Project SummaryThis report assesses the energy savings potential and attendant visual impacts of four advanced lighting sources and systems used to externally light billboards. Assessment objectives include: determining lighting energy savings, light levels and uniformity, visual impacts, and...

This report provides a technology and market assessment of emerging network control and monitoring systems in street lighting applications.  Using network control and monitoring systems with streetlights has the potential to save a significant amount of energy.  These systems offer the...

Project Summary: In the hospitality industry in the United States, card keys are used almost universally to gain entry to guestrooms and other areas of hotels.such as swimming pools, exercise rooms, and laundry areas but not as part of energy management systems. The...

This report summarizes an assessment project conducted to study the performance of light emitting diode (LED) luminaires with network controls in a street lighting application. The project included installation of LED street lights with network controls on public roadways in San Francisco Public...

Project Summary The hypothesis guiding this project was that a deemed savings model can be created based on the analysis and simplification of variables involving the operation of a small energy management system (EMS)—including market segment, load type, climate zone, building schedule, and...

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...
