The cafeteria at Brookville Intermediate School is very noisy, making conversation difficult, so the teachers challenged the students to come up with a solution.

As a Project Based Learning (PBL) opportunity the Fifth Grade Students were tasked with researching and mitigating the noise.

A local Architect invited Julie Wiebusch, Principal Acoustician/President of Greenbusch Group as a volunteer Acoustical Technical Expert to assist.

Julie and the students evaluated the acoustical qualities of the room, measured the reverberation time, discussed design, materials, and ways to reduce the noise.  The students broke out into teams and brainstormed ideas using Julie as their technical resource.  The students were amazingly creative with multiple ideas.

Once the student solutions are fully developed, the school administration will consider the students’ recommendations as they take next steps to reduce noise in the cafeteria.

Seattle Design Festival

Participating in the 2019 Seattle Design Festival (SDF), ScharrerAD and Greenbusch Group collaboratively exhibited an interactive installation as part of the "Design in the Parks" event of the SDF Block Party. Every year, the SDF program works in partnership with City of Seattle Parks & Recreation to bring "Design in the Parks" to promote public engagement, education, participation and inspiration in partnership with the local design community.

"Big Blue: in/out of Balance," was our concept for this year's interactive installation, featuring the Earth comprised of weighted blue, green and black blocks set on top of shifting boards. Blocks were color coded and weighted according to their environmental impact on the Earth. Participants were encouraged to write down sustainable and environmentally conscious ideas on the green/blue blocks, environmentally harmful ideas on the black blocks and attempt to "balance" the boards by shifting and rearranging the blocks. The installation allowed participants to consider how design can mitigate humans impact on the planet and balance the needs of all inhabitants.
