Guidelines for Home Energy Professionals Certifications

As part of the Guidelines for Home Energy Professionals project, the U.S. Department of Energy (DOE) collaborated with trainers and technicians from across the home performance industry to develop high-quality, nationally recognized professional certifications. Learn more about the certification blueprint, how to get certified, and resources for training centers below.

Certification Blueprint

The new certifications require experienced home energy professionals to demonstrate comprehensive knowledge, practical skills, and technical proficiency in the four most common job classifications in the DOE Weatherization Assistance Program (WAP) and home energy upgrade industry: energy auditor, retrofit installer technician, crew leader, and quality control inspector.

To establish the framework, or blueprint, for the four Home Energy Professional certifications, DOE's National Renewable Energy Laboratory (NREL), brought together more than 40 industry-nominated volunteers to define the general requirements of each (e.g., prerequisites, exam structure, practical application, and re-certification requirements). Those requirements are based largely on:

  • Standard work specifications (SWS) for single-family homes—Developed by NREL in collaboration with industry experts and subjected to extensive public/industry review, these specifications define the minimum acceptable outcomes for any weatherization or home performance task to be effective, durable, and safe.
  • Job Task Analyses (JTAs) for single-family home energy upgrades—Developed by NREL and validated by more than 800 industry experts, JTAs define the knowledge, skills, and abilities required to be successful in each of the four primary energy upgrade job classifications. JTAs also serve as a foundation for accredited industry training programs.

The certification blueprints were produced in accordance with the ISO 17024 Standard for the quality and rigor of personnel certifications.

With ISO 17024-accredited certifications and training programs based on the SWS and JTAs, weatherization and home performance contractors will know the caliber of the people they are hiring, consumers will know that these workers have proven their ability to do quality work, and workers will have the professional status that comes with being nationally certified.

How to Get Certified

The Building Performance Institute (BPI) is the first third-party organization licensed to deliver the Home Energy Professional Certifications.

Because these certifications are for experienced professionals, candidates must meet prerequisite criteria to be eligible to take the exams. For detailed registration information, read BPI's Registration Instructions for the Home Energy Professional Certification Exams.

To apply to take the certification exams, visit the BPI website.

Resources for Certifying Bodies

NREL licenses the Home Energy Professional Certification blueprints to American National Standards Institute (ANSI)–accredited certification bodies through a process that complies with ISO 17024. To learn more about becoming licensed to deliver the Home Energy Professional Certifications, contact NREL.

Resources for Training Centers

For training centers interested in developing curricula that prepares students for the Home Energy Professional Certification exams, the Weatherization Assistance Program Technical Assistance Center (WAPTAC) provides standardized curricula for each of the four job classifications. Additionally, training centers will want to refer the Job Task Analyses (JTAs) for single-family home energy upgrades.
