Certified Energy Auditor Certification Energy Audit Process 2

Question 1

Which document is most critical to review during the pre-audit phase to understand a building's energy consumption history?

Accepted Answer

Utility billing records for 12–24 months

Answer

Utility billing records spanning 12–24 months establish the baseline energy use intensity (EUI) and reveal seasonal consumption patterns essential for audit planning.

Question 2

During a walk-through audit, an auditor notices condensation on interior window surfaces in winter. What does this primarily indicate?

Accepted Answer

High indoor humidity combined with poor window insulation value

Answer

Condensation on interior glazing occurs when warm, humid indoor air contacts a cold surface, signaling low window U-value and potentially high relative humidity.

Question 3

What is the primary purpose of a blower door test in an energy audit?

Accepted Answer

Quantify building envelope air leakage

Answer

A blower door depressurizes the building to a standard pressure (typically 50 Pa) and measures the airflow required, revealing total envelope air leakage in CFM50 or ACH50.

Question 4

An energy auditor calculates a simple payback period of 6 years for a lighting retrofit costing $18,000. What annual energy savings does this imply?

Accepted Answer

$3,000

Answer

Simple payback = Cost ÷ Annual Savings; $18,000 ÷ 6 years = $3,000 per year in energy savings.

Question 5

Which ASHRAE audit level involves detailed energy modeling and investment-grade analysis?

Accepted Answer

Level III – Detailed Analysis

Answer

ASHRAE Level III audits provide rigorous engineering analysis with calibrated simulation models, suitable for major capital investment decisions.
