The ISO/DIS 25745-1 Reference Cycle: the ISO/ TC176/WG10 committee has been working on energy efficiency standards for some years and has published ISO/DIS 25 745-1 for comment. This standard specifies the measurement of the energy consumed by a lift when making a reference cycle. The ISO/DIS 25745-1 reference cycle obtains an energy expenditure value for the movement of an empty car from the bottom terminal floor to the top terminal floor and back to the bottom terminal floor, including door operations (or vice versa). The total energy consumed is made up of four components: 1 energy to travel from the bottom terminal floor to the top terminal floor; 2 energy consumed when the lift is stationary at the top terminal floor including that used to operate the doors; 3 energy to travel from the top terminal floor to the bottom terminal floor; 4 energy consumed when the lift is stationary at the bottom terminal floor including that used to operate the doors. The energy consumed per reference cycle is presented in mWh.
