Energy Efficiency
Earth Advantage Certified Homes
What Is Earth Advantage?
Earth Advantage is a nonprofit, third-party certification program based in Portland, Oregon. It sets a higher standard for residential construction — verifying that certified homes go beyond minimum building codes in five key areas: energy efficiency, indoor air quality, resource efficiency, environmental responsibility, and water conservation.
Earth Advantage offers three certification tiers: Silver, Gold, and Platinum. Every Stone Bridge Homes NW home earns Earth Advantage certification, independently verified through a series of inspections and performance testing during construction.
Why It Matters
Certification isn’t a marketing label — it’s a verified commitment to building homes that perform better for your family and for Oregon. Here’s what Earth Advantage certification means in practical terms:
Lower Energy Bills
Earth Advantage certified homes are designed and built for energy efficiency from the ground up. High-performance insulation, efficient HVAC systems, energy-rated windows, and LED lighting throughout — all contribute to significantly lower utility bills compared to standard code-built homes. Earth Advantage even offers an Energy Bill Guarantee for certified homes.
Healthier Indoor Air
Low-VOC building materials, advanced ventilation systems, and air filtration designed for Oregon’s unique climate — including wildfire smoke season — mean the air inside your home is cleaner and healthier. For families with allergies, asthma, or sensitivity to air quality, this is a meaningful difference.
Durability and Fire Resistance
Earth Advantage standards emphasize materials and building practices that increase the lifespan and resilience of your home. Fire-resistant materials, moisture management systems, and durable exterior finishes mean your home is built to withstand Oregon’s varied climate — from wet winters on the west side to hot, dry summers and wildfire risk in Central Oregon.
Water Conservation
Efficient fixtures, smart landscaping practices, and water-conscious design reduce your home’s water footprint without sacrificing comfort or convenience.
Environmental Responsibility
Building with sustainability in mind means less waste during construction, responsibly sourced materials, and a smaller overall environmental footprint. When you choose an Earth Advantage certified home, you’re choosing a home that’s better for the planet.

Earth Advantage at Stone Bridge Homes NW
Stone Bridge Homes NW has been building Earth Advantage certified homes since the program’s early years. Our commitment to the standard isn’t a recent addition — it’s foundational to who we are. President Kelly Ritz, a former environmental attorney, built the company with sustainability as a core value, not an afterthought.
That commitment has been recognized year after year. Stone Bridge has received the Earth Advantage Most Gold Certified Homes award multiple years running, earned the Volume Builder of the Year award in 2020, and was inducted into the Earth Advantage Hall of Fame. Our construction managers have also been individually recognized, including the Construction Superintendent of the Year award.
What You’ll Notice
You don’t need to understand building science to appreciate an Earth Advantage certified home. What you’ll notice is simple:Â
Energy
Your utility bills are lower.
Comfort
Your home feels comfortable year-round.
Air
The air inside smells clean.
Peace of Mind
You have the peace of mind that comes from knowing your home was built to a higher standard — verified by an independent third party, not just promised by a builder.

Stone Bridge Homes NW is a multiple Green Builder of the Year award winner and a member of the Earth Advantage Hall of Fame — one of a handful of builders nationwide to earn that distinction.

What Our Homeowners Say
"
Mary J | Autumn Sunrise
I chose Stone Bridge Homes for the construction of my new home in Oregon because of their reputation for building homes of exceptional quality. You can see the quality in the workmanship both inside and outside of their homes. Standard with their homes are details one would expect to find in an upscale, custom home. From lot selection to construction options to design components, I found the Stone Bridge representatives were always transparent with me about plan changes and the wide selection of design options available.Â
Janet S | Frog Pond Ridge
We've been in our new Stone Bridge home for about six weeks now, long enough to be able to reflect both on the process and the end result. We'd never built a home before, but the changing needs of our multigenerational family started us down this road. We were very happily surprised with the number of options and customizations available to us through Stone Bridge, and the process that we entered into with tno small amount of repidation turned out to be one that was actually fun and enjoyable.Â

I wanted to take a moment to share what a pleasure it has been working with Erin from Home Warranty after purchasing our Northwest Stone Bridge home at Stevens Ranch. Even with a brand-new home, there are always a few touch-ups and small items that need attention. Erin made the entire process incredibly smooth and seamless from start to finish. She was consistently professional, prompt, thorough, and extremely personable throughout every interaction. Her communication and dedication to ensuring everything was handled properly truly stood out and made the experience stress-free. We sincerely appreciate all of her help and outstanding customer service.
Heidi L | Frog Pond Terrace
Our experience with Stone Bridge has been excellent. Communication is always there and answered timely. The home is well built with all the upgrades and changes we requested. So impressed that when we drove by and the team was pouring the foundation they shouted that they work for the best and they took such pride in their work. We feel we got a quality build with attention to detail from the ground up. Thank you!
Andrew | Frog Pond Vista
It was a pleasure working with Stone Bridge. You were extremely professional and knowledgeable. I will for sure recommend Stone Bridge to future friends, family, and colleagues.
Mike | Arlington Heights
Stone Bridge gave us the flexibility we were looking for. We didn’t want a cookie-cutter home, and with Stone Bridge, we could make the home our own.
Matt | Autumn View
We’ve been extremely satisfied with the quality, craftsmanship, and service. The floor plan was perfect for our growing family.
Bridge and Ryan | Reed's Crossing
My wife Bridge and I wanted to send our heartfelt thanks and gratitude to you for our wonderful Stone Bridge home in Reed’s Crossing. We have been here almost 5-years now and our home is just perfect. We’re so grateful that we had the opportunity to purchase it, and that your company was so accommodating to us.
Robert L | Autumn Sunrise
A change in address and walking into your new home should be a joyful moment. This is what we have experienced in our last 3 moves in the past 27 years. All our previous homes were built by Stone Bridge. Happiness is when you see what you designed. What your vision is. Stone Bridge has built a Palace for me and my family. They took the input from us and our son and built it to OUR specifications. I wanted a sink in my office where I could brew coffee my way. My wife wanted a second island in HER custom kitchen.Â
Marcella M | Frog Pond Ridge
5 Stars across the board - from the quality of home, sales team, and support after closing, Stone Bridge Homes has more then exceeded our expectations. As a Realtor who has sold numerous new construction homes, I can confidently say this experience was not the norm, but I know it's the norm for Stone Bridge. Travis and team in the sales office at Frog Pond couldn't have been more on top of the process, answering all of our questions and meeting our concerns with nothing but grace and solution. My family is honored to own a Stone Bridge home for years to come.
Matt S | Autumn View
I'm happy to share how pleased my wife and I are with our Stone Bridge Home. This is the first house we've purchased and have been extremely satisfied with the quality, craftsmanship and service. Of all the homes we considered, our Stone Bridge home provided the best floor plan to meet the needs of our growing family. We've appreciated the detail and thought put into the design and have felt right at home since day one. For those looking to invest in a new home, we strongly recommend Stone Bridge Homes NW and the phenomenal staff who ensure your satisfaction.
Rama K | Abbey Woods Terrace
Exceptional Home Buying Experience!
From the initial consultation to the closing day, the entire process was smooth. The team was incredibly knowledgeable, patient, and attentive to my needs. They guided me through every step of the process, answering all of my questions and addressing any concerns promptly. I felt supported and well-informed throughout the entire journey. Thanks to their expertise, I found the perfect home for our needs. I highly recommend Stone Bridge Homes NW to anyone in the market for a new home!
Patrick W | Evergreen Gardens
Our 90 day warranty list looks to be done and I wanted to take an opportunity to provide some positive feedback for Scott. In this line of work, I'm certain it can be a thankless job at times as many customers want items to be done "instantly". I understand these things take time and especially contractors have to schedule warranty work amidst the construction projects that are going on as well.Â
Phillip and Claudia | The Parks at Forest Grove
Upon living in our home for a year, we are happy we chose Stone Bridge for a variety of reasons. The choice in design and a variety of features of the home as well as the quality of construction. The 90 day warranty was really a great asset. The one-year warranty satisfied those small details that affords confidence in Stone Bridge. At a phone call, Scott and Misty addressed any concerns that emerged. In every interaction, they have been pleasant, helpful, and responsive. The people working for Stone Bridge are respectful, helpful, and professional in every interaction.
