A Study on the Energy Conservation Efficacy of Secondary-Reflection Lighting Design Adopted in a Conference Hall

Abstract:

A conference hall is a large meeting space that requires high-wattage lighting equipment to provide sufficient illumination. Ceiling lights are not easy to maintain and cause glare in the seating area. This study simulates the interior lighting of the International Conference Hall in the Magic School of Green Technology (MSGT) using high efficiency ceramic metal halide lamps that replace the general design luminaires, and PL and fluorescent lamps. We use the secondary reflection of light to reduce glare and improve lighting uniformity. The results show that high efficiency lighting can reduce by 25% the standard lighting equipment and still provide the same illumination levels. Furthermore, the overall conference hall lighting uniformity increases from 0.59 to 0.78.
