1. Which building code primarily governs residential energy efficiency
requirements in Minnesota?
A. International Plumbing Code (IPC)
B. International Mechanical Code (IMC)
C. International Energy Conservation Code (IECC)
D. National Electrical Code (NEC)
C. International Energy Conservation Code (IECC)
The IECC establishes minimum energy efficiency standards for
residential buildings, including insulation, air sealing, and HVAC
efficiency requirements.
2. What is the primary purpose of a blower door test?
A. Measure electrical load
, B. Determine water leakage in plumbing
C. Assess building airtightness
D. Measure HVAC airflow only
C. Assess building airtightness
A blower door test depressurizes a building to measure air leakage
and infiltration rates.
3. Which unit is used to measure thermal resistance?
A. BTU
B. R-value
C. Watt
D. Pascal
B. R-value
R-value measures resistance to heat flow, with higher values
indicating better insulation performance.
4. Heat transfer through direct contact is called:
A. Radiation
B. Convection
C. Conduction
D. Infiltration
C. Conduction
Conduction occurs when heat flows through solid materials due to
molecular contact.
,5. Which material typically has the highest insulating value per inch?
A. Concrete
B. Fiberglass
C. Steel
D. Brick
B. Fiberglass
Fiberglass insulation has a high R-value per inch compared to dense
structural materials.
6. Air leakage in a home primarily affects:
A. Structural strength
B. Energy consumption
C. Plumbing efficiency
D. Electrical grounding
B. Energy consumption
Air leakage increases heating and cooling loads, reducing energy
efficiency.
7. The primary function of a vapor barrier is to:
A. Increase airflow
B. Block moisture diffusion
C. Improve electrical safety
D. Increase solar gain
B. Block moisture diffusion
, Vapor barriers prevent moisture movement into wall assemblies,
reducing condensation risks.
8. Which system is most affected by duct leakage?
A. Plumbing
B. Electrical
C. HVAC
D. Structural framing
C. HVAC
Leaky ducts reduce heating and cooling efficiency by losing
conditioned air.
9. The U-factor measures:
A. Air leakage
B. Heat transfer rate
C. Solar gain
D. Moisture content
B. Heat transfer rate
U-factor indicates how much heat is lost through a material; lower
values are better.
10. Which component reduces thermal bridging?
A. Metal studs
B. Continuous insulation
C. Single-pane glass
D. Bare concrete walls
