Abstract

Underground shopping center has become a important commercial facility due to their good accessibility to the public transport. However, underground shopping center has high risk of air contaminants emission like formaldehyde and lowered indoor air quality. In this study, formaldehyde concentration of the underground shopping center was estimated according to the renovation and characteristics of space. It was found that newly renovated underground shopping center has low formaldehyde concentration. In case of closed entrance type, the formaldehyde concentration was 320 % higher than open type. Formaldehyde concentration was varied by product type and especially, high formaldehyde concentration was measured near the stores selling nail polish and cosmetics. It is important to apply appropriate ventilation system according to characteristics of space.
