Lighting in parking lots and garages increases the visibility and sense of security for its users. The recommended light levels in parking lots and garages are included in the Illuminating Engineering Society’s Recommended Practice (RP) – 20 document. In the latest version of this document...

DX HVAC units are very often used in standalone retail, education, restaurant, and small to medium size office buildings. Among other reasons, small DX HVAC units have this market dominance in small and medium commercial buildings because they require little site-specific design, can be dropped...

Air conditioning loads drive peak demand and contribute to overall electric power consumption in California. In the summer, cooling loads are highest in the middle of the day when air conditioners are the least efficient. Rejecting waste heat from an air conditioner to a swimming pool rather than...

According to a study by the California Energy Commission (CEC), the agricultural sector accounts for 79 percent of California’s water use, which corresponds to 4 percent (over 10 GWh annually) of the state’s electricity use (CEC, 2005). One potential strategy for reducing agricultural...

This project will evaluate dedicated LED track lighting systems, which do not allow for conversion to other source types. Additionally, the use of LED screw-base lamps for use with traditional track lighting, current limiting devices and phase-cut dimming controls will be evaluated at both line and...

This report summarizes EM&T efforts at Southern California Edison from July 2018 through December 2018. It lists reports that were:- Completed- Initiated- Works still in progressAnd includes a detailed status for each DR...

SoCalGas is exploring the potential of including Warm Mix Asphalt (WMA) within their energy efficiency incentive portfolio offerings. A literature review of the technology is the first step in a larger market characterization study and technology assessment to determine incentive program viability....

Dispatchable pre-coolers have the potential to be used for utility load management if pre-coolers can be demonstrated to be a guaranteed demand reduction resource. Building on prior work testing evaporative pre-coolers, complete a laboratory study to determine the transient response and load...

This study was a continuation of the Central Valley Research Homes (CVRH) project which began in 2012. The CVRH project converted four existing single family buildings in Stockton, California into unoccupied laboratory houses for the purpose of evaluating energy savings associated with improvements...

San Diego Gas & Electric's Emerging Technologies (ET) program performed a measurement & verification (M&V) study of Phase Change Material (PCM) for commercial customers. PCM was studied in a high school classroom setting. This high school is located in climate zone 10 with the...
