Located eight miles from Princeton, N.J., the Peddie School in Hightstown, N.J., is a private coeducational boarding school with an enrollment of 557 students. After acquiring additional land to expand athletic fields and facilities, the school sought to combine several buildings into one unified athletic center. Completed in January 2010, the structure, designed by RMJM Hillier, now houses the existing field house, fitness center, wrestling room, and pool, as well as male and female locker rooms.
Sitting at the edge of the campus, the new athletic center is “almost a proscenium to the rest of the campus,” explains design architect Barbara Hillier. To create a building that could define the school and become a “transparent edge” along the south end of the campus, Hillier sought out Illumination Arts and principal Faith Baum, with whom they had previously worked, to design the interior lighting for the pool and the public spaces.
Conceptually, the theme of water was the jumping-off point for the design, and it led to the idea of a transparent skin glowing from within. The exterior walls of the natatorium are glass, while the interior is composed of a prefabricated dual-resin sandwiched wall system with a 4-inch-interior airspace. The multilayered walls help to regulate the building temperature throughout the year, and the translucency of the resin allows plenty of daylight into the space while still providing privacy for the swimmers.
The natatorium is home to Peddie's nationally acclaimed swim team as well as the Peddie Aquatic Association, which provides community swimming classes and prepares swimmers to compete at state, regional, national, and international levels. For a facility that sees such a high level of competition, the recommended light level on the pool's surface is required to be a minimum of 50 footcandles. To achieve these levels, Baum used a high-performance 1,000W metal halide luminous linear lighting tube to achieve an even light distribution. This light-pipe system consists of an acrylic tube coated with an optical film to evenly disperse the light along the tube's 30-foot-length, with an illuminator located at one end. At 35 meters (115 feet) long, 12 tubes were required to light the length of the eight-lane pool and two tubes with a 10-foot gap at the center were needed to span the width. The light pipes are alternately switched, meaning only half as many need to be on during the day when daylight contributes to the illumination of the space. Metal halide pendant downlights illuminate the deck perimeter as well as the spectator seating. From the exterior, the translucent building appears animated and alive, and Hillier describes the entire structure as being “enlivened by the interior lighting” at night.
For special occasions only, such as an important swim meet or to celebrate a win, an additional layer of decorative lighting was designed into the façade to define both the pool and Peddie's image on campus. Pendant-hung linear fluorescent wallwashers with blue fluorescent lamps wash the perimeter walls from the interior, turning the exterior a vivid hue of blue and backlighting the school's name. This distinctive look informs the rest of the school and the community that the swim team has won their meet.
Careful selection of lighting sources and daylight harvesting allowed for an energy-efficient design solution that also met the demanding requirements of competitive swimming. Baum was excited about the idea of a luminous wall material from the project's start and sought to create “an ephemeral glowing facility” for the Peddie School that was both dramatic and sustainable. The new Peddie School Ian Graham Athletic Center signifies a win-win situation for both the school and the community as they team up to share and celebrate a passion for aquatics.
