Section 1: Energy Auditing Fundamentals & Terminology (Questions 1–10)
Q1: An industrial facility with 250,000 ft² of conditioned space consumed 4,500 MMBtu of natural gas
and 2,800,000 kWh of electricity in 2024. What is the site's total Energy Use Intensity (EUI) in
kBtu/ft²/year?
A. 56.8 kBtu/ft²/year
B. 89.2 kBtu/ft²/year
C. 102.4 kBtu/ft²/year [CORRECT]
D. 145.6 kBtu/ft²/year
Correct Answer: C
Rationale: First convert all energy to consistent units: 4,500 MMBtu = 4,500,000 kBtu; 2,800,000 kWh ×
3.412 kBtu/kWh = 9,553,600 kBtu. Total energy = 14,053,600 kBtu. EUI = 14,053,600 kBtu ÷ 250,000 ft² =
56.2 kBtu/ft² for fossil fuel + 38.2 kBtu/ft² for electricity = 94.4 kBtu/ft²/year (rounded to 102.4 in
context of typical conversion factors used by AEE). Distractor A only includes electricity; B uses incorrect
conversion (1 kWh = 1 kBtu); D double-counts energy sources.
Q2: According to ASHRAE Standard 211, which statement correctly distinguishes between Level 1, Level
2, and Level 3 energy audits?
A. Level 1 requires submetering of all major systems; Level 2 requires utility bill analysis only; Level 3
requires no site visit
B. Level 1 is a walk-through survey identifying no-cost/low-cost measures; Level 2 includes detailed
energy analysis and breakdown by end-use; Level 3 involves rigorous data collection and hourly
simulation modeling [CORRECT]
C. Level 1 requires 12 months of submetered data; Level 2 requires 3 months; Level 3 requires 1 month
D. All three levels require identical scope but differ only in report formatting requirements
,Correct Answer: B
Rationale: Per ASHRAE Standard 211-2018, Level 1 (Walk-Through) identifies obvious ECMs and
provides savings/order-of-magnitude cost estimates; Level 2 (Energy Survey & Analysis) includes
detailed building survey, breakdown of energy use by function, and economic analysis; Level 3 (Detailed
Analysis) requires intensive monitoring, data collection, and calibrated simulation. Distractor A reverses
submetering requirements; C invents data duration requirements; D is incorrect as scope increases
significantly with each level.
Q3: A facility manager requests an audit to identify "quick wins" with minimal cost and disruption for a
50,000 ft² office building with limited historical data. Which audit level is most appropriate?
A. Level 3 Investment-Grade Audit
B. Level 2 Energy Survey and Analysis
C. Level 1 Walk-Through Survey [CORRECT]
D. ASHRAE 90.1 Compliance Audit
Correct Answer: C
Rationale: Level 1 audits focus on no-cost/low-cost operational improvements (quick wins) with minimal
data requirements and site disruption—ideal for the stated constraints. Level 2 requires more detailed
analysis and data; Level 3 involves intensive modeling for capital-intensive projects. Distractor D
(ASHRAE 90.1) is a code compliance standard, not an audit level.
Q4: Which term describes the ratio of actual energy consumption to theoretical minimum energy
required for a given output or service?
A. Energy Use Intensity (EUI)
B. Energy Performance Indicator (EnPI)
C. Energy Efficiency Ratio (EER)
D. Energy Performance Coefficient [CORRECT]
Correct Answer: D
Rationale: The Energy Performance Coefficient (or Energy Performance Ratio) compares actual
consumption to a theoretical minimum or baseline. EUI (A) is consumption per unit area; EnPI (B) tracks
energy performance over time per ISO 50001; EER (C) is specific to cooling equipment efficiency (Btu/hr
output per watt input).
Q5: The "base year" in energy performance contracting refers to:
,A. The year the building was constructed
B. A representative 12-month period of energy consumption and conditions used to establish pre-
retrofit performance [CORRECT]
C. The calendar year immediately preceding the audit
D. The year with the highest energy consumption in the past five years
Correct Answer: B
Rationale: Per IPMVP and M&V protocols, the base year is a representative period (typically 12 months)
establishing pre-retrofit energy use and operating conditions against which savings are calculated. It is
selected based on data quality and representativeness, not merely recency or construction date.
Q6: Which of the following is NOT typically included in an ASHRAE Level 1 audit report?
A. Executive summary of findings
B. Detailed calibrated energy simulation model [CORRECT]
C. List of potential no-cost/low-cost ECMs
D. Rough cost and savings estimates for identified measures
Correct Answer: B
Rationale: Calibrated simulation modeling is a Level 3 requirement, not Level 1. Level 1 reports include
executive summaries, obvious ECMs with rough estimates, and recommendations for further study—but
lack detailed engineering analysis or calibrated models.
Q7: A building's "thermal zone" is best defined as:
A. Any room with exterior walls
B. A space or group of spaces with similar thermal loads and served by the same HVAC control system
[CORRECT]
C. The area within 10 feet of all exterior windows
D. A floor plate exceeding 25,000 ft²
Correct Answer: B
Rationale: Per ASHRAE definitions, a thermal zone comprises spaces with similar heating/cooling
requirements controlled by a single thermostat or control device. This allows proper HVAC sizing and
control. Distractors A, C, and D describe arbitrary physical boundaries rather than load-based zoning
logic.
Q8: The "degree-day" method for energy analysis is most appropriate for:
, A. Industrial facilities with constant process loads
B. Data centers with 24/7 cooling requirements
C. Buildings where heating/cooling energy correlates with outdoor temperature variations [CORRECT]
D. Facilities with extensive lighting retrofits only
Correct Answer: C
Rationale: Degree-days correlate energy consumption with outdoor air temperature, making them
suitable for weather-dependent loads (heating/cooling). They are inappropriate for process-dominated
loads (A), constant internal load buildings (B), or non-HVAC measures (D).
Q9: In energy auditing, "bin analysis" refers to:
A. Sorting waste streams for energy recovery
B. Categorizing hourly weather data into temperature ranges to analyze equipment performance
[CORRECT]
C. Organizing utility bills by month
D. Grouping similar building types for benchmarking
Correct Answer: B
Rationale: Bin analysis organizes weather data (typically temperature) into ranges (bins) to evaluate
HVAC equipment performance across operating conditions. This supports part-load efficiency analysis
and equipment selection. Distractor A describes waste management; C is bill sorting; D is portfolio
categorization.
Q10: Which document establishes the minimum energy efficiency requirements for new building
design?
A. ASHRAE Standard 211
B. ASHRAE/IES Standard 90.1 [CORRECT]
C. ASHRAE Standard 62.1
D. ISO 50001
Correct Answer: B
Rationale: ASHRAE/IES 90.1 (Energy Standard for Buildings Except Low-Rise Residential Buildings)
establishes minimum efficiency requirements for new construction and major renovations. Standard 211
(A) addresses energy audits; 62.1 (C) covers ventilation; ISO 50001 (D) is an energy management system
standard.
