We studied the changes in the concentration of total volatile organic compounds generated in newly-built schools (five kindergarten schools, two primary schools, three middle schools, one high school) by the bake-out. Samples were collected in classrooms. By using the bake-out technique the removal efficiency of total volatile organic compounds was 89.1%(maximum) and 27.5%(minimum). By using this bake-out technique the removal efficiency was 42.5% greater than the ventilation method. Therefore, we determined that it is appropriate to apply both the bake-out and ventilation methods in the case of newly-built schools
