Recently, the regulation about HEE(horizontally installed emergency exit) established at upper 4story in apartment houses was introduced by revising enforcement degree of Building Act. HEE is a facility for egress to lower story through floor breach and ladder system so that it gives a useful evaquation way directly to an individual household in apartment when they failed to evacuate through the entrance door. HEE may offer an opportunity to optain two way egress path ways instead of evacuation space at balcony and through path way to adjacent household in building and that might be an big strengh. but it needs to guarantee for against the crime, getting detailed reviews for being security and supplementation of fire test methods.

Evacuation facilities are installed so that people can evacuate high-rise apartment houses when it is impossible to escape fire through the front door. The households of apartment houses may escape the building in two ways, which will reduce loss of lives. This study examined the characteristics of two-way evacuation facilities, including a light-weight partition wall, shelter space at the balcony and horizontally-installed indoor emergency exit. Then, it proposed a horizontally-installed outdoor emergency exit that improved the problems of the examined facility types, and analyzed its economic-feasibility. When a horizontally-installed emergency exit instead of a traditional type to escape from fire is used, people may be more autonomous in deciding whether active evacuation is possible or not. Thus, the time required to evacuate the building with 4 different evacuation methods using the stairs and horizontally-installed emergency exit was simulated in consideration of the impact of evacuation methods that people choose on the time required for evacuation using pathfinder. Then, the simulation results were compared and analyzed. Any appropriate evacuation method to reduce the time required for evacuation was predicted, analyzed and decided. As a result of this study, it was analyzed that the high - rise apartment top - down type evacuation zone can shorten the total evacuation time compared to the staircase type.
