Engineering ToolBox > Carbon Dioxide Emission from People
The carbon dioxide - CO2 - concentration in a room with people can be used as an indication of the ventilation systems efficiency. It's even possible to modulate the ventilation system capacity to the number of people and their activity by measuring the carbon dioxide concentration in the air.
The carbon dioxide emission from persons and their activity:
| Activity | Respiration per Person (m3/h) | Carbon Dioxide Emission per Person (m3/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 |
In a cinema with 100 persons at low to normal activity the emission of carbon dioxide will be in the range of 0.02 to 0.08 m3/h per person.
The total emission will be in the range of 2 to 8 m3/h.
