The Builder Concept Home 2011, slated to debut as both an actual home in conjunction with the upcoming International Builders’ Show in Orlando, Fla., and as a virtual-home experience online, is a model of how and why a production home can achieve a superior level of sustainability while remaining affordable to build and buy.

The 2,667-square-foot, single-level home boasts KB Home as its builder and engages lifestyle authority Martha Stewart to add her sensible, livable, and increasingly eco-friendly style to the project.

Integrated into its good looks is an impressive lineup of energy and resource efficiencies, from a tight, durable shell and Energy Star- and Water-Sense-labeled products to a host of recycled-content and low-VOC finishes. A pair of sleek, roof-mounted solar thermal collectors serve the home’s domestic hot water needs. A 9kw array of roof-integrated solar panels entirely offset the power grid and helped the home to a HERS rating of less than zero in energy-use modeling.

KB Home is seeking the Environments for Living Certified Green label and LEED for Homes Platinum certification for the house—and yet it will price it in the mid-200s as a first move-up home. “It’s an opportunity to show our buyers that a home can be affordable, functional, and stylish,” says George Glance, president of KB Home’s Central Florida division.
