Building Science / Construction Trade
BPI BA‑P Exam: - Covers building science (heat transfer, psychrometrics,
moisture), combustion safety (CAZ depressurization, CO limits, draft
testing), blower door diagnostics (ACH50, natural infiltration), ASHRAE
62.2 ventilation, duct leakage testing, HVAC performance (temperature
rise, static pressure, cooling capacity), energy modeling (bin method,
HERS index, REM/Rate), and work scope prioritization. Ideal for energy
auditors, home performance contractors, weatherization professionals,
and BPI BA‑P candidates. Keywords: BPI BA‑P practice test, building
analyst exam bank, combustion safety questions, blower door test,
ASHRAE 62.2 ventilation
Section 1: Building Science Fundamentals (1–40)
1. A homeowner in a cold climate notice that the upstairs bedrooms are
much warmer than the downstairs living room during winter. The heating
system is a forced air furnace with supply registers in every room. Which
building science principle most directly explains this temperature
difference?
A. Conduction through the exterior walls
B. Stack effect causing warm air to rise
C. Radiant heat from the sun warming the roof
D. Infiltration of cold air through basement cracks
, Page 2 of 73
CORRECT ANSWER: B
Rationale: Stack effect drives warm air upward due to buoyancy, creating
upper-floor overheating even with balanced supply registers.
2. An energy auditor measures the R‑value of an attic insulation layer at
30. If the insulation is compressed from its original 12‑inch thickness to
6 inches, what happens to the effective R‑value?
A. It doubles to 60
B. It remains 30 because R‑value per inch doubles
C. It decreases significantly, possibly by half or more
D. It converts to a reflective barrier value
CORRECT ANSWER: C
Rationale: Compressing fiberglass reduces trapped air pockets, lowering
R‑value roughly in proportion to thickness reduction.
3. During a summer cooling season, a dehumidifier removes 5 pints of
water per hour from the indoor air. This water removal represents which
type of heat load on the house?
A. Sensible heat load
B. Latent heat load
C. Radiant heat load
D. Conductive heat load
CORRECT ANSWER: B
, Page 3 of 73
Rationale: Latent heat is associated with phase change (condensation of
water vapor), not temperature change.
4. A wall assembly consists of exterior siding, plywood sheathing,
fiberglass batt insulation inside the stud cavity, and interior drywall.
Where is the primary thermal boundary located in this assembly?
A. At the exterior siding surface
B. At the plywood sheathing
C. At the plane of the fiberglass insulation
D. At the interior drywall surface
CORRECT ANSWER: C
Rationale: The thermal boundary is the plane where insulation is placed;
it resists heat flow between conditioned and unconditioned space.
5. A metal stud in an exterior wall conducts heat from the interior to the
exterior much faster than the surrounding insulation. What is the correct
term for this phenomenon?
A. Thermal bypass
B. Thermal bridge
C. Thermal mass effect
D. Thermal stratification
CORRECT ANSWER: B
Rationale: A thermal bridge is a highly conductive path through the
building envelope that reduces overall effective R‑value.

6. According to the second law of thermodynamics, if you place a cold
glass of water in a warm room, which direction will heat flow?
A. From the cold water to the warm room air
B. From the warm room air to the cold water
C. Heat will not flow because the system is at equilibrium
D. Heat will flow upward from the glass only
CORRECT ANSWER: B
Rationale: Heat spontaneously flows from higher temperature (warm air)
to lower temperature (cold water).
7. A homeowner touches a metal window frame on a cold winter day and
feels a strong chill, even though the room air temperature is 70°F. Which
type of heat transfer is causing the hand to lose heat to the metal frame?
A. Convection from the hand to the air
B. Conduction from the hand to the metal
C. Radiation from the hand to the window glass
D. Evaporation of moisture on the hand
CORRECT ANSWER: B
Rationale: Direct contact between skin and metal enables conductive
heat transfer away from the hand.
