COMPLETE EXAM Q&A WITH RATIONALES
1. A room in a home is measured at 72 square feet,
has an egress window, and has a doorway to the
main living area. According to RESNET standards, is
this room considered a bedroom?
A) No, because it lacks a closet
B) Yes, because it meets the minimum square footage
requirement of 70 square feet
C) No, because the ceiling height is less than 7 feet
D) Yes, if it has a second means of egress
Correct answer: B
Rationale: RESNET standards define a bedroom as a
room with at least 70 square feet of floor area, an
egress window or skylight, and a doorway to the main
body of the dwelling unit. A closet is not required.
2. Which of the following is NOT considered a
minimum rated feature that a rater must inspect
during a HERS rating?
A) Foundation
,B) Walls
C) Interior paint color
D) Windows
Correct answer: C
Rationale: The minimum rated features are
foundation, walls, roof/ceiling, rim joist, doors,
windows, skylights, air leakage, heating and cooling,
hot water heating, solar water system, and passive
solar system. Interior paint color does not affect
energy performance.
3. A home has a HERS Index of 85. Compared to the
reference home, this home is:
A) 15% less energy efficient
B) 15% more energy efficient
C) 85% more energy efficient
D) 85% less energy efficient
Correct answer: B
Rationale: Each 1-point decrease in the HERS Index
represents a 1% reduction in energy use compared to
the reference home. A HERS Index of 85 means the
home is 15% more efficient than the reference home
(100 – 85 = 15).
,4. A rater discovers that a home's ductwork is
located entirely within the conditioned space
envelope. According to RESNET standards, what is
the default duct leakage value that can be used?
A) 10% of fan flow
B) Zero
C) 5% of fan flow
D) 2% of fan flow
Correct answer: B
Rationale: For duct systems located entirely within
the dwelling unit's tested pressure boundary during
the blower door test, the duct leakage may be
modeled as zero.
5. What is the purpose of the RESNET Code of Ethics?
A) To set building code requirements
B) To establish principles and rules of conduct
enforced by RESNET
C) To define energy modeling software accreditation
D) To determine HERS Index calculation methods
Correct answer: B
Rationale: The Code of Ethics sets forth principles
and rules of conduct enforced by RESNET through
, specific procedures contained in its Accreditation
Standards.
6. When conducting a HERS rating, the rated home
and the corresponding reference home will always
have the same:
A) Window orientation
B) Insulation levels
C) Site location
D) HVAC efficiency
Correct answer: C
Rationale: The reference home is modeled with the
same site location (climate) as the rated home to
ensure accurate comparison of energy performance.
7. According to RESNET standards, a home with a
HERS Index of 0 produces:
A) No energy
B) As much energy annually as it uses
C) Twice as much energy as it uses
D) Half as much energy as it uses
Correct answer: B
