Building Science Principles (BSP)

What is the Building Science Principles (BSP) Certificate of Knowledge?

The Building Science Principles (BSP) Certificate of Knowledge verifies basic knowledge of the building science behind house-as-a-system home performance. Building science demonstrates how various components of a home interact to affect its overall performance. After passing the 100-question online exam with a score of 70% or better, candidates will earn the certificate.

How do I access the BSP Reference Guide and how much does it cost?

The BSP Reference Guide can be accessed online as often as you like for an unlimited time. The guide may be purchased as an online text through the BSP registration system for $109 each ($99 until the end of 2022), or you may purchase the printed version for $129, plus shipping and handling ($119 through the end of 2022).

How do I take the BSP exam and how much does it cost?

The online exam costs $109 ($99 until the end of 2022.) It may be taken at any time. To access the exam, register on BPI's online portal and pay the exam fee. Alternatively, you may prefer to take the exam at a BPI Test Center. Click here to find a BPI Test Center near you. Please note that the exam is not refundable.

From BPI's perspective, the BSP exam is considered open book and the guide may be accessed during the exam. Please note that some organizations providing the exam might not allow open book access during the exam; open book access is at the discretion of the organization supplying the exam. The online exam may be taken at any time from a computer connected to the internet.

How long do I have to take the exam?

Candidates have up to one (1) year to take the exam after purchasing it online. Each exam attempt is a separate purchase. Once you log in to a computer and start the exam, you should plan for about two (2) hours to complete the exam. The BSP exam should not time out as long as you remain logged in and connected to the internet. When you finish answering the questions, you will close out the exam session and receive your score.

What happens if I fail the exam?

Candidates may re-take the BSP exam at any time. BPI recommends studying the Reference Guide in depth before attempting to take the exam again. In addition, candidates may wish to get training from an independent training organization.

After I pass the BSP exam, am I BPI certified?

No, only BPI Certified Professionals may claim to be BPI certified.

The Building Science Principles (BSP) certificate is not a BPI professional certification. The certificate is your first step into the world of home performance. Passing the BSP test does not replace the knowledge, skills or abilities of BPI Building Analysts, or other BPI Certified Professionals.

BPI Certified Professionals pass rigorous written and field practical exams, earn Continuing Education Units and re-certify every three (3) years to maintain best practices in building science. To learn more about BPI professional certifications, check out our available certification types.

Will the BSP certificate qualify me to assist others with their home performance projects?

The BSP certificate will qualify you to provide general advice to homeowners seeking information about home energy audits and retrofits. It will not qualify you to perform diagnostic tests associated with energy audits, or to carry out retrofit work. You will be able to recognize potential home performance problems, and to know when to call in an expert BPI Certified Professional. You can learn more about BPI's Professional Certifications here.

Certified Professionals

Who can become a BPI Certified Professional?

Anyone over the age of 16 may sit for a BPI exam. Anyone under 18 years of age will need to submit a BPI Parental or Guardian Consent and Waiver of Liability Form prior to sitting for a BPI exam.

While no formal experience is necessary to participate in most exams, we strongly recommend that you have some building performance experience and seek training from an independent training organization before taking any BPI certification exams.

To achieve certification, candidates must pass the tests associated with the certification, which could include an online and/or field exam. Tests must be administered by a proctor and be taken at a BPI Test Center.

What happens if I fail the exam? Can I retake it?

BPI is raising the bar in home performance contracting. The online and field exams are challenging - not everyone passes. Those who are unsuccessful on the exams can schedule to retake them.

You may make six (6) attempts to take and pass the online exam and six (6) attempts to take and pass the field exam in a one (1) year period. The year begins at the date of your first attempt. You make up to five (5) additional attempts in the ensuing year. Once you have made six (6) attempts, you must wait until a complete year has passed to try again.

The Building Analyst and Envelope certifications will no longer be available as of May 31, 2023.  Anyone attempting these certifications must complete the certification process, including retaking exams, by May 31, 2023.


Can I see my exam results online?

How can I access my ID card and certificates?

Certificates can be printed from the Certificates tab in your account. ID cards can be printed from the dropdown menu under your initial icon in your account.

What is BPI's recertification policy?

BPI's recertification policy recognizes the value of work experience, training and education in maintaining competence in home performance contracting. Under some circumstances, if you have verified work experience, you can eliminate the need to retake the field exam.

BPI's Continuing Education policy places a premium on updating knowledge, skills and abilities with latest industry best practices. Under some circumstances, by earning a certain number of qualifying Continuing Education Units (CEUs), you can waive or reduce online exam requirements when it is time to recertify.

For complete information, see the Certification Renewal Policies.

Application for BPI Certification Renewal

How does the recertification policy apply to BPI Proctors?

BPI Field Proctors who are certified in any of the Core and Multifamily certifications and remain in good standing during the entire certification cycle are not required to take a field exam. They are required to take only the online exam, while HEP proctors are required to take the field exam toward recertification. To bypass the online exam, BPI Proctors certified in Core and Multifamily certifications need 30 relevant CEUs (or 24 for the HEP certifications with the exception of Retrofit Installer, which requires 30 CEUs).

Proctors can find additional information, including the BPI Proctor Certification Renewal Policy document and the Application for BPI Certification Renewal - Proctors, in their proctor account.

To waive the field exam requirement for recertification, how can I prove my work experience?

Practitioners and trainers must prove a minimum number of hours of relevant technical field experience within the three (3) years during which they were certified related to the certification being renewed.

To prove this experience, print a copy of the sample template letter on the application on your company letterhead. Describe your technical field experience and have your supervisor sign this letter.

Self-employed individuals should use the sample template letter on the application to prove their work experience.

To waive the online exam requirement for recertification, how can I earn Continuing Education Units (CEUs)?

How do I become a CEU Provider?

If you go to your CEU Provider Account, you can register to become a CEU Provider. You can immediately start to submit courses. Please review BPI's CEU Provider Policy and CEU Policies and Procedures for detailed information about how to submit and information on how BPI awards credits.

Healthy Home Evaluator (HHE)

What is needed to obtain the Healthy Home Evaluator certification?

The Healthy Home Evaluator (HHE) certification builds on other BPI certifications.

You must have one of the following certifications prior to sitting for the HHE certification exam:

If my BA, BA-P, MFBA, EA, or QCI certification lapses, will I need to retest for the Healthy Home Evaluator certification?

If your prerequisite certification (BA, BA-P, MFBA, EA, or QCI) lapses, so will your HHE certification. Once you reactivate your prequiresite certification, your HHE certification will automatically reinstate, as long as your HHE certification date has not expired.

How long is the certification good for?

The HHE certification is good for three (3) years.

Is training required for the HHE certification?

Training is not a prerequisite for taking the HHE exam. However, one of the four (4) prerequisite certifications must be achieved prior to taking the exam for the HHE.

Is there a data collection form? How do we document and report an evaluation?

Several software options are on the market, such as Healthy Housing Solution's Healthy Home Check-Up and HUD's Healthy Home Rating System. There may also be local options.

Home Energy Professional (HEP) Certifications

What are the Home Energy Professional (HEP) certifications and what classifies them as advanced?

The HEP certifications demonstrate advanced competency through work experience prerequisites and rigorous written and field exams. Prerequisites include documented, industry-specific work experience, education and training.

These certifications also meet the global benchmark for quality personnel certifications across all industries - the ISO 17024 standard, as accredited by the American National Standards Institute (ANSI).

Do the HEP certifications replace any of BPI's other certifications?

The HEP certifications do not replace BPI's existing certifications. They are tailored to the specific job tasks of each role: Energy Auditor, Retrofit Installer Technician, Crew Leader, and Quality Control (QCI) Inspector. Each certification has its own significant work experience prerequisites.

How is the HEP Energy Auditor certification different from the Building Analyst certification?

The Energy Auditor (EA) certification is the next step up on the career ladder from Building Analyst (BA). The BA certification verifies that the worker has a foundation in diagnostic and analytical building science needed for a variety of career paths in the home performance industry, while the EA certification is specifically tailored to the job task of energy auditing.

The EA verifies the diagnostic and analytical skills needed to perform an energy audit, and then goes further. Among other things, the EA also verifies, through prerequisites, that the worker has software modeling skills, previous work history in doing energy audits, and can develop a scope of work to implement home performance measures in homes.

Bonus: As of January 1st, 2023, obtaining the Energy Auditor (EA) certification also allows the opportunity to be granted BPI's Building Analyst Technician (BA-T) and Building Analyst Professional (BA-P) for a certification fee. Once you become EA certified, you will receive an email with instructions on how to take advantage of this benefit. The Building Analyst certification is no longer issued to Energy Auditors.

What is the difference between the HEP Retrofit Installer Technician certification and the Air Leakage Control Installer?

The Air Leakage Control Installer certification was developed to evaluate a candidate's fundamental level of skill in the installation of appropriate materials only used to reduce air leakage in a typical home.

The advanced Retrofit Installer Technician certification is geared toward experienced technicians who have been in the field and can demonstrate a wider range of skills, such as the installation of doors and windows as well as insulation and air sealing materials.

What is the cost of the HEP exams?

Prices are set by the Test Centers. Please contact them for pricing.

What are the prerequisites for HEP certifications?

Prerequisites differ for each of the four (4) HEP certifications, but will generally include education, work experience, training, industry certifications and more. All prerequisites must be submitted with the HEP application to at least two weeks prior to taking the certification exam and, once approved, BPI will send approval letter to candidate to provide to the BPI Test Center. 

Click below to view the prerequisites for each HEP certification:

How can certification candidates prove their work experience to meet the prerequisite requirements?

For company employees

BPI accepts a signed certificate or a signed letter, on company letterhead, from current and/or past employers documenting work experience. For the applicant's convenience, a standard template letter is included with all four (4) certification applications. Simply print the template on company letterhead, fill out the requested information and have it signed by a supervisor.

For individuals who are self-employed, BPI accepts a letter containing:

  • An Employer Identification Number (EIN) or other documentation showing how long your company has been in business.
  • Number of jobs completed over the last year, including customer contact information and a brief description of each job (e.g. energy audit, air sealing, insulation). BPI will randomly contact customers to verify information given.
  • For those documenting energy audits completed, include documentation showing us PO of blower door and pictures of equipment, along with some completed examples of the reports issued to the customer for the energy audit.
What are the requirements for BPI Test Centers to administer the HEP exams?

BPI Test Centers that have approved HEP written and field proctors either on staff, or contracted, can administer HEP exams. These Test Centers must have the Energy Auditor minimum lab or home requirements available. Retrofit Installer Technician and Crew Leader prop submissions must be pre-approved.

Please see Section 7 of the BPI Test Center Policies and Procedures for further details on test site requirements for each designation.

What qualifications are necessary to proctor the HEP field exams?

All proctors must earn the HEP certification to proctor the applicable HEP exam. Proctors that have not previously proctored HEP field exams must also attend a mandatory orientation webinar to get approved to conduct HEP field exams.

What are the test site and prop requirements to administer the HEP field exams?

BPI Test Centers and/or Proctors must provide labeled photos or video of the system criteria or prop criteria outlined for each designation to ensure that the minimum guidelines for each are met. If the photos show that the criteria have been met, a notice of approval and site approval ID number will be sent to the BPI Test Center to be used on all testing forms. Prop plans and minimum system criteria are available to any BPI approved Test Center and/or Proctor that would like to administer the field exams through the test center and proctor account. Please send any prop or lab photos and any questions to

Photos and video must be submitted a minimum of two weeks in advance for review, comments and approval prior to administration of any HEP field exam. Online exams may be administered by any BPI approved online proctor and do not need prior site approval.


What is the BPI Rater program?

The BPI Rater Program qualifies Home Energy Score assessors to perform a visual assessment that educates homeowners about their home's energy efficiency. Assessors then provide cost-effective recommendations to reduce the amount of energy that homeowners waste on inefficiencies.

What is the Home Energy Score?

Developed by the U.S. Department of Energy (DOE), the Home Energy Score provides a standardized method for quickly assessing a home's building envelope and major energy systems. This score, on a scale of 1-10, allows comparisons between homes regardless of location in the U.S. In addition to providing a score, assessors also provide a prioritized and customized list of energy improvements, and their estimated cost savings, for the customer's home.

What is BPI's role in administering the Home Energy Score?

BPI was DOE's first national Home Energy Score Partner. Local and state governments, utilities, non-profits and other home performance industry organizations can become Home Energy Score Partners. If a local partner is not available in your area, you can partner with BPI anywhere in the nation.

What does a homeowner get and what does it cost for them to get a Home Energy Score report?

A Home Energy Score report contains:

  • A numerical score of the house on a scale from 1 to 10, where a score of 1 indicates the home needs extensive energy improvements and a score of 10 indicates excellent energy performance
  • The home data, also referred to as home facts, collected by the Qualified Assessor and inputted into the Scoring Tool to generate the score and improvements
  • Cost-effective energy efficiency improvement recommendations customized to the home

The fee schedule for the Home Energy Score Assessment is determined by the Rater Company.

Who can provide a Home Energy Score?

Qualified Assessors working under a partner, either local or a national partner, like BPI, can conduct home assessments and produce the Home Energy Score for homeowners.

How much does the Home Energy Score exam cost?

There is no fee for the training and testing. However, there is an annual fee to become a BPI Rater Company. Please see Appendix B (on page 18) of the BPI Rating Program Policies and Procedures.

Once I become a BPI Rater, how will homeowners find me?

Homeowners may use BPI's Contractor Locator Tool to find BPI Raters and BPI Certified Professionals. When you join BPI's Rater Program, your information is automatically added to the locator tool.


What are the BPI standards?

BPI is an American National Standards Institute (ANSI) accredited national standards development organization for the energy efficiency and weatherization industry.

BPI develops certifications based on upholding these standards and creating consistency throughout the workforce. BPI currently provides standards on home energy auditing, standard practice for the basic analysis of buildings and more.
