Question 1Fundamental principles and concepts of an Energy Management System (EnMS)
In ISO 50001, what does the term "energy performance" refer to?
- The total installed capacity of on-site renewable generation
- The monetary cost of purchased electricity per accounting period
- The number of energy audits completed during a certification cycle
- The measurable results related to energy efficiency, energy use and energy consumption Correct answer.
Explanation
Energy performance is a defined term covering measurable results tied to energy efficiency, energy use and energy consumption. It is broader than efficiency alone because it also captures consumption levels and use patterns, and it is the outcome the EnMS is designed to improve.
Question 2Fundamental principles and concepts of an Energy Management System (EnMS)
Which statement best describes the role of the energy management system itself, as opposed to an energy efficiency project?
- It is a purchasing contract for guaranteed energy savings
- It is a one-off technical retrofit of major energy-using equipment
- It is a set of interrelated elements used to establish energy policy and objectives and to achieve those objectives Correct answer.
- It is a reporting template submitted annually to the certification body
Explanation
An EnMS is a management system: interrelated or interacting elements such as processes, responsibilities and resources used to establish policy and objectives and to achieve them. Projects are outputs the system drives, not the system itself.
Question 3Fundamental principles and concepts of an Energy Management System (EnMS)
The ISO 50001 requirement for continual improvement of energy performance is best understood as:
- Repeating the same energy review each year without change
- Replacing the energy policy whenever a new manager is appointed
- Achieving a single absolute reduction target and then holding it
- Recurring activity to enhance energy performance and the EnMS over time Correct answer.
Explanation
Continual improvement is defined as recurring activity to enhance performance, and in ISO 50001 it applies both to energy performance and to the EnMS itself. It is a repeating cycle, not a one-time achievement or mere repetition of unchanged activities.
Question 4Fundamental principles and concepts of an Energy Management System (EnMS)
Under ISO 50001, who is responsible for ensuring the energy management system conforms to the standard's requirements?
- Only the designated energy management team representative
- Top management, which must demonstrate leadership and commitment Correct answer.
- Only the facility maintenance contractor
- Only the external certification body during surveillance audits
Explanation
Top management must demonstrate leadership and commitment, including ensuring the EnMS conforms to requirements and that intended outcomes are achieved. Responsibility can be delegated for operation but accountability remains with top management.
Question 5Fundamental principles and concepts of an Energy Management System (EnMS)
Which item is an example of an energy source rather than an energy use?
- Electricity used by a chiller plant
- Natural gas consumed by a boiler Correct answer.
- Compressed air supplied to a production line
- Steam distributed to a process
Explanation
Energy sources are the forms of energy that can be used or converted, such as natural gas, electricity, fuel oil or steam. The other options describe applications or uses of energy within equipment and processes.
Question 6Fundamental principles and concepts of an Energy Management System (EnMS)
What is the primary purpose of establishing an energy baseline in an EnMS?
- To document the organizational chart of the energy team
- To list the legal and other requirements applicable to the site
- To record the capital budget approved for energy projects
- To provide a quantitative reference against which energy performance changes can be compared Correct answer.
Explanation
An energy baseline is a quantitative reference providing a basis for comparison of energy performance, typically normalized for relevant variables. Without a baseline, changes in performance cannot be reliably demonstrated.
Question 7Fundamental principles and concepts of an Energy Management System (EnMS)
An energy performance indicator (EnPI) is best described as:
- A value or measure of energy performance agreed by the organization Correct answer.
- A legal limit on total site energy consumption
- A schedule of meter calibration dates
- A list of energy-using equipment in the asset register
Explanation
An EnPI is a measure or value of energy performance as defined by the organization, such as energy per unit of output. It is chosen by the organization and may be a simple ratio or a complex model.
Question 8Fundamental principles and concepts of an Energy Management System (EnMS)
Which of the following best expresses the Plan-Do-Check-Act logic embedded in ISO 50001?
- Plan the training, do the training, check attendance, act on feedback
- Plan the budget, do the spending, check the invoices, act on variances
- Plan energy objectives and processes, implement them, monitor results, and take action to improve Correct answer.
- Plan the audit, do the audit, check the audit, act on the audit
Explanation
The standard follows Plan-Do-Check-Act applied to energy management: establish objectives and processes, implement, monitor and measure against policy and objectives, and act to continually improve. The other options describe narrower administrative cycles.
Question 9Fundamental principles and concepts of an Energy Management System (EnMS)
A manufacturing site wants an indicator that reflects production-adjusted performance. It records monthly energy use and monthly tonnage. Which approach best produces a meaningful EnPI?
- Divide energy consumed by tonnes produced for each comparable period Correct answer.
- Use total annual energy consumption in kilowatt-hours as the indicator
- Report the percentage of the maintenance budget spent on energy
- Report the number of energy projects completed each quarter
Explanation
A ratio of energy to output normalizes for production volume, so changes in performance can be distinguished from changes in activity. Absolute consumption alone rises and falls with output and is a weak indicator.
Question 10Fundamental principles and concepts of an Energy Management System (EnMS)
A plant's energy baseline was set using 2019 data. Since then, a new production line changed the energy profile substantially. What is the most appropriate EnMS response?
- Delete the baseline and rely on monthly utility invoices only
- Replace the baseline with the single best month of performance
- Review and, where appropriate, adjust the baseline and normalize for relevant variables Correct answer.
- Keep the original baseline permanently because baselines must never change
Explanation
Baselines must remain relevant to the organization's operations, so significant changes in energy profile or relevant variables trigger review and adjustment. Normalization ensures comparisons remain meaningful after structural change.
Question 11Fundamental principles and concepts of an Energy Management System (EnMS)
During an energy review, a team identifies significant energy uses. What is the most defensible criterion for selecting them?
- Energy uses accounting for substantial consumption or offering substantial improvement potential Correct answer.
- Equipment located closest to the administration building
- Assets with the highest original purchase price
- Equipment that is newest in the asset register
Explanation
Significant energy uses are those accounting for substantial energy consumption or offering considerable potential for improvement. Selection should rest on energy data and improvement potential, not on age, location or capital cost.
Question 12Fundamental principles and concepts of an Energy Management System (EnMS)
An energy team is estimating future energy use. Which practice aligns with the energy review requirement to estimate energy use and consumption?
- Assume consumption stays constant regardless of planned expansion
- Rely only on the nameplate ratings of installed equipment
- Extrapolate from a single day of meter readings without adjustment
- Use historical consumption data and planned changes to model expected future use Correct answer.
Explanation
The energy review includes estimation of future energy use and consumption, which requires historical data combined with known and planned operational changes. Simple extrapolation or nameplate-only estimates ignore real operating conditions.
Question 13Fundamental principles and concepts of an Energy Management System (EnMS)
A warehouse installs submetering on its largest loads and begins tracking weekly consumption. Which EnMS principle does this most directly support?
- Replacement of the energy policy with meter readings
- Data-driven monitoring and measurement of energy performance Correct answer.
- Elimination of the need for management review
- Outsourcing of energy management to the utility
Explanation
Monitoring and measurement provide the data needed to evaluate energy performance against EnPIs and baselines. Submetering improves the granularity and reliability of that data, strengthening the check phase of the cycle.
Question 14Fundamental principles and concepts of an Energy Management System (EnMS)
Which situation best illustrates the concept of energy efficiency as distinct from energy consumption?
- A site switches from electricity to natural gas for space heating
- A site lowers thermostat setpoints during unoccupied hours
- A site delivers the same output while reducing kilowatt-hours per unit produced Correct answer.
- A site uses more kilowatt-hours because it added a second shift
Explanation
Energy efficiency relates output or service to energy input, so producing the same output with less energy per unit demonstrates improved efficiency. Increased consumption from higher activity is a volume effect, not an efficiency change.
Question 15Fundamental principles and concepts of an Energy Management System (EnMS)
An organization sets an energy objective to reduce energy per unit of product by 5 percent within two years. Which element makes this objective consistent with ISO 50001 expectations?
- It is stated only verbally by the plant manager
- It is measurable and has a defined time frame Correct answer.
- It covers all energy sources without any metric
- It is set by the supplier of the largest equipment
Explanation
Objectives should be measurable where practicable and consistent with the energy policy, and they are more useful when a time frame is defined. Measurability allows progress to be tracked against the EnPI and baseline.
Question 16Fundamental principles and concepts of an Energy Management System (EnMS)
Why does ISO 50001 emphasize normalization of EnPIs and baselines for relevant variables such as weather or production volume?
- To eliminate the need to collect energy data
- To make the numbers appear smaller in management reports
- To satisfy tax reporting obligations
- To separate changes caused by operating conditions from genuine changes in energy performance Correct answer.
Explanation
Normalization accounts for variables that legitimately affect energy use, so apparent changes caused by weather or output are not mistaken for performance improvement or deterioration. It protects the credibility of reported performance.
Question 17Fundamental principles and concepts of an Energy Management System (EnMS)
Which pair correctly matches an EnMS concept with its definition?
- Energy baseline: the organizational chart of the energy team
- EnPI: a legally binding emission limit
- Energy policy: a list of meter serial numbers
- Energy review: analysis of energy use and consumption based on measurement and other data Correct answer.
Explanation
The energy review is the analysis of energy use and consumption based on measurement and other data, leading to identification of significant energy uses and improvement opportunities. The other pairings attach unrelated content to defined terms.
Question 18Fundamental principles and concepts of an Energy Management System (EnMS)
A site's energy performance improved, but its EnMS procedures were not updated to reflect the new monitoring method. How should this be characterized?
- The EnMS improved while energy performance declined
- Energy performance improved, but the management system was not correspondingly improved Correct answer.
- Neither energy performance nor the EnMS improved
- Both energy performance and the EnMS improved equally
Explanation
ISO 50001 addresses improvement of both energy performance and the EnMS, which are related but distinct. Improved results without updated processes leave the system lagging behind practice, so the system has not improved in step.
Question 19Fundamental principles and concepts of an Energy Management System (EnMS)
Which activity belongs to the 'Check' phase of the PDCA cycle in an EnMS?
- Establishing the energy policy and energy review scope
- Conducting internal audit and evaluating energy performance against EnPIs Correct answer.
- Implementing operational controls on significant energy uses
- Defining energy objectives and action plans
Explanation
The Check phase covers monitoring, measurement, analysis, evaluation of performance and compliance, and internal audit. Policy, objectives and operational controls belong to Plan and Do.
Question 20Fundamental principles and concepts of an Energy Management System (EnMS)
A company wants to demonstrate that its EnMS delivers real energy performance improvement rather than only documented procedures. Which evidence set is most convincing?
- A complete procedure manual with signed cover sheets
- EnPI trends normalized for relevant variables, compared with the baseline, plus verified supporting data Correct answer.
- A list of planned projects with estimated savings
- A certificate of attendance for an energy awareness training session
Explanation
Demonstrating performance improvement requires measured results compared against the baseline, with normalization for relevant variables and reliable supporting data. Procedures and plans show intent and capability but not achieved performance.
Question 21Fundamental principles and concepts of an Energy Management System (EnMS)
An energy manager notes that absolute consumption fell by 8 percent while production fell by 20 percent. What does this most likely indicate about energy performance?
- Energy performance cannot be assessed under any circumstances
- Energy performance clearly improved because consumption fell
- Energy performance likely deteriorated because energy per unit of output rose Correct answer.
- Energy performance is unchanged because both values moved
Explanation
When consumption falls proportionally less than output, energy per unit of output increases, which indicates deteriorating performance on that indicator. Judging performance from absolute consumption alone would produce the opposite and incorrect conclusion.
Question 22Fundamental principles and concepts of an Energy Management System (EnMS)
Which statement about the relationship between the energy review and significant energy uses is most accurate?
- Significant energy uses are determined first and then the energy review is scoped around them
- The energy review is performed only after certification is granted
- The energy review analyses energy use and consumption and from that analysis significant energy uses are identified Correct answer.
- Significant energy uses and the energy review are unrelated requirements
Explanation
The energy review is the analytical process that produces, among other outputs, the identification of significant energy uses and relevant variables. Significance is therefore a result of the review rather than a precondition for it.
Question 23Fundamental principles and concepts of an Energy Management System (EnMS)
A site sets an EnPI as a simple ratio of energy to output, but output mix varies widely between high- and low-energy product families. What is the most significant limitation of this indicator?
- It may attribute performance changes to product mix shifts rather than to genuine efficiency gains Correct answer.
- It prevents the organization from setting any objectives
- It cannot be calculated from metered data
- It automatically violates legal compliance obligations
Explanation
A simple energy-per-output ratio assumes output is homogeneous; when product mix varies, the ratio can change because of mix rather than efficiency. A more suitable approach may use a model with relevant variables or separate indicators per product family.
Question 24Fundamental principles and concepts of an Energy Management System (EnMS)
Which scenario best demonstrates that an EnMS has changed organizational practice rather than only producing a document set?
- A consultant wrote the manual and the site stored it in a shared drive
- Energy criteria are embedded in procurement decisions and operational control procedures across departments Correct answer.
- An energy committee was formed but has not yet met
- The energy policy is framed and displayed in the reception area
Explanation
Embedding energy criteria into procurement and operational control shows the system is integrated into how the organization actually works. Displayed policies, externally written manuals and unformed committees indicate documentation or intent without changed practice.
Question 25Fundamental principles and concepts of an Energy Management System (EnMS)
An organization's energy performance improved during a period when production was unusually low due to a market downturn. What is the most rigorous way to interpret the improvement claim?
- Compare the period only against the single best prior month
- Test whether the change persists after normalizing for production volume and relevant variables Correct answer.
- Accept it unconditionally because the EnPI value fell
- Reject all energy data collected during downturns as invalid
Explanation
Lower activity can reduce consumption without any efficiency gain, so improvement claims must be tested against normalized expectations. Only changes that remain after accounting for relevant variables can be attributed to performance.
Question 26Fundamental principles and concepts of an Energy Management System (EnMS)
In ISO 50001, which element defines the boundary and scope within which the energy management system is applied, including the facilities, processes, and decisions the organization controls?
- The energy performance indicator
- The energy management system scope Correct answer.
- The energy review
- The energy baseline
Explanation
The scope statement fixes the physical and organizational boundary of the EnMS and identifies what is included and excluded, which then frames every later activity such as the energy review and baseline setting. The energy review, baseline, and EnPIs are elements applied inside that defined boundary, not the boundary itself.
Question 27Fundamental principles and concepts of an Energy Management System (EnMS)
An organization is deciding how to demonstrate continual improvement of energy performance. Which approach is most consistent with ISO 50001 principles?
- Recording the number of energy awareness training sessions delivered to staff
- Documenting the count of energy-saving projects completed each year
- Comparing EnPI values over time against the energy baseline, with normalization for relevant variables Correct answer.
- Reporting total annual energy cost reductions achieved through tariff negotiation
Explanation
Continual improvement of energy performance is demonstrated through comparison of EnPI values against the baseline, normalized for relevant variables so that changes reflect performance rather than external factors. Cost reductions, training counts, and project counts are supporting activities or outcomes but do not themselves evidence energy performance improvement.
Question 28Fundamental principles and concepts of an Energy Management System (EnMS)
A site identifies that compressed air is used across several production areas, and each area manager controls their own equipment. Which concept best explains why the compressed air system should be treated as a significant energy use requiring coordinated management?
- It is the system with the lowest maintenance cost in the plant
- It is the system that appears first in the equipment asset register
- It is the only system for which submetering data is technically available
- It is a major energy-consuming system whose performance is influenced by multiple decision-makers across the organization Correct answer.
Explanation
A significant energy use is a substantial energy consumption or opportunity for improvement that the organization can influence, and cross-cutting systems controlled by several parties are exactly the case where coordinated EnMS management adds value. Metering availability, maintenance cost, or asset-register order are administrative facts and not criteria for significance.
Question 29Fundamental principles and concepts of an Energy Management System (EnMS)
An energy manager compares two candidate EnPIs for a plant: one is total annual energy consumption in kWh, the other is energy per tonne of product normalized for ambient temperature. Which statement best reflects ISO 50001 thinking about choosing between them?
- The normalized intensity indicator is generally preferable because it accounts for relevant variables and better reflects performance Correct answer.
- The absolute indicator is preferable because intensity indicators cannot be compared against a baseline
- The absolute consumption indicator is preferable because it directly reflects the organization's environmental impact
- Both indicators are equally valid because ISO 50001 does not address normalization of indicators
Explanation
ISO 50001 expects EnPIs to reflect energy performance in a way that accounts for relevant variables affecting energy use, so a normalized intensity indicator usually gives a more meaningful signal than raw consumption. Absolute consumption can still be reported, but it moves with output and weather and so is a weaker measure of performance.
Question 30Energy Management System (EnMS)
Under ISO 50001:2018, which clause establishes the requirement to determine and have access to the legal and other requirements related to energy performance?
- Clause 9.1.2, evaluation of compliance
- Clause 6.1.3, determination of legal and other requirements Correct answer.
- Clause 7.5, documented information
- Clause 4.2, understanding the needs and expectations of interested parties
Explanation
The standard places the obligation to determine and provide access to legal and other requirements in clause 6.1.3, as part of planning actions to address risks and opportunities. Clause 9.1.2 then requires the organization to evaluate its compliance with those obligations at planned intervals.
Question 31Energy Management System (EnMS)
An organization is defining the scope of its energy management system. Which factor does ISO 50001:2018 require to be considered when establishing that scope?
- The number of employees at each production site
- The brand names of energy-using equipment purchased
- Its organizational boundaries and its ability to control energy performance Correct answer.
- The financial accounting standards applied to capital projects
Explanation
Clause 4.3 requires the scope to consider external and internal issues, legal requirements, and the organizational boundaries and the ability to control energy performance. Activities, products and services that are excluded must be documented and explained.
Question 32Energy Management System (EnMS)
What is an energy performance indicator (EnPI) under ISO 50001:2018?
- A financial index that converts energy use into currency
- A measurement or measure of energy performance as defined by the organization Correct answer.
- A legally mandated limit on annual energy consumption
- A third-party certification mark awarded for energy performance
Explanation
The standard defines an EnPI as a measurement or measure of energy performance, and the organization itself determines appropriate EnPIs. EnPIs allow the organization to demonstrate improvement, and they may be simple metrics or complex models.
Question 33Energy Management System (EnMS)
ISO 50001:2018 requires the organization to establish an energy baseline using information from which source?
- The capital budget approved for the current year
- An external consultant's benchmark database
- A forecast of future energy prices
- The initial energy review and, where relevant, data from measurement Correct answer.
Explanation
Clause 6.4 requires the energy baseline to be established using information from the initial energy review, and to be adjusted in case of significant changes. Data from measurement and other means are used to support this.
Question 34Energy Management System (EnMS)
Which activity is part of the energy review required by ISO 50001:2018?
- Selecting the certification body for the EnMS audit
- Benchmarking against competitor published sustainability reports
- Drafting the organization's public energy policy statement
- Identifying energy performance improvement opportunities Correct answer.
Explanation
Clause 6.3 requires the energy review to analyse energy use and consumption and to identify opportunities for energy performance improvement. It also covers identification of significant energy uses and relevant variables.
Question 35Energy Management System (EnMS)
What must an organization do with significant energy uses (SEUs) under ISO 50001:2018?
- Identify them and determine their relevant variables and performance Correct answer.
- Report them directly to the national energy regulator annually
- Outsource their operation to a certified third party
- Exclude them from the energy baseline to simplify accounting
Explanation
Clause 6.3 requires identification of SEUs, determination of relevant variables affecting them, and determination of their current energy performance. Appropriate action plans are then developed under clause 6.3 and 6.4.
Question 36Energy Management System (EnMS)
Which clause of ISO 50001:2018 requires top management to demonstrate leadership and commitment with respect to the EnMS?
- Clause 5.1 Correct answer.
- Clause 8.1
- Clause 9.3
- Clause 7.4
Explanation
Clause 5.1 sets out top management's leadership and commitment responsibilities, including establishing the energy policy and ensuring resources. It also requires top management to promote improvement and support other management roles.
Question 37Energy Management System (EnMS)
Which item is required content of the energy policy in ISO 50001:2018?
- A commitment to ensure the availability of information and necessary resources to achieve objectives Correct answer.
- A commitment to publish monthly energy performance data publicly
- A list of all energy-using equipment with purchase dates
- A commitment to purchase only renewable electricity by a fixed date
Explanation
Clause 5.2 lists required commitments, including ensuring availability of information and resources, and supporting the purchase of energy-efficient products and services. The policy must also be appropriate to the organization's purpose and provide a framework for objectives.
Question 38Energy Management System (EnMS)
An energy team is deciding how to express an EnPI for a paint line. The line's energy use varies strongly with production volume. Which approach best reflects ISO 50001 expectations for an EnPI?
- Report total site electricity in kWh per month with no normalization
- Report the energy price per kWh paid each month
- Track only the hours the paint line is switched off
- Use energy per unit of production and document the relevant variable Correct answer.
Explanation
When energy performance is affected by relevant variables such as production volume, the EnPI should be normalized so it reflects performance rather than activity level. The chosen relevant variable and the method should be documented.
Question 39Energy Management System (EnMS)
A plant's energy baseline was set for 2019. In 2023 it added a new production hall that more than doubled output. What does ISO 50001:2018 require regarding the baseline?
- Discard all historical data and restart the EnMS from scratch
- Report the change only to the certification body without internal action
- Adjust the baseline or EnPIs in response to the significant change, keeping information documented Correct answer.
- Nothing; baselines must remain fixed for the life of the EnMS
Explanation
Clause 6.4 requires that the energy baseline be adjusted in the case of significant changes affecting energy performance, and that information be retained. Normalization and adjustment should be done in a documented, consistent way.
Question 40Energy Management System (EnMS)
During an internal audit, a finding notes that the organization identified significant energy uses but never established objectives or action plans for them. Which clause is most directly unfulfilled?
- Clause 7.2, competence
- Clause 4.4, energy management system
- Clause 9.2, internal audit
- Clause 6.2, objectives and planning to achieve them Correct answer.
Explanation
Clause 6.2 requires objectives to be established at relevant functions and levels, and planning to achieve them, including what will be done and by when. SEUs identified in the energy review should feed into these objectives and action plans.
Question 41Energy Management System (EnMS)
A company wants to claim energy performance improvement in its EnMS. Which combination best supports a credible claim under ISO 50001:2018?
- Anecdotal reports from operators and a single utility bill comparison
- Installation of new equipment without any measurement
- Comparison of EnPI values against a baseline, using data from measurement and analysis Correct answer.
- A statement in the energy policy that improvement has occurred
Explanation
Clause 9.1 requires monitoring, measurement, analysis and evaluation of energy performance against EnPIs, and comparison against the baseline where relevant. Improvement claims should be supported by consistent, measured data.
Question 42Energy Management System (EnMS)
Which activity belongs to operational planning and control under clause 8.1 of ISO 50001:2018?
- Establishing criteria for the effective operation of significant energy uses and controlling processes accordingly Correct answer.
- Selecting the internal audit team
- Determining the competence needs of energy team members
- Reviewing the suitability of the energy policy
Explanation
Clause 8.1 requires the organization to plan, implement and control processes needed to meet EnMS requirements, including establishing criteria for effective operation of SEUs. It also covers control of outsourced processes and design activities affecting energy performance.
Question 43Energy Management System (EnMS)
Under ISO 50001:2018, what is the purpose of the management review?
- To certify the organization's energy performance for external stakeholders
- To set national energy efficiency targets
- To replace internal audits when resources are limited
- To ensure the EnMS remains suitable, adequate and effective and to identify opportunities for improvement Correct answer.
Explanation
Clause 9.3 requires top management to review the EnMS at planned intervals to ensure its continuing suitability, adequacy and effectiveness. The review considers inputs such as energy performance, audit results and compliance status, and produces decisions on improvement.
Question 44Energy Management System (EnMS)
An organization discovers that a contractor operating a boiler house is not following agreed energy procedures. How should this be handled within the EnMS?
- Control the outsourced process through operational control requirements and agreements Correct answer.
- Wait for the next certification audit to raise it
- Ignore it because contractors are outside the EnMS
- Remove the boiler house from the EnMS scope
Explanation
Clause 8.1 requires the organization to control planned changes and to ensure that outsourced processes are controlled or influenced. Contracts or agreements with contractors should specify energy performance expectations.
Question 45Energy Management System (EnMS)
Which of the following best describes the relationship between the energy review and the energy baseline?
- The baseline is created first and then the energy review is derived from it
- The baseline replaces the need for an energy review
- The two are unrelated processes
- The energy review informs the establishment of the baseline and EnPIs Correct answer.
Explanation
Clause 6.3 requires an energy review, and clause 6.4 requires the baseline to be established using information from that review. EnPIs are also determined using this information, so the review precedes and informs the baseline.
Question 46Energy Management System (EnMS)
An energy manager wants to ensure that energy performance is considered in design of a new facility. Which clause of ISO 50001:2018 is most relevant?
- Clause 7.3, awareness
- Clause 4.1, understanding the organization and its context
- Clause 8.2, design Correct answer.
- Clause 9.1.1, monitoring and measurement
Explanation
Clause 8.2 requires the organization to consider energy performance improvement opportunities and operational control in the design of new, modified or renovated facilities, equipment, systems and processes. The results of the design activity should be documented.
Question 47Energy Management System (EnMS)
What does ISO 50001:2018 require regarding energy performance indicators and the energy baseline when monitoring and measuring?
- They must be reported to the public annually
- They are optional once initial certification is achieved
- The organization must analyse and evaluate energy performance against them at planned intervals Correct answer.
- They must be reviewed only when certification is renewed
Explanation
Clause 9.1 requires the organization to analyse and evaluate energy performance at planned intervals, comparing EnPI values against the baseline where relevant. This evaluation supports corrective action and management review.
Question 48Energy Management System (EnMS)
An organization must determine the competence of persons whose work affects energy performance. Which action best fulfils clause 7.2?
- Determining necessary competence, ensuring persons are competent, and retaining documented evidence Correct answer.
- Distributing the energy policy leaflet at induction
- Posting energy awareness posters in the canteen
- Providing training only when an employee requests it
Explanation
Clause 7.2 requires the organization to determine the necessary competence of persons doing work under its control that affects energy performance, ensure they are competent, and retain appropriate documented information as evidence. Actions can include training or mentoring.
Question 49Energy Management System (EnMS)
A company sets an objective to reduce energy consumption per tonne of product by 5% within two years. What must accompany this objective under clause 6.2?
- A public press release announcing the target
- An immediate update to the energy baseline without any analysis
- A planning document stating what will be done, resources required, responsible persons, timeframe and how results will be evaluated Correct answer.
- A guarantee that the target will be met regardless of production changes
Explanation
Clause 6.2 requires planning for how objectives will be achieved, including what will be done, what resources are needed, who is responsible, when it will be completed and how results will be evaluated. Objectives should also be measurable where practicable.
Question 50Energy Management System (EnMS)
During management review, data show that an EnPI has worsened against the baseline despite an action plan. What is the most appropriate EnMS response?
- Extend the baseline period until the result improves
- Investigate the cause and take corrective action, considering changes to relevant variables or actions Correct answer.
- Remove the EnPI from the monitoring plan to avoid a negative result
- Conclude that ISO 50001 offers no benefit and withdraw
Explanation
Clause 10.2 requires the organization to react to nonconformity, evaluate the need for action to eliminate the cause, and implement corrective action. Worsening performance against an EnPI is a signal to investigate, not to remove the indicator.
