Energy Baselines & Performance Indicators
Provides guidance on establishing energy baselines, energy performance indicators, and the collection, analysis, and control of energy data to support ISO 50001 implementation.
ISO 50006 provides guidance on establishing energy performance indicators (EnPIs) and energy baselines (EnBs) as required by ISO 50001. It addresses the technical challenges of energy measurement and analysis, including normalisation for relevant variables such as production volume, weather, and occupancy.
The standard covers the full EnPI development process from data collection through statistical analysis to baseline adjustment, helping energy managers and auditors understand whether observed energy performance changes are real or simply reflect changes in operating conditions.
ACI-certified auditors apply ISO 50006 knowledge when evaluating the technical rigour of EnMS energy performance measurement systems under ISO 50001 audits.
Attend an ACI-Approved Training Provider (ATP) course for your chosen grade level. ACI-approved courses are aligned to the examination syllabus for ISO 50006.
Examinations are administered exclusively through ACI Approved Training Providers. Foundation and Internal Auditor examinations require 70% to pass; Lead Auditor requires 65%.
