University Classroom Building; Duluth, Minnesota
Salmela Architect
Architect David Salmela relied on plant coverage to help maintain the strict standards of a German Passivhaus design system. Passivhaus, which utilizes a thick envelope created by insulated walls and roof and triple-glazed windows is a highly effective way to structure ultra-low energy systems. Salmela added a living roof, planted with butterfly-attracting vegetation, and surrounding tree covers to shade the building.
