Fine dust is known to cause various Respiratory disease and affects human health. Modern people spend 80% of the day living indoors, which means that indoor air quality has a great influence on humans. In particular, infants and children are very vulnerable to the environment. In this study, under the assumption that the fine dust of the outside air is higher than that of the indoor, the inflow of external fine dust is to be prevented through architectural improvement of the school building. As a method of reducing fine dust, an experiment was conducted by adopting a strategy to improve airtightness. The building is a five-story school building, and experiments are conducted in a special classroom. Airtightness performance is measured according to the standard of ISO 9972. In addition, thermal imaging cameras are taken for each construction part and wind speed is measured. To improve the airtight performance, the frame is changed from a single window to a double window. In addition to changing the frame, subsidiary materials for construction were installed to improve airtightness. As a result of architectural improvement, ACH was reduced by 19 to 37%. Wind speed is also reduced by up to 1.2m/s after window improvement. The concentration of fine dust was decreased the most from 0.3 to 0.5 μm. This means that the influence of fine dust introduced from the outside is reduced by improving the airtightness in the fine dust particle size of 0.3 to 1.0. Based on the result of the reduced fine dust concentration, the appropriateness of the indoor fine dust concentration in school facilities was evaluated. Through this research, it is effective to block the inflow of external fine dust through trench replacement and airtight performance improvement technology.
