Introduction
,The BPI certification exam assesses the knowledge and skills required to conduct comprehensive building performance
evaluations. Candidates are tested on building science principles, diagnostic testing procedures, HVAC system
interactions, and compliance with industry standards. The exam employs multiple-choice and scenario-based questions
to evaluate both foundational theory and applied decision-making. Emphasis is placed on real-world application,
including identifying health and safety hazards, prioritizing improvement measures, and making defensible
recommendations that improve occupant comfort, energy efficiency, and building durability.
SECTION ONE: QUESTIONS 1–50
Question 1
Which principle best describes the building-as-a-system approach used in building performance analysis?
A. Each building component should be evaluated independently without considering interactions
B. HVAC equipment is always the primary cause of energy consumption
C. Changes to one building component can affect the performance of other components
D. Envelope improvements should be completed without considering ventilation needs
🟢 Correct Answer: C. Changes to one building component can affect the performance of other components
,🔴 Explanation: Building performance depends on interactions among the enclosure, HVAC systems, pressure
relationships, moisture, ventilation, and occupants. Modifying one element can have unintended consequences
elsewhere in the system.
Question 2
What is the primary purpose of a blower door test?
A. Measure water pressure in plumbing systems
B. Identify and quantify air leakage in a building enclosure
C. Test refrigerant pressure in HVAC equipment
D. Measure electrical resistance in wiring
🟢 Correct Answer: B. Identify and quantify air leakage in a building enclosure
🔴 Explanation: A blower door depressurizes or pressurizes the building to measure leakage and help locate
significant air pathways through the building envelope.
Question 3
, During a blower door depressurization test, what generally happens to the indoor pressure relative to outdoors?
A. It becomes substantially higher than outdoors
B. It remains exactly equal to outdoors
C. It is reduced relative to outdoors
D. It becomes equal to combustion pressure
🟢 Correct Answer: C. It is reduced relative to outdoors
🔴 Explanation: In a typical depressurization test, the blower door exhausts indoor air, creating a negative pressure
relative to outside.
Question 4
What does ACH50 represent in building diagnostics?
A. Air changes per hour at 50% relative humidity
B. Air changes per hour under a 50 Pa test pressure
C. Annual cooling hours at 50 degrees
D. Average combustion heat output
