air conditioners utilizing outdoor units,...

Project SummaryResidential evaporative condensers offer effiency advantages over conventional air-cooled conditioners by utilizing evaporative cooling to improve condensing unit performance. The evaporative cooling process results in a 30-40F reduction in peak refrigerant condensing temperatures...

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 SummaryImplementing electrodialysis wine stabilization instead of traditional cold stabilization has been demonstrated to show electrical energy and demand savings. This Project utilizes the quantitative analysis models (thermodynamic and glycol cooling model) developed in a previous study...

Project SummaryLight-emitting diode (LED) lights are emerging as a viable alternative for outdoor locations such as parking lots, parking garages, and streets, which typically use wallpaks and bollards lit with high wattage, high intensity discharge (HID) or fluorescent lights. In addition to...

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...
