The second Environmental and Natural Resources Building (ENR2) at the University of Arizona houses academic departments and interdisciplinary programs related to the study of earth sciences, natural resources, and the environment. A design brief, published in 2012, laid out a set of aspirational goals for a building that would promote interaction and collaboration among its occupants, students, and the community at large, and would reflect the university’s stewardship of its energy and water resources. It was completed in Summer 2015, and achieved USGBC LEED NC v3 Platinum certification.
