General Questions

Q1: What is the BPI BAT Exam, and who should take it?
The BPI Building Analyst Technician (BAT) Exam certifies professionals in energy auditing and building performance. It’s ideal for individuals who inspect residential homes, analyze energy efficiency, and ensure safety in combustion appliances and building systems.

Q2: How is the BAT exam structured?BAT Exam:

1. Field Exam Only, no written exam: Evaluates hands-on skills, such as conducting blower door tests, measuring CO levels, and inspecting HVAC systems.

2. BAP Exam:

Written Exam Only, no Field Exam: Tests theoretical knowledge of building science, safety standards, and diagnostic methods.

Preparation

Q3: What study materials should I use to prepare for the BAT exam?
Key resources include:

• ANSI/BPI-1200 Standards document.

• Building Analyst Technician Field Guide.

• Reference Tables for diagnostic limits and technical specifications.

• Practice quizzes and field exercises.

Q4: Are there any prerequisites for taking the BAT exam?
Yes, the Building Science Principles certificate is the prerequisite for the Building Analyst-Tech certification exam. Also the Building Analyst-Tech is the prerequisite for the Building Analyst-Pro certification exam. Step 1 BSP, Step 2 BAT, Step 3 BAP.

Exam Logistics

Q5: How do I register for the BAT exam?
You can register through BPI authorized test centers like EnergyScore. Upon registration you will click a calendar link and schedule your remote certification exam. 

Q6: How long is the BAT exam?

• BAT Field Exam: Approximately 2-4 hours, depending on the complexity of tasks assigned 

• BAP Written Exam: Typically 2-3 hours.

During the Exam

Q7: What equipment will I need for the field exam?
You may need access to:

• Blower door test kit.

• Manometer.

• Combustible gas detector (CGD).

• CO monitor.

• Thermometer and measuring tape.

Q8: What are common mistakes to avoid during the field exam?

• Forgetting to zero out diagnostic tools.

• Skipping safety steps, such as monitoring ambient CO levels.

• Failing to communicate findings clearly to the proctor.

• Skipping items on the BAT field guide
  

Key Topics

Q9: What are the most important topics covered on the BAT exam?

• Combustion safety (spillage, CO testing, depressurization).

• Blower door testing and air leakage.

• Insulation and building envelope performance.

• Indoor air quality and ventilation.

• HVAC systems and appliance inspection.

Q10: How do I measure success in the combustion safety portion?
Ensure:

• You correctly identify and mitigate safety issues (e.g., high CO levels or spillage).

• Tools are properly set up and ready for use.

• All action levels and responses align with ANSI/BPI-1200 standards.

After the Exam

Q11: How is the BAT exam scored?

• Written Exam: Multiple-choice and short-answer questions are graded based on accuracy.

• Field Exam: Proctors evaluate your performance using a checklist of required tasks and safety protocols.

Q12: What happens if I fail one part of the exam?
If you fail one part (written or field), you can retake that section without redoing the other. Check with your testing provider for retake policies and fees.

Q13: How long does certification last, and how do I renew it?
BPI certifications are valid for three years. Renewal typically involves continuing education credits or retaking the exam. Here is a useful article on BPI recertification.
