Abstract：
The outdoor design concentration of fine particles (PM2.5) is a significant design basis for air cleaning equipment configuration of building ventilation and air conditioning system. Discusses two typical methods at home for deciding PM2.5 outdoor design concentration. Presents the determination method of outdoor suspended particulates design concentration for public building air cleaning equipment selection in Japan. Proposes some suggestions for relative domestic code drawing.
