Poor School Ventilation May Lead to Illness, Study Says
A majority of California elementary classrooms fail to meet the state's minimum ventilation standards, according to a study by Lawrence Berkeley National Laboratory researchers published in the journal Indoor Air. Â The state's ventilation standard calls for seven liters of fresh air per person to replace indoor air every second, but the average ventilation rate of the classrooms studied was four liters per second. The researchers said that if classroom ventilation rates met state standards, students' illness-related absences would decline by 3.4%.Â
