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...

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 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...

This project examines the site net energy consumption of a sample of units in the UC Davis West Village community. The primary goals were to (1) study energy consumption and production in order to determine if this West Village sample is achieving its zero net energy goals and (2) determine the...

The goal of these retrofit projects was to understand the costs and energy savings attributable to retrofit ground-source heat pumps for heating and cooling applications and to assess performance under different climate conditions typically found in...

The project’s objective is to identify scalable, deployment-ready technologies that can hasten the transition to zero net energy homes in PG&E territory. Four of a total of fourteen existing residential structures, the Domes, at UC Davis were retrofitted with energy efficiency improvements...

Scaled placement of Advanced Lighting Controls platform and 2x4 LED panels. PG&E had a unique opportunity to verify the energy efficiency potential for two similar floors of a large office building where one floor kept the T-8 3-lamp fluorescent fixtures and the second floor replaced them with 2x4...

This report is the second phase of a technical assessment evaluating retrofit technologies for existing SMB Packaged HVAC applications. Phase I of this project, completed in 2012, consisted of a market assessment and selection of technologies for field study. Phase II of this project consisted of...
