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...

A field evaluation that collects energy savings, incremental costs, feasibility, conflict with other building practices for one of the measures under consideration for the 2016 T-24 standards: High Performance Attics.  Key problems solved: example moderate cost methods of achieving objectives,...

In support of California’s strategic plan to accelerate the penetration of energy efficiency technologies, this report presents the findings of a field evaluation of Tier 2 advanced power strips (APS) installed at residential audio/video (A/V) systems and commercial office and computer lab...
