1. Which code primarily governs commercial energy efficiency
requirements in most U.S. jurisdictions?
A. NFPA 70
B. International Energy Conservation Code (IECC)
C. International Building Code (IBC)
D. International Plumbing Code (IPC)
Answer: B
Rationale: The IECC establishes minimum energy efficiency
requirements for building design and construction.
2. The primary purpose of an energy code is to:
A. Regulate structural safety
B. Reduce water usage
C. Improve energy efficiency in buildings
, D. Control fire hazards
Answer: C
Rationale: Energy codes are designed to reduce energy consumption
in buildings.
3. Which building component has the greatest impact on heating and
cooling loads?
A. Roof assembly
B. Electrical system
C. Interior finishes
D. Furniture layout
Answer: A
Rationale: The roof is a major contributor to heat gain and loss due to
exposure.
4. U-factor measures:
A. Air leakage
B. Heat transfer rate
C. Solar gain
D. Lighting efficiency
Answer: B
Rationale: U-factor represents the rate of heat transfer through a
building assembly.
,5. R-value represents:
A. Resistance to heat flow
B. Air infiltration rate
C. Solar heat gain
D. Electrical resistance
Answer: A
Rationale: Higher R-values indicate better insulation performance.
6. Which system is typically regulated by the energy code?
A. Fire sprinkler systems
B. HVAC systems
C. Plumbing venting
D. Structural framing
Answer: B
Rationale: HVAC systems are major energy consumers and regulated
for efficiency.
7. Which is a prescriptive compliance path?
A. Energy modeling
B. Performance simulation
C. Trade-off method
D. Meeting listed code values for each component
Answer: D
, Rationale: Prescriptive compliance requires meeting specific
component requirements.
8. Air leakage in buildings is commonly measured in:
A. Watts
B. ACH50
C. BTU/hr
D. Lumens
Answer: B
Rationale: ACH50 measures air changes per hour at 50 Pascals
pressure.
9. The primary purpose of a thermal envelope is to:
A. Support structural loads
B. Separate conditioned and unconditioned spaces
C. Provide fire resistance
D. Improve acoustics only
Answer: B
Rationale: The thermal envelope reduces heat transfer between
interior and exterior.
10. Which is considered part of the building envelope?
A. Air conditioner
B. Exterior walls
C. Water heater
