Co2 Persons
Reference data and engineering information about co2 persons for physiology applications.
Overview
Engineering reference data for Co2 Persons in physiology.
Key Formulas
Basal Metabolic Rate
Kleiber's law — metabolic rate scales with body mass.
Heat Loss
Convective heat loss from body.
Variables
| Symbol | Description | Unit |
|---|---|---|
| Heat loss | W | |
| Heat transfer coefficient | W/(m²·K) | |
| Body surface area | m² |
CO2 Emission by Activity
The rate of carbon dioxide (CO₂) production from occupants is a function of their metabolic activity level. This data is essential for calculating ventilation requirements and indoor air quality.
Activity | Respiration per Person(m³/h) | CO₂ 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 |

Note: The respiration and emission values are given in ranges for activities that vary in intensity. The total CO₂ load in a space is the sum of the emissions from all occupants. For example, in a cinema with 100 people in low to normal activity, the total CO₂ emission would range from 2 to 8 m³/h.
