2201 Westlake and Enso condominiums represent first mixed-use project and high-rise residential building in Seattle to earn LEED Gold certification, according to the project’s developer, Seattle-based Vulcan Real Estate.

As a LEED Gold-certified project, 2201 Westlake exemplifies sustainable innovations that promote energy and water efficiency, indoor environmental quality, eco-friendly materials selection and alternative transit options as part of a healthier workplace and living environment.

“With each new LEED-certified building, we get one step closer to USGBC’s vision of a sustainable built environment within a generation,” said Rick Fedrizzi, president, CEO & founding chair of the U.S. Green Building Council in a statement. “As the newest member of the LEED family of green buildings, 2201 Westlake is an important addition to the growing strength of the green building movement.”

Designed by Callison, the 450,000 sq. ft. mixed-use project includes 300,000 sq. ft. of high-performance, Class-A office space, 135 luxury condominiums known as Enso, 25,000 sq. ft. of street-level retail amenities, underground parking and open green space. The project was completed in July 2009.

“Earning LEED Gold status for 2201 Westlake represents an important milestone in Vulcan’s commitment to sustainability,” said Ada M. Healey, vice president of real estate at Vulcan in a statement. “As a state-of-the-art sustainable, transit-oriented development, 2201 Westlake provides long-term value not only for its tenants and residents, but also for the greater community.”

Atlanta Office Tower Employs Local Construction Materials

Tishman Speyer’s Two Alliance Center, a 30-story, 500,000 sq. ft. office tower in Atlanta’s Buckhead submarket, has been awarded LEED Gold certification by the U.S. Green Building Council.

According to the firm, approximately 15% of materials used in construction were recycled. In addition, more than 75% of the project’s construction waste was recycled and therefore diverted from landfills. The company also said that approximately 25% of construction materials were extracted or manufactured within 500 miles of the project site, thereby reducing the environmental impact from transportation.
