A Net-Zero Luxury Home for Aging-in-Place Integrates Geothermal and Solar 

My dad was a developer, and my stepdad was a forest ranger," says Troy Johns, owner of Urban NW Homes in Vancouver, Washington. "I grew up with both of them. Put them together, and you get me: A developer and builder dedicated to sustainability." You also get The Brazadian, a net-zero custom home with a luxurious yet rugged aesthetic, powered by geothermal and solar, which Troy and his wife Allison built as their forever home.

Located on 15 acres near Ridgefield, Washington, the four-bedroom home has 4,500 square feet of one-level living.

The foyer, two bedrooms, a media room, and a home office are on the same level as 1,600 square feet of outdoor living areas (300 square feet of the outdoor space is covered), for aging-in-place with seamless access to the outdoors, gardens, and native vegetation. The home's 1,500-square-foot upper includes two bedrooms and a bonus room above the garage.

The home's "unique look," Johns says, was inspired by a golf resort in southern Oregon. "When we visited the golf resort, we were struck by the architecture and wanted something similar for our new home." 

The Johns' home received Emerald-level certification from the Home Innovation Research Lab's National Green Building Standard (NGBS). "That's NGBS' highest possible rate and the most rigorous to achieve," Johns says. With its net-zero energy efficiency and repurposed materials, the home sets a new standard for healthy, conscious luxury. 

We often tell clients you can have a luxury home and be responsible about it," Johns says. "When we show them our home—and we have tours all the time—visitors get excited about the possibilities.

Clean Indoor Air, Recycled Materials 

The geothermal system heats the European tile floors on the main level via a GeoLink WaterFurnace. The couple had the home's doors custom-built, or they used reclaimed doors. Artisans created custom shutters from salvaged rodeo chutes. The entries for the master bedroom doors came from a vintage apartment in Philadelphia. 

Some of the home's natural hand-plastered walls have elegant hand-stenciled designs. All of the bath fans are energy-efficient models. The wood used inside was locally sourced, then milled and stained with low-VOC products on-site. The sawdust was mulched back into the soil. The home uses LED lights throughout. The home also operates with a smart-home automation system for energy savings. 

Making Adjustments 

The Johns family completed the home two years ago. "We designed the house for four years before building it, so we thought out everything ahead of time," Johns says. "We didn't have much to re-do."

There is, however, an adjustment the HRVs made possible. "The geothermal heated floors are tile and toasty and warm. But we're always learning," he explains. "We figured out that when you build a house so airtight, it doesn't lose a lot of heat, and the floors don't kick on. Now we have a comfortable home, but the floor can be slightly cool. HRVs, however, help circulate the air and kick the floors back on. Without the HRVs, the floor would stay cold."

"We hope more people will soon realize how their home affects them mentally and physically, as well as how their home impacts the global environment." As a showcase and a family home, The Brazadian is one step in the right direction.
