Energy Audit Types and Methodology Questions and Answers

Answer: C

A measure with an attractive return still loses to a project that expands capacity, because energy saving rarely has an internal champion with a revenue target. Ring-fencing a budget for energy measures is the usual organisational answer.

Answer: D

Correct answer: gives the measures a mandate that survives changes of personnel

A policy signed at the top settles in advance the arguments about priority that would otherwise be reopened at every level and after every reorganisation. It guarantees nothing about the savings and removes no requirement to justify a measure economically - what it does is ensure the case is heard rather than displaced by whatever is urgent that week.

Answer: A

A corrected set point is quietly changed back and a repaired leak reappears, so a measure verified once is not a measure that persists. Tracking a few indicators month by month is what keeps the savings from evaporating.

Answer: B

Starting from a record nobody disputes gives the total against which every later measurement must reconcile, and the seasonal pattern often points straight at the significant systems. That completeness is exactly why the bills come first.

Answer: C

Identifying opportunities quickly is exactly what it does well, and that is not the same as establishing savings a lender will finance. Capital decisions want measured figures with the risks quantified, which is the investment-grade audit's purpose.

Answer: D

The first and third are correct and both bear directly on whether an audit is acted upon. A nameplate states what a machine can do at its design point, and using it as a consumption figure overstates both the load and the saving from changing it.

Answer: A

Correct answer: 1 and 2 only are correct

Statements 1 and 2 are correct: the Bureau of Energy Efficiency was established under the Energy Conservation Act of 2001, and designated consumers in the notified sectors must appoint a certified energy manager and have audits conducted. Statement 3 confuses two instruments - energy saving certificates are earned under the Perform, Achieve and Trade scheme for exceeding an efficiency target, while renewable energy certificates represent renewable generation. They are traded separately and are not interchangeable.

Answer: B

Correct answer: establishing the resale value of the plant

Resale value belongs to an asset valuation, not to an energy audit. The three genuine objectives are all here and they follow in sequence: find where energy is being wasted, quantify what could be saved and what it would cost, and establish a baseline so that the improvement can afterwards be shown to have happened.

Answer: C

A gap of that size points at an unmetered load, a distribution loss or a measurement error, and closing it often finds the largest single opportunity on the site. Scaling the figures to agree conceals exactly what the audit exists to find.

Answer: D

Fixed loads such as lighting, compressors and ventilation continue whatever the output, so a plant running at half capacity uses more energy per tonne while using less in total. It is the standard reason a specific consumption figure must be read alongside the output.
