Energy Saving Benefit Analysis of Green Construction Using Energy-Efficient Lighting Equipment

Abstract:

It's an important topic that how to improve the illumination but decreasing or no increasing the electricity loads. The energy-efficient lighting equipment in the study was T5 lighting fixture combining with High-efficiency Reflector and Low-loss Diffuser Plate. The High-Efficiency Reflector could reflex the luminous energy above 97%. The illuminance could be improved largely through using the High-Efficiency Reflector without additional power. The High-Efficient Equipment illuminated the environment with low glare by the lights through the plate. Saving electricity was 47.5% and the measured illumination was increased more than 2 times in case one. The saving electricity was 30% and the measured illumination was increased about 1.5~2 times in case two. The specific benefits using energy-efficient lighting equipment were saving energy and enhance illumination. Cost of the investment achieved balance about 9.5~13.3 months. The additional value was a lighting environment with uniformity and low-glare. The energy-efficient lighting equipment could be an option of green construction.
