The Bush School’s new Upper School is the first passive house school building to be completed in the state.
Located on the private school’s Madison Valley campus, the three-story, 20,000-square-foot building has 10 classrooms and casual break-out areas on two upper levels, and a basement level with a 400-seat multipurpose room. There’s also a student lounge, student/faculty collaboration center, administrative offices and a faculty work room.
It was built using a mass plywood panel structural system to reduce embodied carbon and optimized efficiency. Mass plywood panels and glulam beams are on display throughout the learning spaces. A heavy-timber stairway leads from the basement level to each of the two primary learning levels. These also have wood clad corridors, benches and desks. Large windows maximize natural light and provide views of surrounding trees and Lake Washington.
Net zero features include two large solar arrays and energy-efficient mechanical systems.
