The impact of Top on A SVs decreases with an increase in CO2 levels, and the effect of CO2 levels on ASVs decreases with increase in Top. The most favorable ASVs are given when children feel “cool” and have “as it is” preference. By keeping CO2 < 1000 ppm and Top within children's thermal comfort band, ASVs are improved by 43%. The study recommends that standards should consider the impact of both
temperature and CO2 levels on perceived IAQ. Perception of IAQ also affects children's
overall comfort and tiredness levels; however, this influence is more significant
on tiredness level than that on overall comfort level.
