SIST EN ISO 14414:2019 PDF

Overview

SIST EN ISO 14414:2019 / ISO/ASME 14414:2019 - Pump system energy assessment - defines requirements for planning, conducting, analysing and reporting a comprehensive pumping system energy assessment. The standard’s objective is to determine current energy consumption of existing pumping systems and identify opportunities to improve pumping system efficiency. It is intended for open and closed loop systems commonly found in industrial, institutional, commercial and municipal facilities, and is focused on electrically‑driven pumps while remaining applicable to other drivers (e.g., steam turbines, engines).

Key topics and requirements

• Assessment scope and team: identification of assessment team functions, structure, leadership, competency and facility management support. Annex C provides a body of knowledge for assessors.
• Assessment organization: defining objectives, boundaries, access to personnel/data, communications and scheduling.
• Assessment levels: tiered approach (Level 1, Level 2, Level 3) to match effort and data needs for pre‑screening through detailed analysis.
• Data collection & measurements: requirements for collecting system information and measured data - including pump and motor details, flow, pressure and input power - plus liquid properties and operational patterns.
• Analysis and cross‑validation: methods for analysing measured and historical data to quantify system energy demand and losses; Annex D gives recommended guidelines for analysis software.
• Reporting & action plan: requirements for documenting findings, recommendations and an action plan; Annex A details report contents.
• Informative guidance: examples of efficiency recommendations (Annex B), specific energy consumption metrics (Annex F), parasitic power (Annex G) and efficiency indicators (Annex H).
• Exclusions: the standard does not specify system design methods, implementation procedures, measurement/calibration techniques, financial costing, safety procedures, training/certification requirements, or address IP/security/confidentiality.

Practical applications and who uses it

This standard is used to organize and deliver structured pump system energy assessments to reduce energy use and operating costs. Typical users:

• Energy managers and sustainability officers
• Mechanical and process engineers
• Facility managers at industrial, municipal, commercial and institutional sites
• Energy consultants and third‑party auditors
• Utility program designers and incentives evaluators

Key outcomes include prioritized efficiency opportunities, quantified energy baselines, and documented recommendations/action plans for implementation.
