Test Centers: Updates for Building Analyst and Envelope Professional
Building science and energy auditing practices are continuously evolving. There is a regular flow of new technology and techniques as well as new career ladders for those in the home performance industry, so all BPI certifications are periodically updated.
BPI’s Building Analyst (BA) and Envelope Professional (EP) certifications have been a staple in the industry for over 20 years. In 2020, we convened a Scheme Committee comprised of Subject Matter Experts (SMEs) to evaluate the BA and EP against the current state of industry.
This open and transparent process, which took about 18 months to complete, ensures that BPI Certified Professionals have expertise in the latest best practices. The resulting updates will lead to increased confidence from customers, contractors, participating programs, and the home performance market at large.
Summary of Changes
Three major changes resulted from the recommendations by the Scheme Committee:
1. The Building Analyst certification has absorbed the Envelope Professional and been divided into two work-ready credentials, Building Analyst Technician (BA-T) and Building Analyst Professional (BA-P).
2. The BA-T covers data collection and diagnostic testing. It is awarded by passing a field exam that includes oral questions. The Building Science Principles certificate is a prerequisite for the BA-T exam.
3. The BA-P covers the principles of using computer software to model the energy upgrade potential of a home and developing a scope of work. The BA-P is awarded by passing a written exam. The BA-T is a prerequisite for the BA-P.
The exams for the updated certifications will be available at BPI Test Centers on January 1st, 2023.
Why Were These Changes Created?
BPI assembled a team of Subject Matter Experts to update the JTA for the BA. Through their analysis, the team determined that breaking the updated Building Analyst JTA into two stepped certifications, Building Analyst Technician (BA-T) and Building Analyst Professional (BA-P), would be beneficial to the industry.
Many practitioners currently work within data collection and diagnostic testing but do no energy modeling or scopes of work. The BA-T aligns with this practice: A Building Analyst Technician conducts residential building science-based diagnostic tests and home performance data collection. This certification gives an easier entrance to the industry while providing a clear path for professional growth.
The BA-P is a progression from the BA-T and is defined as follows: A Building Analyst Professional is a certified Building Analyst Technician who also conducts energy modeling, building analysis, and data evaluation to provide a comprehensive report with a list of prioritized home performance recommendations.
These stepped certifications are better aligned with current industry practices, promote career progression, and will encourage the entry of new professionals into the industry.

Frequently Asked Questions
1. What are the prerequisites for BA-T field exam?
BPI's Building Science Principles Certificate of Knowledge (BSP) is a prerequisite for the BA-T exam. Candidates will provide the certificate to the Test Center when scheduling the exam.
2. What is the BSP and why is it a prerequisite for the BA-T field exam?
The Scheme committee, a group of subject matter experts, determined that the Building Science Principles certificate contains important base knowledge that every home performance professional should understand when entering the trade.
3. How do I obtain my BSP Certificate?
You may purchase the BSP Guide, pay the exam fee, and challenge the exam online from your own home. Visit www.bpi.org/bsp to get started. Some BPI Test Centers provide BSP training and proctor the BSP exam. If you prefer this kind of support, enter your zip code in the Test Center tab of the locator tool to find a Test Center near you.
4. What are the prerequisites for BA-P certification?
You must have an active BA-T certification to challenge the BA-P written exam.
5. Where do I go to take the BA-T and BA-P exams?
BPI’s certification exams are administered at BPI Test Centers around the country. Enter your zip code here and select the Locator tab to find a test center near you. Most Test Centers also provide trainings, so reach out to them directly to learn more about training and to schedule tests.
