The 2201 Westlake development in South Lake Union now represents Seattle’s first mixed-use and high-rise residential project to earn LEED Gold certification.

Developed by Vulcan Real Estate, 2201 Westlake was designed and constructed from the ground up using sustainable development practices.

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. Some of the sustainable features include:

• Ventilation provides office users with more control over the air and temperature in their individual spaces

• Shared high performance central energy plant with adjacent residential condominium tower that utilizes waste heat and cooling from the office space for other retail and residential uses

• Extensive use of recycled and rapidly renewable materials, low VOC paints and carpets

• Native, drought tolerant landscaping

• Water-efficient dual-flush water closets, low-flow urinals, faucets and showers designed to reduce potable water use by 35%

• Site landscaping complies with Seattle Green Streets Program, increasing pedestrian space and open green space while helping providing habitat and shade cover with large trees and native shrubs

• Exterior glass curtain wall with low solar heat gain properties provides more natural daylight than traditional office buildings
