ABSTRACT
In a sports halls, where many athletes gather, the featured pollutant that is found in large quantities is CO2, seeing as it is inevitably generated by breathing (Ng et al. 2011).
In addition, teenagers are considered more vulnerable than adults are because their health is more susceptible to environmental pollution, as they are still under development (Freitas et al. 2011, Yang et al. 2009). As result of poor IAQ, student productivity (Braniš & Šafránek 2011, Jones et al. 2010), performance (Freitas et al. 2011), concentration and memory (Yang et al. 2009) can be seriously jeopardized.
