City Greenbuilding Project Case Studies

These case studies on City of Seattle capital improvement projects highlight a variety of green building approaches, design strategies, materials, and lessons learned that can help with your next project.

Airport Way Center, Building C
In the Airport Way Center, Building C, the City of Seattle makes adaptive reuse of a 125,000-square-foot high-bay warehouse for specialized police functions.

Carkeek Park Environmental Learning Center
The City of Seattle's first project to pursue a LEEDTM Gold certification is a demonstration project to educate visitors about sustainable building and the ecology of the Piper's Creek watershed.

Cedar River Watershed Education Center
The primary water source for the greater Seattle area, this watershed was designated an ecological reserve to address declining fish and wildlife and assure water supply. The sustainably built center will educate visitors on the human and natural infrastructure for water.

Cedar Water Treatment Facility Operations Building
The unique design-build-operate procurement contract used for the delivery of the overall Cedar Water Treatment Facility called for a different approach to LEED certification, one that was flexible and incentive-based. It allowed CH2M HILL, the designer, builder and operator, to find its own cost-cutting opportunities while meeting high standards for sustainability.

Fisher Pavilion at Seattle Center
Expected to host over 900,000 visitors each year, this replacement for the Flag Pavilion is the first City building completed before Seattle adopted a sustainable building policy to apply for LEEDTM Silver certification. Link to Cascadia GBC Case Study.
