NGBS Certification

Third-party verification for healthier, more efficient homes and communities

RunBrook helps builders, developers, and project teams pursue National Green Building Standard certification with practical guidance, verification support, and building performance expertise. Whether your project includes a single-family home, multifamily development, mixed-use residential project, or residential community, our team can help determine the right certification path and support the process from early planning through final verification.

As experienced NGBS Green Verifiers, RunBrook provides the third-party support needed to help project teams document sustainable design, construction quality, energy efficiency, indoor environmental quality, and long-term building performance.

Why NGBS certification matters


Build homes that are healthier, more efficient, and more marketable

NGBS certification provides independent, third-party verification that a home, apartment building, or land development is designed and built to meet recognized green building practices. For builders and developers, certification can help demonstrate a commitment to quality, sustainability, and performance while giving residents confidence in the places they live.

  • NGBS strategies can support fresh air ventilation, improved indoor air quality, reduced pollutants, and better moisture control.

  • Energy and water efficiency strategies can help reduce utility costs and support more efficient building operation.

  • NGBS encourages durable construction practices and product selection that can help reduce maintenance needs over time.

  • Certification helps communicate the value of a high-performing, third-party verified home or community.

  • NGBS includes practices related to site design, resource efficiency, water conservation, and responsible land development.

  • NGBS certification can connect with related services such as energy modeling, HERS ratings, blower door testing, duct leakage testing, and field inspections.

What is NGBS certification?

The National Green Building Standard, or NGBS, was established by Home Innovation Research Labs and is approved by ANSI as an American National Standard. NGBS certification provides independent, third-party verification that residential buildings and land developments are designed and built to achieve high performance in key areas of sustainability and building performance.

  • Site design

  • Resource efficiency

  • Water efficiency

  • Energy efficiency

  • Indoor environmental quality

  • Building operation & maintenance

Together, these categories help project teams create homes and communities that are more efficient, comfortable, durable, and environmentally responsible.

RunBrook’s role

Strategic guidance from experienced NGBS Green Verifiers

RunBrook can help project teams determine whether NGBS, LEED, or another green building rating system is the best fit for the project’s goals, budget, timeline, and certification requirements. If NGBS is selected, our team can continue to guide the project through the certification process as an NGBS Green Verifier.

Our experience working on numerous NGBS projects gives us a practical understanding of the certification process, documentation requirements, field verification needs, and common challenges that can arise during design and construction.

RunBrook can support your project with:

  • NGBS certification strategy

  • Rating system comparison and guidance

  • NGBS Green Verifier services

  • Design phase planning

  • Documentation coordination

  • Field inspections and verification

  • Energy modeling and HERS rating support

  • Blower door and duct leakage testing

  • Coordination with builders, developers, architects, engineers, and contractors

  • Final verification and certification support

NGBS Green Verifier services

Third-party verification throughout the certification process

An NGBS Green Verifier provides independent verification that the project is meeting the selected NGBS practices and certification requirements. RunBrook works with project teams to review documentation, verify field conditions, coordinate required inspections, and support the certification process from start to finish.

As your NGBS Green Verifier, RunBrook can help:

  • Review project goals and certification targets

  • Identify applicable NGBS practices

  • Communicate verification expectations to the project team

  • Coordinate inspections at key construction milestones

  • Verify installation of selected green building measures

  • Support documentation requirements

  • Confirm testing and performance verification needs

  • Help prepare the project for final certification submission

What NGBS evaluates

Six key areas of green building performance

  • NGBS considers how the project relates to its surrounding site, including land development practices, community design, stormwater strategies, landscape choices, and site impact reduction.

  • This category focuses on the efficient use of materials and resources, including framing practices, material selection, waste reduction, durability, and responsible construction practices.

  • NGBS encourages strategies that reduce indoor and outdoor water use through efficient fixtures, irrigation practices, landscape design, and water-conscious building systems.

  • Energy performance is a major part of NGBS certification. This may include insulation, windows, HVAC systems, air sealing, duct sealing, water heating, lighting, appliances, and energy modeling or HERS rating support.

  • This category focuses on healthier indoor environments through ventilation, moisture control, pollutant reduction, filtration, material choices, and improved indoor air quality practices.

  • NGBS also considers how the building will be operated and maintained over time, including homeowner or property manager education, maintenance planning, manuals, and performance guidance.

Certification process

A clear path from strategy to verification

Step - 1 Define project goals

We begin by reviewing the project type, sustainability goals, budget, timeline, and desired certification level.


Step - 2 Develop a NGBS strategy

RunBrook helps identify target practices, documentation needs, field verification requirements, and opportunities to align certification with project design and construction plans.


Our team works with the project team to verify selected measures, coordinate inspections, collect documentation, and support required testing.
