LEED BD+C: Homes v1.0 pilot
The Ladner Residence
LEED Platinum 2011
Through a complete energy retrofit and other green upgrades, Chris transformed an inefficient, out-of-date house from 1967 into a stylish, comfortable, LEED Platinum home.
The Ladner home in Little Rock, AR is a stunning example of a beautiful and sustainable house. As the owner of Viridian, a sustainable building consulting firm, homeowner Chris Ladner knew he wanted to build green when his family bought an older house that needed a complete upgrade. Chris and his wife chose to upgrade a house in the Pleasant Valley area, a walkable, tree-lined neighborhood that they both loved. Through a complete energy retrofit and other green upgrades, Chris transformed an inefficient, out-of-date house from 1967 into a stylish, comfortable, LEED Platinum home.
The Ladner home is a two-story, 2732 sq. ft. structure with four bedrooms and three and a half baths. Since LEED for Homes wasn’t really designed for remodels, some of the credits were challenging to achieve. On the other hand, remodeling an existing structure made it easier to reuse materials and earn credits for building reuse. Choosing to remodel also allowed the Ladner family to live in the neighborhood of their choice, where buildable lots no longer exist.
When Chris remodeled the house in 2011, he worked hard to make the home extremely energy efficient. In order to tighten the building’s envelope, the project team added foam insulation to the walls, attic, and roof. The team also installed an energy efficient lighting system. As a result of these measures, the home achieved a 51 HERS Index Score, which means it is about 50% more efficient than a standard new home and 80% more efficient than the average resale home. Due to its excellent energy efficiency rating, the house gained value during the appraisal: the appraiser added a line-item value of $18,000 for energy efficiency.
The Ladners also reduced waste during construction. A Habitat For Humanity Bike & Build group volunteered at the Ladner home during their trek across America to promote affordable housing. The group deconstructed the house and donated discarded materials to Habitat for Humanity, which reused them for affordable housing programs. They helped to divert more than 88% of construction waste from the landfill.
Chris worked to achieve LEED Platinum Certification because he wanted to “walk the talk” as the owner of a sustainability consulting firm. He also hoped to set an example for his kids and the neighborhood. His home shows that it is possible to achieve LEED Platinum in an existing home in a traditional neighborhood. Featured with pages of pictures in At Home Arkansas, the Ladner home has demonstrated the beautiful possibilities of sustainable design to a statewide audience.
