Lighting Systems

Lighting Profile.jpg

Commercial lighting uses about 4.0 quads of primary energy annually – more than 20% of total commercial building energy use in the United States. Lighting represents a large end-use of electricity and is often targeted for energy savings through energy-efficient lighting and control systems. Through the Lighting Systems Technology Research Team, partners work together to reduce lighting energy use by sharing insights and experiences related to emerging lighting and control systems and documenting the application of solutions. By developing resources like lighting specifications and application guidance, the Team helps build confidence and demand for higher efficiency technology.
