Investigation of CO production depending on physical activity of students.

This paper aims to carry out measurements of indoor air temperature, relative humidity and carbon dioxide (CO) concentrations as well as to determine CO production by students and teacher during various physical activities. Two classrooms of Technical University of Kosice were selected for the research. Results of objective measurements confirmed strong correlation between CO concentration occupancy for all measurements.

The influence of occupants' body mass on carbon dioxide mass flow rate inside a university classroom - case study.

From 2014 to 2017, through the cold season, 37 experimental measurements of carbon dioxide (CO) 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).
