Certified Energy Auditor Audit Strategy and Planning Questions and Answers

Question 1

An energy auditor is hired by a facility manager whose only instruction is to "find ways to reduce our high energy costs." What is the most critical first step the auditor must take to develop an effective audit strategy?

Accepted Answer

Work with the facility manager to formally define the specific audit scope, objectives, and boundaries.

Answer

Before any detailed analysis or on-site work can begin, the auditor and client must agree on the audit's scope and objectives. This ensures both parties have the same expectations regarding the audit's depth (e.g., ASHRAE Level 1, 2, or 3), physical boundaries (e.g., specific buildings or processes), and goals (e.g., cost reduction, carbon footprint reduction, etc.). This step guides all subsequent activities, including data requests and site visit planning. [14]

Question 2

Which of the following activities is a key differentiator of an ASHRAE Level 2 energy audit compared to a Level 1 audit?

Accepted Answer

A detailed breakdown of energy use by specific end-use systems (e.g., lighting, HVAC, process loads).

Answer

While a Level 1 audit includes a walk-through, utility bill review, and benchmarking, a Level 2 audit goes deeper. [21, 13] Its defining characteristic is a more detailed analysis to provide a breakdown of energy consumption by end-use, allowing for more accurate calculations of savings for specific Energy Conservation Measures (ECMs). [17] A Level 3 audit would take this even further with dynamic simulation modeling. [21]

Question 3

During the Preliminary Energy-Use Analysis (PEA) phase of an audit, what is the primary goal for the auditor?

Accepted Answer

To benchmark the facility's performance and identify the largest energy-consuming systems to focus the audit.

Answer

The Preliminary Energy-Use Analysis (PEA) involves analyzing high-level data, like utility bills and building size, to calculate the Energy Use Intensity (EUI) and benchmark it against similar facilities. [2, 4, 5] This initial step helps the auditor identify if the building is a high consumer and points towards the major areas of energy use (e.g., electricity for cooling, natural gas for heating), thereby focusing the subsequent, more detailed investigation. [8]

Question 4

An energy auditor is preparing for an on-site visit to a large, complex manufacturing plant. To ensure the visit is as efficient and productive as possible, which set of documents is most critical to obtain and review beforehand?

Accepted Answer

Architectural drawings, major equipment lists with specifications, and production schedules.

Answer

Reviewing building plans, equipment lists, and operating/production schedules before the visit is crucial for effective planning. [10, 14] This information allows the auditor to understand the facility's layout, identify key energy-consuming systems, and plan the on-site data collection and measurement strategy to align with the plant's operational patterns, maximizing the effectiveness of the time spent on-site.

Question 5

Which of the following best describes the primary purpose of creating a formal energy audit plan before beginning the main fieldwork?

Accepted Answer

To provide a structured roadmap detailing the audit's scope, timeline, tasks, and required resources.

Answer

The audit plan is a project management tool. It outlines the agreed-upon scope, objectives, timeline, team responsibilities, data requirements, and specific tasks to be performed. [24] This ensures the audit is conducted efficiently, thoroughly, and in alignment with the client's expectations, serving as a clear guide for the entire audit team. [25]
