1. Which code primarily governs commercial building energy
efficiency requirements in most jurisdictions adopting ICC
standards?
A. IBC
B. IECC
C. IMC
D. IFC
Answer: B
Rationale: The International Energy Conservation Code (IECC)
sets minimum energy efficiency requirements for commercial
and residential buildings.
2. What is the primary purpose of building envelope requirements in
energy codes?
A. Structural safety
B. Fire resistance
C. Thermal efficiency
, D. Plumbing efficiency
Answer: C
Rationale: Building envelope requirements reduce heat transfer
between interior and exterior spaces.
3. Which component is NOT part of the building thermal envelope?
A. Roof
B. Exterior walls
C. Interior partitions
D. Floors over unconditioned space
Answer: C
Rationale: Interior partitions are not part of the thermal
envelope since they do not separate conditioned and
unconditioned spaces.
4. U-factor measures:
A. Air leakage
B. Heat transfer rate
C. Solar gain
D. Moisture resistance
Answer: B
Rationale: U-factor quantifies the rate of heat transfer through a
building assembly.
5. R-value represents:
A. Air infiltration
B. Thermal resistance
C. Heat capacity
, D. Solar reflectance
Answer: B
Rationale: R-value measures resistance to heat flow; higher
values indicate better insulation.
6. Which system is most commonly regulated for energy efficiency in
commercial buildings?
A. Fire alarm system
B. HVAC system
C. Elevator system
D. Security system
Answer: B
Rationale: HVAC systems consume the most energy and are
heavily regulated under energy codes.
7. What does economizer operation primarily provide?
A. Heating efficiency
B. Free cooling using outdoor air
C. Humidity control only
D. Refrigerant recovery
Answer: B
Rationale: Economizers use cool outdoor air to reduce
mechanical cooling demand.
8. Lighting power density is measured in:
A. Watts per cubic foot
B. Watts per square foot
C. Lumens per watt
, D. BTU per hour
Answer: B
Rationale: Lighting power density (LPD) is expressed in watts per
square foot.
9. Which system improves HVAC efficiency by recovering energy
from exhaust air?
A. Variable refrigerant flow
B. Energy recovery ventilation
C. Split system cooling
D. Heat pump bypass
Answer: B
Rationale: Energy recovery ventilation transfers energy between
exhaust and incoming air streams.
10. The purpose of air barriers is to:
A. Prevent fire spread
B. Control air leakage
C. Increase ventilation
D. Reduce sound transmission
Answer: B
Rationale: Air barriers limit uncontrolled air movement through
the building envelope.
11. Which test is commonly used to measure building air
leakage?
A. Duct leakage test
B. Blower door test
