24th Street Passive House Projects

Education meets community leadership in LaCrosse's first certified Passive House project

Western Technical College is a key educational institution in La Crosse, Wisconsin. Under the umbrella of construction-related studies, Western frequently develops typical family homes to expose students to hands-on practice in the field. The 24th Street Passive House Projects depart from standard construction and elevate both the educational content as well as the built homes to high-performance building practices as set forth by the Passive House building energy and GreenStar standards.

TE Studio/ Intep provided architectural and engineering services, as well as lectures and workshops for students and the community.
