Austin Home Achieves Top Ratings in Three Green Building Programs

House earned LEED-Platinum, NAHB-Gold, and Austin Energy Green Building 5-Star Certification, plus Energy Star qualification.

EcoHome Magazine’s latest Case Study is about as green as you can get - a home in Austin, Texas that was designed and constructed from head to toe, from roofing, to countertops, to windows, to flooring, in such a way that earned top-level certification in four different green building programs.

For such an incredibly complicated project, it’s no wonder that the home’s verifier Chip Henderson compiled a simple three-page spreadsheet that included the mandatory requirements of each program to help him get organized.

“We took a look at the four programs and folded them into one to-do list,” recalls Henderson, of San Antonio-based Contects Consultants and Architects. “We realized that if we stuck to this one to-do list, at the end of the day we’d cross the finish line with all four of the programs.”

And so it seems, Henderson’s organizational skills paid off: The 3,266-square-foot home obtained top ratings by the three most widely accepted green building programs in Austin: LEED-Platinum, NAHB Model Green Home Building Gold, and Austin Energy Green Building 5-Star. The house is also Energy Star-qualified.

Designed by Austin-based Barley & Pfeiffer Architects, the home features advanced framing techniques, spray-foam insulation, high-efficiency air conditioning, energy-efficient windows, low-VOC interior finishes, a tankless hot water heater, CaesarStone quartz countertops, dual-flush toilets, and compact fluorescent light fixtures. A 3-kW solar photovoltaic array on the southeast roofline of the home offsets energy consumption by 25%.

The open kitchen features integrated Miele stainless steel appliances and Caesarstone quartz countertops.

While certifying a home in three major green building programs plus Energy Star may seem like overkill, Henderson says there are marketing benefits to the approach.

“You’re supporting the regional program for the local recognition that your consumers may be familiar with and at the same time combining that with at least one national program,” he says. “Depending on how you’re marketing your company, it has some advantages.”

Those involved in the project said they learned a lot about the programs’ similarities and differences.

“All of the programs have a lot of commonality because the building science community’s consensus of what we need to be doing to really call a house high-performance is very similar,” Henderson says. “So it wasn’t like comparing apples to oranges, it was more like a Fuji compared to Pink Lady--just variations but not radically different.”
