Performance analysis-based fire safety design is one of the methods that helps to monitor the development of fire and its products propagation. This study presents a model that systematizes and facilitates the performance-based analysis processes in fire safety design of buildings. The model, whose system components are determined based on the system analysis method, consists of five stages. Pyrosim simulation program, which works as a user interface that includes FDS (Fire Dynamics Simulator) software was used to determine the changes in smoke propagation, visibility, temperature changes, and CO concentration. The designed model was applied to the patient bedroom storey of a hospital building, and the current situation and the situations after the suggestions for improvement were evaluated comparatively. Research results revealed that the basic parameters determining the fire environment are smoke propagation and visibility. In case of using smoke curtains and the smoke extraction fans, the smoke density decreases significantly with the increasing fan speed. In addition, the activation of the automatic sprinkler system is effective in reducing the temperature in the fire environment. Performance analysis-based design provides a basis for development and evaluation of fire protection measures based on the project's needs.
