Like many projects, the challenge for the tribe became how to get the design it wanted with the budget it had to work with.

Using insulated metal panels (IMPs) from Kingspan played an important role in achieving both those goals.

The exterior of the hospital is a mix of earth tones, blues and greens—and some rammed-earth walls made from Oklahoma’s famous red dirt.

The key design element of the building is its sweeping curved front, which was made from insulated metal panels. The design incorporates an iridescent paint scheme; the building changes color as people walk or drive by it. It’s the first time this iridescent technique was used on a building in Oklahoma, and getting the exact shade was an important—and challenging—endeavor.

“There’s a little psychology in choosing the color schemes and everything because you want to have a calming effect. It makes the patients less anxious and gives you a better reading on blood pressures and things like that,” Muscogee (Creek) Nation Principal Chief James Floyd told the local newspaper.

The hospital, architect (1Architecture) and Kingspan spent nearly a year finding the paint colors that would provide the perfect chameleon effect. The manufacturer provided hundreds of paint samples—a design advantage offered by IMPs—before all the parties agreed on Hazelnut, Rose Dust and Copper. 

Insulated metal panels can be color-matched with a full spectrum of vibrant colors available. The high-performance coatings are highly resistant to corrosion, UV light, abrasion and impacts and are maintenance-free for up to 30 years. Beyond colors, IMPs are also available in a variety of finishes—available looks include granite, copper, rustic, woodgrain and even camo.

Another design challenge on the Muscogee (Creek) National Community Hospital project was the curved front of the building. Using curved insulated metal panels would have made design and construction much easier, but would have increased costs by tens of thousands of dollars. The solution? Engineer the building so that flat panels could be “walked” around the sweeping curve of the building.

Kingspan engineered the design, utilizing panels of different lengths and widths so they could be used around the curve, which is more than 900 feet wide. The flat panels have the ability to be flexed some to accommodate a radius.

Using different panel widths was another way to keep costs down for the hospital. The majority of the panels used on the project are 2 inches; however, 1-inch panels were used in sections that cover an insulated interior wall. The thinner panels are more budget-friendly, without sacrificing aesthetics or R-value since they’re on an insulated wall.

The hospital utilizes close to 300 geothermal wells, each an estimated 300 feet deep into the ground, that use ground energy to for heating, cooling and hot water throughout the entire facility.

Insulated metal panels help meet the hospital’s goal of being as energy efficient as possible, as they provide superior thermal efficiency and will help keep both energy usage and costs down.
