Multiple metal panels clad medical center

A project goal for Banner Estrella Medical Center in Phoenix was to expand the facility, move away from copper as a primary element and maintain a cohesive aesthetic.A project goal for Banner Estrella Medical Center in Phoenix was to expand the facility, move away from copper as a primary element and maintain a cohesive aesthetic. The existing facility was skinned in a flat copper panel, precast concrete and accented with a ribbed, zinc-colored wall panel.

The 460,000-square-foot expansion project included three buildings: a patient tower and two parking garages. Morin Corp., a Kingspan Group company, supplied 35,000 square feet of its 22-gauge Matrix Series U12 vertical metal wall panel in Weathered Zinc and 13,250 square feet of its 22-gauge, pre-finished, vertical U12 Perforated Panels in Weathered Zinc.

The perforated panels have 3/4-inch holes on 1-inch stagger with a 51 percent open area; the perforation of the panels on the garages is 3/8-inch holes on 1/2-inch stagger with a 51 percent open area.

Morin's panels created a transition into the existing ribbed panels and were more cost effective than copper. The panels continued the look of the ribbed panel, provided shading to the east-and west-facing glass, and allowed views from the large patient room windows.

Morin's ribbed and perforated panels clad a window shading scrim. Kovach Inc. fabricated 20-ounce copper into its Flush Panel System with a 1/2-inch reveal; panels are 1-inch-deep by 12 inches wide. Additionally, small amounts of copper were installed at entry points into the facility, designed as a wayfinding element. The expansion included a new seven-level tower, more space for women and infant services and diagnostic and treatment areas. In all, 180,000 square feet of existing spaces were renovated. The $150 million project was completed in October 2013.
