Good writeup on the importance of air quality monitoring in schools:

"...good air quality improves students’ ability to learn. A study by the
Indoor Air Quality Scientific Findings Resources Bank reported that student
performance increased between five and ten percent when the room’s
ventilation rate was doubled. A separate report revealed that students in
classrooms with more fresh air scored 14 to 15 percent higher on
standardized test scores compared to students in classrooms with less
ventilation."

Now if the lights could sensor light levels, temperature, & air quality measures, that could make for quite a smart learning space....
