Fire rating of elevator shaft/enclosure in 2 story building B-occupancy (IBC 2006)

[AegisFPE]

The problem arose where the code requires the machine room to have the same rating as the shaft. In this case it is a Kone Econo Space elevator which has the machine in the elevator shaft (at the top) with a "control closet" located on the second floor.

I agree that the elevator shaft is to be of fire-resistance-rated construction. However, this sounds like a "machineroom-less" system, such that there is no machine room. With the elevator equipment in the hoistway, it is already appropriately separated from the building.

Either the control closet should either be separated from the hoistway or the building (if open to the hoistway). I don't agree that the code requires the control closet to carry the rating of the elevator shaft.

You need to read ASME 17 .. that's the elevator code. You will find ALOT of requirements for the control room/controller in there.

Peach: I agree with the reference to ASME 17 when enclosed.

Thank you all for the responses.

Opinions and clonclusions seem to vary.

If the elevator code is the driving factor maybe the IBC should simply state that all "elevators are to be in accordance with ASME 17"
