Profile: The Museum of Northern Arizona Easton Collection Center was built to store a major portion of the MNA’s treasured objects that are not on display in the exhibit building. Previously, the anthropological, biological, and fine art collections were housed in an uninsulated cement block building with inadequate climate control. A Native American Advisory Committee made key recommendations regarding the design of the new structure. Douglas fir was salvaged from collapsed railroad trestles in the Great Salt Lake for the exterior siding and custom millwork. Hydraulic lime plaster gives the exterior an adobe-like feel while still providing great strength.
Energy-saving strategy: Heating is provided by an in-floor radiant system and high-efficiency gas-fired condensing boiler while in-floor radiant cooling is served by an evaporative cooling tower. Super-efficient water source heat pumps supplement the in-floor system as needed. Control system set points allow for temperature and humidity that drift with the seasons; the interior lime plaster walls absorb excess humidity in the main collections room and release it back into the room as the humidity level drops, helping create a stable level. 75 photovoltaic solar panels are expected to offset at least 20 percent of the yearly energy costs. Additionally, the MNA has a green power contract with the local utility stipulating that 50 percent of the purchased electricity will come from renewable sources.
