Sustainable in Seattle

The new Ballard Blocks development in the Ballard area of Seattle offers 366,000 square feet (34,001 m2) of commercial and retail space in two buildings connected by a pedestrian promenade and below-grade parking level.

“The objective was to have a clean, modern design that met sustainable building goals as well,” according to Angela Gee, project manager for Clark Design Group PLLC, Seattle. “We wanted it to be a high-performance building both in terms of the systems and the materials.”

Approximately 51,000 square feet (4,737 m2) of Lewisville, Texas-based Metl-Span’s CFA-30 insulated wall panels were utilized. The 2-inch (51-mm) panels were finished in custom color Zactique II and were installed horizontally.

“When we researched the cladding material, we considered cost and high energy efficiency with good R value. Labor costs in the Northwest are high so using a system that reduced the labor hours made a lot of sense,” Gee said. “The Metl-Span panels provided all of the systems—the metal skin, insulation and vapor barrier—in one product. The design team was pleased with the result.”

The general contractor on the project was Ledco Construction, Henderson, Nev. Installation of the Metl-Span panels was done by Kenco Construction,

Inc., Seattle. The project is registered as LEED Silver and is in the process of being certified. Sustainabledesign elements include a high-efficiency HVAC system, low-VOC construction products, preferred parking for fuel-efficient vehicles and native and drought-tolerant plant species which enable the project to avoid installation of a costly irrigation system, as well as brownfield site remediation. Throughout construction, contractors diverted more than 93 percent of demolition and construction waste from landfills.
