GREEN BUILDING

RESILIENT, DURABLE, SUSTAINABLE ARCHITECTURE

built green—passive house—LEED living building challenge—Evergreen Sustainable Development Standard

We believe Green Building is architecture that lasts, and CAST is leading with high-performance, durable, and enduring buildings.

For us, as Seattle architects and enthusiasts of the Pacific Northwest environment, stewarding responsible resource management throughout the building’s lifecycle is paramount.

We work with the site and climate to shape the design, and focus on the best available building science to refine the building’s performance.

From LEED and Built Green to Passive House and the Living Building Challenge, we are well-versed in a range of green building approaches.

We take pride in helping our clients understand their choices when building for budget, performance, and longevity.
