Elevator energy code requirements
Energy is often at a premium in cities, with around 45 million passenger journeys taking place every day. There is a high potential for inefficient use of electricity, which is harmful to the environment and potentially dangerous to the rider. The opportunity to regain potential energy was also missed.
Lighting Efficiency: If you divide the lumens for interior cab lighting by watts per watt. The amount of visible light produced must be greater than or equal to 35 lumens per watt.
Ventilation fan power: Ventilation fan power consumption cannot exceed 0.33 watts per cubic foot per minute (cfm) when the elevator car is not air-conditioned.
Power outage control: If the elevator is stopped and unoccupied and the doors are closed for more than 15 minutes, the elevator must automatically turn off interior lighting and ventilation.
Elevator operation can also use power conversion technology to recover energy. New traction elevators in new buildings with heights of 75 feet or higher must meet the following standards:
Motor type: Elevators must be equipped with an induction motor with an IE2 efficiency rating, or an approved alternative motor such as a gearless traction machine.
Efficiency: For elevators with Class IE2 motors and a capacity of less than 4,000 pounds, power transmission between the motor and moving parts does not reduce the overall efficiency. At the same time, gearless machines must maintain 100% transmission efficiency at all times.
Regeneration: The elevator must have a regenerative drive that recovers the potential energy released when the elevator moves and provides it to the building's electrical system (like the brakes on a hybrid car).
