High Efficiency Lighting

Back to Buildings

Lighting is one of the top three sources of energy use in buildings, which makes it a significant contributor to greenhouse gas emissions. Developments in high-efficiency white-light LED technology over the past decade have significantly reduced the energy we need to light our buildings. Continued incremental technology improvements and increasing manufacturing scale will result in continued cost reductions and efficiency improvements in LEDs in the years ahead. Nevertheless, there may be an opportunity to reduce lighting energy in buildings even further by going “beyond LEDs,” through the development of advanced new concepts in high efficiency lighting.
