This paper is to report the revision of building codes in Japan towards harmonized regulatory system based on performance concept for fire safety. The building code of Japan covers passive fire protection systems such as fire resistance construction, limitation of wall lining materials and so on. At this moment, BSL is going to include more functional concept in replace of regulations based on the specifications of materials and constructions. So- called performance evaluation methods are going to be included to check the conformity with functional requirements for structural fire resistance and for egress safety. This paper summarizes BSL revision into functional statements.
