Sick Classrooms Caused by Rising CO2 Levels

2014-01-13· The accepted standard CO2 level in a classroom is 1000. That level is easy to maintain when a classroom is empty. Fill the classroom up with a bunch of students and the level of CO2 rises dramatically. That’s because carbon dioxide makes up a part of every breath you exhale causing the levels to rise as more people gather. “…increasing classroom ventilation rates, above the State ...

Measuring CO2 Inside Buildings - WSU Energy Program

a classroom during the first class of the day, CO 2 will not have accumulated to the point where equilibrium has been reached. Therefore, OSA ventilation rates based on this CO 2 measurement will be overestimated. If a CO 2 measurement is taken in the same classroom at the end of the day and the room’s ventilation rate and occupancy have remained fairly consistent throughout the day, it is ...

Why Measure Carbon Dioxide Inside Buildings?

2 measurement taken in the same classroom during the last period of the day. Assuming the ventilation rate and occupancy of the classroom have remained fairly consistent throughout the day, it is reasonable to assume that a CO 2 concentration below about 1,000 ppm indicates 15 cfm per person, assuming also that the outside air CO 2 is in the 350 ppm range (650 ppm differential inside minus ...

Overall, approximately 20% of the measured classroom CO2 concentrations were above 1000 parts per million (ppm), ranging from 352 to 1591 ppm. In multivariate analyses, the odds of reporting neuro-physiologic (, headache, fatigue, difficulty concentrating) symptoms among teachers significantly increased (OR = , 95% CI = ) for every 100 ppm increase in maximum classroom CO2 ...

This control strategy, which ... ventilation rate for a lecture classroom with a design population of 65 (Figure 1). ASHRAE 62-1989 through -2001 required 15 cfm of outdoor air per person in this space type. To comply, our example classroom must receive 975 cfm of outdoor air (15 cfm/ person × 65 people). If the population drops to 20, the required quantity of outdoor air drops, too, to 300 ...

CO2 In a Classroom – Indoor Air Quality

In Austria, building legislations state that CO2 amounts in a classroom should definitely not exceed 1,400 ppm. Normal outdoor CO2 concentration is in the range of 250-400 ppm; between 400 and 1000 ppm can be found in enclosed spaces that have good air exchange (ppm means “parts per million” and measures the mass of a chemical). Upwards of 1000ppm, causes drowsiness, and beyond 2000 ppm ...

CO2 Control In School Classrooms - AirTest Technologies

CO2 Sensors will automatically regulate fresh air delivery so that over-ventilation does not occur. In fact if fresh air is being delivered from another location such as an open window, hallway or another unoccupied classroom, the sensors will react to this source of fresh air and adjust the ventilation rate accordingly. CO 2 control is also an ideal way to control ventilation based on ...
