Elevator room may have hi usage so most of the time we would provide air conditioning so just ventilation may not be adaquite. If only ventilation is needed then a good rule of thumb is 10 AC/hr.

If you know the manufacturer of the elevator, you can contact their technical sales rep and request equipment room heat gain information.

As I recall you should be able to get that info from the manfg of the equipment

Duct it to the hoistway, or have a fire dampered opening between the machine room and the hoistway.

New elevators because they use microprocessor controls have both temperature and humidity requirements. Thus we use air cooled ceiling hung computer room type AC units (with humidification & reheat o/& humidified ventilation air from a main AHU) that would run all the time. Get requirements from elevator manufacturer. Also get requirement on elevator shaft smoke venting.
