With the school season in full swing at colleges and universities, the last thing on their minds is that the indoor air could be impacting their students' health and performance. Yet, studies show that most schools have inadequate indoor air quality (IAQ) and that this results in increased health issues and lower student performance. Symptoms like headache, dizziness, and tiredness were found to be higher in classrooms with higher concentrations of carbon dioxide, as well as increased difficulty concentrating. Other studies found students had less attention and vigilance in classrooms with low IAQ, and even more negative impact on higher-order complex tasks. The U.S. Environmental Protection Agency (EPA) specifically recommends that schools have a comprehensive IAQ management plan. So, how can schools ensure a healthy learning and working environment for their students, faculty and staff, without accruing incremental costs to do so?
