Question 1

Electricity at a packaging plant rose from 90,000 kWh in a reference month (20,000 acceptable units; 100 cooling degree-days) to 108,000 kWh this month (30,000 acceptable units; 200 cooling degree-days). Its validated baseline model is E = 40,000 + 2P + 100C, where E is monthly kWh, P is acceptable units, and C is monthly cooling degree-days. The model is valid for both months, required service is unchanged, and no other adjustments apply. Against a target of at least 8% normalized reduction, how did this month perform?

Accepted Answer

10.0% improvement; the target was achieved.

Answer

20.0% deterioration; the target was missed.

Answer

1.8% improvement; the target was missed.

Answer

11.1% improvement; the target was achieved.

Question 2

At six supermarkets, HVAC operating schedules repeatedly revert to continuous operation after servicing. The settings have been restored and technicians retrained twice. Investigation finds that necessary after-hours tests use overrides with no expiry, and the service procedure contains no restoration check. Which corrective action addresses the demonstrated cause?

Accepted Answer

Implement authorized, time-limited overrides and verify automatic restoration at all six stores after maintenance.

Answer

Restore the schedules again and close the finding after one day of normal operation.

Answer

Require new training acknowledgments and close the finding when every technician has signed.

Answer

Prohibit all after-hours testing, including the tests required to maintain the equipment safely.

Question 3

After rooftop photovoltaic panels are installed at a retail distribution center, grid electricity purchases fall by 25%. Separate meters show that total electricity supplied to the site's end uses is unchanged at the same throughput and operating conditions. The owner describes the result as a 25% improvement in end-use energy efficiency. Which interpretation is defensible?

Accepted Answer

Purchased electricity fell; an end-use efficiency gain has not been demonstrated.

Answer

The reduction in purchased electricity establishes an equal improvement in end-use energy efficiency.

Answer

Photovoltaic output should be deducted from measured end-use consumption before efficiency is assessed.

Answer

The efficiency claim becomes valid when exported photovoltaic electricity is included in the comparison.

Question 4

A conventional evaporative cooling tower runs its fans at full speed while trying to meet a 21°C leaving-water setpoint. Independent measurements confirm an entering-air wet-bulb temperature of 24°C and leaving water at 29°C. At the measured heat load and water flow, the manufacturer's performance curve predicts 29°C leaving water. There are no protective alarms. Which assessment accounts for all these findings?

Accepted Answer

The tower is performing as predicted; a conventional evaporative tower cannot reach the requested temperature.

Answer

Heat-transfer failure is established; take the tower out of service for inspection.

Answer

Insufficient controller gain is preventing the tower from reaching a feasible setpoint.

Answer

Additional tower capacity is needed to achieve 21°C at the measured wet-bulb temperature.

Question 5

A factory's documented criteria identify a significant energy use (SEU) when it accounts for at least 15% of site energy OR has technically supported savings potential of at least 25 MWh/year. Compressed air accounts for 8% of site energy and offers 40 MWh/year of supported savings. The proposed improvement has a seven-year payback, outside the factory's three-year investment criterion. How should the energy review treat compressed air?

Accepted Answer

Classify it as an SEU; assess project approval separately against the investment criterion.

Answer

Defer SEU classification until the proposed project satisfies the three-year investment criterion.

Answer

Exclude it from SEU classification because its consumption share is below the stated threshold.

Answer

Classify it as an SEU and approve the project despite the stated investment criterion.

Question 6

Diesel for an emergency generator represents only 1% of a warehouse's annual energy consumption. The organization controls the generator, and its documented EnMS scope includes all activities and energy-using equipment within the warehouse boundary. The facilities manager proposes omitting diesel from the EnMS because the generator seldom runs. How should diesel be handled?

Accepted Answer

Include diesel in the energy review and assess significance using the organization's documented criteria.

Answer

Exclude diesel from the EnMS, but retain its purchase records for financial and compliance purposes.

Answer

Include fuel used for monthly testing, but exclude fuel consumed during actual emergency operation.

Answer

Exclude diesel until generator consumption meets the organization's approved threshold for a significant energy use.

Question 7

Daily energy residuals, defined as actual minus weather- and production-adjusted expected kWh, are plotted around zero with control limits of −60 and +60 kWh. The site's monitoring rules flag either a point beyond a limit or eight successive residuals on one side of zero. The latest nine residuals are +14, +22, +11, +28, +19, +26, +17, +24, and +15 kWh. Meter checks are satisfactory. What does this sequence justify?

Accepted Answer

Investigate a sustained upward shift; the pattern does not identify its cause.

Answer

Continue routine monitoring because no individual observation has crossed a control limit.

Answer

Recalculate the baseline from the nine new values to restore a centered residual chart.

Answer

Attribute the shift to sensor drift and replace the meter before reviewing operating conditions.

Question 8

An independent consultant is commissioned by a retailer to audit the retailer's EnMS against ISO 50001 and the retailer's own procedures. The report is addressed to the retailer's management for internal assurance, not to a certification body for a certification decision. Classify this audit.

Accepted Answer

A first-party management-system audit.

Answer

A second-party supplier audit.

Answer

A third-party management-system certification audit.

Answer

A technical energy-efficiency audit.

Question 9

Two replacement chillers meet the same cooling duty at each operating condition. Chiller A costs $60,000 installed and draws 80 kW at full load or 20 kW at the specified part load. Chiller B costs $52,000 and draws 70 kW or 25 kW, respectively. The planned duty is 500 full-load hours and 3,500 part-load hours annually for five years. Electricity costs $0.20/kWh, with no demand charge. All other energy use and costs are equal; ignore discounting and residual value. Under the five-year ownership-cost criterion, which bid wins and by how much?

Accepted Answer

Chiller A, by $4,500.

Answer

Chiller B, by $8,000.

Answer

Chiller A, by $12,500.

Answer

Chiller B, by $48,000.

Question 10

During management review, top management examines complete performance, audit, and compliance information. A normalized energy-reduction target of 8% has reached only 6% for two consecutive reporting periods. The cause is understood, but the minutes merely state 'report accepted' and record no response to the shortfall. What decision is missing from the review output?

Accepted Answer

What actions and resources are needed to address the missed energy target.

Answer

Whether the certification auditor will approve a revision to the organization's action plan.

Answer

Whether the target should be reduced to 6% solely to match the result already achieved.

Answer

Whether the shortfall can be disregarded because some energy-performance improvement occurred.
