Lighting & Electrical

Commercial lighting uses about 4.0 quads of primary energy annually - more than 20% of total commercial building energy use in the United States. Through the Lighting and Electrical Technology ResearchTeam, partners work together to reduce lighting energy use by sharing cost-effective solutions to interior and exterior lighting challenges and developing lighting specifications to build confidence and demand for higher efficiency technology.
