Abstract
This paper investigated pressure differentials in the elevator lobby depending on reference pressures of the pressurizing damper using FDS fire modeling. The results showed the temperatures and pressures in the contained fire room with small leak gaps can increase significantly. Setting reference pressure of the pressurizing dampers to 0 Pa can cause reduction of real pressure differentials and air velocity to resist smoke flow. This would cause smoke movement from fire room to elevator lobby which should be safe area for evacuation.
