1. Which code primarily governs residential energy efficiency
requirements in most U.S. jurisdictions?
A) IBC
B) IECC
C) IFC
D) IMC
Correct answer: B
Rationale: The International Energy Conservation Code (IECC)
establishes minimum energy efficiency requirements for residential
buildings.
2. The primary purpose of the IECC is to:
A) Regulate structural safety
, B) Establish fire protection standards
C) Reduce energy consumption in buildings
D) Control plumbing installations
Correct answer: C
Rationale: The IECC is designed to improve energy efficiency and
reduce overall energy use in buildings.
3. Which compliance approach is MOST commonly used for residential
energy code compliance?
A) Performance path
B) Prescriptive path
C) Energy rating index only
D) Administrative path
Correct answer: B
Rationale: The prescriptive path is the most straightforward and
commonly used method for residential compliance.
4. U-factor measures:
A) Air leakage
B) Heat transfer rate through assemblies
C) Solar gain
D) Moisture diffusion
Correct answer: B
, Rationale: U-factor measures how well a building assembly conducts
heat; lower values mean better insulation.
5. R-value represents:
A) Air infiltration resistance
B) Thermal resistance
C) Solar reflectance
D) Mechanical efficiency
Correct answer: B
Rationale: R-value indicates resistance to heat flow; higher values
mean better insulation.
6. SHGC stands for:
A) Solar Heat Gain Coefficient
B) Structural Heat Gain Control
C) Solar Humidity Gas Control
D) Seasonal Heating Grade Calculation
Correct answer: A
Rationale: SHGC measures how much solar radiation passes through
glazing.
7. The LOWER the SHGC, the:
A) More heat enters the building
B) Less solar heat is transmitted
C) Higher the air leakage
, D) Lower the insulation value
Correct answer: B
Rationale: Lower SHGC means less solar heat gain through windows.
8. Which climate factor MOST affects envelope insulation requirements?
A) Wind direction
B) Climate zone
C) Building occupancy
D) Roof color
Correct answer: B
Rationale: Energy code insulation requirements are based on climate
zones.
9. Which tool is commonly used for REScheck compliance?
A) Structural analysis software
B) Energy compliance software
C) Plumbing calculator
D) Fire modeling software
Correct answer: B
Rationale: REScheck is used to demonstrate energy code compliance.
10. Which is NOT part of the building thermal envelope?
A) Walls
B) Roof
C) Foundation
