Indoor Air Quality

Indoor Air Quality (IAQ) refers to air quality within and around buildings and its effects on the health and comfort of people inside those structures. Good IAQ enables healthy learning environments where students, teachers, and staff are more productive. Poor IAQ can increase the spread of illness, reduce participation in class and school functions, and negatively impact an institution’s reputation and the community’s trust. Indoor Air Quality’s already prominent place among educators has surged as school officials, parents, and communities seek better solutions to prevent airborne illnesses.

Indoor Air Quality Essentials

  • EPA studies show that human exposure to indoor air pollutants may be two-to five-times – and occasionally more than 100 times – higher than outdoor levels.
  • Reports indicate organizations are still spending millions of dollars on surface disinfection, despite evidence that COVID-19 is rarely transmitted via contaminated surfaces. Few countries, however, have invested in major efforts to improve IAQ.
  • IAQ can be affected by numerous contaminants found inside a building or drawn in from the outdoors; pollution includes particulates, fibers, mists, gases, mold, chemicals, carbon dioxide and other emissions, cleaning and maintenance materials, and more.3
Most people spend 90% of their time indoors
Indoor Air Quality also can be affected by school building and room occupancy rates, traffic flows, seasonality, location, as well as building age and design.
  • The rate at which outdoor air replaces indoor air is described as the air exchange rate. When there is little natural infiltration (fresh air through windows and doors) or mechanical ventilation to improve air quality, that rate is low and pollution levels can increase.
  • Good IAQ, through adequate ventilation in schools and classrooms, has been shown to reduce absences and
    transmission of infections diseases; improve teacher and staff health and productivity; and improve student test
    scores and attention rates.

HVAC air circulation installations should provide all rooms with both air exhaust and fresh air supply and should be run at maximum outside airflow settings for at least two hours before and two hours after school buildings are occupied to achieve adequate air quality.
