National Green Building Standards

What is National Green Building Standard (NGBS)

The National Green Building Standard (NGBS) is a third-party verified certification program tailored to residential and mixed-use projects with residential components. It evaluates performance across multiple categories—including energy and water efficiency, resource use, indoor environmental quality, and operation/maintenance—to certify that a home or community meets defined, above-code sustainability criteria.

Who uses the National Green Building Standard?

Builders, developers, and design teams seeking a residential-specific green framework

Investors and lenders looking for transparent performance signals

Public and affordable housing stakeholders needing a recognized path to compliance or incentives

Which Projects Qualify?

If it’s built for people to live in—or it’s a residential portion of a mixed-use project—it likely fits an NGBS pathway:

How NGBS Certification Works

Core categories Lot/Development, Resource Efficiency, Water, Energy, Indoor Environmental Quality, and Operations/Maintenance.

Certification levels reflect total points achieved above mandatory measures: Bronze, Silver, Gold, Emerald.

Verification is required by an accredited NGBS Green Verifier (inspections commonly occur pre-drywall and at completion).

Plan & Register

• Define targets, select credits, and register the project

Design Integration

• Specify assemblies, systems, and details to meet mandatory + targeted credits

On-Site Verification

• Rough and final inspections by an accredited verifier; documentation submitted

Certification Issued

• Project receives its NGBS certificate and level

Why NGBS Matters for Developers & Investors

Marketability & Rentability

Certified projects signal lower utility costs, healthier indoor environments, and quality control—amenities that resonate with today’s renters and buyers.

Potential Access to Green Financing

Some lenders and programs recognize third-party green certifications in underwriting. NGBS can be among accepted options. (Always confirm current program rules with the lender.)

Incentives & Approvals

Many jurisdictions offer density bonuses, tax abatements, permit streamlining, or points in competitive funding when a project achieves a recognized green standard. NGBS provides a formal, audited pathway.

Risk Management & Future-Readiness

With evolving ESG expectations and local performance policies, NGBS helps demonstrate diligence and reduces the likelihood of costly retrofits later.

When Is NGBS Required?

While NGBS is voluntary, it can become effectively required when:

Seeking certain green financing products that recognize third-party certifications

Meeting affordable/LIHTC or public program guidelines that stipulate a green standard

Pursuing local incentives or entitlements tied to certification

Competing in markets where investors/tenants expect proven sustainability

NGBS FAQs

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?

Yes. NGBS includes renovation/rehab pathways for existing residential buildings.
