LEED IEQ 8.1

LEED credit Indoor Environmental Quality 8.1 uses two specific times—9 am and 3pm on September 21st—to determine if the light levels in occupied areas reaches a threshold of 75% in the range of 10 to 500 footcandles. Achieving this threshold qualifies the project for this LEED point, and schools can earn an extra point if they exceed 90%.
