Overview

ISO 25745-2:2015/Amd 1:2023 is an important amendment to the international standard focusing on the energy performance of lifts (elevators). This update specifically addresses express zones-sections of a lift shaft where the distance between two adjacent stop floors exceeds three average floor distances. The standard provides refined methods for the energy calculation and classification of lifts, enhancing the accuracy of energy performance assessment and offering guidance for lift systems that incorporate express zones.

Developed by ISO Technical Committee ISO/TC 178 in collaboration with CEN/TC 10, this amendment fits within the broader ISO 25745 series on lifts, escalators, and moving walks. It supports sustainable building design and energy efficiency by offering standardized methods to calculate energy consumption relevant to lift operation, particularly in complex or high-rise buildings featuring express lift zones.

Key Topics

  • Express Zones Definition
    The amendment introduces a specific definition for express zones as lift well sections with greater than three average floor distances between landings, impacting energy consumption calculations.

  • Energy Calculation Formulas
    Two main formulas are established for calculating average travel distances:

    • For lifts without express zones, average travel is calculated based on the percentage of travel distances defined by usage categories.
    • For lifts with express zones, the formula accounts for the express zone length, the average floor distance, and the percentage of trips passing through the express zone.
  • Percentage Values
    Tables provide percentage values used in the calculations depending on lift usage categories and express zone lengths (e.g., ≤ 75 m or > 75 m), facilitating tailored energy assessments.

  • Multiple Express Zones
    When present, multiple express zones must be treated as a single combined express zone for calculation purposes.

  • Updated Symbols and Terminology
    New symbols such as k (percentage of trips through express zone) and s_ez (length of express zone) are introduced to clarify the calculation methods.

Applications

  • Building Design and Energy Modeling
    Architects and engineers can use this amendment to model and optimize energy consumption for high-rise buildings or complexes where express lifts are used, improving energy efficiency and sustainability.

  • Lift Performance Certification
    Manufacturers and installers can apply the updated calculation methods to certify lifts against energy performance benchmarks, ensuring compliance with the latest international standards.

  • Facility Management
    Building facility managers can better understand and predict lift energy consumption for operational cost management and environmental reporting.

  • Regulatory Compliance and Incentives
    The standardized approach aids compliance with energy codes and supports eligibility for green building certifications and government energy efficiency incentives.

Related Standards

  • ISO 25745-1:2012 – Energy calculation and classification methodology for lifts without the express zone amendments.
  • ISO 25745-3 – Energy performance assessment for escalators and moving walks.
  • ISO 25745 Series – Covers various aspects of energy performance, providing a comprehensive framework for vertical and horizontal transportation systems.
  • IEC Standards on Elevator Safety and Control – Supports electrical and operational safety in lift design complementing energy standards.

By incorporating ISO 25745-2:2015/Amd 1:2023 in their evaluation and design processes, stakeholders in the vertical transportation sector can achieve more accurate energy consumption measurements. This leads to enhanced energy efficiency, reduced operational costs, and meaningful steps toward sustainable building infrastructure.
