I am really existing to receive your answer. I am new to this forum and to be very honest , I am new to fire protection engineering too. I am an elevator design engineer and interesting to study fire protection engineering.
This building is in Thailand. Thailand's code required pressurized lobby for fireman elevator. I am proposing to use 2 fireman elevators for evacuation (back-up).
Since we cannot pressurized all elevator lobbies the option is to pressurized elevator hoistways and build enclosed elevator lobbies at all floors except street level floor.
Do you think this is a good design?
