Georgia continues to stand out when it comes to green residential construction.
The state ranked No. 5 nationally for both single-family and multifamily NGBS Green Certification activity in 2025. That puts Georgia alongside some of the country’s most active housing markets, including Texas, Florida and North Carolina.
The numbers also reflect how much the green building movement has grown. More than 120,000 homes earned NGBS Green Certification in 2025, bringing the total number of homes certified through the program to more than 750,000 since its launch in 2009.
For Georgia’s builders and developers, that growth points to a housing market where building performance is becoming an increasingly important part of the conversation.
What Is NGBS Green Certification?
The National Green Building Standard (NGBS) gives residential builders and developers a framework for incorporating sustainable, high-performance practices into homes and communities.
But certification goes beyond checking a box for green features.
NGBS Green Certification is an independent, third-party verification program administered by Home Innovation Research Labs. A trained verifier evaluates a project against the standard, giving builders a way to demonstrate that sustainability strategies are actually incorporated into the home or development.
The program applies to a wide range of residential projects, including single-family homes, townhomes, multifamily buildings, renovations and land developments.
Projects are evaluated across six areas:
- Lot Design, Preparation and Development
- Resource Efficiency
- Energy Efficiency
- Water Efficiency
- Indoor Environmental Quality
- Operation, Maintenance and Building Owner Education
That broad approach is what makes NGBS different from a certification focused on a single feature or building system. The goal is to consider how the pieces work together, from the way a site is developed to how efficiently a home operates once someone moves in.
What Does Green Building Mean for Homeowners?
For buyers and residents, green building can sound technical. In practice, many of the benefits are surprisingly everyday.
A more efficient home can use less energy and water. Thoughtful ventilation and material choices can contribute to better indoor environmental quality. Durable products and construction practices can help a home hold up over time.
Those details may not always be the first thing a buyer notices when walking through a new home, but they can shape the experience of living there.
That’s part of the appeal of third-party certification. Rather than simply describing a home as sustainable, NGBS Green Certification provides an independent process for verifying that specific practices and requirements have been met.
Georgia’s Role in Green Residential Construction
Georgia’s strong NGBS showing also fits into a broader push for sustainable housing across the state.
The Georgia Department of Community Affairs’ Qualified Allocation Plan recognizes NGBS Green Certification alongside other established green building programs, including EarthCraft, Enterprise Green Communities and LEED for Homes.
That recognition is particularly relevant for developers working on affordable housing, where energy and water efficiency can have a meaningful impact on long-term housing costs.
NGBS is also gaining ground nationally. According to Home Innovation Research Labs, 30 state housing finance agencies recognized or rewarded NGBS Green Certification through their 2025 programs.
Building for Performance
Green building has evolved well beyond solar panels and energy-efficient appliances.
Today’s high-performance homes can incorporate everything from water-saving fixtures and efficient mechanical systems to responsible site planning, improved indoor air quality and durable materials. NGBS brings those strategies together under one residential building standard and provides third-party verification along the way.
For Georgia, continued growth in NGBS Green Certification suggests builders and developers are paying attention to more than how a home looks on opening day. They’re also considering how it performs over time.
And with Georgia once again ranking among the nation’s most active NGBS markets, that conversation is only getting bigger.

What does NGBS certification cover?
The National Green Building Standard covers six areas: Lot Design, Preparation and Development; Resource Efficiency; Water Efficiency; Energy Efficiency; Indoor Environmental Quality; and Operation, Maintenance and Building Owner Education. The standard can be applied to single-family homes, multifamily buildings, townhomes, renovations and land developments.
What are the NGBS certification levels?
NGBS Green Certification for homes and buildings has five levels: Certified, Bronze, Silver, Gold and Emerald. Land developments can earn one- through four-star certification. The level achieved depends on the sustainability practices and points incorporated into the project.
Why is NGBS certification important for homeowners?
NGBS certification can give buyers and residents an independently verified way to identify homes designed with building performance in mind. Depending on the project, that can include features that improve energy and water efficiency, indoor environmental quality and durability.
