Healthy Schools: Indoor Air Quality

Most people are aware that outdoor air pollution can damage their health, but many do not know that indoor air pollution can also cause harm. Environmental Protection Agency (EPA) studies indicate that indoor levels of pollutants may be 2-5 times, and occasionally more than 100 times, higher than outdoor levels. This is of particular concern because it is estimated that most people spend about 90% of their time indoors.
Failure to prevent indoor air problems, or failure to act promptly, can have consequences such as:

  • increasing the chances for long-term and short-term health problems for students and staff
  • impacting the student learning environment, comfort, and attendance
  • reducing productivity of teachers and staff due to discomfort, sickness, or absenteeism
  • faster deterioration and reduced efficiency of the school physical plant and equipment
  • increasing the chance that schools will have to be closed, or occupants temporarily moved
  • straining relationships among school administration and parents and staff
  • creating negative publicity that could damage a school’s or administration’s image and effectiveness
  • creating potential liability problems

Good indoor air quality contributes to a favorable learning environment for students, productivity for teachers and staff, and a sense of comfort, health, and well-being for school occupants. These combine to assist a school in its core mission — educating children.
