| Abstract | The comfort and health of students may be affected by contaminated interior environments. One of the key elements for improving academic performance is ensuring proper ventilation and indoor thermal comfort. This study aimed to assess the eff ectiveness of ventilation and measure temperature and humidity levels in several primary school classrooms in southern Iraq's Maisan Province. Utilizing a high-precision sensor, the study was conducted in 26 schools (22 public and 4 private) dispersed throughout the province, where thermal conditions and carbon dioxide (CO2) concentrations were tracked for seven months as an alternative to evaluate ventilation effi ciency by Smart air monitoring device. According to the results of CO2 concentration were around 516 - 3,477 ppm, most classrooms had high CO2 levels owing to poor ventilation, exceeding the ASHRAE standard of 62.1. During several monthly readings, the temperature was around 15 - 32.3 0C and relative humidity levels were 18.9 - 79.4%, exceeding the ASHRAE standard 55%. This can be ascribed to the considerable number of pupils occupying the space in the room and the eff ect of classroom and school building characteristics on indoor air quality. As a result, practical, straightforward steps are required to improve ventilation effi ciency. |
