Standard core: first, test condition, unifying rated load, operation times, floor height, standby time test parameters, testing under standard environment of 25℃±2℃, voltage ±2%, ensuring data comparability; second, energy consumption calculation, dividing into three working conditions: no-load, half-load, full-load, calculating operation energy consumption, standby energy consumption, total energy consumption, unit kWh/1000 times; third, energy efficiency classification, divided into level 1 (ultra-energy-saving), level 2 (energy-saving), level 3 (qualified), level 4 (low-efficiency), level 1 energy consumption 40% lower than level 3, level 4 elevators prohibit new installation, rectification within time limit; fourth, verification requirement, third-party institution independent test, issue energy efficiency verification report, mark energy efficiency level, annual power consumption, carbon reduction, included in mandatory inspection items for elevator delivery, acceptance, maintenance; fifth, energy-saving benchmark, establishing national elevator energy efficiency database, enterprise energy efficiency ranking publicity, motivating technology upgrading. After implementation, average elevator energy consumption reduced by 25%, annual power saving over 12 billion kWh.
