Become an Accredited Verifier for the National Green Building Certification Program

Read all of the following information before submitting the verifier application.

The NAHB Research Center is seeking interested, qualified individuals to become National Green Building Certification accredited verifiers. As the sole certifying body, the NAHB Research Center is responsible for training and accrediting eligible individuals to verify that homes across the country meet the criteria of the national green building certification. Individuals may work for larger organizations, but verifiers are accredited on an individual basis.

To become an accredited verifier, an individual must first meet eligibility prerequisites. Then the individual must complete verifier training and pass an accreditation test. The fee for the on-line training and testing is $125 paid in advance of the training. This fee also covers the first year listing fee. Once the test has been successfully completed, the individual must submit the other required documentation to the NAHB Research Center to become a listed, accredited verifier.

Verifier Tasks

Accredited verifiers perform the following key functions:

  • Executing a verification agreement with the builder. This defines specific verification fees, number of meetings with the builder, number of inspections of any building presented for certification, and any expected performance tests of homes under construction.
  • Confirming with the builder that the appropriate scoring method/tool correctly shows the points claimed by the builder and that both parties understand the level (Bronze, Silver, Gold, or Emerald) of green building certification that is being sought by the builder.
  • Deciding, with the builder, whether an initial document review of the builder's supporting documentation is required before the initial (pre-drywall) site inspection. Verifiers complete such document review, if needed, and record results.
  • Scheduling the first (pre-drywall) site inspection and notifying the certifying agent (the NAHB Research Center) of this scheduled date.
  • Conducting the pre-drywall site inspection and documenting the results.
  • Documenting any performance tests (i.e. duct leakage test results) done on this building by the verifier or by others.
  • Scheduling the second (final) inspection and notifying the certifying agent (the NAHB Research Center) of this scheduled date.
  • Including documentation of any performance tests (blower door or flow hood test results) done on this building by the verifier or by a qualified professional.
  • Conducting the final site inspection and documenting the all results (documentation review, first and final site inspections) and any verifier comments into the appropriate form for confirmation by the certifier.

The course covers the protocol for verifying that a house meets the national certification program requirements, and is intended to ensure all verifiers across the country evaluate homes in a consistent manner. This training does not include developing the "green" expertise each prospective verifier is expected to have as a prerequisite.

Training Options

  • On-demand 24/7 training over the Internet. On-demand sessions are available 24/7 to those candidates who apply online and meet the verifier training prerequisites. There are three training modules that can be done all at once, one at a time, or in parts of modules, depending on the user’s preference. The amount of time required for each module will depend on the individual student. The testing module is available after completion of the training modules, but must be completed in one sitting.
