The objective of this study is to present the future direction for the improvement of evacuation safety function by comparatively analyzing Korea and foreign standards, especially, the natural smoke exhaust system regulations of Japan that has the similar legal structure and operating system to Korea through the utilization of performance evaluation. For this, in the results of comparatively analyzing the current standards related to smoke exhaust system prescribed in construction statutes and enforcement regulations of both countries, there were differences in the installation distance, smoke ventilator effective area, smoke compartment, and installation size & use. Next, this study understood the influences of such differences on the actual performance through the performance evaluation called “evacuation safety verification method”. In the results of calculating the effective smoke exhaust volume(Ve) and smoke layer fall time(ts), there were huge differences in the results of performance evaluation according to the installed location of smoke ventilator and the matter of smoke compartment.
