ISO 25745-2:2015 specifies a method to estimate energy consumption based on measured values, calculation, or simulation, on an annual basis for traction, hydraulic and positive drive lifts on a single unit basis, and an energy classification system for new, existing, and modernized traction, hydraulic, and positive drive lifts on a single unit basis. It applies to passenger and goods passenger lifts with rated speeds greater than 0,15 m/s and only considers the energy performance during the operational portion of the life cycle of the lifts. For other types of lifts (e.g. service lifts, lifting platforms, etc.), it can be taken as a reference. It does not cover energy aspects, which affect the measurements, calculations, and simulations, such as the following: hoistway lighting; heating and cooling equipment in the lift car; machine room lighting; machine room heating, ventilation, and air conditioning; non-lift display systems, CCTV security cameras, etc.; non-lift monitoring systems (e.g. building management systems, etc.); effect of lift group dispatching on energy consumption; environmental conditions; consumption through the power sockets; lifts whose travel includes an express zone (an express zone is unlikely to affect the average car load but can significantly affect the average travel distance).
Abstract
Overview
ISO 25745-2:2015 - Energy performance of lifts, escalators and moving walks - Part 2: Energy calculation and classification for lifts (elevators) specifies a standardized method to estimate and classify the annual energy consumption of lifts. It applies to traction, hydraulic and positive drive lifts (passenger and goods-passenger) with rated speeds > 0.15 m/s on a single-unit basis. The standard focuses on operational energy (running, idle and standby) and provides a repeatable method based on measured values, calculation, or simulation.
Key technical topics and requirements
- Scope and exclusions
- Covers only operational energy (not manufacture, installation or disposal).
- Excludes non-lift energy uses such as hoistway lighting, car HVAC, machine-room HVAC, CCTV, building management systems, power sockets and group-dispatching effects.
- Energy calculation methodology
- Estimation of daily and annual energy consumption using measured, calculated or simulated inputs.
- Separate treatment of running energy (per trip, per metre, start/stop energy) and non-running energy (idle and standby modes).
- Handling of energy storage systems when used during normal operation.
- Measurement guidance
- Running energy can be measured using a terminal-to-terminal reference cycle or a defined short cycle as described in ISO 25745-1.
- Standby powers (5 min and 30 min) and component power-down sequences are taken into account.
- Energy classification
- Performance levels and an energy classification scheme for new, existing, and modernized lifts based on running and idle/standby metrics.
- Data handling and reporting
- Tools for data collection, example calculations and reporting templates are provided (including annexes with examples and symbols).
Practical applications
- Design and procurement: Compare lift options by estimated annual energy consumption to support low-energy specifications and tenders.
- Modernization and retrofits: Quantify expected savings from drives, controls, regenerative systems or standby improvements.
- Building energy audits & compliance: Provide a standardized basis for energy assessments and jurisdictional reporting.
- Manufacturer and installer validation: Verify declared energy performance and support commissioning measurements.
- Third‑party classification: Enable consistent energy labeling and benchmarking of single-lift units.
Who should use ISO 25745-2
- Building owners and developers
- Lift manufacturers and installers
- Maintenance and modernization service providers
- Energy auditors, consultants and architects
- Inspectors and certification bodies
