2016's Harry H. Edwards Industry Advancement Award winner proves that precast concrete enables the most innovative architectural designs while providing a highly energy-efficient and durable envelope. One of the most prominent features of the building is the white precast concrete façade, which dips dramatically away from the walkway along the eastern edge, then tips back out again, much like the buildings in a Dr. Seuss story. “One of the key design challenges was to create that curved façade from precast panels,” says David Bosch, engineering team leader for High Concrete Group. The curved load-bearing design was achieved by assembling flat, traditional precast concrete panels to form a complex faceted geometry. An interlocking structural system was embedded within the panels to eliminate the need for traditional precast concrete spandrel panels. “The resulting façade creates an aesthetic versatility that is unique to the project,” Bosch says.
Villanova University Pedestrian Bridge
This collegiate pedestrian bridge harmonizes with a collegiate campus that has been around for years. The environment of a college tends to develop around them, causing a need to adapt. Taking something that was, “a necessity and turning it into an asset” was an added benefit to the Architect. Ultimately plastic and versatile, precast concrete helps designers realize their vision even when it’s not the hero in the visual. In this project, harmony, and consistency with the campus aesthetic was a high priority to both the University and the designers. To achieve this goal, the design included a fieldstone veneer to the exterior of the precast bridge following erection except for the architectural panels over the road. The panels over the existing road had the fieldstone applied by the precast manufacturer to the panel prior to being transported to the location. This helps cut down road closure time and boost efficiency.
Penn State University Hershey Campus
Inspired by the rolling hills in Pennsylvania, the eye-catching waving spandrels are the first element to greet you as you drive onto the health campus and the last you pass as you leave. Being in such prime real estate, the owners did not want this to be an ordinary parking garage. The Architects took on the challenge with inspiration from the land around them and created a total precast concrete marvel with 1,235 parking spaces with room to expand as needed.
Ohio State University Chiller Plant
Recent trends in chiller plant design that have been to use eye-catching enclosures, often glass boxes, to allow mechanical systems to be visible from outside. However, this presents the problem of cooling the chiller plant. At Ohio State University in Columbus, Ohio, a new ten-story plant uses precast concrete panels with a series of openings that allow a view inside, while keeping the interior temperature consistent and the energy use regulated.
The plant building is more than just a concrete box with openings, however. Conceived as a “House for Energy,” the envelope showcases the energy-efficient chiller equipment inside and records the sun’s energy on the exterior.
The LEED Silver Certified building features a high-polish finish and “fins” of diachronic glass that cast colored light rays across the concrete surface. The result is a dynamic façade that changes with the time of day, season, and location of the observer.
The chiller housed at the new plant facility provides chilled water production and distribution to the medical center area of the campus. The plant encloses the equipment used to maintain 12,500 tons of chilled water, with a plan to increase that capacity to 30,000 tons. Emergency power installed at the plant increases the reliability of the water production and distribution in the event of a power outage.
