ISO 25745-3:2015 pdf free download – Energy performance of lifts, escalators and moving walks一 Part 3: Energy calculation and classification of escalators and moving walks.
a) a method to estimate energy consumption of escalators and moving walks on a daily and an annual basis for escalators and moving walks,
b) a method for energy classification of new, existing, or modernized escalators and moving walks,
c) guidelines for reducing energy consumption that can be used to support building and environmental and energy classification systems.
This International Standard is intended to be a reference for the following parties:
— building developers/owners to evaluate the energy consumption of escalators and moving walks;
— building owners and service companies when modernising installations including reduction of energy consumption;
— the installers and maintenance providers of escalators and moving walks;
— consultants and architects involved in specification of escalators and moving walks;
— inspecting authorities and other third parties providing energy classification services.
The total energy consumption over the entire life cycle of escalators and moving walks consists of the energy to manufacture, install, operate, and dispose of the lifts. However, for the purpose of this International Standard, only operating energy (running and standby) performance is considered.
In the preparation of this International Standard, Technical Committee ISO/TC 178/ WG 10 has initiated extensive research, which included the measuring and modelling of over 300 typical escalator and moving walk installations. The results of this research have been used to provide the numerical values shown in Table 3 and Table A.3.
This International Standard is suitable for national/regional jurisdictional energy performance purposes.
3.1 Terms and definitions
3.1.1
ancillary energy
energy used by the ancillary equipment
3.1.2
ancillary equipment
equipment such as lighting, fans, heating, alarm devices, emergency battery supplies, etc.
3.1.3
auto start condition
condition when escalator/moving walk is stationary and powered up and ready to start initiated by passenger detection
3.1.4
energy
power consumed over time
3.1.5
load condition
condition when escalator/moving walk is running with one or more passengers
3.1.6
no load condition
condition when escalator/moving walk is running at nominal speed without passengers
3.1.7
nominal speed of escalator/moving walk
speed in the direction of the moving steps, pallets, or the belt, when operating the equipment under no load condition (i.e. without persons), stated by the manufacturer as that for which the escalator or moving walk has been designed
3.1.8
power-off condition
power supply to the unit is turned off by the main switch, e.g. during the night
3.1.9
running-in period
required time to get mechanical components to best performance
3.1.10
slow speed condition
condition when escalator/moving walk is running at reduced speed without passengers
3.1.11
standby condition
condition when the escalator/moving walk is stationary and powered on and can be started by authorized personnel.
