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.

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.
