    Chandler’s crew wrapped the walls with Tyvek Wrinkle Wrap and then taped the window flanges and electrical penetrations and lapped and taped the step flashings. They covered the Tyvek with two layers of 15-pound asphalt felt and then stapled lightweight fiberglass SpiderLath every 6 inches each way down the wall. They then applied a two-coat ¾-inch-thick layer of type-S stucco and sealed it with an elastomeric paint. The slab on-grade foundation is wrapped with 9-inch PolySteel ICFs with two layers of 1-inch XPS foam underneath. Tyvek: 800.448.9835. http://www2.dupont.com. Circle 348.

With five certifications and an Energy Value Housing Award from the NAHB Research Center, the project taught Chandler a lot about how different green rating systems compare in terms of stringency and ease of use (see Builder Profile)—as well as cost. He spent about $650 to comply with Energy Star and the DOE’s Builders Challenge programs, $650 more for the NGBS report card, and about $1,950 more for LEED certification.

Now that this project is complete, Chandler foresees a role for the two national programs in his business: He plans to continue to certify all of his homes to the NGBS and save LEED for only the highest-performing projects. “It seems to me there is no cause for tension between the two,” he concludes.
