BPI HEP Energy Auditor Certification Exam – Practice
Questions & Verified Answers 2026 Pennsylvania College
The BPI Home Energy Professional (HEP) Energy Auditor certification is a rigorous,
advanced credential supported by the U.S. Department of Energy that qualifies
professionals to conduct comprehensive home energy audits, including advanced
diagnostic testing with blower doors and combustion analyzers. To earn this
certification, candidates must meet strict prerequisites, which include 1,000 hours
of relevant field experience and completion of 10 energy models or specialized
training, then pass a 100-question online exam (75% passing score) and a 4-hour
field exam with mandatory safety "gated" tasks. Once certified, professionals can
evaluate a home's health, safety, and efficiency, produce detailed audit reports,
and leverage the credential for DOE-recognized programs and energy tax credits
Blower door results are typically reported in:
A. PSI
B. CFM50
C. BTU/hr
D. ACHnat
Answer: B
Rationale: CFM50 is airflow at 50 Pascals.
What does ACH50 represent?
,A. Annual air changes
B. Air changes per hour at 50 Pascals
C. Natural ventilation rate
D. Duct leakage rate
Answer: B
Rationale: ACH50 normalizes leakage by building volume.
. The stack effect is driven primarily by:
A. Wind
B. Mechanical ventilation
C. Temperature difference
D. Barometric pressure
Answer: C
Rationale: Warm air rises, creating pressure differences.
1. The primary goal of a BPI Energy Auditor is to:
A. Increase home value
B. Reduce energy bills only
C. Improve energy efficiency while maintaining occupant health and safety
D. Replace HVAC systems
Answer: C
Rationale: BPI prioritizes energy efficiency and health/safety together.
,2. The “house as a system” concept means:
A. Each component works independently
B. Changes to one system affect others
C. Only HVAC impacts efficiency
D. Envelope upgrades don’t affect IAQ
Answer: B
Rationale: All building components interact.
3. Which pressure boundary separates conditioned space from unconditioned
space?
A. Thermal boundary
B. Air barrier
C. Vapor retarder
D. Drainage plane
Answer: B
Rationale: The air barrier controls air movement and pressure.
4. A blower door test measures:
A. Insulation R-value
B. Air leakage of the building
C. Duct leakage only
, D. Combustion efficiency
Answer: B
Rationale: Blower doors quantify whole-house air leakage.
5.
8. Which season typically produces the strongest stack effect in cold climates?
A. Summer
B. Spring
C. Fall
D. Winter
Answer: D
Rationale: Greater indoor-outdoor temperature differences increase stack effect.
9. Duct leakage testing is commonly performed using a:
A. Blower door only
B. Duct blaster
C. Smoke pencil only
D. Combustion analyzer
Answer: B
