The high concentration of lights in Hospital ORs leads to a significant amount of heat generated in a small space.  The cooling load of the OR can often drive the cooling provided to the entire hospital, with a significant amount of reheat needed in other areas of the hospital.  Removing...

Project SummaryA limited evaluation of two new heat pump water heaters (HPWHs) was conducted in the water heater laboratory at the PG&E San Ramon Technology Center. The objective of the testing was to investigate the operating characteristics of HPWHs in comparison with other types, and their...

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...
