Schools that provide optimal indoor environments see improved student performance and, if designed well, can also boost energy efficiency and reduce the carbon footprint.

According to a report by the World Green Building Council, providing ample daylighting and energy efficient LED lighting can reduce emissions while improving achievement. For example, the report found that students in the U.S. showed a 36% increase in oral reading fluency when exposed to high-intensity light, while those in standard lighting conditions increased by only 16%.
