The building certification system has been the basis for improving building performance, and as demand has gradually diversified according to the changing conditions of the times, related certification types have also diversified. However, each building certification system and construction standards currently operated in accordance with the law which start from a unique purpose initially. The problem of overlapping additional functions has been raised as the operating period is prolonged, and itt is recognized as an obstacle.

In this study, the direction of maintenance and reorganization of the certification system that ultimately reflected the concept of smart architecture was set through various research methods and comparative analysis between building certification systems. To this end, a proposal for setting the integrated application direction of the smart building concept and recommendations for the direction of maintenance and reorganization of the overall certification system were derived.

In order to establish the direction of the integrated application of the smart building concept, the method through reorganization of the current certification system such as the green building certification and the intelligent building certification system was reviewed as an alternative. Also, the establishment of a new certification system was reviewed as another alternative.
