This project will evaluate the energy savings, economic benefits, and market potential for recessed LED lighting equipped with multiple types of lighting control systems for food service sector. Lighting systems will include various types of recessed LED troffers installed in combination with...

The purpose of the project to demonstrate capabilities of AutoDR enabled OCSTs in light commercial settings. This phase will field test a different vendor than phase 1, at a different fast food...

Project Summary Replacing existing and vintage gravity wall furnaces with high-efficiency models can save gas in apartments, average 35.5...

Project Summary Field tests confirmed 1.07 gpm appeared to be the low limit for pre-rinse spray valves used in 6 restaurants in the LA area. The low-flow retrofit achieved an average of 24.9% energy savings, despite an observed increase in average daily use time. The energy and water savings...

Project Summary Retrofit by adding VFD controller to fractional horsepower Hot Water Recirculator in single loop domestic use for apartments and hotels, etc. can save gas 15.6% with a compensating but modest increase in hot water usage of 13.4%; or an average gas savings of about 27 therms per...

The project was initiated to test emerging evaluation approaches to identify operational and technical opportunities to optimize energy and water usage of pressurized irrigation systems. The combined evaluation incorporates information derived from a "standard" pump efficiency test and a "standard"...

This project tested performance characteristics of pressure regulating valves and pressure compensating emitters from a variety of manufacturers. In addition to the research, the Consultant coordinated the implementation of these low-pressure components on a commercial agriculture operation and...

This study investigates the energy savings capability and potential of ultra-low temperature freezer monitoring systems when used as an energy consumption diagnostic tool. Ultra-low temperature (ULT) freezers are common in university labs and facilities involved in research and development...

Four different retrofit RTU controllers were tested on four 7.5 ton heat pumps serving office space at one building in San Diego. The operation of those units was alternated on a weekly basis from baseline to retrofit mode. Proper operation of the each controller was verified and the features of...

In many cases, buildings lack automatic ventilation feedback and are consequently over-ventilated. This report investigates the potential energy savings for a demand control ventilation (DCV) system with centralized air quality sensors. This technology aims to maintain or improve building comfort,...
