1. What is the primary purpose of a HERS rating?
A. To determine property taxes
B. To evaluate indoor air quality only
C. To measure a home’s energy efficiency performance
D. To certify electrical system safety
Answer: C
Rationale: A HERS rating (Home Energy Rating System) is
designed to evaluate and compare a home's energy efficiency
using standardized procedures, not taxation, air quality alone, or
electrical safety.
2. Which organization oversees the HERS Index standard in the
United States?
A. EPA
, B. RESNET
C. DOE
D. ASHRAE
Answer: B
Rationale: RESNET (Residential Energy Services Network) is the
governing body that establishes and maintains the HERS Index
and certification standards.
3. A lower HERS Index score indicates:
A. Higher energy use
B. Greater energy efficiency
C. Poor insulation
D. Higher carbon emissions
Answer: B
Rationale: On the HERS Index, lower scores represent better
energy efficiency, with 0 being net-zero energy performance.
4. What does a HERS Index score of 100 represent?
A. Net-zero energy home
B. Average new home built to code
C. Historic home efficiency baseline
, D. Passive house standard
Answer: B
Rationale: A score of 100 represents the energy use of a standard
new home built to current energy codes.
5. A HERS Index score of 0 indicates:
A. No insulation in the home
B. Net-zero energy use
C. Average energy consumption
D. Failed certification
Answer: B
Rationale: A score of 0 indicates a net-zero energy home that
produces as much energy as it consumes.
6. Which tool is primarily used to measure air leakage in a home?
A. Infrared thermometer
B. Blower door
C. Psychrometer
D. Manometer
Answer: B
, Rationale: A blower door test depressurizes a home to measure
air infiltration rates.
7. Duct leakage testing primarily evaluates:
A. Electrical safety in ducts
B. Air tightness of HVAC ductwork
C. Water intrusion in ducts
D. Combustion efficiency
Answer: B
Rationale: Duct leakage testing measures how much conditioned
air escapes from duct systems.
8. Which material typically provides the highest R-value per inch?
A. Fiberglass batt
B. Cellulose
C. Spray foam insulation
D. Brick
Answer: C
Rationale: Spray foam insulation generally provides the highest
thermal resistance per inch due to its air-sealing properties.
