Indoor Air Quality (IAQ)

  • Providing a healthy and comfortable learning environment for students and staff is important to Saint Paul Public Schools.  As a result, maintaining good Indoor Air Quality across the district is a high priority.


    Working with EPA and their IAQ Tools for Schools Program, the District developed an IAQ Management Plan that will help monitor and improve the quality of air in all SPPS buildings.

    The objectives of this IAQ Management Plan are:

    • Reduce the levels of indoor air pollutants through preventive measures such as routine maintenance activities, periodic building evaluations and inspections, and IAQ-specific policies.
    • Provide and maintain adequate air exchanges by maintaining ventilation equipment.
    • Respond to IAQ-related concerns and problems in a thorough and prompt manner, through investigation, documentation, and effective communication.

    During February and March of 2016, all schools and administration buildings within the district were surveyed  to identify IAQ-related issues. SPPS worked with the Institute for Environmental Assessment (IEA) to conduct the surveys, which looked at all occupied spaces including classrooms, offices, gymnasiums, pools, cafeterias, libraries, and auditoriums. The surveys are based on the guidance of EPA's Tools for Schools, and were modified to include additional information pertinent to SPPS.

    The district-wide survey collected information regarding physical space characteristics, user-controlled elements like presence of space heaters, animals, and food, as well as information about water damage, mold, mildew, paint, pests ,orders, chemicals, exhaust/HVAC equipment, carbon dioxide, carbon monoxide, temperature, and relative humidity. Sampling was conducted while spaces were occupied to ensure accurate measurements.

    Issues that have been identified through the IAQ survey process and need to be addressed were prioritized based on the following criteria:

    • Impact on IAQ
    • Impact on comfort
    • Health and safety risk
    • Severity
    • Floor area impacted
    • Reports or concerns of health complaints
    • History of the issue
