초록

The management of airtightness of houses has been widely studied, while the airtightness of school buildings is still required to investigate. Therefore, the improvement action for the infiltration of fine dust is introduced in this paper. To measure the infiltration of fine dust, airtightness and indoor/outdoor fine dust concentration are obtained and then the infiltration path of outdoor fine dust concentration is identified at six schools in Busan, Korea. Then a series of experiments is conducted and provided following results. The average of amount of airtightness for target classroom is 14.9 ACH50 which is much higher than KIAEBS standard (5.0 ACH50) and ASHRAE commercial building standard (1.4 ~ 2.1 ACH50). The infiltration of school classroom is measured as following order, corridor window (61.3%), exterior window (27.9%), and mechanical ventilation (10.8%), meaning that a large amount of outdoor air is introduced from corridor wood windows and doors. The I/O ratio of PM 10 and PM 2.5 is increased when airtightness is getting worse. Consequently, it is found that the improvement of airtightness needs to be preceded to reduce indoor fine dust.
