Question 1. In Virginia, what is the minimum number of supervised
residential building energy analyses an applicant must complete
before licensure as a Residential Building Energy Analyst?
A. Two
B. Three
C. Five
D. Ten
Correct Answer: C. Five
Rationale: Virginia regulations require applicants to complete at least
five residential building energy analyses under the supervision of a
licensed Residential Building Energy Analyst before obtaining licensure.
Question 2. What is the primary mechanism by which water vapor
moves through a solid building material?
A. Air convection
B. Capillary action
C. Vapor diffusion
D. Gravity
Correct Answer: C. Vapor diffusion
,Rationale: Vapor diffusion is the process by which water vapor moves
through a material from an area of high vapor pressure to an area of
low vapor pressure. This occurs at a molecular level through the
material itself.
Question 3. A house has a conditioned volume of 12,000 ft³ and a
blower door reading of 3,000 CFM at 50 Pa. What is the ACH50?
A. 5.0
B. 10.0
C. 15.0
D. 20.0
Correct Answer: C. 15.0
Rationale: ACH50 = (CFM50 × 60) ÷ Volume = (3,000 × 60) ÷ 12,000 =
180,000 ÷ 12,000 = 15.0 air changes per hour at 50 Pa.
Question 4. In a heating-dominated climate, what is the primary
driving force for air movement through a building envelope?
A. Wind pressure
B. The stack effect
C. Mechanical ventilation
D. Diffusion
Correct Answer: B. The stack effect
Rationale: The stack effect is caused by the difference in temperature
and density between indoor and outdoor air. Warm, buoyant indoor air
,rises and escapes through upper leaks, drawing in cold outdoor air at
lower levels.
Question 5. Which combustion appliance component generates
enough voltage to supply power to the combustion safety circuit as
well as the gas valve?
A. Thermocouple
B. Thermopile
C. Flame sensor
D. Spark igniter
Correct Answer: B. Thermopile
Rationale: A thermopile generates enough voltage to supply power to
the combustion safety circuit as well as the gas valve. A thermocouple
only generates enough voltage to hold open a pilot safety valve.
Question 6. What is the maximum flame failure response time (FFRT)
for an appliance with an input greater than 120 kW?
A. 1 second
B. 2 seconds
C. 4 seconds
D. 10 seconds
Correct Answer: C. 4 seconds
Rationale: For appliances with an input greater than 120 kW, the
maximum Flame Failure Response Time is 4 seconds, according to
ANSI/BPI-1200 standards.
, Question 7. In weather normalization of energy data, an auditor
adjusts energy consumption based on which metric?
A. Occupancy schedules
B. Lighting upgrades
C. Heating and cooling degree days
D. Fuel price changes
Correct Answer: C. Heating and cooling degree days
Rationale: Degree days account for deviations in weather relative to a
baseline, isolating weather impacts from other factors affecting energy
consumption.
Question 8. What is the primary purpose of a zonal pressure
diagnostic test?
A. Measure building airtightness
B. Quantify air leakage from the house to intermediate zones
C. Measure combustion efficiency
D. Measure insulation R-value
Correct Answer: B. Quantify air leakage from the house to
intermediate zones
Rationale: Zonal pressure diagnostics help quantify air leakage from the
house to intermediate zones such as attics and crawl spaces by using
pressure measurements to assess connection tightness.
