Project SummaryIn this project, a wireless energy management system was installed in a government office building to evaluate the demand response effectiveness of this technology. The wireless system investigated in this project used modular components which could be activated by either the...

Project SummaryDaylit buildings, combined with automatic photocontrols, have enormous potential to deliver substantial energy and peak demand savings. As a result, utility-run efficiency programs such as Savings by Design, and the Title 24 Energy Efficiency Standards now promote the greater use of...

Project SummarySouthern California Edison’s (SCE) Emerging Technology Program assesses products that have the potential to reduce electric energy use. Area lights that use light emitting diodes (LEDs) are a new application of evolving LED technology where potential energy savings has not been...

Project SummaryThis project is a demonstration of the energy-efficient CFL downlight fixture developed by the California Energy Commission’s Public Interest Energy Research (PIER) program (PIER 500-04-005, December 2003). The project is being conducted in partnership with homebuilders, to...

Project SummaryThe Green Buildings Studio is a web service application designed to support designers who wish to model the energy implications of building and systems designs. It is designed to accept files from 3D CAD software or manual inputs of building designs and produce files compatible with...

Project SummaryThe development of reduced wattage 4-foot linear fluorescent T8 lamps and research into spectrally enhanced lighting have both provided new avenues for potential energy savings. This project takes a look at the two new areas to see if spectrally enhanced lighting can expand the...

Some recent studies have performed preliminary investigations into the differences in efficiency and operation of furnaces, including the evaluation of high efficiency prototype blowers. Unfortunately there is no uniform, single method of testing and comparing airflow and efficiency of competing...

Project SummaryModern K-12 classrooms host a variety of activities and need lighting systems that can accommodate them. An assessment of the Integrated Classroom Lighting System (ICLS) from Finelite, Inc., conducted for Pacific Gas and Electric...

Project SummaryThis assessment project will determine the potential demand and energy savings, as a function of hotel room occupancy rates, for replacing existing guest room bathroom wall switches with wall switches with a built-in occupancy sensor and LED nightlight. This new energy efficiency...

Project Summary:The Dimmable Stairwell Lighting Case Study will determine the energy usage and cost impacts of a retrofit stairwell lighting project at the Fillmore Center in San Francisco. This project will 1) calculate the pre-install energy usage, 2) calculate post-install energy usage, 3)...
