Heat production from the human body vs. activity.
Activity and Human Metabolic Rates
|Laying down ||46 ||0.8 |
|Sitting, relaxed ||58 ||1.0 |
|Standing, relaxed ||70 ||1.2 |
|Sitting activity (office work, school etc.) ||70 ||1.2 |
|Standing activity (shop, laboratory etc.) ||93 ||1.6 |
|Moving activity (house work, working at machines etc.) ||116 ||2.0 |
|Harder activity (hard work at machines, work shops etc. ) ||165 ||2.8 |
The mean surface area of the human body is approximately 1.8 m2.
- Human physiology, air quality and comfort temperatures, activity and metabolic rates, health effects of carbon monoxide and more.
- Age and typical physical growth of boys and girls - age 2 to 18 years.
- Clo is used as a measure of clothes thermal insulation.
- Human metabolism at low and high activity with different levels of clothing.
- Composition of the human body.
- Heat gain from persons in air conditioned spaces - in btu/hr.
- Fresh air is required for respiration and for transport of heat and vapor emitted from the human body.
- Relaxation rest time vs. working time and activity.
- Metabiolic Rate - Met - is used as a measuring unit for human body heat or power production.
- Human metabolic heat gain in air conditioned rooms.
- Required air ventilation to handle odor and smell from persons.
- PMV index predicts mean comfort response of a larger group of people.
