RATIONALES
1. A large hospital is establishing its Energy
Management System (EnMS) for the first time. The
energy team has completed an energy review and
identified that the HVAC system accounts for 45% of
total energy consumption. However, they have not
yet defined what “significant energy use” (SEU)
means. **Which statement best describes a valid
approach to defining significance under ISO
50001?**
A) Significance must be defined solely by the
organization’s total annual energy cost
B) The organization must establish its own criteria for
significance, which may include factors such as
energy consumption magnitude, potential for
improvement, or operational criticality
C) ISO 50001 prescribes that any energy-consuming
system accounting for more than 20% of total
consumption is automatically an SEU
,D) The definition of significance must be approved by
an external certification body before implementation
Correct answer: B
Rationale: Clause 6.3 requires organizations to define
criteria for significance based on their own context.
There is no fixed percentage threshold in the
standard. The organization must determine what is
“significant” to it.
2. A chemical plant has established an energy
baseline (EnB) using data from a 12-month period.
During the baseline period, the plant operated at 70%
of its rated production capacity. In the current year,
capacity utilization has increased to 90% due to
market demand. The energy team uses “kWh per
tonne of product” as its primary EnPI. **Which
statement is most accurate regarding the validity of
the baseline and the EnPI?**
A) The baseline is invalid because capacity utilization
changed; a new baseline must be established
B) The baseline is still valid because “kWh per tonne
of product” is a normalized EnPI that accounts for
changes in production volume
C) The baseline must be adjusted only if the change in
capacity utilization exceeded 25%
,D) The baseline should be updated only if the
organization replaced major energy-using equipment
Correct answer: B
Rationale: Clause 6.4 requires consideration of
relevant variables. Using a ratio EnPI (kWh/unit)
normalizes for production volume, making the
baseline valid even when production changes.
3. An energy manager is training new staff on the
Plan-Do-Check-Act (PDCA) cycle within the context of
ISO 50001. **Which activity belongs to the “Check”
phase of the PDCA cycle?**
A) Establishing the energy policy and setting energy
objectives
B) Implementing operational controls for SEUs
C) Conducting internal audits and analyzing EnPI
trends
D) Taking corrective actions to address
nonconformities
Correct answer: C
Rationale: The “Check” phase involves monitoring,
measurement, analysis, evaluation, internal audits,
and management review. The other options belong to
Plan (A), Do (B), and Act (D).
, 4. A manufacturing company has identified a
compressed air system as a significant energy use
(SEU). The energy team has implemented an action
plan to reduce leaks, which includes weekly leak
detection surveys and prompt repairs. During a
surveillance audit, the auditor notes that the leak
detection log has several entries marked “deferred
due to production schedule.” **What is the most
appropriate audit finding?**
A) No finding, because the organization is aware of
the leaks and plans to address them
B) Major nonconformity, because the SEU is not
being effectively controlled
C) Minor nonconformity, because the organization is
not following its own operational control procedure,
and the root cause should be investigated
D) Observation, because leak detection is not a
regulatory requirement
Correct answer: C
Rationale: The organization is not following its
documented operational control. However, the
deviation is not systemic, so it is appropriately
classified as minor pending root cause analysis.
