Classroom conditions and CO2 concentrations and teacher health symptom reporting in 10 New York State Schools Abstract This study assessed the relationship between teacher-reported symptoms and classroom carbon dioxide (CO2) concentrations. Previous studies have suggested that poor indoor ventilation can result in higher levels of indoor pollutants, which may affect student and teacher health ...
CO2 Sensors will automatically regulate fresh air delivery so that over-ventilation does not occur. In fact if fresh air is being delivered from another location such as an open window, hallway or another unoccupied classroom, the sensors will react to this source of fresh air and adjust the ventilation rate accordingly. CO 2 control is also an ideal way to control ventilation based on ...
