Abstract
Rising population growth and increasing land prices in large cities have led to an increase in the number
of high-rise residential buildings in recent years. These buildings have many challenges to evacuate the
population in case of emergency and fire due to factors such as a large number of residents, the possibility
of people sleeping, high height, etc. In the present study, the evacuation requirements and the related
challenges of the building from the perspective of architectural design have been investigated in fire
regulations in six countries: USA, Japan, France, Iran, England, and Australia. Then, the emergency exit
components were identified and evaluated. Also, the study of six types of residential units in the Ekbatan
town of Tehran revealed that the possibility of blocking the escape route of residential units is very high.
Therefore, considering the technological advances to save people in recent years and taking into account
the principle that the goal of safety is to save the lives of "all" people, it is proposed to design and
implement enclosed balconies in all units and with the capacity of that unit's resident, investigated and
required in the fire codes.
