High-efficiency lighting systems and lighting controls can offer significant cost benefits and energy savings in commercial and industrial applications. However, implementation has been hampered by technological and market limitations, resulting in a lack of customer demand.
The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, with funding from the U.S. Department of Energy (U.S. DOE), conducted extensive research to identify and to seek ways of reducing the barriers limiting the wide acceptance and use of energy-efficient lighting systems. This research focused on dimming controls, including load-shed dimming and photosensor-activated daylight dimming, and automatic shut-off controls, including occupancy sensors and time clocks. (Architectural dimming in conference rooms and multi-function rooms was not included in this study.) Barriers to widespread use of whole building lighting control systems also were investigated and the progress in this area was reviewed. Finally, as part of this project, the LRC developed solutions to some of the identified barriers.
The LRC/U.S. DOE project, Reducing Barriers to the Use of High-Efficiency Lighting Systems, focused specifically on the barriers found in commercial and industrial applications that employ fluorescent lamp technologies. This focus was chosen because of major energy-savings opportunities that can be found in commercial and industrial sectors and with fluorescent lamp technology.
