Abstract

Carbon dioxide (CO₂) concentration has been used as a marker of ventilation effectiveness in the presence of people and as a marker of indoor air quality. CO₂ concentration indoors is a result of the rate at which outdoor air is supplied
indoors as well as the emission rate of CO₂. The main source of CO₂ indoors is humans. The emission rate depends on the metabolic processes and energy expenditure; other factors may affect production rate and respiration, such as temperature and elevated levels of pollutants, and consequently, the emission rate. There are methods to estimate the emission rates of CO₂ from humans. Still, there are limited data from actual measurements of emission rates from humans under controlled environmental conditions and metabolic rates. The present study filled this gap by estimating CO₂ emission rates from humans at the light activity. The study is a part of a larger project ICHEAR aiming at examining the emission rates from humans and their transformations in indoor environments.
