Located in Wilmington, Del., Nemours/duPont hospital has undergone a series of expansions since its founding in the 1940s. The latest, a 450,000 square-foot addition, was designed to maintain the facility’s legacy of world-class treatment by drawing on the latest principles in health care design, including cozy, child-friendly patient rooms; welcoming, amenity-filled spaces for families and caregivers; healing gardens and large, open areas filled with abundant natural light. When FKP Architects first conceived the signature façade of the newly expanded Nemours/Alfred I. duPont Hospital for Children, his vision was to have the glass and metal framing mimic the protective framework of an arbor. A random discovery of Azuria® glass by Vitro coupled with the use of DURANAR® SUNSTORM® coatings by Vitro Alliance Partner, PPG Industrial Coatings, helped make that idea a reality. As the lead architect for the project, Paul Asteris sought to appropriate the “playful elegance” of the gardens surrounding the neighboring du Pont family mansion by placing a vast atrium at the center of the hospital and designing a bright arbor-patterned curtain wall for the exterior façade.
A combination of glass and metal coatings products, including Solarban® 70XL glass by Vitro and DURANAR® XL and DURANAR® SUNSTORM® coatings by PPG, together with a timely recommendation for tinted Azuria® glass by Vitro, not only helped him achieve those aims, but enabled the project to stay on schedule too. “The glass we were originally looking at [for the façade] had a blue/gray tint and was coming off a bit flat,” Asteris said. “By chance, a Vitro representative visiting our office saw the renderings and offered to help with some samples. He came back using Azuria® [glass] with some spandrel tones and it had the color punch we were looking for. That really helped us get the project back on track, as we were in danger of disrupting the schedule.” The aqua-blue appearance of Azuria® glass is complemented throughout the hospital by tall panels of clear Solarban® 70XL glass and in the skylights that top the soaring central atrium. The goal with both products was to bring as much daylight as possible into occupied spaces.“Numerous studies confirm that natural light is conducive to creating learning and healing environments. To us, this just seems like common sense.” The jewel-like glitter of the hospital exterior is further enhanced by the application of DURANAR® XL and DURANAR® SUNSTORM® coatings by PPG.
Solar tubes and the strategic placement of fritting on the glass façade alleviate the heat and glare of direct sunlight during the summer and channel light deeply into patient rooms to make them feel more spacious. Other green-related components in the hospital include water retention systems, roof gardens and enhanced mechanical systems. To date, the feedback Asteris has received on the hospital’s design and performance has been universally positive. “The intent was to create a facility that would set Nemours apart from other children’s hospitals. The administration wanted this to be a place where families could bring their kids to get the best care available, so we needed to create spaces that would foster a family-friendly healing environment. Anyone who visits the hospital will sense that truly is the case.”
