How does a home become certified?
National Green Building Certification assures homeowners and the community that your projects meet the requirements of the NAHB Model Green Home Building Guidelines, and truly are green. Builders interested in having their homes certified follow the steps outlined below.
Builder Process for Green Home Certification
| Step 1: |
The builder scores the home to be certified using the online Green Scoring Tool. |
| Step 2: |
Export final Designer's Report from Green Scoring Tool and save locally as an Excel file. |
| Step 3: |
As construction begins, select an accredited verifier.
If there is not an accredited verifier listed for your area, contact the National Green Building Hotline – (877) NAHB-GRN – to let the NAHB Research Center know and/or to suggest a potential verifier candidate in your area. |
| Step 4: |
Forward Designer's Report to selected verifier and schedule rough inspection. The Verifier's Resource Guide provides insight for the builder on how the verifier will inspect the home. |
| Step 5: |
Meet with verifier after rough inspection to sign off on Verification Report which will be sent to NAHB Research Center for review. |
| Step 6: |
Receive invoice for $200 home certification fee for NAHB members ($500 for non-members). |
| Step 7: |
Complete Program Participation Agreement and return to Research Center with required evidence of insurance. Documentation is included in a builder's application packet, available by calling (877) NAHB GRN or contacting us via e-mail.
Only one Agreement is required for each builder regardless of how many homes are ultimately submitted for certification. |
| Step 8: |
Schedule final inspection with verifier and sign off on final Verification Report including certificate information. |
| Step 9: |
After final report review and receipt of the certification fee, the NAHB Research Center will issue the Certified Green Home certificate. |
