  With the revision of the Building Standards Act in 2000, the Evacuation Safety Verification Act was introduced as a rule based on performance evaluation related to fire prevention and evacuation under the Building Standards Act. This evacuation safety verification method does not limit the evacuation route in the event of a fire in relation to the conventional specifications and the evacuation distance, but is a verification method related to performance design that verifies the ability to evacuate safely, regardless of the distance. is there.

  In other words, the evacuation safety verification method refers to the verification method for building evacuation safety performance specified in the notification of the Building Standards Act. The Building Standards Act basically defines specifications for evacuation safety. If the evacuation safety performance can be confirmed using the verification method, it is possible to plan based on performance design that is not bound by the specification rules. Specifically, the travel time from each place in the building to the evacuation destination is confirmed to be shorter than the descent time of the smoke generated by the fire, and it is verified that the building user can evacuate safely.

  The evacuation safety verification method is divided into three stages: (1) evacuation safety verification for each room, (2) evacuation safety performance verification, and (3) evacuation safety performance verification for the entire building. Among them, (1) evacuation safety verification for each room is performed at the initial design stage to verify the safety performance of room evacuation as shown in FIG. 4 in order to determine whether the verification method can be applied. For example, if the width of the door b of the room a is appropriately designed, the building user c can move out of the room (fire room) a without staying at the exit d, and the evacuation time is shortened. Evacuation can be safely performed outside the room. With such a design, the evacuation safety verification method can be applied.

  If the evacuation safety verification method (Standard Law Enforcement Ordinance) is applied and it is verified that it has evacuation safety performance, some provisions related to fire prevention and evacuation in the Building Standard Act can be relaxed. Thereby, the freedom degree of design can be improved, for example, lengthening the walk distance to the direct staircase (staircase room) e, or making a fire prevention area wide. In addition, the cost can be reduced by reducing the number of evacuation stairs, reducing the width of the stairs, reducing smoke exhausting facilities, and the like.

  However, in the evacuation safety verification method, (1) even if only evacuation safety verification is performed on a room-by-room basis, there are many conditions that can be set compared with the conventional design method, and these conditions are related to each other. However, there is a problem that it takes a lot of time to determine whether the evacuation safety verification method can be applied. For this reason, the evacuation safety performance itself cannot be determined quickly, and as a result, it takes time to design.

  In addition, if the evacuation safety verification method cannot be used because it takes a lot of time, etc., it is not possible to receive the benefits related to cost reduction and design freedom, which are benefits obtained by the verification method. There was a problem. Furthermore, as a result, even when the evacuation safety performance is satisfied, there is a problem that there is a possibility that the design is overdesigned because the margin is not known.

  The present invention was devised in view of the above-described conventional problems, and can be used to quickly determine whether or not the evacuation safety verification method can be applied to evacuation safety verification for each living room. Providing a display structure in the room evacuation performance design support system that can quickly determine the safety performance itself, and can take advantage of the verification method such as cost reduction and design freedom.
