In 2012, the University of California, Davis (UC Davis), Energy Institute initiated a project funded by the Emerging Technologies Program at the Pacific Gas and Electric Company (PG&E) to retrofit existing residential structures through energy efficiency improvements and with ground source...

As part of our work toward Advanced Lighting Control Systems (ALCS) incentive programs, quantifying the savings from ALCS has emerged as one of the biggest hurdles in adoption. In particular, estimating and verifying savings from daylight harvesting is challenging because savings are highly...

Project Summary This report documents a field evaluation of the Munters EPX 5000 installed at a grocery store in San Ramon, CA. The technology studied is an indirect evaporative and vapor compression hybrid dedicated outside air supply (DOAS) system. This study was performed after a lab...

PG&E worked with a retail grocery store chain to study heat recovery in a new supermarket in Santa Clara County, California.  Energy analysis and field monitoring were conducted to better understand the natural gas savings and consequent electric energy penalty associated with a heat...

This evaluation project consisted of a commercially available outdoor lighting product market assessment, a comparison of manufacturer claims regarding these products, and a laboratory evaluation of representative xenon products marketed for use in the outdoor sector. Laboratory test results...

This effort identifies best practices for developing a cost-effective All High Efficacy (AHE) residential lighting measure through the evaluation of emerging residential lighting design practices, purchasing processes, installation practices and the end-user experience associated with AHE lighting....

This project evaluates the performance and savings potential of driver integrated linear LED tubes (~22W per lamp) at one demonstration site as a potential retrofit for existing linear fluorescent T8 fixtures (28-31W per lamp). The project also integrates the use of wireless lighting controls to...

This study evaluates the operation and capabilities of Demand Response (DR) controllers applied to single-speed residential pool pumps using ZigBee as the communication link between the SCE smart meter and the gateway. Communication to the DR controller is a component of the tested systems. Demand...

In an innovative attempt to address the growing issue of residential plug-load in the State of California, the Pacific Gas and Electric Company (PG&E) and the Sacramento Municipal Utility District (SMUD) launched the Retail Plug-Load Portfolio (RPP) Trial in 2013 and 2014. The RPP Program uses a...

Joint utility project that:  1)Estimates the number and types of labs in California; 2)Estimates the number and types of energy-consuming and water-consuming equipment used in California labs; 3)Assesses operational and behavioral opportunities for efficiencies in how laboratory equipment in...
