The worldwide energy crisis and the huge contradiction between China's energy demand and supply have attracted unprecedented attention, especially the industry which accounts for 1/3 of the total energy consumption. Elevator, as one of the essential vertical transportation tools for modern architecture, although its energy consumption generally accounts for only 3% to 8% of the total energy consumption of buildings, but the energy consumption of elevators has high energy saving potential and the advantage of improving space. It has been widely recognized worldwide. Recently, TUV SUD group (hereinafter referred to as the "TUV SUD") the relevant technical experts on the development of the industry, the German Association of engineers of VDI 4707 and the international organization for standardization ISO 25745 relates to elevator, elevator parts, escalator and autowalk energy efficiency certification has done a brief analysis.
In recent years, various international organizations have introduced different energy efficiency standards for elevator manufacturing. Among them, VDI 4707 is the most important part of the first part (whole machine) and the second part (parts), ISO 25745-1, ISO/DIS 25745-2 and ISO/DIS 25745-3. As a standard of energy efficiency, they have different emphasis on different products. Among them, the establishment and provides methods and procedures for energy efficiency evaluation and grading of elevator and parts of the part of the energy efficiency standards of VDI 4707 part and second, provide a benchmark for determining the calculation and components of elevator standby demand and operation needs, the standard for passenger elevator, elevator from the definition of EN81 and its components, can also be used in a similar lift. Take the second part of VDI 4707 (elevator component energy efficiency standard) issued in October 2013 as an example, it is aimed at components that can be completely used in working mode P0, S0, S1 and S2, and also applies to components needing further data description.
The international standardization organization ISO 25745 is suitable for all new, used or renovated elevators, escalators, and automatic sidewalks with a height of up to 8m and a level automatic sidewalk with a length of 60m. The energy efficiency standard ISO 25745-1 issued in October 2012 and the latest ISO/DIS 25745-2 and ISO/DIS 25745-3 issued in 2014 provide a measurement method for the actual energy consumption of elevators, escalators and automatic sidewalks. And the method of checking and checking the energy consumption of the elevator, the escalator and the automatic sidewalk in the use.
