Carbon Dioxide Human Gains—a New Approach of the Estimation

Antonio Rodero , Dorota Krawczyk


Human health is dependent on the Indoor Air Quality (IAQ) of residential and public buildings, where people spend a substantial amount of time. Part of IAQ parameters, like temperature or humidity influence the thermal comfort of users, whereas too high carbon dioxide concentration (CO2) could cause various complaints or diseases. In buildings like offices and schools, where we have a brush with a high density of users, the main source of CO2 is simply people. The type of their activity brings higher or lower carbon dioxide gains, that must be taken into account to design and properly use room ventilation, allowing recommended CO2 levels not to be exceeded. This paper presents an approach to marking human CO2 generation off by using an experimental method. The method was verified based on measuring results of six test series conducted in different types of rooms at Bialystok University of Technology (Poland) during lectures, meetings, projects and laboratories. Carbon dioxide gains were comparable with an average value of 0.0045 L/s, which corresponds to theoretical CO2 generation rates that are symptomatic of males and females, between 16 and 30 years old, with low physical activity.
