The cooling and ventilation fan in the elevator machine room should be operated under the control of a temperature-controlled switch.
Promote walking movement, up and down within three floors as far as possible without taking the elevator.
When there are two elevators, they can be set to stop at alternate floors, one for the odd-numbered floors and the other for the even-numbered floors.
If there are several elevators, they can be set to operate at non-peak hours with fewer stops.
Lighting and ventilation inside the elevator should be cut off automatically after 3 minutes of standby.
