Ebert Gerry Fitzmaurice Steve Miller, City of Everett SUBJECT: ELEVATOR PRESSURIZATION I have talked with Steve Miller at the City of Everett and they use the UBC with the State Amendments for elevators and lobby exceptions. A hotel building requires that the elevators be separated from the corridors by a rated lobby with a rated door, or a rated door at the elevator shaft opening (Won -door or similar), or by the use of pressurization. We would like to pressurize the shaft due to it's short height and the pedestrian flow through the corridors. Please be sure that the design/build specs (Both mechanical and electrical) call for pressurization of the elevator shaft per Section 905 of the 1994 UBC. Our intent is for the fan to sit on top of the elevator shaft under the curved roof and have an intake duct to the side wall on the east. Gerry Fitzmaurice will coordinate the eleancal requirements and the interface with the fire alarm system in his design/build spec. Steve Miller said that the City of Everett would not require that the elevator machine room be pressurized. The UBC requirement for this seems tied into the high rise code and is not intended for a building of only three stories where the pressurization is being used to waive the lobby requirement. The elevator shaft does not need to be vented since we are only going through two floors. This means that there does not have to be an interface between operation of the pressurization fan and the vent louver.
