Indoor Air Quality

Indoor air quality, or IAQ, refers to the indoor working environment on campus. Where building ventilation systems are unable to keep indoor working areas within certain measurements these areas are sometimes referred to as having “poor indoor air quality."

In general, an area with “good” indoor air quality will have air temperatures between 73°F and 79°F in the summer or between 68°F and 75°F in the winter, relative humidity levels between 30% and 60%, carbon dioxide levels below 1075 ppm, carbon monoxide levels lower than 9 ppm, and no obvious drafts or offensive odors.

IAQ concerns frequently peak on campus in late spring and early autumn, as the heating and cooling systems are changing over for the new season. Air temperatures during these change‐over periods are frequently uncomfortable and poorly regulated, especially in older facilities. Relative humidity levels can get very low in some buildings on campus during the heating season, leading to eye and throat irritation due to the dryness of the air. Fortunately, our facilities maintenance staff are very aware of what makes good IAQ and they work hard to keep things in good shape for building occupants.

Please report any perceived indoor air quality issues to your risk and safety manager or your supervisor as soon as you notice them.
