Energy Management Principles Questions and Answers

Answer: C

Correct answer: 3, 1, 4, 2

Plan is the energy review and the objectives that follow from it; Do is implementing the action plans and operating the controls; Check is monitoring the indicators and auditing the system; and Act is the management review deciding what to do next. Each stage supplies what the next needs, and the cycle closes when the review feeds a fresh set of objectives.

Answer: D

Analysing consumption and the variables that drive it locates where the energy goes and where it could be reduced, which is what everything downstream is planned against. It is the technical heart of the system and is repeated at defined intervals.

Answer: A

Either criterion admits a use to the list, so a modest consumer with a known large waste qualifies alongside the largest one. Everything that follows - controls, competence, monitoring - is concentrated on that list rather than spread evenly.

Answer: B

An indicator nobody can move is a report rather than a management tool, and one that moves with output rather than with performance misleads. Specific consumption for a particular use, normalised for its own driver, is the usual form.

Answer: C

A baseline is a reference, so it must be fixed long enough to compare against and revised when a change of process or product makes it meaningless. Recalculating it continuously would remove the very comparison it exists to provide.

Answer: D

Consumption normalised against the variables that genuinely drive it isolates the performance from the circumstances, which is what makes month-to-month comparison possible. Degree days and production volume are the two commonest.

Answer: A

Without a stated method of verification an objective can be declared achieved on assertion, which is how systems lose credibility. Naming the measurement in advance also settles arguments about the baseline before they arise.

Answer: B

Correct answer: broader statements of intent and targets are quantified

An objective states what the organisation intends - to reduce the specific energy consumption of the grinding plant, say. A target puts a number and a date on it: from 400 to 360 kWh per tonne by the end of the year. Without the target there is nothing to measure against, and without the objective the target has no purpose to serve.

Answer: C

Written criteria for compressor pressure, chilled water temperature or furnace excess air, and operation to them, are what stops performance drifting between one audit and the next. It is the clause that most directly preserves a saving.

Answer: D

Orientation, glazing, plant sizing and system architecture cannot be economically revisited once built, so a fortnight of attention at design outweighs years of operational effort. It is the highest-leverage clause in the whole standard.
