Abstract:
A method of controlling an elevator system having an elevator car for serving hall calls at floors of a building comprising the steps of:a. selectively operating an elevator drive means coupled to an elevator car in a high performance mode to move the elevator car to serve hall calls at floors in a building;b. selectively operating the elevator drive means in an energy conservation performance mode to move the elevator car to serve the hall calls; andc. sensing an actual value of at least one predetermined condition and, in response to said actual value of each said predetermined condition, selectively operating the elevator drive means in said energy conservation performance mode during an associated one portion of a movement of the elevator car from one floor to another floor and in said high performance mode during another portion of the same movement of the elevator, wherein said one predetermined condition is wind speed and said associated one portion is during a constant velocity travel of the elevator car.
