Energy Performance That Can Be Demonstrated

Projects save energy only when the comparison is technically fair. A raw month-to-month reduction can be misleading if production, weather, product mix or operating hours changed.

Use the standards as a connected system

• ISO 50001:2018 provides the management-system requirements.
• ISO 50006:2023 guides evaluation using energy performance indicators and energy baselines.
• ISO 50015:2014 provides general principles for measurement and verification of organisational energy performance.
• ISO 50002-1:2025 provides general requirements and guidance for energy audits.

A defensible programme defines the energy boundary, significant energy uses, relevant variables, baseline period, data quality and normalization method before declaring improvement. Savings should be calculated using a method consistent with the intervention and supported by meter, production and operating records.
