 Zusammenfassung: We summarize our three recent studies that determined CO2 emission rates from humans using the mass-balance model and the measured steady-state CO2 concentration. One study determined CO2 emission rates from sleeping adults; they were on average 11 L/h/person, 30-45% than for awake people at a light activity. They were relatively stable and similar to the published work and estimations using models. Two studies determined CO2 emission rates from the sedentary awake people at a light activity; they were on average 12.9-17.8 L/h/person. They were not significantly different between teenagers, young adults, and the elderly, nor when ozone and relative humidity increased. Reduced ventilation and increased CO2 significantly reduced CO2 emission rates; the changes in respiration could be the plausible reason. CO2 emission rates increased at thermal sensation departing from neutrality; increased metabolic activity could be the plausible reason. The emission rates were different from published results and estimations using models.
