Abstract

Formaldehyde and volatile organic compounds (VOCs) emitted from finishing materials and paints in newly constructed buildings can contribute to sick building syndrome, posing greater health risks to children with underdeveloped immune systems. This study employed the indoor air quality simulation tool CONTAMW to evaluate flush-out effect for formaldehyde and toluene in a nursery room of a newly built daycare center. The simulation results showed that HCHO concentrations were reduced by 10–24%, and toluene by 48.0–78.7%, depending on the flush-out conditions. Moreover, extended flush-out periods with lower air change rates were more effective in reducing pollutant concentrations. These findings offer insights into effective ventilation strategies for preventing symptoms of sick building syndrome and are expected to serve as foundational data for managing indoor air quality in newly built daycare centers, which are not yet subject to mandatory measurement.
