‘Das BioHaus’ is the environmental living center at Concordia Language Villages and the first building in North America to be Passive House certified. ‘Das BioHaus’ was funded in part with a grant by the Deutsche Bundesstiftung Umwelt (DBU) and serves as a living and learning facility where students and visitors are immersed in the German language, culture and the study of sciences through world-class sustainable design. Located on Turtle River Lake outside of Bemidji, Minn., the two-story, 5,000 square feet building increases living comfort significantly in terms of air quality and lack of temperature fluctuations because of its energy efficient construction. ‘Das BioHaus’ allows visitors to measure its vital signs – all in German and all in metric — through the use of extensive sensors in the entire building and a mechanical room that showcases the building’s technology. Interactive features include a building management system that monitors the building’s vital signs in real time.
