Abstract: This study investigates the Indoor Air Quality (IAQ) of a room apartment and focused on the number of occupants that a space or an apartment can accommodate as a result of increase in the concentration level of the CO2 contaminant present within the space. The law of mass action was applied to generate a relation between the concentration of CO2 produced and the concentration of the reactants (i.e., O2 and CO). A decay equation was also used to relate the variation in the number of occupants with the level of the concentration of CO2 within the space only at steady state conditions.

Keywords: contaminants; indoor air quality; room ventilation; concentration level; carbon dioxide; air pollution; mathematical modelling.
