Assessment Protocol
Each quarter, the facilities team evaluates IAQ in five designated locations per school:
- Cafeteria
- Gymnasium
- Library
- Classrooms (2)
When a school lacks one or more specified areas, an equivalent space or an additional classroom is selected for evaluation to ensure consistency in the assessment process.
Measured Parameters
The following IAQ parameters are meticulously evaluated during each assessment:
- Temperature: The measurement of ambient indoor air temperature.
- Relative Humidity (RH): The ratio of the current amount of moisture in the air to the maximum amount it can hold at that temperature, expressed as a percentage.
- Carbon Dioxide (CO₂): A colorless, odorless gas that indicates indoor ventilation effectiveness.
- Fine Particulate Matter (PM2.5): Airborne particles with a diameter of 2.5 micrometers or less, originating from sources such as combustion and dust.
- Coarse Particulate Matter (PM10): Airborne particles with a diameter of 10 micrometers or less, including dust, pollen, and mold spores.
- Formaldehyde (HCHO): A volatile organic compound commonly emitted from building materials and furnishings, known for its potential health effects.
- Mold and Mildew: A visual inspection is conducted to identify any signs of mold or mildew growth.
Response to Elevated Readings or Visual Indicators
Should any assessment reveal elevated readings or visual indicators of mold or mildew, the established IAQ Quality Assurance (QA) Plan is promptly initiated to address the issue. Spaces are subsequently retested until all readings pass (noted where Testing Type is Retest). In addition, the building engineer thoroughly reviews the ventilation systems in the assessed areas to verify proper operation. Any deficiencies identified during this review are meticulously documented and rectified promptly to ensure the ongoing integrity of the indoor environment.
