Carbon Dioxide - CO can be used to indicate ventilation system efficiency. It is even possible to modulate ventilation system capacities to the number of people and their activities by measuring the carbon dioxide concentration in the room air. 2 - concentration in a room with people
Carbon dioxide emission from persons and their activity:
Carbon Dioxide Emission from the Human Body vs. Activity Activity Respiration per Person (m 3/h) Carbon Dioxide Emission per Person (m 3/h) Sleep 0.3 0.013 Resting or low activity work 0.5 0.02 Normal work 2 - 3 0.08 - 0.13 Hard work 7 - 8 0.33 - 0.38 1 m 3/h = 0.5886 ft 3/min (cfm) Example - Carbon Dioxide Emission from Persons in a Cinema
In a cinema with
100 persons with low to normal activity the emission of carbon dioxide is in the range 0.02 to 0.08 m per person and the the total emission will be in the range 3/h 2 to 8 m. 3/h Related Topics Human physiology, air quality and comfort temperatures, activity and metabolic rates, health effects of carbon monoxide and more.
