ENR2 birds eye view


Environment and Natural Resources 2 Building
Designed to look like a slot canyon and echo our sense of space in the Southwest, ERN2 exemplifies the University’s commitment to environmental sustainability, incorporating energy efficient heating and cooling systems, rainwater harvesting and low-flow faucets, and other innovative architectural solutions in a desert landscape.

Welcome to the University of Arizona's ENR2 Building

Completed in 2015, the Environment and Natural Resources 2 Building, ENR2, is part of the University of Arizona's commitment to environmental sustainability and interdisciplinary research and studies that focus on earth science, environmental programs, and natural resources. The building contains offices, classrooms, auditoriums and gathering rooms for public programs, in addition to a café and a stunning central courtyard that foster circulation and gathering. The Arizona Institute for Resilient Environment and Societies (AIRES) shares the five-story structure with the School of Geography and Development, the School of Natural Resources and the Environment, the Office of Sustainability and some divisions of the Department of Mathematics. The LEED platinum-certified building incorporates cutting-edge technologies that epitomize the university's dedication to sustainability in higher education.

To learn more about the building, including its innovative sustainable features, please visit the ENR2 page on the PDC website, or take our self-guided tour.

If you have questions regarding ENR2 room reservations, please contact Maya Patterson or email enr2roomres@email.arizona.edu.

Details of each room, including photos and individual calendars of availability, can be accessed via the table at the bottom of this page. You can select the calendar of the room you're interested below, to verify availability. *Due to the high volume of requests, we do not accept same-business-day reservations.

Important Notices for ENR2 Room Users

Requesting a room for a recurring meeting? Our BUMP CLAUSE notes that special, one-time events have priority over recurring events. AIRES reserves the right to bump with 72 hours’ notice a recurring (or, on occasion, other) event for a special, one-time event. If this occurs, we will attempt to find alternate space within ENR2 if at all possible. We will not bump regularly scheduled colloquia for building occupants (SNRE, SGD, Math).

FACILITIES MANAGEMENT NOTICE: If your event includes food/beverages at all, has more than 50 people attending, AND/OR falls on a weekend, you MUST fill out Facilities Management's Special Event Request form to notify custodial and, if necessary, specify other event needs. This will ensure your rooms are clean and the bathrooms are fully stocked and supplied. *Because custodial does not normally work on weekends, if you reserve a space on the weekend your event will incur charges via FM. Please reach out to us or Alejandra Zell on the FM Special Event team with questions about these charges.*

After filling out the FM Special Event Request form and receiving confirmation of submission, please attach confirmation to our online reservation request form or forward confirmation to enr2roomres@email.arizona.edu. If we do not receive this notification at least a week prior to your event, we reserve the right to cancel your event.
