From 2014 to 2017, through the cold season, 37 experimental measurements of carbon dioxide (CO2) concentration were done inside a selected university classroom, during the same type of activity, namely written examination. Based on the data obtained from the experimental measurements, the article sought to primarily establish a correlation between the body mass of the students and the intensity of carbon dioxide releases inside the experimental classroom. This relationship was determined by using statistical analysis (general least-square estimation of the regression line). The resulting equation may be used to determine in an easier way the required outdoor air volume flow rate inside a university classroom.
