The Waldsee BioHaus is part of a larger effort by the Language Villages and Germany’s Deutsche Bundesstiftung Umwelt, Europe’s largest environmental foundation, to create a “Transatlantic Green Bridge” between Germany and the United States. The BioHaus promotes a dialogue and exchange of sustainable building components and technologies as well as encourages cooperative work on the development of innovative educational curricula on the subject of sustainability with emphasis on sustainable building.
