This review investigates the energy savings potential of an adaptive refrigeration controller for walk-in freezers and refrigerators. The technology continuously monitors conditions of a refrigeration unit and controls the system components in real time. Our study monitors the use of specific...

Wireless pneumatic thermostats (WPTs) present a retrofit opportunity that can enable energy-saving control strategies to be implemented in commercial buildings with older pneumatic HVAC controls. The goals of the scaled field placement were to evaluate the implementation of WPT systems at four...

The project assessed the energy savings potential of LED lighting with an advanced lighting control system (ALCS) in a commercial office building. The control strategies were implemented and monitored in the following phases: 1. Existing fluorescent lighting 2. New LED luminaires at full...

Pacific Gas and Electric Company (PG&E) partnered with the California Lighting Technology Center (CLTC) at the University of California, Davis, to assess how education or incentive programs for lighting that uses light-emitting diode (LED) technology might best serve retail business owners...

The growing availability of detailed energy information for California’s utility customers makes possible new programmatic approaches for delivering energy efficiency and demand management services. A 2011 technology assessment that provided a grocery customer with an Energy Information...

Quality Maintenance (QM) of residential heating ventilation and air-conditioning (HVAC) systems is defined by ANSI/ACCA Standard 4 (ACCA4) . To implement the standard, a technician needs to take measurements and do the analysis necessary to perform fault detection and diagnostics (FDD). In support...

The goal of the project was to determine the energy savings potential provided by LED lighting as compared to the designed metal halide (MH) high intensity discharge (HID) base case for outdoor area lighting applications, especially underground parking structures. This demonstration project...

The goals of the project were to demonstrate the potential of LED as a viable replacement lighting technology and determine the energy savings potential provided by LED general illumination as compared to incandescent, fluorescent, and CFL base cases. This demonstration project validated that...

The objectives of this project were to upgrade the theater lighting to state of the art, energy efficient theater lighting, compare the quality of LED lighting with the base case halogen, determine the energy savings potential provided by the LED solution and ensure that the selected LED solution...

The goals of the project were to determine the acceptance and energy savings potential of eHID ballast lighting system as compared to traditional HID magnetic ballast lighting system. This project validated that properly designed eHID lighting systems, meaning proper lamp and reflector, can...
