Emergency and standby generators are common place for industries, institutions, hospitals, government agencies, schools and most commercial facilities that need emergency power. Most generators required block heaters to keep the engine block warm and ready to run within 15 - 30 seconds. Air Source...

This project assesses the energy and demand savings potential of LED technology in residential downlighting applications through lab evaluations and field monitoring of actual kitchen usage...

The objective of this study was to assess the status of the light-emitting diode (LED) under-cabinet lighting and measure incremental energy and demand savings over their T8 linear fluorescent and incandescent counterparts. Photometric and power tests will be conducted in the Southern California...

This lab evaluation project evaluates the energy and demand savings of light-emitting diode (LED) lighting systems and traffic-sensitive lighting controllers in low-temperature reach-in refrigerated display cases. Additionally, LEDs may have longer life and lower maintenance costs. The LED systems...

Water cooled air conditioners have been around for several years and have an excellent performance rating out of the box, an EER of about 17. However, the experience has been that water-cooled condensers can become fouled in a very short time, circumventing their performance and become a...

Recognizing the benefits of benchmarking, the Executive Order (EO) S-20-04 requires all state-owned buildings to be benchmarked with support of the utilities. Because of the requirements of the EO S-20-04, this project was initiated. The main goals for this project are to:Develop software that...

This project verified the performance of several manufacturers’ products through laboratory tests and compared the resulting data to the manufacturers’ product specifications. The main areas of interest were color temperature, color rendering index lumen output, power consumption, power factor, and...

This project assesses the status of the technology and measure the potential incremental energy savings and demand reductions over halogen MR16 lighting systems. Photometric tests conducted at the Southern California Lighting Technology Center (SCLTC) demonstrate the differences and similarities of...

A new generation of high efficiency display cases has recently been marketed by three of the leading U.S. case manufacturers. This new high efficiency display case requires roughly 40% less cooling load compared to a standard medium-temperature open vertical display case (900 Btu/hr/ft vs. 1,448...

In response to an overwhelming interest in innovations in LED lighting technology for the outdoor area lighting applications, San Diego Gas & Electric’s Emerging Technologies Program (ETP) objectives with this assessment were: • identify potential LED solution for outdoor area lighting,...
