To execute the system practically, the labeling standards of some building performance (i.e. earthquake resistance, fire prevention, heat insulation, sound insulation, etc.) was promulgated on July the 19th in 2000, and this official system was started on Oct. the 1st. In this paper, we introduce the sound insulation standards of wall, floor and window opening of dwelling buildings (especially apartment buildings), that are regulated in this law.
