Acceptable Co2 Levels In Classrooms. That level is easy to maintain when a classroom is empty. The researchers noted that typical carbon dioxide concentrations outside are approximately 380 parts per million while inside office buildings the concentrations usually arent any higher than 1000 parts per million. Classrooms that are not properly ventilated could have CO2 levels reaching beyond 3000 ppm compared to the healthy level of 1000 ppm. Carbon dioxide gas detectors can provide detection and automatic ventilation control for conference rooms classrooms meeting halls or similar applications.
CO2 in School ClassroomsAs reported in a Berkeley Labs study high classroom CO2 levels in can significantly impair decision-making performance. Complaints of drowsiness and poor air. Laboratory and field studies have shown that this rate of ventilation will dilute odors from human bioeffluents to levels. At the activity levels found in typical office buildings steady-state CO 2 concentrations of about 700 ppm above outdoor air levels indicate an outdoor air ventilation rate of about 75 Lsperson 15 cfmperson. Normal background concentration in outdoor ambient air. Recommends a minimum of 8Lsec per person for classrooms.
