Certified Energy Auditor Certification Audit Strategy and Planning 3 — Questions and Answers
Question 1: During audit planning, an auditor discovers that a manufacturing plant operates three shifts per day. How does this affect the audit strategy?
- Shift schedules are irrelevant to energy audits
- The auditor should schedule site visits across all shifts to capture load variations (Correct answer)
- Only the day shift needs to be audited
- The audit scope should be reduced to save time
Correct answer: The auditor should schedule site visits across all shifts to capture load variations
Multi-shift operations create different energy load profiles per shift, so visiting during multiple shifts ensures the auditor captures all significant consumption patterns.
Question 2: Which of the following best describes the concept of an energy baseline in audit planning?
- The minimum energy the facility must use to comply with codes
- A historical reference period of energy use against which future savings are measured (Correct answer)
- The rated energy consumption from equipment nameplates
- The energy budget approved for the next fiscal year
Correct answer: A historical reference period of energy use against which future savings are measured
An energy baseline represents actual historical consumption, typically 12–36 months of utility data, used as the reference point for calculating post-ECM savings.
Question 3: What is the purpose of creating an energy balance (or energy model) during audit planning?
- To satisfy OSHA safety requirements
- To reconcile measured energy inputs with end-use consumption and identify discrepancies (Correct answer)
- To calculate utility rate structures
- To document the audit fee schedule
Correct answer: To reconcile measured energy inputs with end-use consumption and identify discrepancies
An energy balance ensures total metered energy equals the sum of all end uses, helping auditors spot unaccounted losses or metering errors.
Question 4: An auditor is asked to prioritize ECMs for a client with limited capital. Which financial metric best supports a payback-focused decision?
- Net present value (NPV)
- Simple payback period (SPP) (Correct answer)
- Internal rate of return (IRR)
- Life-cycle cost (LCC)
Correct answer: Simple payback period (SPP)
Simple payback period (SPP) divides implementation cost by annual savings and is the most straightforward metric for clients focused on recovering their investment quickly.
Question 5: Which team member is most critical to interview during the planning phase of an industrial facility audit?
- Receptionist
- Plant engineer or energy manager (Correct answer)
- Chief financial officer
- IT department head
Correct answer: Plant engineer or energy manager
The plant engineer or energy manager has direct knowledge of operational schedules, equipment performance, past energy projects, and known inefficiencies critical to audit planning.
Question 6: When planning an audit for a facility with submeters, what is the primary advantage of using submeter data?
- Submeters eliminate the need for utility bills
- Submeters allow end-use disaggregation, pinpointing which systems consume the most energy (Correct answer)
- Submeters automatically identify ECMs
- Submeters reduce the audit fee
Correct answer: Submeters allow end-use disaggregation, pinpointing which systems consume the most energy
Submeter data breaks total consumption into individual system-level loads (HVAC, lighting, process), enabling auditors to focus efforts on the highest-impact areas.
Question 7: A retail chain requests audits at 50 locations. Which planning approach maximizes efficiency?
- Conduct a unique custom audit at each location
- Develop a standardized audit protocol with a common data collection template (Correct answer)
- Audit only the largest locations
- Hire 50 independent auditors without coordination
Correct answer: Develop a standardized audit protocol with a common data collection template
A standardized audit protocol ensures consistent data collection across all sites, enables benchmarking between locations, and reduces overall audit time and cost.
