Indoor air quality (IAQ) is a critical component of occupant comfort, cognitive performance, and overall environmental health in educational settings. This field-based evaluation examines changes in key IAQ parameters—carbon dioxide (CO₂), oxygen, temperature, and relative humidity—at the beginning and end of regularly scheduled class sessions using a GrayWolf Indoor Air Quality Monitor. CO₂ concentrations are assessed as a surrogate indicator of ventilation effectiveness under normal occupancy conditions. The objective of this project is to evaluate whether classroom environmental conditions remain within commonly accepted comfort and ventilation benchmarks over the duration of instruction. Observed trends will be interpreted in relation to general dilution ventilation performance and building air exchange adequacy. Findings will contribute to a better understanding of how occupancy dynamics influence indoor environmental quality in academic spaces.
