ISO 50001:2018 Internal Auditor Training

Opens by asking whether a ten percent lower energy bill proves better energy performance. Walks through four real events: European gas prices above 340 euros per megawatt hour in August 2022 and BASF's February 2023 job cuts and ammonia plant closure at Ludwigshafen; Winter Storm Uri in Texas in February 2021; the revised EU Energy Efficiency Directive of September 2023 and its Article 11 thresholds; and the IEA's report of about 1 percent improvement in global energy intensity. Turns each into an auditor's question on context, the energy review, legal requirements and improvement against a baseline. Introduces Alder Pharma, a worked example of a generic medicines manufacturer in Toronto, and its three significant energy uses. Contrasts two audits of a chiller EnPI, one of which finds that the baseline was never normalized for weather. Explains ISO 50001:2018, clause 9.2, the course structure and four common myths.

Practice: Practice: The energy review part 2: SEU details · 3 questions

Starts with Alder Pharma's single indicator, total megawatt hours a month, which hid about 600 megawatt hours of compressed air leak savings because output rose. Explains the clause 6.4 requirements: indicators appropriate for measuring energy performance that enable improvement to be demonstrated, a maintained method, consideration of relevant variable data, and values compared with baselines and retained. Asks what action would make an indicator move. Matches an EnPI to each Alder Pharma SEU and gives four marks of good and poor indicators. Walks through measure, normalize, compare and retain for the chiller value of 0.78 kilowatt hours per ton-hour, and updating an indicator when a new chiller is added. Covers indicators outside SEUs, a New York office tower that models occupancy, and top management's role. Writes two findings, builds a boiler indicator, and ends with a Tokyo car-parts plant exercise.

What you will be able to do

• Check that indicator values are normalized where needed and compared with their baselines
• Assess whether the documented method leads to EnPI updates when an SEU changes

Why it matters

Ensures real savings show up in the numbers, so teams get credit for improvement and management sees true energy performance rather than output effects.

Practice: Practice: Energy performance indicators · 3 questions

Opens with a sister site that reset its compressed air baseline three times in eighteen months, each time to a high-consumption month, with no written rule. Explains clause 6.5: baselines from the energy review over a suitable period, normalization where data show relevant variables significantly affect performance, three revision triggers and retained records. Shows how Alder Pharma set its 2025 chiller baseline and compares sound and risky baselines. Uses a February 2021 Winter Storm Uri baseline in Texas to show why the period must be representative. Recalculates the site model, 480 expected against 456 actual megawatt hours, then a 900 thousand pack exercise. Covers public weather data, four questions for auditing a model, and the revision triggers: indicators that no longer reflect performance, major static factor changes and a pre-determined method. Uses a London university's revision, writes two findings, and ends with a Hong Kong laundry exercise.

What you will be able to do

• Assess whether a baseline period is suitable, representative and supported by retained data
• Recalculate expected versus actual energy from a normalization model and its data

Practice: Practice: Management review · 3 questions

Opens with Alder Pharma chillers found in the wrong order, reset and closed the same day, then wrong again three months later because nobody asked why. Explains the steps of clause 10.1: react and correct, evaluate the need to eliminate causes, implement, review effectiveness and change the system if necessary. Distinguishes correction from corrective action and follows a five whys analysis to a change process with no energy check. Shows why asking where else it could happen found another control logic error, and how energy data proved effectiveness six months later. Warns that human error is where analysis starts, not ends. Lists sources of nonconformities and ways to choose records to sample, and separates nonconformities from opportunities for improvement. Explains clause 10.2, continual rather than continuous improvement, ways to demonstrate it, a London retail chain's eleven percent fall, two findings, and a Singapore hotel exercise.

What you will be able to do

• Distinguish a correction from a corrective action that removes the root cause
• Check that corrective action records ask where else a nonconformity could occur
• Assess whether continual energy performance improvement is demonstrated across the scope

Why it matters

Stops repeat problems by testing that causes are found and removed, and that the organisation can prove its energy performance really improves.

Practice: Practice: Corrective action and improvement · 3 questions
