IES LD+A Research Matters: Smart Corridors Light the Way to Energy Efficiency

Publication Date: 

If a light dims down to the minimum recommended illumination level in a secondary space and no one is around to see it, does it really make a difference? Research shows yes—it makes a big difference in reducing lighting energy use.

Laboratory and field testing of prototype systems that dim corridor lights down to 50% or less of full output during vacancy periods and increase to full output during occupancy show significant reduction in lighting energy use and great potential for effective electricity demand response.
