The Greenbuild LivingHome being constructed on the floor of this year’s Greenbuild International Conference and Expo in New Orleans is a first-of-its-kind demonstration home, not only because of its extreme performance goals but also for the team that converged to develop them. Some of the country’s top sustainability experts guided the home’s design and construction to meet LEED v4 Platinum and Energy Star v3 standards and to showcase Cradle to Cradle certified products and strategies modeled on the WELL Building Standard. Driving the project is modular home innovator LivingHomes, and project partner Make It Right advised the team on details and products that meet its own requirements for the harsh environment of New Orleans.
Project leaders Hanley Wood (BUILDER’s parent company) and builder/designer LivingHomes enlisted talent from Steven Winter Associates, InSpirit, Spruce Interiors, the USGBC, and title sponsor Propane Education & Research Council to integrate sustainable design, modular construction, energy and water efficiency, health, and resilience into the versatile home. After its stint at Greenbuild, the house will join Make It Right’s community of LEED Platinum homes in the city’s Lower 9th Ward. (The affordable housing nonprofit is the recipient of the 2014 Hanley Award for Community Service in Sustainability.)
Santa Monica, Calif.–based LivingHomes worked with Make It Right to learn how to safeguard the home against the challenges of the local climate. With seven years of experience building high-performance homes in the Crescent City, Make It Right has learned what works—and what doesn’t—in this hurricane-prone area. Its project managers have amassed detailed information about appropriate design and construction methods for their homes—with a laser focus on building science. Amy Sims, LivingHomes’ director of design, tapped Make It Right’s knowledge base and the collaboration yielded best practices for building a resilient home on a budget.
“We realized early on that with a few changes we could meet Make It Right’s criteria and install the home for one of their clients when it’s finished at the show,” says LivingHomes CEO Steve Glenn. “This is going to be a new model for us, optimized to their needs.”
LivingHomes’ designers took every step possible to protect the 1,450-square-foot home from moisture. To help control the area’s notoriously rainy, humid weather, Sims speced Metal Sales standing seam pitched roofs with 2-foot overhangs and covered porches that direct water away from the one-story house. DuPont Tyvek’s DrainWrap housewrap and flashing system, Andersen windows, Jeld-Wen doors, and James Hardie horizontal lap siding, along with areas protected by Metal Sales exterior cladding, beef up the home’s ability to combat the elements.

Inside, the battle against moisture continues with Panasonic bathroom ventilation fans, CertainTeed’s VOC-absorbing gypsum board with anti-mildew properties, and a Unico high-velocity, high-efficiency HVAC system. The emphasis on healthy indoor air is a requirement for projects by both LivingHomes and Make It Right, and homeowners greatly benefit from it. “We have many homeowners reporting that their allergies or asthma symptoms have decreased or disappeared after moving into our homes,” says Tom Darden, Make It Right’s executive director.
Much of the three-bedroom, two-bathroom home will be constructed indoors at Palm Harbor Homes’ factory in Austin, Texas, where workers will frame, insulate, and finish the home before it ships to New Orleans. Thanks to the tight building shell and 4.2 kW PV system, the home’s electricity bills will be affordably low—something that’s crucial for Make It Right clients, Darden says. A recent study found that the nonprofit’s New Orleans homes save owners an average of $130 a month. “That means they have more money to save or spend on fresh food, health care, or ballet lessons for their kids,” he says. “Nothing makes us happier than to see these homes working on behalf of the families we serve.”
