The authors assess the collaboration between the University of California, Berkeley’s Community Assessment of Renewable Energy and Sustainability program and the Pinoleville Pomo Nation, a small Native American tribal nation in northern California. The collaboration focused on creating culturally inspired, environmentally sustainable housing for tribal citizens using a codesign methodology developed at the university. The housing design process is evaluated in terms of both its contribution to Native American "cultural sovereignty," as elaborated by Coffey and Tsosie, and as a potential example of the democratization of scientific practice.
