Nation Green Building Standards FAQs

Your NGBS tax credit questions, answered.

A clear, easy-to-navigate resource that answers common questions about certification requirements, program guidelines, scoring, benefits, and the overall process from registration to final approval.

How much does NGBS cost?

Costs depend on project size, scope, target level, and verification needs. Budget for registration, verifier fees (inspections/document review), and any design upgrades to achieve credits.

How long does certification take?

NGBS runs alongside normal construction. With early planning and clean documentation, most timelines are driven by the project schedule itself.

Can existing buildings be certified?

The R&D Tax Credit is claimed by filing it on a timely submitted tax return, which can include extensions. This credit can also be retroactively claimed on amended tax returns, typically for up to the previous three tax years. To report the credit, businesses need to complete IRS Form 6765, titled “Credit for Increasing Research Activities,” for the tax year in which the qualified expenses were incurred. For business entities such as Sub-S Corporations and LLCs, the credit is passed through to the shareholders, who then report it on their individual Schedule K-1 forms.

Does NGBS compete with ENERGY STAR® and ZERH?

They’re complementary. ENERGY STAR® and ZERH focus strongly on energy performance; NGBS spans broader categories (water, resources, IEQ, operations). Many teams stack programs strategically.

What documentation will I need?

Expect plans/specs, product submittals, testing results, photos, commissioning/verification evidence, and installer/manufacturer documentation aligned to targeted credits.

Is recertification required?

Projects remain certified under the version pursued at the time. New versions are periodically released; future projects can use the latest version.

Do mixed-use buildings qualify?

Yes, for the residential portion. NGBS is designed for residential uses and residential components of mixed-use developments.

Will NGBS help with financing?

Some green financing products consider third-party certifications. Confirm current eligibility and pricing with your lender before design lock-in.
