Karl Johnson Achieving Energy-Effective Lighting With an Integrated System EPRI, 3412 Hillview Avenue, P.O. Box 10412, Palo Alto CA 94303, USA Abstract The search for more energy-efficient lighting has led to commercial lighting innovations, but some efficiency improvements have adversely impacted lighting quality. The Electric Power Research Institute (EPRI) teamed with a major luminaire manufacturer and a group team of utilities to develop, produce, and demonstrate an advanced lighting system. The resulting system integrates optically sophisticated, high-efficiency luminaires and electronic ballasts with occupancy and dimming controls - producing high-quality, efficient, energy-effective lighting that also addresses glare issues associated with the use of video display terminals (VDTs). The comprehensive set of luminaires are about 70% efficient and meet all criteria of IESNA RP-24 while using 10,8 W/m2 (1 W/ft2) or less. These lighting products are now being marketed as a package with the intent of promoting energy efficiency, the convenience of a sole-source warranty, and beneficial components such as electronic dimming ballasts. As a next step, EPRI is working with utilities, government, and other groups to develop this integrated approach into a nationally recognized criteria for customers, utilities, and manufacturers to expand this use of energy-effective lighting systems.
